Re: Crash on Windows XP SP2 when not run as an administrator
On 31 Aug 2004 at 17:33, Todd O'Bryan wrote: I've tested mysql in my high school lab running from an administrator and from a student account, both from within the Cygwin terminal, and at the Windows command prompt. From the administrator account, it runs fine for hours. From the student account, it promptly (within 15 seconds or so) crashes with the same error each time. I managed to write down the error: Hi, First of all: why are you running the server from a students account? The server should be running as a system service. Open up the services control panel and check whether MySQL is listed. If it is not you need to install it by running the command c:\mysql\bin\mysqld.exe -install from a command prompt whilst logged in as an adiminstrator. You can then set the service to run automatically at boot in the services control panel ( I think this the default anyway ). Is there something that non-administrators need access to that could be causing the problem? If you REALLY need to run the server under an unprivelaged account then make sure the student has full permissions on the c:\mysql folder ( or wherever its installed) and ALL subdirectories. You may need to do more - I have never run MySQL this way (check the manual : http://dev.mysql.com) . Could it be an SP2 issue? You should also set the permissions in the new SP2 firewall so that MySQL can open TCP port 3306. Or switch it off and install a real firewall ;) Hope this helps Ian --

In any case where a row shouldn't appear unless there is a match between the keys, use an Inner Join. I wish I could be more precise than that but I don't know your particular business as well as you do. To help clarify the difference between Inner and Left Joins, I'm going to paste in part of an email I wrote last week helping someone with this point. You probably know a lot of the things in there already but I think this should help you understand the difference between an Inner Join and a Left Join.

Re: mysqldump all tables except 2 in a database
I would use the --tables option of mysqldump. It accepts more than one table name, so all you need to do is make a list of the tables you want dumped. If you are combining --tables with other options (like -B/--databases or -u or -p) make sure the --tables option is the LAST parameter in the list as everything that occurs after it will be considered a table name. details here - http://dev.mysql.com/doc/mysql/en/mysqldump.html Shawn Green Database Administrator Unimin Corporation - Spruce Pine Rhino [EMAIL PROTECTED] wrote on 08/31/2004 05:57:50 PM: - Original Message - From: Emi Lu [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, August 31, 2004 4:13 PM Subject: mysqldump all tables except 2 in a database Hello all, In mysql, do we have a way to mysqldump all tables except two in a database.

For example, in databse D1, I have 10 tables, I'd like to dump 8 of them at one time. You haven't said which version of MySQL you are using or what operating system you are running so this may not be much use to you. I am running MySQL 4.0.15 on Linux Mandrake 8.2. A bash script I posted earlier today could probably be adapted to do what you want. It acquires the names of all of the databases and takes backups of them; all you'd have to do is add an 'if' statement that excluded the two databases that you didn't want to dump.

temporary tables and replication
Hi: I'm using MySQL 4.0, and have setup replication with one server and one slave, both running LM 9.1.

Also we have several other small OLTP database on the same server. When the big job run, it would use all the physical mem and swap, all other process slow down because of this. I would like to limit the resource usage for each mysql client so that they can use only certain max amount of RAM, and don't select everything into memory before display it to users.

bad too many connections error (os x)
Hi- We've been running into a pretty serious problem for the past several versions of mysql 4.0 running on OS X (both client and server). Every once in a while we wake up to find the too many connections error coming up. There really aren't too many connections (we have our max set to 99) - it's the type of message that appears when a wrong password is used too many times (and I'm 100% sure this isn't happening). Now, the problem is that once this message starts appearing we can't even connect with mysqladmin as root. That extra connection that mysql promises doesn't exist. The only way we can shut down mysql is to perform a 'kill -9' (then restart the server and repair all the tables). And we can't reproduce this problem at will. This is driving us nuts. Before I report this as a bug I wanted to know if anyone else has seen something like this or has any suggestions of how to narrow down the problem. Thanks!

MySQL/InnoDB-4.1.4 is released
Hi! InnoDB is a MySQL table type that provides foreign key constraints, ACID transactions, row-level locking, consistent (MVCC) non-locking reads, transaction savepoints, and a commercial InnoDB Hot Backup tool to MySQL. InnoDB is included in all MySQL releases, except the commercial 'MySQL Classic' binaries. For InnoDB, MySQL-4.1.4 is mainly a bugfix release. You can download the binaries from http://dev.mysql.com/downloads/mysql/4.1.html NOTE that an upgrade from 4.0 to 4.1.3 or later requires a rebuild of some tables if you have stored control characters (ASCII value 32) to non-latin1 non-BINARY indexed columns in an InnoDB table. If you have stored control characters in an indexed non-BINARY column in a MyISAM table, you have to REPAIR or rebuild that table. There is also a rebuild need if you have used a TIMESTAMP column in an InnoDB table in 4.1.0 - 4.1.3. Functionality added or changed: * Important: Made internal representation of TIMESTAMP values in InnoDB in 4.1 to be the same as in 4.0. This difference resulted in wrong datetime values in TIMESTAMP columns in InnoDB tables after upgrade from 4.0 to 4.1. (Bug #4492) Warning: extra steps during upgrade required! This means that if you are upgrading from 4.1.x, where x = 3, to 4.1.4 you should use mysqldump for saving and then restoring your InnoDB tables with TIMESTAMP columns. No conversion is needed if you upgrade from 3.23 or 4.0 to 4.1.4 or later. * Added a new startup option innodb_locks_unsafe_for_binlog. This option forces InnoDB not to use next-key locking in searches and index scans. * Added innodb_status_file system variable to mysqld to control whether output from SHOW INNODB STATUS is written to a `innodb_status.pid' file in the data directory. By default, the file is not created. To create it, start mysqld with the --innodb_status_file=1 option. * Changes for NetWare to exit InnoDB gracefully on NetWare even in a case of an assertion failure, instead of intentionally crashing the `mysqld' server process. Also keep in mind: * Important: Starting from MySQL 4.1.3, InnoDB uses the same character set comparison functions as MySQL for non-latin1_swedish_ci character strings that are not BINARY. This changes the sorting order of space and characters ASCII(32) in those character sets. For latin1_swedish_ci character strings and BINARY strings, InnoDB uses its own pad-spaces-at-end comparison method, which stays unchanged. If you have an InnoDB table created with MySQL 4.1.2 or earlier, with an index on a non-latin1 character set (in the case of 4.1.0 and 4.1.1 with any character set) CHAR/VARCHAR/or TEXT column that is not BINARY but may contain characters ASCII(32), then you should do ALTER TABLE or OPTIMIZE table on it to regenerate the index, after upgrading to MySQL 4.1.3 or later. Bugs fixed: * Fixed a bug in ON DELETE CASCADE and ON UPDATE CASCADE foreign key constraints: long chains of cascaded operations would cause a stack overflow and crash the server. Cascaded operations are now limited to 15 levels. (Bug #4446) * Increment the InnoDB watchdog timeout during CHECK TABLE. (Bug #2694) * If you configure innodb_additional_mem_pool_size so small that InnoDB memory allocation spills over from it, then every 4 billionth spill may cause memory corruption. A symptom is a printout like below in the `.err' log. InnoDB: Error: Mem area size is 0. Possibly a memory overrun of the InnoDB: previous allocated area! InnoDB: Apparent memory corruption: mem dump len 500; hex * Fixed a glitch introduced in 4.0.18 and 4.1.2: in SHOW TABLE STATUS InnoDB systematically overestimated the row count by 1 if the table fit on a single 16 kB data page. * InnoDB created temporary files with the C library function tmpfile(). On Windows, the files would be created in the root directory of the current file system. To correct this behavior, the invocations of tmpfile() were replaced with code that uses the function create_temp_file() in the MySQL portability layer. (Bug #3998) * If you RENAMEd a table, InnoDB forgot to load the foreign key constraints that reference the new table name, and forgot to check that they are compatible with the table. * If there was little file I/O in InnoDB, but the insert buffer was used, it could happen that 'Pending normal aio reads' was bigger than 0, but the I/O handler thread did not get waken up in 600 seconds. This resulted in a hang, and an intentional crashing of `mysqld'. An outstanding bug: * If you have specified innodb_file_per_table in my.cnf, and try to create a TEMPORARY InnoDB type table, InnoDB will complain that it cannot find a path ./tmp/tablename. Workaround: create a MySQL database whose name is tmp (on Windows, temp).

I use squirrelmail, which is a php based webmail system with MySQL holdin configuration information and those connections never close, they just go inactive.

Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd-query at 0x61742d2d is invalid pointer thd-thread_id=1966159154 The manual page at http://www.mysql.com/doc/en/Crashing.html contains information that should help you find out what is causing the crash. 040901 23:38:39 mysqld ended === website provides a detailed information on it. However, I guess it's some minor and simple thing that makes me stucked here. I tried to install it on another machine, the same thing comes up. But when I try to use mysqld_safe, it's okay. But not this machine I want to run it. I used the same procedure for installation, both systems are Redhat 9 without big changes. The major difference is on the hardware. 1) This one is okay by mysqld_safe: Celeron 2.0, 256Mb DDR, 2) This one is not okay by any means: Pentium II, 128MB RAM Will you have any experience to share?

Michael We've run into this problem ourselves, also using 4.0 but on a 64bit AIX. The problem we found was that some queries were firing off threads which never ended. These threads blocked other threads, which blocked other threads... A logjam resulted with all connections ended up being used by the offending threads. The fix was to *ahem* fix our queries so they'd close their database connections once they were complete. You may wish to do a code inspection and verify that every open connection has a matching close. Hmmm. All of our connections are coming from php-generated web pages. PHP automatically closes the connection at the end of the script. Unless I completely misunderstand how this stuff works. Plus, this problem only happens once every few weeks. If some of our queries are causing this, I would expect the problem to occur more often. I'll look into this, though. Thanks, Michael You'll also find this problem if you have some badly-optimised queries, or writes that take a long time to run on a frequently-accessed table. For example, if you have a table that frequently accessed and run a slow update on it, any thread trying to read from that table will block. If you get more selects happening to that table coming in while it's still locked, your number of connections in use will shoot upwards rapidly until the slow update finishes and the table is unlocked. Have a look in your slow query log (or turn it on if it's not enabled) to look for any queries like this.

Re: Database connectivity
AFAIK, MySQL servers can only talk to other MySQL servers and that is only through the replication protocol/connections. Beyond that you will need to make your server-to-server connections through some kind of external client. Can Oracle act as a client to foreign databases? If it cannot, I believe you will need to write some code to develop a custom solution. It may be possible to use the MySQL source code to enable your custom client to behave as a MySQL replication slave then transform the binlog entries you receive into valid Oracle statements. Other than that, I think that you would need to periodically poll the MySQL server for changes and duplicate them into your Oracle server.

Re: insert/select for multiple tables...
Bruce,
Sorry, I guess I wasn't clear. I understood what you were asking, and I
thought I answered it. Your search of the mysql docs and google found
nothing about multiple-table inserts because you can't do that. I think the
mysql manual page I referenced is clear:
INSERT Syntax
INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name [(col_name,...)]
VALUES ({expr | DEFAULT},...),(...),...
[ ON DUPLICATE KEY UPDATE col_name=expr, ... ]
See? Multiple columns, but only one table.
My intent in my second paragraph was to offer help. Since there is no
multi-table insert, you need to solve your problem a different way. You'll
probably need a separate insert for each table, and possibly a temporary
table. I didn't want to guess what you need, however, based on your
example, because I wasn't sure what you really wanted to accomplish.
I suppose it might have been more helpful to offer a couple of general
suggestions. Here goes:
INSERT INTO table1
SELECT id, a.q1, b.q1
FROM a JOIN b ON a2.t=a1.t
WHERE a2.r='4';
INSERT INTO table2
SELECT id, a.q2, b.q2
FROM a JOIN b ON a2.t=a1.t
WHERE a2.r='4';
Of course, that leaves a possibility that table a or b gets changed in
between, and running the JOIN twice may not be all that efficient. This
might be better:
CREATE TEMPORARY TABLE holding
SELECT id, a.q1 aq1, a.q2 aq2, b.q1 bq1, b.q2 bq2
FROM a JOIN b ON a2.t=a1.t
WHERE a2.r='4';
INSERT INTO table1 SELECT id, aq1, bq1 FROM holding;
INSERT INTO table2 SELECT id, aq2, bq2 FROM holding;
DROP TABLE holding;
If that doesn't help you with what you need, reply with a description of the
problem to be solved, and I'm sure someone will have a solution.
Finally, about my P.S. There are many, many questions on this list that
come down to the poster not knowing/understanding JOIN vs. LEFT JOIN. They
either need a LEFT JOIN, or they always use LEFT JOIN even when they don't
need it. Perhaps you do not fall into that category, and it is perfectly
obvious to you that WHERE a2.r='4' throws away any extra (null) rows
created by the LEFT JOIN, making the LEFT JOIN equivalent to, but slower
than, a simple JOIN.

another insert/select for multiple tables... (or, determining previous auto-increment ID)
The question:
Is there anything in MySQL that will allow me to determine, accurately, the
last auto-incremented field from a particular database, so I can then insert
based upon this into another table? What if 2 users input at the same time?
Please see the 'long explanation' for further details.
Long explanation:
I've been reading over the previous thread for this. I am faced with a
similar situation and would appreciate some syntax assistance. I am only
partially finished.
I have 2 tables to insert into:
candidate
resume
When a new entry is entered via an INSERT statement I have set up, an
auto-increment integer is assigned (Candidate_ID) in the 'candidate' table.
This insert is structured in PHP:
$query = INSERT INTO candidate (Last_Name, First_Name, Middle_Initial,
Condition_Type, Employer, Country_ID, Visa_Status, Dt_Visa, MMDD_Birth, SSN,
CSG_Comments, Working, Available, Start_Date, Location, HoldOnPeriod,
Relocation, Tech_Ranking, Comm_Ranking, Availability, Cert_Comments,
Dt_Submitted, Def_Rate, Def_Rate_Unit, Other_Country, Currency_id,
Interview_Availability, Interview_Contact, US_Experience, Location_Country)
values ('$lastname', '$firstname', '$middle', '', '$Employer', '', '',
'$visa_dt', '$MMDD_Birth', '$ssn', '$csg_comments', '$working',
'$Available', '', '$location', '', '$relocation', '$Tech_Ranking',
'$Comm_Ranking', '', '$cert_comments', '', '$Def_Rate', '$Def_Rate_Unit',
'', '', '$interview_availability', '$interview_contact', '$US_Experience',
'');
$result = mysql_query($query) or die(Error: . mysql_error());
--
Now, having entered that data, I need to insert different fields from my
form into 'resume'; syntax is probably the same, but where I'm stuck is how
to determine what auto-incremented number was assigned to the entry in
candidate, so I can then insert columns based on this.
resume is structured as so:
Field TypeNullDefault
Candidate_IDint(10) Yes NULL
Section_ID int(10) Yes NULL
Section_Value longtextYes NULL
Scenario is as follows:
New entry: James Brown, is assigned 10700 for Candidate_ID and is inserted
into table 'candidate'.
Following this insert, insert is required for 6 rows of data into table
'resume':
Candidate_ID must be 10700 / Section_ID = 1 / Section_Value = some form data
from textbox
Candidate_ID must be 10700 / Section_ID = 2 / Section_Value = some form data
from a different textbox
etc. until Section_ID 6.
How would I go about setting this up for resume, now that it's set up for
candidate?
Thanks,
Eve

Hi folks, heres a real stupid question, but Im baffled. I am running MySQL v . 4.1.3b-beta-nt , JVM 1.4.2_05-b04 by SUN, Tomcat 5.0.27,Windows 2000 Server Im attempting to run SERVLETS for my application. I have a HTML form to kick off my application in Tomcat App Manager It has 2 options on it,Company Login and User Login. Company Login opens a new window to accept the Login-id and password, calls a Servlet to Open MySql, update it, close it then closes the window returning to the HTML form User Login opens a new window to accept the Login-id and password, calls a Servlet to Open MySql, update it, close it then continues on into the application My problem is this, I log into the company, it accepts all the data, opens, updates, closes Myql all with a Sqlstate = 0 (perfect) I then log attemp to log into the USER and when it attempts to open the database, it returns SQLSTATE = 08002 (connection already in use)... Any other calls to database result in SQLSTATE = 08000 (connection exception) if I back out to Tomcat App Manger, Stop the Application, then Start the application, go back into the HTML screen and choose LOGIN USER, I accept the variables, open the database, update it, and close it, all with SQLSTATE = 0. It seems, that the connection is not being released after I do updates, I get a ONE TIME connect, update... My code for the disconnect is pretty simple commit disconnect all So I thought, maybe I need a QUIT statement, I changed to.. Commit Quit Disconnect all The QUIT command throws an SQLSTATE = 42000 (invalid syntax) Is QUIT not supported under MYSQL can anyone ofer me CLUES as to why it may not be Disconnected successfuly Im desperate here Mike
Re: another insert/select for multiple tables... (or, determining previous auto-increment ID)
Since you should still have the same information that you used to create
your entry in the candidate table you can do something like:
SELECT @candidateID := Candidate_ID
FROM candidate
WHERE Last_Name = '$lastname'
AND First_Name = '$firstname'
AND Middle_Initial = '$middle'
INSERT INTO resume (Candidate_ID, Section_ID, Section_Value)
VALUES (@candidateID, 1, '$field1'),
(@candidateID, 2, '$field2'),
(@candidateID, 3, '$field3'),
(@candidateID, 4, '$field4'),
(@candidateID, 5, '$field5'),
(@candidateID, 6, '$field6');
If you use this format, you have to worry about your field data (field1
through field6) messing with your single quotes. This is especially true
as I think those are user-entered fields, right? I can't think of it off
the top of my head but I believe that PHP already has a function that will
safely escape text strings so that they are INSERTable into MySQL using
single quotes (sorry for the brain freeze).

The question:
Is there anything in MySQL that will allow me to determine, accurately,
the
last auto-incremented field from a particular database, so I can then
insert
based upon this into another table? What if 2 users input at the same
time?
Please see the 'long explanation' for further details.
Long explanation:
I've been reading over the previous thread for this. I am faced with a
similar situation and would appreciate some syntax assistance. I am only
partially finished.
I have 2 tables to insert into:
candidate
resume
When a new entry is entered via an INSERT statement I have set up, an
auto-increment integer is assigned (Candidate_ID) in the 'candidate'
table.
This insert is structured in PHP:
$query = INSERT INTO candidate (Last_Name, First_Name, Middle_Initial,
Condition_Type, Employer, Country_ID, Visa_Status, Dt_Visa, MMDD_Birth,
SSN,
CSG_Comments, Working, Available, Start_Date, Location, HoldOnPeriod,
Relocation, Tech_Ranking, Comm_Ranking, Availability, Cert_Comments,
Dt_Submitted, Def_Rate, Def_Rate_Unit, Other_Country, Currency_id,
Interview_Availability, Interview_Contact, US_Experience,
Location_Country)
values ('$lastname', '$firstname', '$middle', '', '$Employer', '', '',
'$visa_dt', '$MMDD_Birth', '$ssn', '$csg_comments', '$working',
'$Available', '', '$location', '', '$relocation', '$Tech_Ranking',
'$Comm_Ranking', '', '$cert_comments', '', '$Def_Rate',
'$Def_Rate_Unit',
'', '', '$interview_availability', '$interview_contact',
'$US_Experience',
'');
$result = mysql_query($query) or die(Error: . mysql_error());
--
Now, having entered that data, I need to insert different fields from my
form into 'resume'; syntax is probably the same, but where I'm stuck is
how
to determine what auto-incremented number was assigned to the entry in
candidate, so I can then insert columns based on this.
resume is structured as so:
Field Type Null Default
Candidate_ID int(10)Yes NULL
Section_ID int(10)Yes NULL
Section_Value longtextYes NULL
Scenario is as follows:
New entry: James Brown, is assigned 10700 for Candidate_ID and is
inserted
into table 'candidate'.
Following this insert, insert is required for 6 rows of data into table
'resume':
Candidate_ID must be 10700 / Section_ID = 1 / Section_Value = some form
data
from textbox
Candidate_ID must be 10700 / Section_ID = 2 / Section_Value = some form
data
from a different textbox
etc. until Section_ID 6.
How would I go about setting this up for resume, now that it's set up
for
candidate?
Thanks,
Eve

Re: another insert/select for multiple tables... (or, determining previous auto-increment ID)
Yes, LAST_INSERt_ID(). It's connection-specific, not db-specific. Because
it is connection-specific, your 2-users issue is avoided. See the manual
for the details http://dev.mysql.com/doc/mysql/en/Getting_unique_ID.html.

Every once in a while we wake up to find the too many connections error coming up. There really aren't too many connections (we have our max set to 99) - it's the type of message that appears when a wrong password is used too many times (and I'm 100% sure this isn't happening). Now, the problem is that once this message starts appearing we can't even connect with mysqladmin as root. That extra connection that mysql promises doesn't exist. The only way we can shut down mysql is to perform a 'kill -9' (then restart the server and repair all the tables). And we can't reproduce this problem at will. This is driving us nuts. Before I report this as a bug I wanted to know if anyone else has seen something like this or has any suggestions of how to narrow down the problem. Thanks! Michael We've run into this problem ourselves, also using 4.0 but on a 64bit AIX. The problem we found was that some queries were firing off threads which never ended. These threads blocked other threads, which blocked other threads... A logjam resulted with all connections ended up being used by the offending threads. The fix was to *ahem* fix our queries so they'd close their database connections once they were complete. You may wish to do a code inspection and verify that every open connection has a matching close. Hmmm. All of our connections are coming from php-generated web pages. PHP automatically closes the connection at the end of the script. Unless I completely misunderstand how this stuff works. Plus, this problem only happens once every few weeks. If some of our queries are causing this, I would expect the problem to occur more often. I'll look into this, though. Thanks, Michael You'll also find this problem if you have some badly-optimised queries, or writes that take a long time to run on a frequently-accessed table. For example, if you have a table that frequently accessed and run a slow update on it, any thread trying to read from that table will block. If you get more selects happening to that table coming in while it's still locked, your number of connections in use will shoot upwards rapidly until the slow update finishes and the table is unlocked. Have a look in your slow query log (or turn it on if it's not enabled) to look for any queries like this.

Re: Server hanging
Back in 3.23.x we used to see MySQL hang on a corrupt table (typically caused by an improper shutdown). A kill -9 was needed to stop the process, upon restart we'd run a mysqlcheck (MyISAM tables) and repair the table. We didn't see anything obvious in the logs except the last query, which was attempting to use the corrupt table.

hosted application data design
Hi all, I'm designing a hosted application that many clients will access. I've got all sites running off one PHP code base quite nicely, and now I'm hoping to reduce the multiple databases down to just one shared DB. (Note: at this stage, all accounts are fictional, so there's no legacy data to worry about). So instead of each account have it's own database and autonomous tables, I'd like all accounts to share one database. This will: - make updates easy - allow each account to be group aware - allow a parent website easy access to all account data I've added client_id columns to all tables, and things are working fine, with the following exception... I'm worried about the primary keys (IDs) for each table growing to an unmanageable size pretty quick... 50 accounts * 500 forum posts = 25000 IDs pretty quickly. 50 sites * 5000 members = 250,000 members. I'm sure this isn't much of a technical/performance issue (with proper indexing), but it's just strikes me as a little strange that the first news post for an account could have an ID of '502846', rather than '1'. So, I was hoping I might be missing something in regards to primary keys... Can a primary key (or unique key) be established on two columns (eg primary key = client_id + post id)? Can an auto-increment column only increment in relation to the client id? Or am I expecting *way* too much out of MySQL and relational data design? --- Justin French http://indent.com.au -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I am getting the following problem / error : --- /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x1ade): In function `store_param_time': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x1ba2): In function `net_store_datetime': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x1beb): In function `store_param_str': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x2428): In function `mysql_stmt_bind_param': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x2a01): In function `fetch_result_bin': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(libmysql.o)(.text+0x2a36): more undefined references to `_intel_fast_memcpy' follow /usr/local/mysql/lib/libmysqlclient.a(my_vsnprintf.o)(.text+0x22a): In function `my_vsnprintf.': : undefined reference to `_intel_fast_memset' /usr/local/mysql/lib/libmysqlclient.a(ctype.o)(.text+0x1b3): In function `cs_value': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype.o)(.text+0x218): In function `cs_value': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype.o)(.text+0x714): In function `cs_value': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype.o)(.text+0x740): In function `cs_value': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-simple.o)(.text+0xf2b): In function `my_long10_to_str_8bit': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-simple.o)(.text+0x1053): more undefined references to `_intel_fast_memcpy' follow /usr/local/mysql/lib/libmysqlclient.a(ctype-simple.o)(.text+0x1495): In function `my_fill_8bit': : undefined reference to `_intel_fast_memset' /usr/local/mysql/lib/libmysqlclient.a(ctype-bin.o)(.text+0x51b): In function `my_strnxfrm_bin': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-ucs2.o)(.text+0x1eb5): In function `my_strnxfrm_ucs2_bin': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-tis620.o)(.text+0x58): In function `my_strnncoll_tis620': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-tis620.o)(.text+0x6e): In function `my_strnncoll_tis620': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-tis620.o)(.text+0x12e): In function `my_strnncoll_tis620': : undefined reference to `_intel_fast_memcpy' /usr/local/mysql/lib/libmysqlclient.a(ctype-tis620.o)(.text+0x239): more undefined references to `_intel_fast_memcpy' follow collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1 I have installed the Intel compiler and added the /opt/intel_cc_80/lib to the LD_LIBRARY_PATH environment variable.
