I just read the 4.0 docs of MySQL. Apparently, mysql_connect is deprecated. mysql_real_connect should be used instead.
http://www.mysql.com/documentation/mysql/bychapter/manual_Installing.html#Up grading-from-3.23 http://www.mysql.com/documentation/mysql/bychapter/manual_Clients.html#mysql _real_connect So, the MySQL provider in Mono will have to be modified to use mysql_real_connect somehow. I wonder how the MySQL provider could handle two different versions of a client library. I also wonder how in C# how the runtime could gracefully handle when a native function is not found in a library. Currently, the provider calls mysql_thread_end() when Closing a connection, but if the client library doesn't have mysql_thread_end, mono crashes. Any ideas? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Rolf Tollerud Sent: Saturday, January 04, 2003 12:41 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: SV: [Mono-list] MySQL Data Provider for MySQL (Mono 0.17) Thanks Morgan that could very well be the problem because I am using MySQL4.07! -----Ursprungligt meddelande----- Fr�n: Daniel Morgan [mailto:[EMAIL PROTECTED]] Skickat: den 4 januari 2003 10:28 Till: Steven Balthazor; 'Rolf Tollerud'; [EMAIL PROTECTED] �mne: RE: [Mono-list] MySQL Data Provider for MySQL (Mono 0.17) Hmmm... I'm not sure. What version of the MySQL client library are you using? Where did you get it? The MySQL provider in mono was built for the Production version of MySQL 3.23.xx. I wonder if there is a tracing or debugging mechanism in mono we could use to see what it is doing. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Steven Balthazor Sent: Friday, January 03, 2003 3:36 PM To: 'Rolf Tollerud'; [EMAIL PROTECTED] Subject: RE: [Mono-list] MySQL Data Provider for MySQL (Mono 0.17) I had a similar problem (if I remember correctly). To get it to compile correctly on Linux I had to add a link from /usr/lib/libmysqlclient.so to /usr/lib/libmySQL.so e.g.: ln -s libmysqlclient.so libmySQL.so Cheers, Steven Balthazor -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Rolf Tollerud Sent: Friday, January 03, 2003 1:02 PM To: [EMAIL PROTECTED] Subject: [Mono-list] MySQL Data Provider for MySQL (Mono 0.17) When I try to run MySqlTest (which compiles just fine) on windows XP I get following error messages: (mono MySqlTest.exe) ** (MySqlTest.exe:3924): WARNING **: Failed to load function mysql_connect from libmySQL ** (MySqlTest.exe:3924): WARNING **: Failed to load function mysql_connect from libmySQL Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object in <0x00025> 06 Mono.Data.MySql.MySql:Connect (intptr,string,string,string,string,uint,string,uint) in <0x003e6> 00 Mono.Data.MySql.MySqlConnection:Open () in <0x00057> 00 Test.Mono.Data.MySql.MySqlTest:Main (string[]) Why will it not load mysql_connect?
