Maybe I'm still missing something, but I cannot observe the behaviour
that you report. When I compile
#include <vector>
struct A
{
};
int main()
{
vector<A> x;
vector<A>::iterator i= x.begin();
A& a = *i;
}
with g++ 2.95.2, it compiles just fine.

Yes, for vector, it has no error, but for set,
it has errors and warnings.

Subject: binutils 2.9.5.0.24 is released
This is the beta release of binutils 2.9.5.0.24 for Linux, which is
based on binutils 2000 0113 plus various changes. It is purely for
Linux, although it has been tested on Solaris/Sparc and Solaris/x86
from time to time.
I am planning to make the public release soon. Please test it as much
as you can.
Please report any bugs related to binutils 2.9.5.0.24 to [EMAIL PROTECTED]
For arm-linux targets, there are some important differences in behaviour
between these tools and binutils 2.9.1.0.x. The linker emulation name has
changed from elf32arm{26} to armelf_linux{26}. Also, the "-p" flag must be
passed with the linker when working with object files (or static libraries)
created using older versions of the assembler. If this flag is omitted the
linker will silently generate bad output when given old input files.
To get the correct behaviour from gcc, amend the *link section of your specs
file as follows:
*link:
%{h*} %{version:-v} %{b} %{Wl,*:%*} %{static:-Bstatic} %{shared:-shared
} %{symbolic:-Bsymbolic} %{rdynamic:-export-dynamic} %{!dynamic-linker:
- -dynamic-linker /lib/ld-linux.so.2} -X %{mbig-endian:-EB} %{mapcs-26:-m ar
melf_linux26} %{!mapcs-26:-m armelf_linux} -p

Subject: problems with linking
hi
I've created two libraries (static ones)
and the second one uses a function from
the first one.
I normally link them like this
ar r lib1.a lib1.o
ranlib r lib1.a
ar r lib2.a lib2.o
ranlib r lib2.a
then I try to link my program like this
gcc -o program program.o -l1 -l2
The linker keeps telling me that it's
impossible to find the function called
in the second library which is normally
present in the first one. Everything starts
to work when I call this function in program.c.
Does anybody know how to solve this ?
Thank You.

hi
Is it possible to debug a program remotely

real network with ethernet cards, not serial
cable) ?
The program uses svgalib, so it's difficult to
debug it normally.

gcc -o program program.o '-Wl,-(,-l1,-l2,-)'
from info ld:
`-( ARCHIVES -)'
`--start-group ARCHIVES --end-group'
The ARCHIVES should be a list of archive files. They may be
either explicit file names, or `-l' options.
The specified archives are searched repeatedly until no new
undefined references are created. Normally, an archive is
searched only once in the order that it is specified on the
command line. If a symbol in that archive is needed to resolve an
undefined symbol referred to by an object in an archive that
appears later on the command line, the linker would not be able to
resolve that reference. By grouping the archives, they all be
searched repeatedly until all possible references are resolved.
Using this option has a significant performance cost. It is best
to use it only when there are unavoidable circular references
between two or more archives.

I don't see why not. For instance, you can fire up gdb in a telnet
session and give it the program file and pid of the process you are
trying to debug, and it should attach that process.
A serial cable over which you run ppp or slip is just as much a network
as a 2 node ethernet lashup.

Reverse the order in which the libraries are linked:
gcc -o program program.o -l2 -l1
GNU ld (the linker called by gcc) will link in only what is needed
up until the current point. If program.o doesn't call anything in
lib1, then lib1 will be ignored in your original comand line. The
linker then moves on to lib2, which is needed because program.o
references something in it. If this generates a dependency on a
symbol in lib1, that will go unresolved, because the linker does not
go back and try lib1 again. Each library is linked once, in the order
given on the command line. If you want the linker to try a library
multiple times, you must list it multiple times on the command line,
as in:
gcc -o program program.o -l1 -l2 -l1
This is perfectly legal, and in fact, used all the time by gcc for
its own internal and standard libraries.

Subject: Re: problems with linking
In fact, most/all linkers work this way. For example, libXm
the motif library contains symbols that duplicate symbols in
libXt (i.e. 'overload' them). Thus linking -lXm -lXt will
produce correct libraries, whereas -lXt -lXm will create apps with
weird coredumps/bad behaviour.

Hello one :-)
Why would you want to? I think you would have to run it as a
cross-compiler, meaning it (the compiler) would have to have been
configured with a target of i386-*-linux-gnuaout or so. You can see
what targets you have available with ls /usr[/local]/lib/gcc-lib, but I
doubt any stock distro compiler bothers with a.out on x86 any more. You
could install the source for the compiler, configure it for a.out, and
build and install it, but it seems like a lot of work.

Subject: bugfix: incorrect va_arg() definition for 32bit MIPS
Hi.
I have been building gcc 2.95.2 on 32bit MIPS/Linux box.
During this work, I found a inverted 'ifdef' on defining
va_arg() macro in gcc/ginclude/va-mips.h.
That is, definition of va_arg for 32bit little endian and 32bit big
endian is inverted.
You can repeat this problem running a attached test program.
I guess gcc on IRIX 5.? or O32 ABI box has same problem.
Have you ever experienced same problem on 32bit MIPS box?
Sample fix is attached at the bottom.
VERSION:
gcc 2.95.2 on MIPS/Linux
gcc 2.7.2 on MIPS/Linux
egcs-1.0.2 on MIPS/Linux

EHLO!
On a newsgroup one person had the following problem:
He wanted gcc to issue warning about unused functions of a program.
Is it possible at all?
If not, then will it be possible one day? :)

This is a linux 2.3.40 running on x86, glibc 2.1.2
gcc 2.95.2 installed manually. What can be the problem?
My gcc's configure options was the following:
- --prefix=/usr

- --enable-cpp

C++ decorates the names of the functions with its type and parameters.
You have to use C linkage for those functions.

You can find documentation on this at http://www.postgresql.org
What you are looking for is documentation on "libpq". "libpq" is a C
programming interface to Postgresql providing functionality that you can use
from your C program.
If you have Postgresql installed on your system this should also be part of
your user documentation.

Subject: VIRUS ALERT! THIS IS NOT A DRILL!
Hello to EVERYONE in my address book:
Yesterday I was hit by a "virus" that may have replicated and mailed itself to
everyone in my address book. I'm very sorry about this. I didn't send this
out right away, because I wanted to know what to do about it FIRST. With that
in mind, here's the scoop.
The file was actually a script, written in Visual Basic. A standard scan with
McAfee will NOT pick this file up, because it has an odd extension, .VBS.
This is not a binary, it's text, so removal is simple. One copy of the script
is renamed RUNDLL.VBS and is stored in your \WINDOWS\SYSTEM or \WINNT\SYSTEM32
(on NT systems) folder. Removal is simple, just delete the file. The other
copy of the file will reside in your TEMP directory, I.E. \WINDOWS\TEMP, which
is where mine was. Note that the second copy will NOT be named RUNDLL, but
will have the same extension of .VBS and is easily found and removed as no
other file in that directory should have that extension.
HOW DO I KNOW I HAVE THE SCRIPT/VIRUS?
A message will show up on your system, from me (not actually, from the script
really) saying "Enjoy the links". It will have a file attachment, which is
the afore mentioned file. CLICKING ON IT will LAUNCH the virus, and offer to
put XXX links on your desktop. If this happened to you, you have the
script/virus and need to follow the directions above (or below for you
non-techies out there) and clean your system.
For the NON-TECHNICAL who get this message:
READ ALL DIRECTIONS BEFORE PROCEEDING! IF YOU CAN'T FIGURE IT OUT, CALL ME
FOR HELP!
Go and Download McAfee 4.0 from ftp.mcafee.com , http://www.mcafee.com/ or
similar. Be sure you download the latest scan.dat file. Install McAfee, and
then the latest scan.dat file. You may get an error telling you the file is
locked! If so, you must restart your machine in MS-DOS mode, and manually
copy the file scan.dat to the McAfee Directory. Be sure to write down where
that is when you first install McAfee so you know where to copy the file to!
You will also need either pkzip or WinZip (http://www.winzip.com/ ) to open
the file the new dat files are in. Tell it so scan all files, and the
script/virus if present will be deleted my McAfee. I have not tested any
other scanners, but I'm sure if you have current files, you should be fine
with Dr. Solomon, Norton, etc.
Again, I'm very sorry about this, and regret any inconvenience this may have
caused.
Sincerely,
Scott

Subject: binutils 2.9.5.0.27 is released.
This is the beta release of binutils 2.9.5.0.27 for Linux, which is
based on binutils 2000 0204 plus various changes. It is purely for
Linux, although it has been tested on Solaris/Sparc and Solaris/x86
from time to time.
I am planning to make the public release soon. Please test it as much
as you can.
Please report any bugs related to binutils 2.9.5.0.27 to [EMAIL PROTECTED]
For arm-linux targets, there are some important differences in behaviour
between these tools and binutils 2.9.1.0.x. The linker emulation name has
changed from elf32arm{26} to armelf_linux{26}. Also, the "-p" flag must be
passed with the linker when working with object files (or static libraries)
created using older versions of the assembler. If this flag is omitted the
linker will silently generate bad output when given old input files.
To get the correct behaviour from gcc, amend the *link section of your specs
file as follows:
*link:
%{h*} %{version:-v} %{b} %{Wl,*:%*} %{static:-Bstatic} %{shared:-shared
} %{symbolic:-Bsymbolic} %{rdynamic:-export-dynamic} %{!dynamic-linker:
- -dynamic-linker /lib/ld-linux.so.2} -X %{mbig-endian:-EB} %{mapcs-26:-m ar
melf_linux26} %{!mapcs-26:-m armelf_linux} -p

Subject: gcc v2.95.2 behavior
I have a strange behavior at compile time for the same project with :
- - gcc v. pgcc 2.91.66 running on linux 2.2.9-19mdk : compile ok
- - gcc v. 2.95.2 running on linux 2.2.14-15mdk : cannot compile; results in a lot of
errors
In fact, gcc v. 2.95.2 includes the following:
/usr/lib/gcc-lib/i586-mandrake-linux/2.95.2/include/asm/posix_types.h
instead of
/usr/include/asm/posix_types.h
This special include seems to be intended to fix a bug in _FD_ZERO for glibc-1.x.
However, it includes <features.h> which prevents many data types to be defined.
To force these typedefs, I need to compile with -D_LOOSE_KERNEL_NAMES.
I'm compiling code for a kernel module and other options are :
- -DMODVERSIONS -DCONFIG_KERNELD -DMODULE -D__KERNEL__ -DLINUX -D__NO_VERSION__
I would like to know whether it's a temporary problem related to this gcc version, or
a conflict with my compiler options.
Thanks for your help,

Subject: C++ executable linked with libm
Hi all,
Could somebody tell me, why all c++ executables linked with libm.
Even the simplest one of the form '#include<iostream> main() { cout <<
"hello" << endl;}' .
(Besides this , from the output of 'ldd' it's possible to see that the same
executable is linked with libc , but not with stdc++)
If I use C counterpart program like '#include<stdio.h> main() {
printf("hello\n");}' the libm is not linked with the executable.
I use gcc/g++ -2.95.2 and ldd-2.1.1
Thanks,
Uri
BTW I have try to do the same with pgcc-2.95.2 , and eventhough it still
links the executable with libc and libm , but it links
the libstdc++ as well , contrary to gcc-2.95.2

Hi,
I've uploaded the fourth (and hopefully last) test release for glibc 2.1.3
to
ftp://sourceware.cygnus.com/pub/glibc/snapshots
You can find the files
glibc-2.1.3pre4.tar.bz2 (also .gz)
and
glibc-linuxthreads-2.1.3pre4.tar.gz
(All my alternative sites are not reachable or changed. So use
sourceware and its mirror sites.)
The crypt add-on hasn't changed. (And I have not yet a word from a
legal people whether I can include the code in the main sources.)
Since pre3 we added quite a lot of bug fixes and we now feel very
strongly that the sources are very stable, more stable than anything
before. Especially people doing heavy thread work should try it.
If no major problems are reported I'll make an official release soon.
Please send feedback (nagative *and* positive to
[EMAIL PROTECTED]).

Hello,

Not all, but most C++ programs are linked with libstdc++. The shared
libstdc++.so library unconditionally depends on libm.so (because a few
functions within it require math functions), so what you see is
normal.
It may be possible to link parts of libstdc++ _statically_ into a
program _without_ bringing in libm, but with dynamic linking libm will
always be required.

You may want to try the version in
http://gcc.gnu.org/ml/gcc/2000-02/msg00448/sstream,
or you can try libstdc++ v3.

gcc.gnu.org, sourceware.cygnus.com.

In C and C++, declarations are used to introduce variables, functions
and the like. Every declaration has a name. For example,
int x;
declares a variable, and gives it a name (x). If you just write
int;
you get such an error: the declaration does not declare anything.

Pardon me? Why is the namespace implementation in g++ not according to
the standard? Give examples.
If you are referring to the treatment of 'namespace std': This is an
extension, which can be turned of with -fhonor-std. On all other
namespaces, g++ behaves conforming.

Again, don't make such claims without foundations. Examples?
Also, it is primarily an ISO standard, not an ANSI one.

What about it? There is no such header in standard C++.

I'm not afraid of that. When it comes to the compiler proper, I know
of no competition that is closer to the standard than g++ (EDG
compilers are on a similar level, though).
For the library, libstdc++ v3 should be much better than the current
one.
If all you wanted is to vent your frustration, I feel sorry that I
wasted my time responding to you.

To all readers on the list:
If you don't know it already, Stroustrup's book, though wonderful, is flawed. I am
referring to "The C++ Programming Language". Make sure you get the errata before you
waste someone's precious time. Sorry Martin... :(

YOU ARE RIGHT! My mistake... I investigated further... sorry about that.
I *did* upgrade GCC fairly recently (a month), so maybe my problems with
that was pre-egcs 1.1.*. Sorry about that... Hey... this is how I learn! :)

I am going by Stroustrup.... I finally checked out his various errata! He made
a number of mistakes, including this one. egcs is correct! If interested
the error is on page .... 51. And makes perfect sense in retrospect.

Again, you are right! Stroustrup typo-ed again! Page 119, 1st paragraph! Now, this
BOOK is frustrating me a bit.

Great!

I am sorry you did waste your time! I should have looked at the errata for Stroustrup
sooner, and should have tried out namespaces again after the upgrade. No, I didn't
*just* want to vent. I did really want to get to the bottom of some of these issues.
And I still would love to see a implemented/
not implemented features list.
I appreciate your time. You have educated me, and I value that. To me it was not a
waste of time, but I am sure you see it otherwise. I appologize. We are not all gurus,
you know... not yet anyway. :)

You didn't say what Linux distribution (redhat, debian, suse) you are
using. It looks like an error that /usr/i386-linux/bin/ld is invoked -
why does it not invoke /usr/bin/ld. Also, crt1.o should be found in
/usr/lib/crt1.o.
Most likely, you forgot to install essential files on your system. On
a redhat system, crt1.o is part of the glibc-devel package;
/usr/bin/ld is part of the binutils package. Make sure these packages
are installed on your system.

Martin

Subject: Re: warning stuff
> He wanted gcc to issue warning about unused functions of a program.
> Is it possible at all?
If the functions are static, gcc will warn if they are not used. So
making 'potentially unused' functions static will allow a better
diagnosis.
If you want to know which extern functions are unused, the compiler
cannot decide it on its own - you have to wait until you see the
linker line to know what is used and what is not.
To omit unused functions during linking, one approach is to pass
- -ffunction-sections to the compiler, and --gc-sections to the
linker. That only works for -static linking.
With this approach, it is also possible to find out functions removed
during linking: Invoke nm on the resulting executable, and on each
input object file. Comparing the symbol lists gives you the unused
functions.

Martin

Subject: glibc 2.1.3
I've uploaded the 2.1.3 release of glibc to
ftp://sourceware.cygnus.com/pub/glibc/releases
There you can find the files
glibc-2.1.3.tar.bz2 (also .gz)
glibc-2.1.2-2.1.3.diff.gz
glibc-linuxthreads-2.1.3.tar.gz
There is no new crypt add-on since it hasn't changed.
This release fixes many bugs in all parts of the library and everybody
is encouraged to update. Preferably through your distribution
provider since compiling glibc yourself means taking a risk unless you
know exactly what you are doing.
This release should be fully compatible (both directions) with glibc
2.1.2. The only part which changed is the format of the files
containing the locale data. This can be easily fixed by running the
`localedef' program for the locales which get used on the system (or
by running `make localedata/install-locales' to update all of them).
