I recently upgraded my egcs when I installed redhat 6.0 and ever since
then, libstdc++ is not being linked into my c++ programs. How can I
change the default linking options so that libstdc++ is linked? I looked
at the specs file but couldn't understand it... :(
Thanks in Advance,
Sean

egcs doesn't link with libstdc++, only eg++ does.

Ok, that's what I should have said, the g++ that comes with the egcs
package does not link with libstdc++.

Huh? g++ has been linking in libstdc++ for years. We have not changed that
and we have no intention of changing that. If yours isn't linking in libstdc++,
then there's something majorly broken on your system.

I know something is broken, that's what I'm trying to figure out!! :)

Maybe I should have stated it differently -- something on your *system*
is busted, not egcs itself.

Perhaps I should clarify this further. If I g++ helloworld.cc, it will
compile and link, but if you run it, it will segfault. If I use ldd to
check what libraries it is linked against, it does not include libstdc++.
The problem, it would appear, is different than Glenn Gebhart's problem.
Just FYI...

Which means it *is* linked with libstdc++.

Looks like it's linked statically, with the wrong version of
libstdc++. Look for libstdc++.a in the directories searched for
libraries, and make sure it is not pointing to an old version of
libstdc++.

Ok, I only have one libstdc*.a, and that is in /usr/lib, it is
libstdc++-2-libc6.1-1.2.9.a
/usr/lib/libstdc++.so is linked to /usr/lib/libstdc++-2-libc6.1-1.2.9.0.so
/usr/lib is first in /etc/ld.so.conf
Where should I go from here?
thanks again,
Sean

This doesn't matter, lt.so.conf is only used by the run-time dynamic
linker. Run `g++ -v -Wl,-v' to re-link your program, and search for
libstdc++ in the directories that appear after -L options.
Make sure the libstdc++ links in
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66 are correct.

Both the static and dynamic version are soft links to the /usr/lib
libraries.
Here is the output (apologies for the length and the long lines...)
I don't know what is wrong, but hopefully someone else knows what to look
for.

Now go look for libstdc++* in any of the directories that appear after
-L in this list.

Now go look for libstdc++* in any of the directories that appear after
-L in this list.

I've attached the output to the bottom of this email.

Both the static and dynamic version are soft links to the /usr/lib
libraries.
Here is the output (apologies for the length and the long lines...)
I don't know what is wrong, but hopefully someone else knows what to look
for.

This doesn't matter, lt.so.conf is only used by the run-time dynamic
linker. Run `g++ -v -Wl,-v' to re-link your program, and search for
libstdc++ in the directories that appear after -L options.
Make sure the libstdc++ links in
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66 are correct.

Ok, I only have one libstdc*.a, and that is in /usr/lib, it is
libstdc++-2-libc6.1-1.2.9.a
/usr/lib/libstdc++.so is linked to /usr/lib/libstdc++-2-libc6.1-1.2.9.0.so
/usr/lib is first in /etc/ld.so.conf
Where should I go from here?
thanks again,
Sean

Looks like it's linked statically, with the wrong version of
libstdc++. Look for libstdc++.a in the directories searched for
libraries, and make sure it is not pointing to an old version of
libstdc++.

Perhaps I should clarify this further. If I g++ helloworld.cc, it will
compile and link, but if you run it, it will segfault. If I use ldd to
check what libraries it is linked against, it does not include libstdc++.
The problem, it would appear, is different than Glenn Gebhart's problem.
Just FYI...

egcs doesn't link with libstdc++, only eg++ does.

I recently upgraded my egcs when I installed redhat 6.0 and ever since
then, libstdc++ is not being linked into my c++ programs. How can I
change the default linking options so that libstdc++ is linked? I looked
at the specs file but couldn't understand it... :(
Thanks in Advance,
Sean

A problem which I am seeing on some installations is that libstdc++ is
installed as a broken link. Replacing the link to libstdc++.a in the
installation directory $prefix/lib/gcc-lib/$target/egcs-2.95/ with the actual
file will fix this.
