libstdc issue

[Koornstra, Reinoud]

Hi Ian,

Thanks for your answer.
Actually I tried to do it like this:

./configure --prefix= --exec-prefix= --enable-languages=c,c++

Hence, I would suspect after the make and make install it would have overwritten any library.
Also also have the gcc in /usr.
However, in ld.so.conf, first /bin is called so I would expect that always first /bin is being searched for any lib.
How to check what versions of gcc libs are installed?
Any hints on repairing this issue?
Kind Regards,

Reinoud.

gcc does not normally install libgcc_s.so.1 in /lib, so my guess is that
that file came from your OS, and your dynamic linker is finding it
before the libgcc_s.so.1 which was installed by gcc.  You could try
making it a symlink to the libgcc_s.so.1 which you installed.

Note that you can confuse systems by building and installing gcc into
system directories like /lib, overwriting the system libraries and
compilers.  It's often better to install gcc and use it elsewhere.
