./libgcc_s.so.1 => not found, mainline broken?!?

./libgcc_s.so.1 => not found, mainline broken?!?

[Paolo Carlini]

Hi,

something is currently broken in mainline wrt LD_LIBRARY_PATH and 
libgcc. Is this known?!?

I'm seeing the problem with g++: the executable cannot find its 
libgcc_s.so.1
I.e., for a build:

    --prefix=/usr/local/gcc-exp

and

    LD_LIBRARY_PATH=/usr/local/gcc-exp/lib: ...

I'm now seeing, invariably:

paolo:~/Work> a.out
a.out: error while loading shared libraries: ./libgcc_s.so.1: cannot 
open shared object file: No such file or directory
paolo:~/Work> ldd a.out
        libstdc++.so.6 => /usr/local/gcc-exp/lib/libstdc++.so.6 (0x40017000)
        libm.so.6 => /lib/libm.so.6 (0x40100000)
        ./libgcc_s.so.1 => not found
        libc.so.6 => /lib/libc.so.6 (0x40122000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
        ./libgcc_s.so.1 => not found

Note that libgcc_s.so.1 *is* correctly installed in 
/usr/local/gcc-exp/lib/, only, the executable for some reason cannot 
find it :-(

Thanks for any feedback,
Paolo.

The one I posted earlier today, 
http://gcc.gnu.org/ml/gcc/2004-11/msg01197.html, might be related to 
this issue.

I see, thanks... Anyway, in the meanwhile I learned that the issue is known
and Zack is already working on it:

    http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02674.html

Note the "./" before libgcc_s.so.1.  Probably Zack's patch.

Ah, you are right, I'm blind today! ;)

Yes, most probably.

Thanks,
