gcc 3.3.2, shared library

luzi82 · 12-21-2003, 07:58 AM

using Debian 3.0r1
using kernel 2.4.23
using gcc 3.3.2
I wish to make a helloworld using c++'s cout.
compile ok using g++
but error when execute:

Code:

./a.out: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

odd, the libstdc++.so.5 exist in /usr/local/lib/
when I copy this file into /usr/lib/ for test
it return another error:

Code:

./a.out: /lib/libgcc_s.so.1: version `GCC_3.3' not found (required by /usr/lib/libstdc++.so.5)

I guess the error is caused by linux do not realize there exist a shared library in /usr/local/lib/
something more strange, redhat do not make the same error!! (so I think it is a debian problem...)

how can I fix it?
thx.

well, i think the problem is probably that there is a line:
/usr/local/lib
missing in /etc/ld.so.conf
Put it there and type ldconfig. Hopefully it works(maybe)
