compiling with libstdc++.a that "could not read symbol"

Hi there,

I have a question on my linux box where I cant link properly. I’ve tried configure option --enable-shared or --disable-shared.
The following are the message I got. Is there anything I can do to fix this linking/lib problem?
thanks in advance,
Tim

ps.

Hi Tim,

llvm[3]: Linking Debug+Asserts Loadable Module LLVMHello.so
/depot/qsc/QSCF/bin/ld:
/linux/depot/gcc-4.2.2-static/bin/../lib/gcc/x86_64-redhat-linux/4.2.2/../../../../lib64/libstdc++.a(string-inst.o):
relocation R_X86_64_32 against `std::basic_string<char, std::char_traits<char>,
std::allocator<char> >::_Rep::_S_empty_rep_storage' can not be used when making
a shared object; recompile with -fPIC

libstdc++.a wasn't built with -fPIC, so can't be linked with when building
a shared library (in this case LLVMHello.so). So this looks like a problem
with your GCC installation, not with LLVM. I expect you to have the same
problem when building any shared library that needs to link with libstdc++.

Ciao, Duncan.
