Error linking with GCC 4.3.2 on RHEL 5.3 and libstdc++.so. Any GCC gurus?

Question

Trying to use the RHEL5.3 GCC 4.3.2 compiler to build my software on that platform. I get the following error no matter what I try when compiling with -O2, but it builds fine without optimization. Any ideas?

/usr/bin/ld: myapp: hidden symbol `void std::__ostream_fill<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, long)' isn't defined
/usr/bin/ld: final link failed: Nonrepresentable section on output

In RHEL5.3, I am using /usr/bin/g++43 for compilation and linking. The correct libstdc++.so is found here:

/usr/lib/gcc/i386-redhat-linux6E/4.3.2/libstdc++.so

which is a text file containing INPUT ( -lstdc++_nonshared /usr/lib/libstdc++.so.6 ).

Wouldn't that mismatch the system stdlibc++ 4.1 version?

Answer 1

You seem to be running into visibility issues -- can we see your full command line?

For example, what -fvisibility-inlines-hidden does may change at different optimization levels because GCC decides to inline different things.

Answer 2

It only happens with optimization. Does that give a clue?

Answer 3

It turns out to be a GCC bug in RHEL 5.3 :-/. https://bugzilla.redhat.com/show_bug.cgi?id=493929. I sent an email to the maintainer, Jakub Jelinek, who said that RHEL 5.4 (which is due out soon) will have a fix and also will bump to GCC 4.4.

A workaround is to use -fno-inline, but this has some obvious drawbacks.
