[Bug libstdc++/22185] New: final link failed: Nonrepresentable section on output

[pedro dot lamarao at mndfck dot org]

I get the following with the net_error.ii file attached to this bug:

[pedro@localhost Projetos]$ g++ -O3 -fPIC -c -o net_error.o net_error.ii
[pedro@localhost Projetos]$ g++ -fPIC -shared -o net_error.so net_error.o
/usr/bin/ld: net_error.o(.text+0x8e): unresolvable relocation against symbol
`std::basic_string<char, std::char_traits<char>, std::allocator<char>
>::_Rep::_S_empty_rep_storage@@GLIBCXX_3.4'
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status

[pedro@localhost Projetos]$ g++ -O3 -c -o net_error.o net_error.ii
[pedro@localhost Projetos]$ g++ -shared -o net_error.so net_error.o
[pedro@localhost Projetos]$

Works fine.

[pedro@localhost Projetos]$ g++ -fPIC -c -o net_error.o net_error.ii
[pedro@localhost Projetos]$ g++ -fPIC -shared -o net_error.so net_error.o
[pedro@localhost Projetos]$

Works fine.

[pedro@localhost Projetos]$ g++ -v

I think this is a binutils bug and not a bug in GCC and/or libstdc++.

Works in the same system with a g++ 3.4.4 compiled from source:

net_error.o net_error.ii

net_error.so net_error.o

It is a gcc bug and has been fixed in CVS:

The real isssue is you can't use

#pragma GCC visibility push(hidden)

on libstdc++ and glibc since they don't support them. We need to fix both glibc
and libstdc++ header files.

One solution is to put

#pragma GCC visibility push(default)
...
#pragma GCC visibility pop

around all libc and libstdc++ header files, like

#pragma GCC visibility push(default)
#include <iostream.h>
#pragma GCC visibility pop

But you may run into bug 20303.

Substituting the pragma for -fvisibility=hidden also seems to solve the problem.
