Bug 415221 – cross-i686-pc-mingw32/gcc-4.5.3-r2 g++ can't link programs with STL

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description M8R-u38wij 2012-05-09 11:05:24 UTC]

Arter installing i686-pc-mingw32 with crossdev I try to compile helloworld.cpp and linkage fails with next error next error:
$ i686-pc-mingw32-g++ -c helloworld.cpp
$ i686-pc-mingw32-g++ helloworld.o
/tmp/ccLGjfxr.o:helloworld.cpp:(.text+0x19): undefined reference to `std::cout'
/tmp/ccLGjfxr.o:helloworld.cpp:(.text+0x1e): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)'

/tmp/ccLGjfxr.o:helloworld.cpp:(.text+0x6a): undefined reference to `std::ios_base::Init::Init()'
collect2: ld returned 1 exit status


Reproducible: Always

Steps to Reproduce:
1.# crossdev --stable --target i686-pc-mingw32
2.$ i686-pc-mingw32-g++ -c helloworld.cpp
3.$ i686-pc-mingw32-g++ helloworld.o
Actual Results:  
Linkage fails, can't find STL objects

Expected Results:  
Linkage success

Installation logs of mingw32 toolchain are attached

(In reply to comment #4)

Works correctly on my x86 PC and produces error on amd64 laptop. On which architecture you run it?

[Comment 7 SpanKY 2012-05-16 05:17:21 UTC]

my amd64 desktop

Works fine after upgrade to gcc-4.6.3

[Comment 9 Sergei Trofimovich (RETIRED) 2012-06-29 20:29:50 UTC]

I had such problems when I had two migw32-g++ installed:
4.5 (active) and 4.7.

For some reason 4.5 had empty libstdc++.

4.6.3 seems to produce binaries, but they are broken.
Even simple <iostream>y "hello world" produced by 4.6.3
dies before main() (somewhere in sjlj.dll loader).

Binaried built winh 4.7.1 look and run fine.
