Bugzilla Bug 182736

I think this is an upstream bug. I am on a PPC with GCC4.
Here is the linker error I get while compiling an own project:

...

I searched a bit around and found this related bug:
http://www.mail-archive.com/debian-bugs-closed@lists.debian.org/msg100642.html

So I looked up the symbols in the libs and got this:

objdump -CT /usr/lib/libstlpor* | grep _M_unmap
...
00057d94 g    DF .text  00000040  Base       
stlp_std::_Filebuf_base::_M_unmap(void*, long long)
0002e75c g    DF .text  00000040  Base       
stlp_std::_Filebuf_base::_M_unmap(void*, long long)
...

objdump -CT /usr/lib/libstlportstlg.so | grep _M_seek
...
000714f4 g    DF .text  000000ec  Base       
stlpd_std::_Filebuf_base::_M_seek(long long, int)
...

You can see, it's very much the same as the one described in this Debian
mailing list.

I will try a more recent version of STLport later, perhaps this bug is fixed
already.

The bug is also in 5.1.3.

I will try to fix it myself now and make a patch if I have success...

I tested now STLport-5.1.2 on another PC (an Athlon, normal x86 system, also
with GCC4) with the attached little sample and I got the same error as on my
PPC. This looks a bit strange to me because I firstly thought of a PPC issue.

Is this normal? Am I doing something wrong?

This is my test-code:

/*
compile with:
g++ fstream_test.cpp -I/usr/include/stlport -D_PTHREADS -D_STLP_DEBUG
-lstlportstlg -o fstream_test
*/

#include <fstream>
#include <iostream>

using namespace std;

int main() {
        std::ifstream file("fstream_test.cpp", ios::in);
        while(!file.eof())
                cout << (char)file.get();
        file.close();

        return 0;
}

Thanks to stkn@#gentoo.de, which points to -D_FILE_OFFSET_BITS=64. This works
for me.

But nevertheless I am not sure if this is normal.

hmm, I think the problem is that we just define -D_FILE_OFFSET_BITS=64 for the
compilation of the library, but we should rather add it to
stlport/stl/config/host.h to make sure that apps using STLport will use the
same settings as for the compilation.

So, we should at least add this to host.h:
#define _FILE_OFFSET_BITS 64
#define _LARGEFILE_SOURCE
#define _LARGEFILE64_SOURCE

But probably also uncomment:
#define _PTHREADS

And define the following directly in host.h instead of user_config.h:
#define _STLP_NATIVE_INCLUDE_PATH ...

And maybe uncomment this one too:
#define _STLP_USE_PERTHREAD_ALLOC 1

@spb: comments please?

Fixed in CVS. Thanks for reporting.
