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: ... CMakeFiles/bin/openlierox.dir/src/common/IpToCountryDB.o: In function `stlpd_std::basic_filebuf<char, stlpd_std::char_traits<char> >::_M_exit_input_mode()': /usr/include/stlport/stl/_fstream.c:120: undefined reference to `stlpd_std::_Filebuf_base::_M_unmap(void*, long)' CMakeFiles/bin/openlierox.dir/src/common/FindFile.o: In function `stlpd_std::basic_filebuf<char, stlpd_std::char_traits<char> >::showmanyc()': /usr/include/stlport/stl/_fstream.c:137: undefined reference to `stlpd_std::_Filebuf_base::_M_seek(long, int)' CMakeFiles/bin/openlierox.dir/src/common/FindFile.o: In function `stlpd_std::basic_filebuf<char, stlpd_std::char_traits<char> >::seekpos(stlpd_std::fpos<__mbstate_t>, int)': /usr/include/stlport/stl/_fstream.c:377: undefined reference to `stlpd_std::_Filebuf_base::_M_seek(long, int)' CMakeFiles/bin/openlierox.dir/src/common/FindFile.o: In function `stlpd_std::basic_filebuf<char, stlpd_std::char_traits<char> >::seekoff(long, int, int)': /usr/include/stlport/stl/_fstream.c:291: undefined reference to `stlpd_std::_Filebuf_base::_M_seek(long, int)' /usr/include/stlport/stl/_fstream.c:297: undefined reference to `stlpd_std::_Filebuf_base::_M_seek(long, int)' /usr/include/stlport/stl/_fstream.c:305: undefined reference to `stlpd_std::_Filebuf_base::_M_seek(long, int)' CMakeFiles/bin/openlierox.dir/src/common/FindFile.o:/usr/include/stlport/stl/_fstream.c:305: more undefined references to `stlpd_std::_Filebuf_base::_M_seek(long, int)' follow ... 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.
