    Question Linking to STL Port Libraries failing

    After hours of googling and options testing I've broken down and decided to ask for help.

    I am trying to compile a test application for the STLPort libraries under MinGW and Msys.

    I successfully compiled STLPort with
    Code:
    ./configure --without-stlport --enable-static --use-static-gcc
    CFLAGS / CXXFLAGS (set to same thing)
    Code:
    $ echo $CFLAGS 
    -I/e/MinGW/include -I/e/Build/STLport-5.2.1/stlport -L/e/MinGW/lib -L/e/MinGW/lib/gcc/mingw32/4.5.0/
    I have made a basic main.cpp to test / try it out
    Code:
    #include <iostream>
    
    using namespace std;
    
    int main (int argc, char * argv[])
    {
      cout << "Hello World!" << endl;
    }
    and am compiling with the command
    Code:
    g++ -Wall -mthreads -I/usr/include/ -L/usr/local/lib/STLPort/ main.cpp -o main.exe -lstlport
    And an ls of the two directories
    Code:
    $ ls /usr/include
    algorithm  climits  cstdio   errno.h      hash_set    iso646.h   locale.h  ostream        setjmp.h   stdio.h        strstream      using

    Code:
    $ ls /usr/local/lib/STLPort/
    allocators.o  collate.o       ctype.o          fstream.o   libstlport.5.2.dll    locale_impl.o  num_get_float.o  ostream.o          string.o
    bitset.o      complex.o       cxa.o            ios.o       libstlport.5.2.dll.a  messages.o     num_put.o        sstream.o          strstream.o
    c_locale.o    complex_io.o    dll_main.o       iostream.o  locale.o              monetary.o     num_put_float.o  stdio_streambuf.o  time_facets.o
    codecvt.o     complex_trig.o  facets_byname.o  istream.o   locale_catalog.o      num_get.o      numpunct.o       stlport.res
    when compiling I get the following output
    Code:
    [DIR_TO_TEMP_OMMITED]\ccP5OPug.o:main.cpp:(.text+0xf): undefined reference to `_imp___ZN8stlp_std4coutE'
    [DIR_TO_TEMP_OMMITED]\ccP5OPug.o:main.cpp:(.text$_ZN8stlp_std8ios_base23_M_check_exception_maskEv[stlp_std::ios_base::_M_check_exception_mask()]+0x1f): undefined reference to `_imp___ZN8stlp_std8ios_base16_M_throw_failureEv'
    collect2: ld returned 1 exit status
    It seems to me like its not finding the 'included' library. What am I doing wrong here? I can compile w/o the STLPort libraries however MinGW (still) doesn't support unicode streams. I would really like said streams.

    I have no idea.

    But shouldn't you give the compiler a lib file for STLPort?

    Yea, I did that. the
    Code:
    -L/usr/local/lib/STLPort/
    added the path and the
    Code:
    -lstlport
    (now -lstlport.5.2 since new compilations) to link it to the libstlport.5.2.dll.a library. I'm pretty sure that I'm missing something basic here because an object dump of the libstlport.5.2.dll.a exports a header that matches the "undefined reference"

    I've posed the question in the STLPort forums. Feel free to mark this thread as closed.
