Re: [Boost-users] Link error with boost regex and STLport

Hello John

> Why not?  Did you build regex against STLport?

It isn't that important to me to solve this isse, since at work (I'm a
student helper) I'm using mingw wich works fine with matlab libstdc++
and boost regex. But maybe there are others who need to handle this, so
for investigation...

... I compiled boost-1.33.1 by typing:

bjam -sTOOLS="gcc-stlport" -sSTLPORT_PATH="/usr/include/stlport/"
-sSTLPORT_VERSION="5.0.2" -sBUILD="release <runtime-link>dynamic
<stlport-iostream>on" stage

and adding a symbolic link

        ln -s libstlport.so libstlport_gcc.so

in /usr/lib since boost links with -lstlport_gcc.

I'm using cmake where this is the CMakeList.txt file being relevant:
<CMakeList.txt>
        set(incl_dirs ${incl_dirs} /usr/include/stlport )
        set( incl_dirs ${incl_dirs} ../utils )	
        include_directories( ${incl_dirs} )

        set(lib_dirs ${lib_dirs}
                /home/maik/Eigene-Dateien/WZL/boost_1_33_1/bin/boost/libs/regex/build/libboost_regex.so/gcc-stlport/release/shared-linkable-true )		
        link_directories( ${lib_dirs} )

        add_definitions(-D_REENTRANT )

add_executable(find_regex find_regex.cc)
        target_link_libraries(find_regex
                boost_regex-gcc-p-1_33_1 
                stlport
        )

If you want me to, I can try with boost-cvs.
