You should try the -d2 option to see if the libraries you want to link against are actually used and the proper link option (auto-import) is used. Do the other tools link against the dll or the import library i.e. lib.a?

Hi all,

I have a smalle shared library which I can't compile with bjam.
My Jamfile looks like this:

import os ;
local
WXWIDGETS = [ os.environ WXWIDGETS ] ;

lib wxbase292u_gcc_custom : : <file>$(WXWIDGETS)
/lib/gcc_dll/wxbase292u_gcc_custom.dll ;
lib wxmsw292u_adv_gcc_custom : : <file>$(WXWIDGETS)
/lib/gcc_dll/wxmsw292u_adv_gcc_custom.dll ;
lib wxmsw292u_core_gcc_custom : : <file>$(WXWIDGETS)
/lib/gcc_dll/wxmsw292u_core_gcc_custom.dll ;

#explicit wxbase292u_gcc_custom ;
#explicit wxmsw292u_adv_gcc_custom ;

#explicit wxmsw292u_core_gcc_custom ;

lib configFile : [ glob src/*.cpp : .git ]

wxbase292u_gcc_custom/<link>shared
                 wxmsw292u_adv_gcc_custom/<link>shared
                 wxmsw292u_core_gcc_custom/<link>shared

               : <include>$(WXWIDGETS)/include
                 <include>$(WXWIDGETS)/lib/gcc_dll/mswu
               : <link>shared

                 <linkflags>"-Wl,--enable-auto-import"
                 <variant>"release"
                <define>"__WXMSW__" ;

I'm trying
to compile on windows xp and it doesn't matter if I'm using bjam as downloaded binary or
if I'm compiling bjam by
myself.
My compiler is gcc 4.4.0 MingW.

I don't have any problems with the libraries which doesn't depend on wxwidgets
libraries.
The error messages looks like this:

Thats only a short part of the complete output.

Can somebody help me? I tried everything I found on the
internet, but nothing worked.

BTW, I can compile the project without any problem with eclipse/cdt and the same
libraries.
I also compiled the wxwidgets libraries with the same mingw version! But with the makefile.gcc ...

Thanks
for any help.

Michael
