Hi Chris,

thank you very much for your answer.
The -d2 option doesn't show me some news, so I rechecked, if the 
eclipse ide compiles against the import-libs or the .a as you suggested.
Neither does work, so the eclipse ide links 
against the *.dll.

But now it works, the <cxxflags> was missing and
I changed the <file> to the "<name> & <search>" 
without the .dll file extension.

The last one I did some more times before, so I think the solution is the
<cxxflags>.

Thanks for your help and maybe it helps others, if I publish the end version of my jamfile.

import os ;

local 
WXWIDGETS = [ os.environ WXWIDGETS ] ;

lib wxbase292u_gcc_custom : : <name>wxbase292u_gcc_custom <search>$(WXWIDGETS)
/lib/gcc_dll ;
lib wxmsw292u_adv_gcc_custom : : <name>wxmsw292u_adv_gcc_custom <search>$(WXWIDGETS)/lib/gcc_dll ;
lib 
wxmsw292u_core_gcc_custom : : <name>wxmsw292u_core_gcc_custom <search>$(WXWIDGETS)/lib/gcc_dll ;

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
                 <cxxflags>"-Wall -c -fmessage-length=0"
                 <linkflags>"
-Wl,--enable-auto-import"			   
                 <variant>"release" 
                 <define>"__WXMSW__" ;

Thank you again.

Michael

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
