Re: [Gnucap-devel] mingw DLL problem

[Holger Vogt]

Al,

what I have just stated (see blelow) does not work for MINGW (but for MS 
http://msdn2.microsoft.com/en-us/library/z4zxe9k8(VS.80).aspx).
Module definition files in MINGW may be used for describing foreign dlls 
(http://www.mingw.org/MinGWiki/index.php/CreateImportLibraries)

another option for creating the dll:

// test_dll.cpp
int bar()
{
return (2);
}

The file now has no #include of an export statement.

You need however, a module definition file TestDLL.def:

LIBRARY TestDLL
DESCRIPTION "Simple DLL"
EXPORTS
        bar

This file is now linked in by the statement in the makefile:

##      $(CC) -shared *.o $(CFLAGS) -o $(DLL) --driver-name=g++ $(LIBDIR)
-Wl,--out-implib,lib$(MODULE).a 2>&1 | c++filt

        $(CC) -shared *.o --def $(MODULE).def $(CFLAGS) -o $(DLL)
--driver-name=g++ $(LIBDIR) -Wl,--out-implib,lib$(MODULE).a 2>&1 | c++filt
