Most binary distributions created for the Windows platform are built using Microsoft Visual C++. This does not mean that you have to develop or build extensions using this compiler (unless they are exporting C++ symbols!). All you need is a suitable link library and then your mingw32 built application can use the same DLLs as everyone else. For information about the native windows version of the GNU C compiler go to http://www.mingw.org/ .
To build a useful mingw32 gcc link library from the Tcl dlls we can either work from the DLL or the .LIB files provided. We need to get hold of a copy of sed for win32 from somewhere like http://www.wzw.tu-muenchen.de/~syring/win32/UnxUtils.html and either use the nm provided with mingw32 gcc or get dumpbin from a Microsoft download site.
Peter Lewerin (2001-10-25): I have used the sed from the DJGPP package for MS-DOS under Windows. Go to http://www.delorie.com/djgpp/zip-picker.html , select an ftp server, and look for the file pub/simtelnet/gnu/djgpp/v2gnu/sed3028b.zip on that server. You will probably need a minimal install of DJGPP to make it work.
Working from a DLL
Placing Makefile in your tcl lib directory (...\Tcl\lib) should do what is needed. You need dumpbin and sed in your path plus the exports.sed script given below. Unfortunately dumpbin is obly provided with Microsoft compilers so...
It turns out that you can use mingw32 supplied objdump -p to get the export symbols from a DLL. You can use the dllextract.sed script below with objdump - see the makefile. - PT
Working from a .LIB file
.LIB files are the normal Microsoft compiler link libraries. Edit the Makefile by uncommenting the *.def sections and commenting the alternative .def sections. The dlltool section remains the same.
