Hello Serguei,

    Why so complex? I just made makefile, which I include in main one,
http://www.infoservice.lg.ua/~paul/devel/dll_mk.html .

    DJ Delorie is making/have made support for usual 'gcc -shared',
it's in snapshots now and going to be in b21, AFAIU.

    Very easy with mingw32, for cygwin some magic required, it's
almost faq, see maillist archive. (Implib must be rebuilt, yes).

SD> 2) The same questions in the case of C++ code. (I think that I have read

    Of course, there's different mangling, but as egcs guys usually
say, mangling is not the biggest problem with C++.

SD> Well, that's all for the moment.  Here goes the script:

[]

Beware of this, it cripples dlls, at least on win95.


SD> Best regards,

Best regards,
 Paul                            mailto:paul-ml AT is DOT lg DOT ua
