[Clam-devel] Re: Windows development files distribution

[David García Garzón]

By the way, the next natural step is applying Giulio Paci's patch for native 
compilation. In fact this refactoring of the sandbox conventions has been 
motivated by an initial try to incorporate Giulio Paci patch without breaking 
crosscompilation. I started to feed some of his changes, but then i realized 
that the procedure on the wiki to crosscompile 3rd party libraries was not 
working and i felt that was prioritary to fix it before going forward as we 
are close to release (now hopefully) and we depend at the moment on 
crosscompiling.

Regretably, while redefining the procedure for 3rd party libraries 
crosscompilation I had to make changes to the build system until i had it 
working again: different library names, libraries that were compiled 
differently, checks that had to be performed differently. The consequence is 
that I'll have to apply the rest of Giulio's changes by hand. Changes done on 
crosscompilation are very similar to the ones proposed by Giulio (pkg-config 
based, ogg checks...) and a lot of unneeded checks were removed, so i hope it 
will be an straightforward procedure.

The side note is, Giulio, we might need you help while integrating to assert 
we are applying you patch correctly and to explain us some of the problems 
you solved. Are you still arround?

David.
