I compiled the libs for GnuPG on several platforms without any
problems. Usually I have the Systems which I compile for at least in a
virtual machine, so there is no need for cross compiling. But it should
work if the environment ist set up correctly, that I am sure of. There
is no program out there which cross compiles without any changes that
have to be made. On my fedora machine there are, for example, some
wrapper scripts if you want to cross compile for mingw which set up the
environment for configure, cmake and various other build systems.

Even my own programs which are completely made with Autotools and
pkg-config need some tweaks if I want to cross compile them for
Windows, for example.

That's the reason why I prefer to compile on the target platform, this
makes life much easier. ^^

Dirk
