cross-compile alien

[Martin <wtxnh-lua@...>]

Hi,

I have tryed to cross-compile alien on Debian for Windows system with
i586-mingw32msvc-gcc cross-compiler.
I have done it as follows:

$ cd alien-0.4.1
$ cd libffi
$ ./configure --disable-shared -host=i586-mingw32msvc CFLAGS=-DX86_WIN32
$ make
$ cd ..
$ i586-mingw32msvc-gcc -shared -s  -I../installed/include -Ilibffi/include -DWINDOWS -L../installed -llua51 -o src/alien/core.dll src/alien/core.c libffi/.libs/libffi.a
$ i586-mingw32msvc-gcc -shared -s  -I../installed/include -Ilibffi/include -DWINDOWS -L../installed -llua51 -o src/alien/struct.dll src/alien/struct.c

It all compiles with only warnings like:
src/alien/core.c:715: warning: assignment makes pointer from integer without a cast

Then I copyed files
src/alien.lua
src/alien/core.dll
src/alien/struct.dll
to appropriate places in '../installed' directory.

Now I can test it with:
$ cd ../installed
$ wine lua ../alien-0.4.1/samples/libc.lua
lua: Procedure not found

stack traceback:
	[C]: ?
	../alien-0.4.1/samples/libc.lua:6: in main chunk
	[C]: ?


As it seems it is not able to execute line 6:
libc.malloc:types("pointer", "int")

Something here is apparently not as it should be. My  wild guess is
that libffi is not compiled properly mainly because there is directory
alien-0.4.1/libffi/win32
but it is not used when I compile it with configure and make as showed
above.

Anybody has a clue what is really wrong here and how do I need to
cross-compile it?
