[Mingw-users] creating OS exe from windows

[Suren A. <sur...@gm...>]

Hi

Is it possible to create a executable from a Java application using
GCJ for Mac OS using MingW (basically from a windows box)

Don't know.

I'd assume it would be possible. However you'd have to create
a Win32 hosted gcc (stock or mingw) crosscompiler for Mac OS.

I assume with Mac OS you mean OSX -- since there already _is_
a gcc on that system why not get that sources, libs and headers
and try to create a crosscompiler with them ?

Instructions as to how that might be achieved could probably
derived from the Wiki - there is an article describing a Win32
hosted crosscompiler for ARM if I recall it correctly (or was
it Linux?).

Note there are two arcticles dealing with crosscompiler in the Wiki.
One is describing how to create a Linux hosted mingw crosscompiler
for Win32 and the other deals with a Win32 hosted crosscompiler.
You are interested in the later.

Best,
Michael

PS: Once you have got this working you may want to add another
article to the Wiki describing how to create a crosscompiler
for Mac OSX ;)

In theory, it's perfectly possible. In practice, it's difficult to set up
a cross-compiler that targets darwin systems (read: a compiler that runs
on a given computer, with Windows in your case, and creates executables
for MacOS X).

I have been trying myself for some time to create a cross-compiler
targetting darwin (with host=linux in my case), and the conclusions I
drew are the following:

  1. you can have a darwin targeted assembler, by downloading Apple
binutils and cctools, hacking them until they compile. It does require a
faire amount of tweaking, but the produced binaries work fine.

  2. i didn't manage to have a darwin-targeted linker: using the same
approach as 1. never succeeded, never succeeded to produce binaries.

  3. the compiler part, however, should not be difficult once 2. is
resolved.

Good luck!
