support gfortran about osxcross

[tpoechtrager]

do you support gfortran cross compiles

No, Java and Fortran are not really a goal of OSXCross.

However, you can adjust build_gcc.sh to gain Fortran/Java support:

--enable-languages=c,c++,objc,obj-c++,fortran,java \
--with-ecj-jar=/usr/share/java/eclipse-ecj.jar \
--enable-libjava-multilib \
--enable-static-libjava \

Building libjava fails, similar to:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=42311.

You may be able to get around it by setting GCC_FOR_ECJX before configuring.

Fortran seems to work.

is it possible to setup a minimal cross compile environment that only provides java/veclib?

Well, this is a little bit complicated, you'll always need clang to build cctools/ld64 (ld64 won't build with gcc) and the Mac OS X SDK to build gcc itself (and afterwards for linking, libc, ...).

ok, thanks.

btw, I'm not asking for java support in gcc, only fortran and c. It's the java .so that I'm linking to (i.e. jni), not the gnu java crap.

Yes, gcc and gfortran are working, just adjust the languages to "c,c++,fortran" in build_gcc.sh.
You can get rid of c++ too, but be sure to remove the g++ tests first, look for test_compiler in build_gcc.sh.

sweet, I might give it a shot.
