[Bsd-sharp-list] Mono on FreeBSD/arm

[Björn König]

Hello,

currently I'm trying to use Mono on FreeBSD/arm after a few difficulties
to compile "mono" and many cups of coffee I finally got a working binary.

If you like to have a look at the current state of my efforts then try the
patch that I attached to this mail. It has to be applied to the FreeBSD's
lang/mono port in order to start compiling Mono on FreeBSD/arm. I use
7-current but most likely it works with 6 too.

The port produces a mono binary in work/mono-1.2.3.1/mono/mini/. With this
binary you can already execute programs. I tested it with some simple
"hello world" programs.

I'm not able to compile mcs.exe, because of FPU-related issues. Actually
the problem is that my CPU (ARM9TDMI) doesn't have an FPU and the
compilation of mcs fails with this message:

[...]

I would appreciate if somebody is able to spend some time to make it
possible to compile mcs without having an FPU, i.e. with softfloat.

Regards
Björn
