On a lighter note: my only mips is a philips velo handheld and runs Windows CE at the moment;) I think I'd have to get the Micosoft Visual C++ for Embedded Systems, in order to merge in the KaffeCE port, but I'd like to sort out the situation on Cygwin first, then maybe MingW before I go near Visual C++. I'd like to have everything work on the Win32 platforms for which there already is some support in kaffe or pocketlinux first. There is a linux kernel for my velo, 2.3.99 something from linux-vr, but I am not a kernel hacker, and support for the philips mips chip hasn't been merged into any of the two current linux kernel mips trees yet, as far as I know. > P.S.

Here is a sysdepMethodCall written in MIPS assembler with a few complaints about the "horrible calling convention" : http://www.kaffe.org/cgi-bin/viewcvs.cgi/pocketlinux/XOE_1.0/src/kaffe-all/src/config/mips/common.h?rev=1.1.1.1&content-type=text/vnd.viewcvs-markup best regards, dalibor topic __________________________________________________ Do you Yahoo!?
