Hello,
I tried to build and run oskit-mach today. Building (see below) went
fine, but when I try to boot it, I get the following (transcribed):
Welcome to GNU Mach 1.91!

I get this error on two different machines, a P2-400 and a P-M-1500.
Marco told me that this error is also experienced by several other
people.
I used the following entry in menu.lst:
# For booting GNU/Hurd
title GNU/Hurd (oskit-mach)
root (hd0,13)
kernel /boot/oskit-mach.gz root=device:hd0s14 --
module /hurd/ext2fs.static --multiboot-command-line=${kernel-command-line}
--host-priv-port=${host-port} --device-master-port=${device-port}
--exec-server-task=${exec-task} -T typed ${root} $(task-create) $(task-resume)
module /lib/ld.so.1 /hurd/exec $(exec-task=task-create)
I got the source for oskit from savannah CVS (oskit project), same for
gnumach2 from the hurd project. I did not apply any further patches.
Both builds where done in a build-directory. I configured oskit as
follows:
../configure --prefix=/usr/local --enable-debug
--enable-modulefile=../modules.x86.pc
and did 'make', 'make install'. Then, I configured gnumach2:
CFLAGS="-g -O2" OSKIT_LIBDIR=/usr/local/lib/oskit ../configure
--prefix=/gnu
and did the same.
This is the output of gcc -v:
Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.4/specs

Anybody tried to build oskit-mach recently and could tell me which
compiler/configure options/patches to use? I have attached the oskit
modules file (I also tried another one, with the same result).
