Greeting Hello,all. I compiled oskit-mach as Mr.Marcus wrote. and I tried to make oskit-mach. like following. (in oskit directry) 1:./configure --prefix=/usr 2:make & make install ---THEN Oskit-libraries are installed in /lib (in oskit-mach directry) 1:./configure 2:make & make install and I booted it By using GRUB as root=(hd0,4) #hd0s5 is for hurd kernel=/boot/oskit-mach root=hd0s5 -s module=/boot/serverboot.gz then, following message appeared and froze.

But I can not distinguish which is correct: 1: oskit-compiling itself is failed/ 2: oskit-mach-compiling is failed I'll be glad if you could tell me some advice.... Thanks H.Higuchi<[EMAIL PROTECTED]>
