I tried that. The 'configure' script provided with the binutils of the
LEOX release 1.0.4 infinite loops somehow. This happens when I try to
build the tools on a SUN workstation (running SunOS 5.6). I have tried
setting CC=gcc (instead of the default /usr/ucb/cc) and resetting the
scripts to use bash instead of sh, and things till hang.
I am limping along now because I got the LEOX tools to build on a i586
linux box, but the linux box is not connected to our network, and the file
transfer process to and from my production environment (on the Sun) is very
time consuming and frustrating.
Has anyone else reported LEOX configuration successes problems on Sun
hosts? Any thoughts on what to do? If I get some time extra time on my
hands, I might try resetting my PATH to point to known POSIX compatible
versions of grep, cp, rm, and so forth, but given my current knowledge I am
reluctant to invest more time into the configure problem.
Thank you for your help,
Christian Schreiner

The way to create a ROM file system is as follow:
1) Create a complete file system:
mkdir -p romdisk/bin
mkdir -p romdisk/dev
2) Create device nodes (no need to be root):
touch romdisk/dev/@ttyS0,c,4,64
3) Generate your file system:
/opt/leox/gnu/bin/genromfs -v -V "ROM Disk" -f romdisk.img -d romdisk
Make sure to use the genromfs from the leox-CDK, it is really complete
and up to date.
