Hello Sam,
Thanks for replying. Well, it looks like mconf is for ncurses menus, and conf
terminal ones if you one to call it like that.
Yes I'm starting from scratch, what I pasted comes from a just untarred linux
tree, where I was reusing my usual config which is ok for my hardware.
If I do what you sugessted this is what I get:
[EMAIL PROTECTED] scripts/kconfig/mconf init/Kconfig
init/Kconfig:48:warning: choice must have a prompt
init/Kconfig:48:warning: choice value must have a prompt
init/Kconfig:51:warning: defaults for choice values not supported
Segmentation fault

Then if I trace it:

So I don't really know, have tried with other kernel versions with same results.
The thing is that I've compiled this kernel tree several times. I understand
Kconfig files aren faulty cose they alwas come from the same tarred tree, which
is the original I've also re-downloaded form kernel's ftp.
And as far as I can say, my building or anyother part isn't broken, or at least
not on a critical part. As a matter of fact I've been able to compile geda,
pcb, dia, glide, etc, after I noticed this, so don't know, any clues?
Kind Regards,
