[uClinux-dev] Error building python in latest uClinux-dist (20120620)

[Luis Alves]

Hi,

I'm getting this error when trying to build python in the latest uClinux-dist:

[...]

Target is 68000 (nommu - no fork).

Any suggestion?


Thanks,
Luis

I don't know that the python sources in the uClinux-dist have ever
been run on a non-MMU system. Sure doesn't look like it from that
error message.

Regards
Greg

As you probably know nommu hasn't got fork system call.

Out of curiosity, why do you need python? Perhaps you could try a
lighter language... like Lua?

Hope this helps,
Ezequiel.
