Re: RTAI-EMC .. bdi??


Hi all

I am currently useing rtai and 2.4.18 on Mandrake 8.2 (Beta) , the
problems I have found are that with 2.96 ( Mandrake inistall ) that you
get several errors on compiling the kernel and rtai refuses to build. To
get around this i have downloaded gcc-2.95.3 from
ftp://ftp.gnu.org/pub/gnu/gcc and installed it . You then make a link in
the /etc/alternatives directory from gcc-2.95.3 to gcc. This soould
change the version of the compiler that is being used . The only problem
is that the compiler dosnt understand K7 and P4 soif you have either of
these set you proccesor type to K6 anr i686.
Paul, have the change to emcmot.c been commited to the cvs yet for the
problem in building freqmot.o in rtai?

Regards, Jason
