as I had to learn during my first experiments with RTAI - gcc 2.95.3 is
still the official recommended compiler for kernel code. Some versions of
gcc 3.xx (actually most of them) are known to work well with kernel code
and therefore with RTAI kernel modules. I did do some experiments with 3.x
compilers and it worked well (I had a short look, but short-term I
couldn't find the exact version). Nevertheless I go with 2.95.3. Others
might think different on this - but I do not need features of newer
versions in bare kernel code. It's better to know that the compiler is
prooven to work well in many circumstances for me.
For all my lxrt-userspace stuff (which is most of my work) I use 3.3.3
SuSE compilers though.

Hi, this is perhaps an explanation why I didn't succeed in getting the
rtai to run on a PC with suse. I moved to older rtai versions with older
kernel versions to get everything running on a different Pc, which didn't
give any problems, so I could test some different stuff.
Does the gcc 3.x downloaded from gnu.org also give problems?
I also want to ask if somebody has experience with getting rtai to run
patched 2.4 or 2.6 kernel on a ts 5400 pentium board by technologic
This board or another type of their cheapo boards (www.embeddedx86.com).
