Antwort: Re: unknown symbols using rtai_serial/gcc 3.x and embeddedx86 boards

[Dipl. Ing. (FH) Malte Witt]

Hi Taco,

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.

Regards,

Malte

Hi, this is perhaps an explanation why I didn't succeed in getting the 
latest 
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 
with a 
patched 2.4 or 2.6 kernel on a ts 5400 pentium board by technologic 
systems. 
This board or another type of their cheapo boards (www.embeddedx86.com). 
Thanks,
Taco Walstra
