Hi,
Anybody compiled rtai in buildroot-2016.02 version ?
Other than "rtai_math.ko" all the modules compiles without error. When I
include math module for compilation, I am getting the following error,
The part of the make error log I attached with that.
Help me to resolve the issue.

Unfortunately RTAI is a kernel extension so it doesn't get tested by the
autobuilders...

^^^^^
It is using headers from the host, which is very wrong.
Perhaps we should remove RTAI. The most recent patch for x86 is 3.8, and the
most recent patch for ppc is 2.6.29... Oh, and there is a new version 5.0-test2
released in May that goes up to 4.1 for x86 (and drops ppc).
Regards,
Arnout

So x86 is the only supported arch? I see that test2 isn't even announced
on rtai.org :/
I personally don't have any issues removing RTAI if it doesn't get
updated / nobody uses it.
If you DO use it, please speak up.

Hi,
RTAI supports to ARM ,m68, PPC and x86.
I am using it in my project.
Recently I compiled RTAI-4.0.1 with 3.8.13 kernel. It is working fine.
I found some changes and modifications are required for building
rtai_math.ko module.
I did the changes in generated makefile after that it started building. (I
followed http://mail.rtai.org/pipermail/rtai/2012-December/025250.html )
Rtai releases are not as fast as Linux Kernel and buildroot.Don't remove
the RTAI module from buildroot.

I guess for x86 then? Because I don't see a usable patch for 3.8 ARM or
PowerPC, as I wrote below.

It doesn't make sense to keep RTAI if it is not possible to actually use it.
Your problem shows that it is not usable at the moment. So unless you or someone
else are willing to send patches to fix the issues with it, it makes no sense
for us to keep it around. People who do need it can always recover it from git
history and try to fix the failures.

Arnout
