Re: rtai testsuite make issue (magma kernel)

Thank you for the responses.

I realized lately that I have not built rtai source (make menuconfig, make,
install in rtai source folder).

Quick summary of steps I followed as per
https://www.rtai.org/userfiles/downloads/RTAILAB/RTAI-TARGET-HOWTO.txt ( I
excluded MESA lib and EFLTK lib installation steps though ie step 7, 8;
executing remaining as is).


   - I have taken
   https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.16.tar.gz
   - I have taken rtai - magma from
   https://github.com/ShabbyX/RTAI/tree/magma
   - Patch  : Tried with hal-linux-3.16-x86-3.patch
   <https://github.com/ShabbyX/RTAI/blob/magma/base/arch/x86/patches/hal-linux-3.16-x86-3.patch>
   and hal-linux-3.16-x86-3.patch
   <https://github.com/ShabbyX/RTAI/blob/magma/base/arch/x86/patches/hal-linux-3.16-x86-3.patch>,
   facing same issue with both of them.
   - After building linux kernel source, making modifications as mentioned
   and rebooting to newly built kernel, Now executing step 9 which builds and
   install rtai source. *Getting error here as:*

- - - -

bhargavb@bhargavb-Latitude-E6500:/usr/src/rtai$

*Note:* I tried in menuconfig by disabling "build rtai test suite" and
saved it, because the error I got is related to testsuite make files
generation, but it does'nt have any effect.(Could not figure out whar is
wrong).

I sincerely request your inputs, as am currently in time critical project
where I need to port my desktop application to real time. I am unable to
setup the rtai environment.

Thanks and regards,

Bhargav
