Dear All,

    I am able to successfully build the linux kernal with RTAI-4.0, While
building i noticed the following,

 1. when we enable the "compiler cache" in Build options I am getting the
above error, after disabling the compiler cache and re-configuring the RTAI
build succeed.

2.  My host system is "i686" but i am building linux for "i486", whenever i
executed the "make linux-menuconfig", buildroot only builds the
linux-kernel modules, it is not building the rtai modules, while testing
the new build system and rtai, kernel reports the "unknown symbols in rtai
modules".

3.  Is there any provision in buildroot, to automatically build the RTAI
modules whenever "make linux-menuconfig" executed ?


Thanks for the buildroot community and supporters helped me to build the
minimal embedded system.


Thanks & Regards,

B.Thiyagarajan
