After saving the file , when I start compiling the kernel, after 60 minutes
of compilation I get following error.
Note : I have also tried by only changing kernel options from point 1 to
point 12 in xenomai-stable (Before xenomai 3.0.2 was released) but I get
the same error.
Also I dont get any error of such error when I tried it on kernel 3.18.20.
Please guide me in this regard, Following is the Error :
