[Javier Sanz]

Hello,

I am trying to compile rt-tests-0.96 and i got :

root@darkstar rt-tests-0.96]# make
gcc -D VERSION=0.96 -c src/cyclictest/cyclictest.c -Wall -Wno-nonnull
-O2 -DNUMA -D_GNU_SOURCE -Isrc/include -o bld/cyclictest.o
In file included from src/cyclictest/cyclictest.c:39:0:
src/cyclictest/rt_numa.h:29:18: fatal error: numa.h: No such file or directory
compilation terminated.
Makefile:87: recipe for target 'bld/cyclictest.o' failed
make: *** [bld/cyclictest.o] Error 1
[root@darkstar rt-tests-0.96]#

Some documentation on the rt wiki:
    https://rt.wiki.kernel.org/index.php/Cyclictest#Compile_failure_because_numa.h_can.27t_be_found
[which says that the package on Fedora-derived systems is numactl-devel]

On Debian-derived systems, the header is from libnuma-dev.

I think the original thinking was that it is a trivial thing to install 
the numa libs even if you are not going to use them, but I have personally 
liked this. I could imagine that this requirement is not 
always so simple in the embedded space. I'll look into seeing if I can 
remove this. (or try yourself, and send me a patch.)

Thanks

John

Should read, "I have NEVER liked this" :)
