Hi
After some research about compilation error with uclibc relative to
shm_open, I finally found a patch for my toolchain :
http://lists.uclibc.org/pipermail/uclibc/2009-February/041886.html
This patch add missing file for uclibc 0.9.30.1...
This patch fix shm_open issue with 2.1.0 and 2.3.0 version of LTT.
Now just need to test if my work around in getcpu.h allow the tool to
work correctly. So like often, just need to use the good key word in
google to find a way out hehe.
Arthur.
