It seems that cyclictest and switchtest compile fine.
I had no error when I installed Xenomai.
Here is an example of code that fails :

Does this happen when compiling Xenomai posix programs, such as
cyclictest or switchtest ?
As usual, please show us an example of code that fails (including the
Makefile).
