[LITMUS^RT] Litmus on single-board computer

Sat Jan 13 15:03:36 CET 2018

Hello Björn, 
I tried to cross-compile liblitmus by setting  LITMUS_KERNEL = ../linux-stable, ARCH = arm64 and CROSS_COMPILE = aarch64-linux-gnu- in the .config file and got the following output.  

~/playground/liblitmus$ make
cp ../linux-stable/include/litmus/rt_param.h include/litmus/rt_param.h
cp ../linux-stable/include/litmus/ctrlpage.h include/litmus/ctrlpage.h
cp ../linux-stable/include/litmus/fpmath.h include/litmus/fpmath.h

Can you help me to figure out what the problem is?

No, it should work just fine. You can either compile locally or cross-compile both like the Linux kernel (i.e., by setting the ARCH and CROSS_COMPILE environment variables).
