make[1]: *** [GCC/copy_avx512.o] Error 1
Interesting error. I have seen it only when compiling with GCC < 4.9.
The 4.1 branch compiles because it does not feature AVX512. 4.2 is the first version supporting AVX512. I tried to install Ubuntu 12.04 for testing but the package repositories do not contain all required packages to install gcc 5.
If you don't need AVX512, just do a find <LIKWID_SRC_FOLDER>/bench/x86-64 -name "*avx512*" -exec rm {} \; This deletes all avx512 kernels and the build should work.
I am sticking with the 4.1 branch for now. Thanks,
Andy

it did work for me but after doing the make distclean (for the latest stable version that is now).
