Huh? The test is a simple C binary you shouldn't need anything more than: $ git clone https://github.com/linux-test-project/ltp.git $ cd ltp $ make autotools $ ./configure $ cd testcases/kernel/syscalls/readahead $ make $ ./readahead01 And this is well described in the readme at: https://github.com/linux-test-project/ltp/ And the packages required for the compilation are make, C compiler and autotools nothing extraordinary. -- Cyril Hrubis chrubis@xxxxxxx
