All tools are simple C programs with no dependencies, except the hwlatdetect utility, which is a Python script and therefore requires the Python interpreter. It will only be installed if a Python interpreter has been selected in the Buildroot configuration. Note that this package requires a toolchain built with the NPTL implementation of the pthread API (this is always the case with glibc/eglibc toolchains, but may not necessarily be the case with uClibc toolchains, since the thread implementation is configurable). http://rt.wiki.kernel.org comment "rt-tests needs a toolchain w/ threads" depends on !BR2_PTHREADS && !BR2_PTHREADS_OLD depends on !BR2_avr32 && !BR2_xtensa && !BR2_arc depends on !BR2_TOOLCHAIN_HAS_THREADS
