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 toolchains, but may not necessarily be the case with uClibc toolchains, since the thread implementation is configurable). https://wiki.linuxfoundation.org/realtime/documentation/howto/tools/rt-tests comment "rt-tests may not work on MIPS with an external uClibc toolchain" depends on BR2_PACKAGE_RT_TESTS depends on BR2_TOOLCHAIN_EXTERNAL_UCLIBC depends on BR2_mips || BR2_mipsel || BR2_mips64 || BR2_mips64el comment "rt-tests needs a uClibc or glibc toolchain w/ NPTL, headers >= 3.14, dynamic library" depends on !BR2_TOOLCHAIN_HAS_THREADS_NPTL || BR2_STATIC_LIBS \ || BR2_TOOLCHAIN_USES_MUSL || !BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_14 depends on BR2_USE_MMU depends on BR2_PACKAGE_NUMACTL_ARCH_SUPPORTS
