During installation, host-python and host-python3 run the freshly built python executable. This is done with a proper LD_LIBRARY_PATH to make sure it picks up the libpython in the build directory. However, the python binary has an RPATH pointing to the $(HOST_DIR)/usr/lib. Therefore, if libpython exists there, it will be used instead. If the install step is run in parallel, it is possible that libpython is already partially copied to $(HOST_DIR)/usr/lib when python is run. This gives an error like: python: error while loading shared libraries: $(HOST_DIR)/usr/lib/libpython3.4m.so.1.0: file too short The fix is simple: use RUNPATH instead of RPATH, which allows LD_LIBRARY_PATH to override RUNPATH. That way, the libpython in the build directory is always used. RUNPATH is enabled by passing --enable-new-dtags to the linker.
