The util/python-ext-sources file contains source files required to build the python extension relative to $(srctree)/tools/perf, Such a file path $(FILE).c is handed over to the python extension build system, which builds the final object in the $(PYTHON_EXTBUILD)/tmp/$(FILE).o path. After the build is done all files from $(PYTHON_EXTBUILD)lib/ are carried as the result binaries. Above system fails when we add source file relative to ../lib, which we do for: ../lib/bitmap.c ../lib/find_bit.c ../lib/hweight.c ../lib/rbtree.c All above objects will be built like: $(PYTHON_EXTBUILD)/tmp/../lib/bitmap.c $(PYTHON_EXTBUILD)/tmp/../lib/find_bit.c $(PYTHON_EXTBUILD)/tmp/../lib/hweight.c $(PYTHON_EXTBUILD)/tmp/../lib/rbtree.c which accidentally happens to be final library path: $(PYTHON_EXTBUILD)/lib/ Changing setup.py to pass full paths of source files to Extension build class and thus keep all built objects under $(PYTHON_EXTBUILD)tmp directory.
