building with $srctree != $objtree, perf-tar-* targets fail to read the MANIFEST file and add the PERF-VERSION-FILE needed by out-of-tree builds. The build errors and an incorrect tar is created: $ make O=build-x86 perf-targz-src-pkg TAR cat: ../tools/perf/MANIFEST: No such file or directory tar: perf-4.1.0-rc8/PERF-VERSION-FILE: Cannot stat: No such file or dir.. tar: Exiting with failure status due to previous errors Kbuild sets objtree to "." and srctree to ".." The command to output MANIFEST becomes: $(cd ..; echo $(cat ../tools/perf/MANIFEST)) Without MANIFEST, the entire kernel source tree is added to the perf source tarball. The *correct* fix is to keep the cd and remove srctree from cat command line since MANIFEST has wildcards that fail to expand working directory isn't srctree. Second, PERF-VERSION-FILE gets not added, because in-tree build path is hardcoded to Makefile: util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null) The PERF-VERSION-GEN needs to be run from tools/perf directory, and the output directory needs to be changed from relative to to absolute. This can be achieved using the $(CURDIR) variable. Also remove the error redirect to /dev/null which hid the error.
