From 1fd450f99272791df8ea8e1b0f5657678e118e90 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 26 Nov 2019 12:10:45 -0300 Subject: libbpf: Fix up generation of bpf_helper_defs.h $ make -C tools/perf build-test does, ends up with these two problems: make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'. Stop. make[3]: *** Waiting for unfinished jobs.... make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2 make[2]: *** Waiting for unfinished jobs.... Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory and we need '/tools/ after that variable, and after fixing this then we get to another problem: /bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127 make[3]: *** Deleting file 'bpf_helper_defs.h' LD /tmp/build/perf/libapi-in.o make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2 make[2]: *** Waiting for unfinished jobs.... Because this requires something outside the tools/ directories that gets collected into perf's detached tarballs, to fix it just add it to tools/perf/MANIFEST, which this patch does, now it works for that case and also for all these other cases.
