Yup. But it's unclear why we should include the header via the cc command line? From: Alexander Shishkin <alexander.shishkin@xxxxxxxxxxxxxxx> Subject: rbtree-adjust-root-color-in-rb_insert_color-only-when-necessary-fix-perf-compilation Commit 2cfaf9cc68190c24fdd05e4d104099b3f27c7a44 (rbtree: adjust root color in rb_insert_color() only when necessary) introduces bool type and constants to the rbtree.c, and breaks compilation of tools/perf: ../../lib/rbtree.c: In function `rb_insert_color': ../../lib/rbtree.c:95:9: error: `true' undeclared (first use in this function) ../../lib/rbtree.c:95:9: note: each undeclared identifier is reported only once or each function it appears in ../../lib/rbtree.c: In function `__rb_erase_color': ../../lib/rbtree.c:216:9: error: `true' undeclared (first use in this function) ../../lib/rbtree.c: In function `rb_erase': ../../lib/rbtree.c:368:2: error: unknown type name `bool' make: *** [util/rbtree.o] Error 1 This patch is the easiest solution I can think of.
