From: Changqing Li <[email protected]> [snip of Makefile] # bison will create both sqlhist.tab.c and sqlhist.tab.h sqlhist.tab.h: sqlhist.tab.c: sqlhist.y sqlhist.tab.h bison --debug -v --report-file=bison.report -d -o $@ $< [snip]
sources of libtracefs is fetched by git, the mtime of sqlhist.y, sqlhist.tab.c is random. so sometimes, sqlhist.tab.c is regenerated, sometimes, sqlhist.tab.c in original sources in used. bison used to gernerate sqlhist.tab.c by upstream libtracefs maybe has different version with the build host one. This make the final libtracefs.so not reproducible. This fix touch sqlhist.tab.c to make it has the newest mtime, and sqlhist.tab.c is not regenerated during build.
