Ensure that directory is created before its written to This can cause a build race in a highly parallelised build where a directory is not yet created but output file is being written using redirection e.g. rst2man.py --strict --no-raw --no-generator --no-datestamp < ../git/monitor/iwmon.rst > monitor/iwmon.1 /bin/sh: monitor/iwmon.1: No such file or directory make[1]: *** [Makefile:3544: monitor/iwmon.1] Error 1 Signed-off-by: Khem Raj <raj.khem(a)gmail.com&gt; --- v2: create directory before emitting doc files into it v3: No change, rebased on master Makefile.am | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/Makefile.am b/Makefile.am index 9d378d3d..ac83376e 100644 --- a/Makefile.am +++ b/Makefile.am @@ -631,8 +631,9 @@ SED_PROCESS = $(AM_V_GEN)$(MKDIR_P) $(dir $@) && $(SED) \ < $< > $@ if RUN_RST2MAN -RST2MAN_PROCESS = $(AM_V_GEN)$(RST2MAN) --strict --no-raw --no-generator \ - --no-datestamp $< $@ +RST2MAN_PROCESS = $(AM_V_GEN)$(MKDIR_P) $(dir $@) && \ + $(AM_V_GEN)$(RST2MAN) --strict --no-raw \ + --no-generator --no-datestamp $< $@ else RST2MAN_PROCESS = $(AM_V_GEN)test -f $@ || \ { echo "Generated manual page $@ does not exist"; false; } -- 2.25.1
