Although I only encountered this if I specified `make -j15 clean all`, i.e. *both* "clean" and "all"...

I've seen something like this after upgrading perl (I can't remember the exact error, so it may not be the same problem but I'm pretty sure it involves perl.mak). The problem was a result of the perl library path changing, but I never got around to creating a patch. I thought I remembered someone else posting a patch to address this, but I can't find it so perhaps I'm remembering commit 07981dc (Makefile: rebuild perl scripts when perl paths change, 2013-11-18). ``` ## Michael J Gruber, 2015-10-06 14:24 Subject: Re: [BUG?] parallel make interdepencies Message-ID: <5613D98C.1020103@drmicha.warpmail.net> URL: https://gitlist.dev/e/5613D98C.1020103%40drmicha.warpmail.net In-Reply-To: <20151006133341.GS17201@serenity.lan> ``` John Keeping venit, vidit, dixit 06.10.2015 15:33: > On Tue, Oct 06, 2015 at 03:13:05PM +0200, Johannes Schindelin wrote: >> Hi Michael, >> >> On 2015-10-06 10:12, Michael J Gruber wrote: >>> "make -j3" just errored out on me, a follow-up "make" succeeded".

The statistical evidence is 100% clear: It's a John-related issue.

This bug hit me when updating the MSVC-build script in contrib. In a fully cleaned installation there is no PM.stamp file and the perl.mak file fails with a message that can easily be misunderstood. In my case I was doing a `make` dry run, so the rebuilding of the perlscrip list (commit 07981dc) never happened. The wider patch series somehow never made it onto vger (don't know why) but the original is at https://groups.google.com/d/msg/msysgit/aj4v9ZpMIJo/2BA68P0saT0J My fix was (expect whitesapace damage) --- perl/Makefile | 2 ++ 1 file changed, 2 insertions(+) diff --git a/perl/Makefile b/perl/Makefile index 15d96fc..5b86aac 100644 --- a/perl/Makefile +++ b/perl/Makefile @@ -22,7 +22,9 @@ clean: $(RM) $(makfile).old $(RM) PM.stamp +ifneq (,$(wildcard PM.stamp)) $(makfile): PM.stamp +endif ifdef NO_PERL_MAKEMAKER instdir_SQ = $(subst ','\'',$(prefix)/lib) -- 2.4.2.windows.1.5.gd32afb6 -- Philip ```
