I tried yesterday as well with JOBS=4 and it worked.  Closing report.

As of yesterday I've tried building without --disable-docs and with JOBS= ( > 1) and it works fine now. Thanks for fixing.

So I think this bug report can be closed. Or do we want confirmation from others?

Is this still a problem?  I modified the rule in scripts/module.mk file to use the .in file instead of the generated .m file.

I was able to successfully build by reducing the number of JOBS to 1 in settings.mk for MXE.  There may be a race condition during the build.

Since the reason for generating the file doesn't have anything to do with the docstring, it should be fine to extract the docstring from the .in file instead of the generated .m file.  I thought I made that change.

We already do the same kind of thing for some other generated files like the lexer and parser sources.

The problem is that DOCSTRINGS contains documentation for the file gnuplot_binary.m while DOCSTRINGS-t does not.  This, in turn, is caused by the fact that the source directory only contains gnuplot_binary.in.  A makefile action turns the .in file into a .m file but the location of the file is now in the build directory.

It would seem that this rule in scripts/module.mk needs to be modified.

$(srcdir)/scripts/DOCSTRINGS: $(FCN_FILES) $(GEN_FCN_FILES) | scripts/$(octave-dirstamp)
        $(AM_V_GEN)rm -f scripts/DOCSTRINGS-t && \
        $(PERL) $(srcdir)/scripts/mkdoc.pl "$(srcdir)" $(FCN_FILES) -- $(GEN_FCN_FILES) > scripts/DOCSTRINGS-t && \
        $(SHELL) $(srcdir)/build-aux/move-if-change scripts/DOCSTRINGS-t $@

The variable GEN_FCN_FILES currently expands to the single file "scripts/plot/util/gnuplot_binary.m".  It needs to expand to "$(builddir)/scripts/plot/util/gnuplot_binary.m".  Or the mkdoc.pl script needs to be modified to take srcdir and builddir arguments.

At any rate, these three changesets look like they might be the proximate cause of this problem.

Confirmed.  Before I get the warning about scripts/DOCSTRINGS-t I have this message:

cmp: EOF on scripts/DOCSTRINGS-t

Building with --disable-docs works fine.
