Any suggestions on how to get around this problem?
I assume when you say "It apparently opens the file for writing" you
mean that makedepend opens the output file (either Makefile, makefile or
whatever is specified with -f) for writing. That would make sense
since it has to write to it, and it would create a problem if you try to
run multiple makedepends. Looking at the source code of makedepend
reveals that it opens the output file once and keeps it open while it
processes the files.
So your options are:
1. Modify makedepend so that it opens and closes the Makefile only when
it needs to write out and behaves nicely if someone else has the
Makefile locked.
2. Specify multiple makedepend processes each with a different Makefile
output (use -f for that) so that there's no contention and then include
each of the different Makefiles thus generated.
