Hi,


first a short disclaimer -- I have no idea if this is the correct
mailing list, but there seems to be no other way of contacting the
fvwm maintainers. If this mail is inapropriate, I'm sorry.

Anyway, I have an addendum to FAQ 4.3 "I'm seeing odd things when
trying to preprocess files with the FvwmM4/Cpp module...".

I was seeing strange things too. On our setup, the main .fvwm2rc file
reads a number of different subfiles, some of which were parsed with
FvwmM4. This periodically led to a race condition where FvwmM4 was not
finished processing before the M4 output was needed elsewhere in the
configuration (in our case, the problem was with FvwmButtons being
started before the apps to swallow had been started). The fix detailed
in FAQ 4.3 did not help (because we were starting other modules), but
the solution was surprisingly simple:

I replaced all "FvmM4 <file>" commands with "PipeRead 'm4 <file>'" and
everything seems to work now.
