Re: Problem regenerating file removed by rule [solved]

[Darren Hiebert (Contractor)]

I have solved my problem. The problem was that I made
sub/Makefile.SH an order-only prerequisite of sub/config.sh, which
circumvented the execution of the command for sub/config.sh when its
dependency (sub/Makefile.SH) was out of date. By simply removing the
'|' and making it a normal prerequisite, everything now works as
expected.

Thank you for your help.
