What is the best way to go from this:
Makefile:
The easy way to convert a Makefile to a shell script is "make -n". That
will print out all of the commands that make would run. From there it's a
Mere Matter of Programming to have perl (or whatever) edit that down into
your JCL scripts.
Hi Richard. Thanks for your reply.
1. That would include a lot of irrelevant commands - compiles and
links of the generator files interspersed with what I actually need
to go into the stage 1 executable on the target machine.
Maybe a variable STAGE1_OBJS would be suitable?
2. If the normal way to do things is to parse the make -n output
with perl etc, that's fine, I'll do it that way. I was just wondering
if the proper way was to incorporate the logic into a Makefile
rule and get that rule repeatedly executed rather than just
having a simple "echo". It seems to me that having a generic
rule to execute an external script would be neater???
BTW, I remember your name from the i370 md. Why were you
interested in i370 at the time (probably many years ago)? Or
was someone else just asking a public question and you
answered it (like now)?
BFN. Paul.
