Re: MakeMaker to make Makefile in subdir

[PodMaster]

Its mostly magic. This has been discussed before, but I can't be bothered to super search it, so i'm just gonna give you a few examples of distributions that do this

• libwin32-0.191
• mod_perl

MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

** The third rule of perl club is a statement of fact: pod is sexy.

Great. I checked out libwin32-0.191 and it does seem to magically cascade to Makefile.PL's. But a little experimentation showed the trick is to ensure that each makefile is only one directory below the next. So even though h2xs builds a tree, the next set of modules only want the leaf directory of that tree, and in fact build totally correctly regardless as to what that leaf directory is called. (the latter fact is not shown below. Anyways thanks for the heads up on how to figure this out, I hope its as useful to scain as it has been to me.

Thanks demerphq and PodMaster; this is at least getting me close. There is some magic here. My directory structure looks like this:

   gmod/
       src/
          component1/
          component2/
          component3/

All I had to do was put a simple Makefile.PL in the src/ directory and when the main Makefile.PL was executed in the gmod/ directory, it saw the one in src/, which in turn saw the ones in component directories.

This probably would have worked flawlessly if the items in the component directories were only Perl modules, but they are more complicated than that, and have in their Makefile.PLs custom overrides to the install target (so that items can be installed under /usr/local/apache, for instance). I may be able to get around that by overriding the install target in the main Makefile.PL, but that is unattractive for at least one reason: it makes the main Makefile.PL more fragile (if the author of component1 changes his Makefile.PL and doesn't tell me, it won't work as expected).

Thanks again,
