It happens that I was just getting ready to set up a *vast* tree of
recursive Makefiles for my GNU GPL audio application Ogg Frog.
Presently it builds with XCode on OS X, but I need Makefiles for other
UNIX-ey platforms, as well as for the odd Mac coder who just prefers
plain old make.
Can you give me any links to HOWTOs that explain how to de-recursify
recursive Makefiles?
(Ogg Frog's website is http://www.oggfrog.com/free-music-software/ -
but note that there won't be anything to download until it reaches
Alpha, which won't be until late Winter at the earliest.)
It's going to be a while before I have the cash, but my plan is to get
one of those expen$ive Dual Quad-Core Xeon Mac Pros so I can build
binaries for all my supported platforms simultaneously, by running
compilers within a bunch of different operating systems under
Parallels.
A complication is that this requires that I keep all the build
products for each platform separate from each of the others.
Presently I have a folder called "Arch". The various builds make
subfolders within Arch like "mac-os-x" and "win32-x86" and so on.
Eventually I'll have more folders like "linux/fedora-core",
"linux/ubuntu" and so on.
It was a huge PITA to set up, but another advantage is that I can do a
clean for all the platforms just by dragging Arch's contents to the
Trash.
Thanks!
Mike
