At last!!!
I digged a bit in /usr/share/mk/*.mk to see how the makeworld process
was doing to put compiled versions in /usr/obj instead of ${.CURDIR}.
It's all related to the *environment* variable MAKEOBJDIR.
In other words:
anarcat@shall[~/libh/bin/tclh]% make
Warning: Object directory not changed from original /u/anarcat/libh/bin/tclh

Neat, uh?
So I think I will start hacking the build process to adopt a 'make
world'-like method. That is, a "make" in compile/ will call a:
@cd .. && MAKEOBJDIR=3D${.CURDIR}/${UITYPE} make
so that we can scrap the compile/*/Makefiles and use compile/Makefile as
a director. libh/Makefile will then *not* direct the build to compile/
but to bin/ and lib/.
Ideally, we would need a src/ directory. Because the current setup is
nice, if you:
cd libh && make
you get what's expected: a regular build.=20
On the other hand, if I make the MAKEOBJDIR modifs, "cd libh && make"
will do a build in each bin/ and lib/ subdirectories, *not* storing the
binaries in compile/ but in the individual directories. There could be a
special target (all/world) that would DTRT, however.
Putting the source (bin & lib) in a seperate directory will allow the
libh/Makefile to DTRT, that is, call make with the MAKEOBJDIR env in
src/.
This has the advantage that some gross hacks in compile/Makefile.inc can
now be removed. The compiled directories now do not depend on
compile/Makefile.inc, but on the individual lib and bin Makefiles.
I will put that into code and send a patch here for review, since this
is rather unusual.
And I really think moving everything to src/ would not be a bad idea.
That would involve repo-surgery, which thing I cannot do.
What do you people think about that?
A.
