Make will 'expand' all variables at initialization so we cannot rely on
checking subdir/lib.o since it might not have been build yet. Instead
use 'test && echo' on the ld command line.
Makes it more obvious which files are actually installed. MKINSTALLDIRS
still spurs out a lot of 'mkdir ...', which probably should also be
silenced when V=0.
... so it is easier to figure out where in the tree it's at:
...
[LD] /src/cookies/lib.o
[MAKE all] /src/dialogs
[CC] /src/dialogs/document.c
...
[LINK] /src/elinks
...
which means the user will also get a hint at where the elinks binary
is.
Yeah, yeah, useless bloat, I know. But I have to figure out some way to
get the whole tree build time above 1 minute. ;-)
It is a little ugly since I couldn't get $(wildcard) to expand *.o files
so it just checks if there are any *.c files and then link in the lib.o
based on that.
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
- Fix the doc/ clean target which was called clean-local
- Consistently use $(RM)
- Introduce CLEAN variable to make it simpler to costumize local cleaning
All objects defining $(OBJS) will get them and *.a deleted during
make clean.
The all, clean and install rules now implicitly imply their -recursive
counterparts - those will just do nothing in case of $(SUBDIRS) not
defined, so that's ok.
The root makefile is converted as well as some leaf Makefiles. This
also brings in the required infrastructure and adjusts configure.in
appropriately.
I converted only makefiles containing no configurable stuff, since
that'll require more consideration yet.
