Qtopia had a large number of .a files and this hit us hard so we devised
a workaround.
# A function to create explicit dependencies in a Makefile
defineTest(create_raw_dependency) {
var=$$1
dep=$$2
eval($${var}.depends*=\$$dep)
export($${var}.depends)
QMAKE_EXTRA_TARGETS*=$$var
export(QMAKE_EXTRA_TARGETS)
}
# relink our binary when foo.a changes
create_raw_dependency($$TARGET, /path/to/foo.a)
This literally gave us a rule in the Makefile like this:
mybin: /path/to/foo.a
Luckily, make doesn't care if you have multiple "rules" for a product,
as long as only one of them executes commands.
I doubt this works on non-Makefile projects though. Possibly not even on
non-GNU make. Probably easier to just have qmake generate the dependency
itself :)
