[pclasses-devel] stupid 'make' tricks

[stephan b. <st...@s1...>]

Yo!

i'm coding and needed a quick kludge to generate some make deps so i can 
generate some headers only if other code actually uses them. i wanted 
the make code to work both in toc makefiles and non-toc makefiles, so i 
had to find a portable way to clean up the temp deps file. i like the 
solution, shown on the last line:


SS_DEPS = .sigslot.deps
$(SS_DEPS): Makefile $(wildcard *.hpp *.cpp)
	@grep -le '# *include.*sigslot.hpp' *.?pp | \
		sed -e 's/$$/: sigslot.generated.hpp/' \
		> $@
include $(SS_DEPS)
BOGO = $(shell rm $(SS_DEPS))


No more having to clean up deps files, assuming you use a deps generator 
which is fast enough (the one in the toc tree was taken from the linux 
source tree, and is FAST).
