I have a makefile which calls some bash scripts and shell commands.
One of those scripts generates a code (say, generated.h) file according to another code file (say source.h) – and I want it to be called only if source.h was updated after generated.h was updated.
(In pseudo code:
if update_time(generated.h) < update_time(source.h)
call GenerateCodeFile.sh
end if
)
How can I do it from within a makefile?
Thanks.
Be aware that that’s a literal
