I'm having a really hard time what order-only prerequsites really do.
First, I thought that they will do just fine if I want to have my object
files go in a separate folder. This makes it necessary to ensure this folder
(let's name it IntemediateFolder) exists before compilation of each source
file. Of course, this check should not render the target (object file)
out-of-date. As far as I get it all this make the folder-existence check
(and creation if necessary) appropriate for an order-only prerequiste.
However, I must be awfully wrong, 'cause I could not come up with a makefile
that does exactly this. And I've been trying it since for a whole day...
So, I've attached the troublesome makefile. I execute it with make 3.80 on a
linux system. Could you explain to me why the script compiles the soruce
files even when the objects do exist and are newer than the corresponding
source files?
Best wishes,
An unsuccessful rocket sceintist
