Optimal Compilation Desired

Optimal Compilation Desired

Does anyone have a script or command line that will optimally compile
all code in a given directory, i.e. don't compile specs that have bodies
or separates.  I have a library of reuse code that does not contain any
kind of main and I just want to compile everything.  I currently compile
*.ads and then *.adb, but this of course attempts to compile specs
that don't need to be compiled.

Uhhh, what compiler are we talking about here? With Gnat, you don't compile
specs; they get compiled with every body that withs them. With Tucker's
favorite front-end (used on ObjectAda and GreenHills and probably others),
you should be able to "adareg -all", then use whatever recompilation command
exists for your compiler.

I'm confused about just what you want, but perhaps it just needs a
dummy main program that 'with's every spec in the directory?  ie, pipe
a dir *.ads to a file, then edit that into a set of "with xyz;"
followed by "procedure dummy is begin null;end dummy;"

To clarify, according to the gnat documentation, only package bodies
need to be compiled.  When the body is coompiled the spec will also
get coompiled; therefore if I compile the spec and then turn around
and compile the body, then the first compile of the spec was a waste
of time.  However, if you have a package spec that has no body, then
the spec needs to be compiled.  I was hoping to find a simple way of
giving a command that would compile bodies only except when there was
only a spec.  I had tought about the above solution, but I was hoping
there might be a simpler solution that I can use within our build
scripts.

Thanks,
Tony

why don't you use some sort of make-program, which will exactly
compile what must be compiled and nothing more?
