It would be nice to have a module that returns the installed parrot config.
Other applications (hopefully a lot) that configure depending on parrot might
need this. I mean something like App::Info::HTTPD::Apache
(http://search.cpan.org/~dwheeler/App-Info-0.44/).
I am not into App::Info so I can not decide what is neccessary to make it
return parrot specific values ...

Already exists.

perldoc parrot/library/config.imc

Regards.

[William Coleda]

Whoops, had already cd'd...

it's actually in 'runtime/parrot/library/config.imc'

Is this what you're looking for?

[Adrian Lambeck]

This might be it - how do I access the data ?

Here's the sample from the perldoc:

.sub _some
# store the config data into $P0
$P0 = _config()
# Retrieve and print a key
$P1 = $P0["cc"]
print "Your C compiler is "
print $P1
print "\n"
.end
.include "library/config.imc"

Which, when run on my OS X box, gives:

oolong:~/research/parrot coke$ ./parrot foo.imc
Your C compiler is cc

How's that?

I will try it out to see if it works for me. Now I know how to get the data
but how can I include this into a Makfile. If this were Perl-code I could use
MakeMaker but this way I need to do it somehow different.
By the way - in which file did you find this example.

There's a TODO item in the bug tracker, which describes an extension to
parrot-config.imc.

$ ./parrot parrot-config.imc libs
-lnsl -ldl -lm -lposix -lcrypt -lutil -lpthread -lrt -lgmp

It should eventually understand shortcuts like --compile or --link or
some such.

For now you can include something like:

foo$(EXE) : foo.c $(PARROT) # or better the lib
`$(PARROT) parrot-config.imc link` \
`$(PARROT) parrot-config.imc libs` \
...

in the Makefile.
