Mkmf: how to include .c and .h files within a subdirectory?

Hi, having the following file tree under my ext/ directory:

my_ext/
extconf.rb
my_ext.c
utils/
utils.c
utils.h

How to say in extconf.rb that files under utils/ subdirectory must
also be compiled?

Thanks a lot.

Thanks a lot.

I’ve once had the same problem and asked here on Ruby T., but got no
satisfying answer. It is not possible without hacking mkmf, I finally
ended up putting everything in one directory. #create_makefile
(http://ruby-doc.org/stdlib-1.9.3/libdoc/mkmf/rdoc/Object.html#method-i-create_makefile)
has an option for specifying one subdirectory where all files reside,
but for multiple subdirectories you’d have to create multiple C
extensions.

If someone knows another way to accomplish the task, I’d be intererested
in it, because large C extensions are easier organised by use of
multiple directories.

Vale,
Marvin

Though, IMO, there is no official way, here is a hack.


require ‘mkmf’

set all object files to $objs before create_makefile.

$objs = [“my_ext.o”, “utils/utils.o”]

create_makefile(“my_ext”)

to clean up object files under util subdirectory.

open(‘Makefile’, ‘a’) do |f|
f.write <<EOS

CLEANOBJS := $(CLEANOBJS) utils/*.#{CONFIG[“OBJEXT”]}
EOS
end

But it doesn’t work for rubinius.
Thanks a lot. Very useful information.
