automake / autoconf question
|

| Erwan Loisant 2004-10-25, 3:59 am |
| Hello.
I am packaging a library I made, and I have a (I think) basic question
on automake/autoconf. I am new to comp.unix.programmer and I hope my
question is not off-topic.
This is a C library, and I found good documentation on how to package
it in a clean way. However I also have Ruby bindings (a scripting
language) and to produce the Makefile of these bindings I need to
launch a given command (actually "ruby extconf.rb".
How can I modify my configure.in to say "in this directory, please
launch the given command /then/ make" ?

AFAIK you can just put your ruby command in configure.in. Something like:
AC_INIT([My Program], [0.2], [you@somewhere.com], [myprog])
AC_CONFIG_SRCDIR([main.c])
AC_PREREQ(2.57)
AM_INIT_AUTOMAKE
AC_CONFIG_HEADERS([config.h])
AC_PROG_CC
AC_PROG_INSTALL
cd ruby/bindings/directory
ruby extconf.rb
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
There's probably a more elegant way to do this, but for just one
ruby-command I wouldn't bother if it works.

P.S. Note this example is actually for a autoconf version > 2.5x, but
this shouldn't make for your question.

Never change directories like that, do something like this instead:
(cd ruby/bindings/directory && ruby extconf.rb)
This will run the cd and ruby comands in a subshell, so the working
directory of the configure script doesn't change.

Oops...
Thanks for pointing that out.
