[CVS] Can not cross-compile assembly stuff with libtool

SDL Development

Hello,
I tried building (cross-compiling) latest SDL cvs, and got this error with
one file (I separated the different lines of the make output):

It appears libtool uses the native ‘as’ assembler, instead of the
cross-compiler’s one (m68k-atari-mint-as in my case). I also checked some
autoconf stuff I wrote and that works. It seems you need to add a
AM_PROG_AS to configure.in, and maybe it would be also needed to migrate
configure.in to configure.ac with autoconf>2.5 and automake>1.7 when using
libtool 1.5 (but I may be wrong).–

Can you make the requisite configure.in changes, test them, and send a patch
directly to me?
Please don’t check it in, as the automake stuff is very delicate.

Thanks!

OK, I will try as soon as possible.

Well, in fact after numerous tries, I manage to get where something was
failing: as seen in my first post, libtool was calling ‘as’ to assemble .S
into .lo and this is wrong: the rest of the command line is for
the gcc frontend. Thus, I just added a ‘AS=m68k-atari-mint-gcc’ to my
cross-configure script, and all was ok again. Sorry for the fear and
disturbance :-)–
