Problem compiling for linux 2.6

Problem compiling for linux 2.6

[Giuliano Pochini]

It fails at line #113 of /Makefile :

        @for d in $(SUBDIRS); do if ! $(MAKE) -C $$d prepare; then exit 1; fi; done

I have no idea why $(SUBDIRS) is an empty string:


[Giu@Jay alsa-driver-1.0.2]$ ./cvscompile --with-cards=powermac --with-isapnp=no --with-sequencer=no --with-oss=no --with-kernel=/opt/KernelSrc/l26 --with-debug=full

I'm using ALSA-1.0.2 after it was reuploaded. With linux 2.4 is compile just
fine as usual. I'm using 2.6 for the first time... maybe I forgot to
install/update something. :)

note that --with-isapnp is ignored on 2.6 kernel.
the isapnp support depends only on the kernel itself.

does the attached patch work?

Ok, I used that option only to avoid compiling useless stuff.

Yes it works. I compiled the modules successfully, after a few minor
changes to my code. Thanks.

It only complains about SUBDIRS, but it seems harmless:

  Building modules, stage 2.
/home/Giu/l26/scripts/Makefile.modpost:17: *** Uh-oh, you have stale module entries. You messed with SUBDIRS,
/home/Giu/l26/scripts/Makefile.modpost:18: do not complain if something goes wrong.
  MODPOST
