Description Tim Waugh 2005-06-13 13:59:38 UTC 
Description of problem:
When using subdir-objects, this sort of thing should work:

AC_CHECK_FUNCS(getopt_long , , [
  AC_LIBOBJ(src/getopt)
  AC_LIBOBJ(src/getopt1)
])

and in previous automake releases it did.  With automake-1.9.5-1 it says those
files do not exist (when they do).

Version-Release number of selected component (if applicable):
automake-1.9.5-1

How reproducible:
100%

Steps to Reproduce:
See attached tarball.
1. tar jxf foo-0.0.1.tar.bz2; cd foo-0.0.1
2. aclocal
3. automake
  
Actual results:
Makefile.am:4: required file `./src/getopt.c' not found
Makefile.am:4: required file `./src/getopt1.c' not found

Expected results:
No errors.

FWIW, this was distilled from the patchutils package.
Comment 3 Karsten Hopp 2006-08-02 13:00:03 UTC 
Tom, any idea how to fix this ?
I've already tried AC_CONFIG_LIBOBJ_DIR([src]), but automake doesn't seem to use it.
That's with automake-1.9.6-2.1, btw.
Comment 4 Tom Tromey 2006-08-03 17:29:38 UTC 
I'm afraid I don't really know.  I haven't been actively involved
in automake for quite a while.
All I can really suggest is an upstream bug report, sorry :(
Comment 5 Ralf Wildenhues 2006-10-20 13:11:58 UTC 
Automake 1.10 is out now.  It supports AC_CONFIG_LIBOBJ_DIR.  So now you should
be able to write

AC_INIT
AC_CONFIG_LIBOBJ_DIR([src])
AM_INIT_AUTOMAKE([1.10 subdir-objects])
# ...
AC_CHECK_FUNCS(getopt_long , , [
  AC_LIBOBJ(getopt)
  AC_LIBOBJ(getopt1)
])


Hope that helps.
Comment 6 Stepan Kasal 2007-10-29 17:15:32 UTC 
If there is only one libobj directory, then comment #5 shows the way.

Current Autotools do not support more than one libobj directory; if that was
what you needed, please discuss it upstream (lists bug-auto{make,conf} at gnu.org).
