Subject svn commit: r502202 - /apr/apr/trunk/build/jlibtool.c
Date Thu, 01 Feb 2007 12:30:18 GMT
Author: jerenkrantz
Date: Thu Feb  1 04:30:17 2007
New Revision: 502202

URL: http://svn.apache.org/viewvc?view=rev&rev=502202
Log:
Have jlibtool match GNU libtool's behavior when creating a static library that
links against another static library by importing all objects into the new
static library.  Part of this functionality was there, but it was dormant.
Also avoid 'touch'ing a file when we don't want a fake output name.

* build/jlibtool.c
  (pop_count_chars): Make it easy to reduce the number of vals.
  (flatten_count_chars): Make the insertion of the space optional.
  (run_command): Update flatten_count_chars.
  (safe_mkdir): Factor out our mkdir sequence.
  (jlibtool_basename, nameof): Move earlier in file.
  (explode_static_lib): Move earlier and rewrite it so it works.
  (parse_input_file_name): Explode the static lib if we're creating a library.
  (run_mode): Call safe_mkdir.
  (ensure_fake_uptodate): If we don't have a fake output name specified,
  don't call touch.
