Revision 1639 - (show annotations) (download)
Sat Jan 12 14:13:46 2008 UTC (11 years, 8 months ago) by schoenebeck
Original Path: linuxsampler/trunk/configure.in
File size: 48582 byte(s)
* autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
  causing e.g. the libgig test to fail when
  "./configure --disable-jack-driver" was used
  (patch by Alexis Ballier)

11 # The following is the libtool / shared library version. This doesn't have to
12 # do anything with the release version. It MUST conform to the following rules:
13 #
14 # 1. Start with version information of `0:0:0' for each libtool library.
15 # 2. Update the version information only immediately before a public release of
16 # your software. More frequent updates are unnecessary, and only guarantee
17 # that the current interface number gets larger faster.
18 # 3. If the library source code has changed at all since the last update, then
19 # increment revision (`c:r:a' becomes `c:r+1:a').
20 # 4. If any interfaces have been added, removed, or changed since the last update,
21 # increment current, and set revision to 0.
22 # 5. If any interfaces have been added since the last public release, then increment
23 # age.
24 # 6. If any interfaces have been removed since the last public release, then set age
25 # to 0.
