Files in this directory are used to update the source in this distribution with updates from the FreeBSD CVS source. 1) cvs_export.sh - get the source from cvs (to ./export) 2) patches_apply.sh - try to patch ./export with current pathes. 3) patches_check.sh - check updated ./export against dist 4) update_dist.sh - update dist and version If by hand: *) copy ./export/* files to dist '""cp -rf export/* ..' *) 'rm -rf export; cp -rf export.unpatched export' - get clean ./export hierarchy *) patches_make.sh - make new patches to be distributed *) update 'vi ../Makefile.am with' list ':r !./extra_dist_list.sh' (vim cmd) *) update LT_VERSION in configure.ac according to the below Note 5) update ChangeLog 6) autoreconf && make distcheck!!! http://developer.gnome.org/doc/books/WGA/dealing-with-libraries.html#AEN555 A Note about Version Numbers The three numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The libtool script typically tacks these three numbers onto the end of the name of the .so file it creates. The formula for calculating the file numbers on Linux and Solaris is (C - A).(A).(R), so the example given here would create the file libgrump.so.3.2.1. Other operating systems might use a different library file name convention; libtool takes care of the details. As you release new versions of your library, you will update the library's C:R:A. Although the rules for changing these version numbers can quickly become confusing, a few simple tips should help keep you on track. The libtool documentation goes into greater depth. In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number. This is called your interface number. The main use of this interface number is to tag successive revisions of your API. The AGE number is how many consecutive versions of the API the current implementation supports. Thus if the CURRENT library API is the sixth published version of the interface and it is also binary compatible with the fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When you break binary compatibility, you need to set AGE to 0 and of course increment CURRENT. The REVISION marks a change in the source code of the library that doesn't affect the interface-for example, a minor bug fix. Anytime you increment CURRENT, you should set REVISION back to 0.
