./devel/boehm-gc, Garbage collection and memory leak detection for C and C++

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 7.6.4nb3, Package name: boehm-gc-7.6.4nb3, Maintainer: pkgsrc-users

The Boehm-Weiser garbage collection package, for C and C++ -
garbage collection and memory leak detection libraries.

A garbage collector is something which automatically frees malloc'd
memory for you by working out what parts of memory your program
no longer has pointers to. As a result, garbage collectors can also
inform you of memory leaks (if they find memory they can free, it means
you have lost all of your pointers to it, but you didn't free it).

This package has two libraries and some include files:
libgc.a - a garbage collection library, replaces malloc/free/new/delete/etc
with versions that do automatic garbage collection
libleak.a - a leak detection library, which is just libgc.a compiled with
different switches.

C programs may be linked against either of these, and should run (with
GC or leak detection) without change. C++ programs must include a header
to use garbage collection, though leak detection should work without
such source code modifications. See the man page and header files.

PS: garbage collection is addictive.

Log message:
boehm-gc: add upstream commit for libtool version

In 7.6.2, upstream intentionally but badly-advised bumped their
library major version number. In 7.6.4, they'll undo that change.
Instead of bumping twice in pkgsrc, follow their lead and get the
change in now.

See https://github.com/ivmai/bdwgc/issues/197
