Introduction to GC
The GC package contains the
Boehm-Demers-Weiser conservative garbage collector, which can be
used as a garbage collecting replacement for the C malloc function
or C++ new operator. It allows you to allocate memory basically as
you normally would, without explicitly deallocating memory that is
no longer useful. The collector automatically recycles memory when
it determines that it can no longer be otherwise accessed. The
collector is also used by a number of programming language
implementations that either use C as intermediate code, want to
facilitate easier interoperation with C libraries, or just prefer
the simple collector interface. Alternatively, the garbage
collector may be used as a leak detector for C or C++ programs,
though that is not its primary goal.
This package is known to build and work properly using an LFS 12.2
platform.

Installation of GC
Install GC by running the
following commands:
./configure --prefix=/usr \
--enable-cplusplus \
--disable-static \
--docdir=/usr/share/doc/gc-8.2.6 &&
make
To test the results, issue: make
check.
Now, as the root user:
make install &&
install -v -m644 doc/gc.man /usr/share/man/man3/gc_malloc.3
Command Explanations
--docdir=/usr/share/doc/gc-8.2.6:
This option is used so the package will install the documentation
in a versioned directory.
--enable-cplusplus: This
parameter enables the building and installing of the C++ library
along with the standard C library.
--disable-static: This
switch prevents installation of static versions of the libraries.
