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.

本パッケージは LFS-11.1 において正しくビルドでき動作することが確認されています。

Installation of GC

Install GC by running the following commands:

./configure --prefix=/usr      \
            --enable-cplusplus \
            --disable-static   \
            --docdir=/usr/share/doc/gc-8.0.4 &&

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-8.0.4: 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: このスイッチはスタティックライブラリをインストールしないようにします。
