These instructions assume that the front-end will be built out-of-source (recommended), but an in-source build should also work. The example command lines assume the current working directory is just above the top-level source directory (called gccxml-master):

[root@localhost tools]# unzip gccxml-master.zip
[root@localhost tools]# cd /opt/tools/

$ mkdir gccxml-build; cd gccxml-build
// $ cmake ../gccxml-master -DCMAKE_INSTALL_PREFIX:PATH=/installation/path
$ cmake ../gccxml-master
$ make

(The "-D..." option can be left off if you want to use /usr/local as the installation prefix.)

This will install executables called gccxml and gccxml_cc1plus in PREFIX/bin. Support library files will also be placed in PREFIX/share/gccxml-(version).
