GCC-XML

Note: GCC-XML has been succeeded by CastXML.

Introduction

This program dumps an XML description of C++ source code using an extension of the GCC C++ compiler.

This document is intended as supplement to the documentation on the GCC-XML homepage. More extensive instructions may be found there.

Build/Install

The standard way to build the GCC-XML front-end is to use CMake (see links at bottom to get it). CMake will generate an appropriate build system for your platform and compiler. There are separate instructions for UNIX and Windows users.

UNIX & Cygwin

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):

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

(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).

Windows

Run the CMake GUI to generate the build system for your compiler. Load the resulting project file and build it. You should be able to run the executable directly from the build directory. It will be located in gccxml-build/bin, gccxml-build/bin/Debug, or gccxml-build/bin/Release depending on the build system chosen.

Solaris

Sun's CC 5.8 is supported. You need modified headers to use gccxml with CC 5.8. You need to follow the instructions in GCC_XML/Support/Sun/README.

Running

Once GCC-XML has been properly configured, it can be run from the command line like this:

$ gccxml input.cxx -fxml=output.xml

Use gccxml --help for a full list of options and configuration help.
