P.I.G.A.L.E. Public Implementation of a Graph Algorithm Library and Editor H. de Fraysseix      P. Ossona de Mendez

Compilation and Installation

This package includes the source files of a stand alone library tgraph, the editor pigale and the client program .
The editor is based on the Qt toolkit and uses the OpenGL libraries for the 3-dimensional drawings.
g++ and Mesa3D are available under the GNU license.
Qt is free under Unix with a GPL license, and there exists a non-commercial license under Windows.

• g++ compiler: g++-2.96 or g++-3.xx (GCC home page)
• Qtlibrary: 3.0 (at least 2.3.1), with openGL support (Qt home page)
• OpenGL : Mesa3D-3.4. (Mesa 3D home page)
• glut libraries (OpenGl)
• Doxygen (Documentation tool). (Doxygen home page)

Linux

The Mesa 3D libraries are included in XFree86 version 4, but sometimes the glut library is not.
The QT libraries are included in all Linux distributions providing access to KDE.
Doxygen is only needed if you want to create the on line documentation.

Using configure

• Run the configure script: ./configure [options]
  • By default, the prefix for installation is /usr/local/pigale.
  • If you don't have a write permission, you must provide another directory where you have a write permission:
    ./configure --prefix=/home/a_directory.
  • Usually the location of the installation of Qt is defined by the environment variable QTDIR.
  • For more options run: ./configure --help
    These options, in particular, let you enable a debug mode, let you precise the locations of the Qt libraries, etc.
• Next run the following command:
  make install

Using make

The files pigale/gnumakefile, pigale/tgraph/gnumakefile ,pigale/ClientServer/gnumakefile and pigale/qt/gnumakefile might need to be edited for particular goals (level of optimization, location of files, etc.).

The command make -f gnumakefile creates the libraries in pigale/lib and the executable programs in pigale/qt and pigale/ClienServer .

If you don't have root permission, you can create static versions of Pigale by typing: make static , after the libraries has been created (name is then spigale_xxx instead of pigale_xxx).

• If the variable OPT is set to dbg (debugging mode) the resulting programs is named pigale_dbg.
• If the variable OPT is set to opt (optimize mode) the resulting programs is named pigale.

This program has also been compiled under different UNIX systems, using the gcc compilers.

Windows

Pigale has been compiled with the following:

• Microsoft compiler,
• Qt-3.3 toolkit,
• OpenGL libraries included in Windows,
• glut libraries.
