Compiling under Linux/Mac OS

Note: If you are using Mac OS you will also need to install - if not already present - the following required (additional) tools.

• GNU Bison from http://www.gnu.org/software/bison/bison.html.
• GNU Flex from http://flex.sourceforge.net/.
• GNU Sed from http://www.gnu.org/software/sed/sed.html.

1. Download the archive gcx_2-1_src.tar.gz (you might also download the .zip archive gcx_2-1_src.zip) from http://sourceforge.net/project/showfiles.php?group_id=258398.
2. Extract the archive by typing

   > tar -xzf gcx_2-1_src.tar.gz

   in a shell. This will create the following directory structure.
   
   

   gcx_2-1_src		The root folder.
   ./bin		This folder is empty and will - after compilation - contain the binary.
   ./examples		This folder contains sample queries for testing purpose.
   ./sgml		This folder contains sgml sample queries.
   ./tree		This folder contains tree sample queries.
   ./xmark		This folder contains xmark sample queries.
   ./xmp		This folder contains xmp sample queries.
   ./src		This folder contains all required sources for compilation.

3. Step into the src directory by typing

   > cd ./gcx_2-1_src/src

   in a shell.
4. Optionally, but not necessarily, you may want to enable or disable one or more special features by uncommenting or adding FLAGS in the Makefile (Makefile.Linux). A complete list of all available compilation FLAGS will be discussed in Section Compiling with/without Special Features.
5. Now type

   > make -f Makefile.Linux

   to compile the sources. After compilation a binary file named gcx will be created in the bin directory.
6. You might also consider to add the bin directory to your PATH variable or creating a link to the gcx binary in /usr/bin.
