Compiles a source file to a compiled code file. See also the Compiler chapter.


compile source [fname]



(literal or ^string) the name of the file to be compiled.


(literal or ^string) optional, the name of the file to be created. If not given, the file will have the same filename and path as source. It will have a .gcg extension.


compile qxy.e;

In this example, the source path would be searched for qxy.e, which would be compiled to a file called qxy.gcg on the same subdirectory qxy.e was found.

compile qxy.e xy;

In this example, the source path would be searched for qxy.e which would be compiled to a file called xy.gcg on the current subdirectory.


  • The source file will be searched for in the source path if the full path is not specified and it is not present in the current directory.

  • The source file is a regular text file containing a GAUSS program. There can be references to global symbols, Run-Time Library references, etc.

  • If there are library statements in source, they will be used during the compilation to locate various procedures and symbols used in the program. Since all of these library references are resolved at compile time, the library statements are not transferred to the compiled file. The compiled file can be run without activating any libraries.

  • If you do not want extraneous stuff saved in the compiled image, put a new at the top of the source file or execute a new in interactive mode before compiling.

  • The program saved in the compiled file can be run with the run command. If no extension is given, the run command will look for a file with the correct extension for the version of GAUSS. The source path will be used to locate the file if the full path name is not given and it is not located on the current directory.

  • When the compiled file is run, all previous symbols and procedures are deleted before the program is loaded. It is therefore unnecessary to execute a new before running a compiled file.

  • If you want line number records in the compiled file you can put a #lineson statement in the source file or turn line tracking on from the main GAUSS menu, Tools > Preferences > Advanced.

  • Don’t try to include compiled files with #include.

  • GAUSS compiled files are platform and bit-size specific. For example, a file compiled with GAUSS for Windows 64-bit will not run under GAUSS for Windows 32-bit or on Linux 64-bit
