# Building
|
|
||||||
----------
|
|
||||||
## Dependencies
|
|
||||||
To compile the project you will require:
|
|
||||||
* C99 compatible compiler (GCC is recommended)
|
|
||||||
* UNIX Make
|
|
||||||
* X11
|
|
||||||
|
|
||||||
## Compiling
|
|
||||||
The project is built using the `make' command. For debug information
|
|
||||||
append `DEBUG=1' to the command.
|
|
||||||
|
|
||||||
# Installation
|
|
||||||
--------------
|
|
||||||
Once the project is built, you can install by running `make install'. By
|
|
||||||
default the `PREFIX' variable is set to `/usr/local' (installing the
|
|
||||||
binary in `/usr/local/bin'). You can override this by appending
|
|
||||||
`PREFIX=<prefix>' to the install command.
