Requirements
|
|
------------
|
|
In order to build $name you need the LIBRARY header files.
|
|
|
|
|
|
Instillation
|
|
------------
|
|
Edit config.mk to match your local setup ($name is installed into
|
|
the /usr/local namesapce by default).
|
|
|
|
Afterwards enter the following command to build and install $name (if
|
|
necessary as root):
|
|
|
|
make clean install
|
|
|
|
Running $name
|
|
$(echo "Running $name" | sed 's/./=/g')
|
|
To run $name use the following command:
|
|
|
|
./$name
|
|
|
|
Configuration
|
|
-------------
|
|
The configuration of $name is done by creating a custom config.h
|
|
and (re)compiling the source code.
