## Compilation
|
||||
|
||||
### GUI
|
||||
|
||||
By default the X11 version is built. It is the most complete UI-wise.
|
||||
|
||||
To build the X11 version run `make GUI=x11`
|
||||
|
||||
To build the SDL1 version run `make GUI=sdl1`
|
||||
|
||||
### Debugger
|
||||
|
||||
Debugger is not built by default.
|
||||
To build the debugger compile with `make WITH_DEBUGGER=yes`
|
||||
|
||||
## Installation
|
||||
|
||||
1. Run `sudo make install PREFIX=/usr DOCDIR=/usr/doc/x48ng MANDIR=/usr/man DESTDIR=/tmp/package` filling in your own values for PREFIX, DOCDIR, MANDIR and DESTDIR.
