The prebuilt/ directory provides prebuilt binaries for Linux, Mac OS X, Windows and Atari ST.
The samples/ directory provides protected programs samples.
See the samples/README.txt file for detailed information.
The src/ directory contains the dec0de.c source file.
The source file can be compiled on any Operating System supporting gcc.
For non-Linux systems, the following gcc ports are available:
- gcc for Mac OS X
https://github.com/kennethreitz/osx-gcc-installer - gcc for Windows
http://www.mingw.org - gcc for Atari
http://vincent.riviere.free.fr/soft/m68k-atari-mint
Depending on the target Operating System, run gcc as follows:
- Linux
$ gcc -O -Wall -Wextra -m32 -static dec0de.c -o dec0de - Mac OS X
$ gcc -O -Wall -Wextra -m32 -mmacosx-version-min=10.5 dec0de.c -o dec0de - Windows
$ gcc -O -Wall -Wextra -std=c99 dec0de.c -o dec0de.exe - Atari ST
$ m68k-atari-mint-gcc -O -Wall -Wextra dec0de.c -o dec0de.prg
or
$ m68k-atari-mint-gcc -O -Wall -Wextra dec0de.c -o dec0de.ttp
On Linux, Mac or Windows, run the dec0de program from the command prompt.
To obtain usage information, run the program as follows:
$ dec0de -h
On Atari ST, launch dec0de.prg or dec0de.ttp from the GEM desktop.
dec0de.prg provides an interactive mode, while dec0de.ttp expects
parameters to be provided through the command line.
