Two types of executables files exist: elf and rar (all lowercase). elf can be executed directly, whereas rar must contain an elf with the SAME name. The version of the RAR compressor used must be 2.X or it will not work.

les elf et les rar ...la doc complète de mcloader est dans le rar dans la section downloads, fichier readme.doc...

Une question c'es quoi ca comme language C... pas reussi à le compiler...
