To build, simply navigate to the directory containing the version you wish to build and run the build script.
For example, to build the x86 version, you'd use
cd i386 && ./create-elf32.sh
You may or may not have to give the script execute permissions with chmod
.
You can pass the name you wish to give the generated ELF file as an argument to the build script. Ex:
./create-elf32.sh elf-file-name
If the no name is passed, the build script will simply prompt the you to input a name. If nothing is entered, the default name is used.
