GNU make is required to build disktype. The Makefile is set up to use GCC, but disktype should compile with any C compiler. To change the compiler, you can edit the Makefile or set the standard variables CC, CPPFLAGS, CFLAGS, LDFLAGS, and LIBS from the make command line.

The Makefile uses uname to determine the system type and enables certain system-dependent features based on that. If you run into problems, you can disable all system-dependent features by setting the variable NOSYS, as in make NOSYS=1.

Running make results in the binary disktype. Copy it to a bin directory of your choice, optionally stripping it on the way. That's all.
