For the (documented) libcc.fs C interface you need a C compiler at |

run-time. |
|
|
|
For the (undocumented ) lib.fs C interface you need to install either |
|
the ffcall libraries or the libffi library. Libffi comes with recent |
|
gccs, ffcall can be found on |

|
|
|
On many architectures (exceptions: 386, PPC, MIPS, Alpha) you need gdb |
|
at run-time in order for the disassembler to work. |
