Neni to tak hrozne, jak ta tabulka naznacuje. Zaprve: porty na dalsi platformy byly, ale kvuli male aktivite v teto oblasti to neni podporovano. Nicmene to, ze je tam napsano "not supported" neznamena, ze by tam Factor nefungoval - radkova verze pracuje temer na 100%, u GUI si nejsem tak jisty, ale minimalne OpenBSD s OGL na X11 funguje.
Ono vlastne krome par volani specifickych API tam nic extra neprenositelneho neni.
Jeste aby to nevypadalo, ze moc kecam, tak tady je komentar samotneho Slavy Pestova:
Factor in darcs now runs on OpenBSD/x86. Porting to OpenBSD on top of PowerPC, ARM and other CPU architectures is trivial but not automatic: unlike Linux, the ucontext_t structure, used in signal handlers, is CPU-specific.
You will need to install a gcc version more recent than 3.3 on your OpenBSD box. Upgrading gcc seems to be a non-trivial affair.
Also, at one time we had testers for Solaris/x86 and Linux/PPC. Not anymore, unfortunately, and recent changes to the runtime and FFI lead me to believe that Factor may no longer work on these platforms. I'm going to test Factor on Linux/PPC before releasing 0.88, but I don't have the time, inclination or hardware to maintain a Solaris/x86 install. If you're interested in seeing support, please post to the mailing list or drop by #concatenative.
