When running on a "freebsd-gnu", plataform is unknown

[ercdude]

Hello!

I'm trying to run cl-bodge with sbcl, but it seems that my plataform is not recognized? I'm not sure why it has gnu on it, but seems to be a problem.

I've tried to add the key to the constant +known-plataforms+, but I guess it needs more than that.

I'm a newbie at common-lisp, maybe I'm losing something?

Thanks!

• **What I did:***

I've made a fresh install of quick lisp, installed bodge with (ql-dist:install-dist "http://bodge.borodust.org/dist/org.borodust.bodge.txt"). Restarted the sbcl and then:

CL-USER> (load "/usr/home/eric/quicklisp/setup.lisp")
T
CL-USER> (ql:quickload :bodge-demo)

• The error:

Thank you for the report. Unfortunately, freebsd is not supported at the moment.

[ercdude]

Oh, okay :/ I saw that +known-plataforms+ already knows about freebsd and I fought that it was supported.

How hard it is to implement it? May you point some path where I could look at?

[borodust]

For a newcomer that will require a tremendous effort. cl-bodge uses foreign libraries extensively, meaning you would need to port a bunch of those to FreeBSD (compile them and generate bindings). To accomplish this, one would need to understand how C (and related tech), CFFI and :claw works. :claw doesn't have any docs atm and is undergoing a HUGE rewrite to support C++. This is a massive task even for a seasoned Common Lisp programmer.

Once I'm done with :claw rewrite, I might look into FreeBSD support myself, but no promises. This mostly depends on whether those foreign libraries do actually support it.

For a FreeBSD user, I suggest looking into other CL game engines for now. Candidates are (in no particular order): Sketch, Xelf, Trial.

thank you for the detailed information! it seems a lot, indeed.

I will start with those libraries while keeping an eye over cl-bodge :) maybe I can help in the future, if it's still needed.

Thanks! And have a good day :)
