MCCLIM : SYSTEM-AREA-UB8-FILL ?

[JVD]

Having followed Bug #1930309 , in trying to do:
  (ql:quickload "mcclim")
, on sbcl-2.1.6 linux x86_64 (Fedora 34), which I built
by modifying Fedora SRPM SPEC file to build 2.1.6 (no patches applied),
I at first got the error assembling MOVZX reported in Bug #19330309 ,
and then I built and installed the nibbles-master GIT zip,
and now I get a different error when attempting to build MCCLIM :

It seems that MCCLIM is expecting this SYSTEM-AREA-UB8-FILL function in
SBCL - any idea what it did ?

Has anyone got MCCLIM running under X-Windows + Linux + recent SBCL ?

[JVD (jason-vas-dias)]

 (apropos "SYSTEM-AREA") yielded:

   SB-KERNEL:SYSTEM-AREA-UB8-COPY

 Can I replace the call in static-vectors-v1.8.6/src/impl-sbcl.lisp:
  (sb-kernel:system-area-ub8-fill value pointer 0 length)
 with one to SYSTEM-AREA-UB8-COPY ?

 will try.

[JVD (jason-vas-dias)]

Yes, that did it! A lucky guess.
This patch, and use of nibbles-master, allows '(ql:quickload "mcclim")'
to succeed:

static-vectors is already updated for this change.

[Douglas Katzman (dougk)]

Also note that ub8-fill is not at all the same as ub8-copy.
-fill is memset(), -copy is memcpy().

[JVD (jason-vas-dias)]

Then where is system-area-ub8-fill ?

Why remove it ?

OK, I guess the correct resolution is to download
& build latest version of static-vectors .

Why didn't quicklisp update 'static-vectors' then?

I now realize I should have done a
  (ql:update-dist "quicklisp")
to update all out-of-date packages - sorry.

Actually, the MCCLIM:CLIM-EXAMPLES:demodemo worked well
with my change above . MCCLIM is impressive!

I want to work on (& use!) a CLIM compliant FLTK CL module / FLTK
+ XWayland / OpenGL backend to MCCLIM, amongst other projects -
"CLIM-FLTK" - SB-ALIEN's FFI capabilities are great ! FLTK works
great on Linux, Windows, Mac OS X ...

RE:
  > Also note that ub8-fill is not at all the same as ub8-copy.

Where is SB-KERNEL module documentation ?
I guess just reading the source code & (describe 'SB-KERNEL:*) ?
I'd like to understand it better. Are there any documents on it?

Thanks for all replies.
