[cffi-devel] cffi-uffi-compat library searching
by Nathan Bird 13 Jun '06

13 Jun '06

I am using cffi-uffi-compat with clsql recently... ended up doing so because I need :long-long for sqlserver bigints. However, in trying to get it to work, I found a problem with the way it searches for libraries to load. If you just tell it to load libodbc.so, at least on sbcl the underlying functionality is capable of searching the default library paths to find it. CFFI was shortcutting that and not calling the next function if probe-file failed. Now it only does the probing if it is a full path and not just the filename. This also matches the behavior of UFFI, which is probably a good thing for cffi-uffi-compat. Nathan Bird

[cffi-devel] corrupted foreign structure testcase with latest CFFI and LW 4.4.6
by Jack Unrue 07 Jun '06

07 Jun '06

I've run into a problem where populating a foreign structure and then passing it to a foreign function behaves correctly if my Lisp code is interpreted, but the structure fields appear to be corrupted if my function is compiled. This is with CFFI versions later than 0.9.0, and on LW 4.4.6 under WinXP. When I invoke the dump-it function in interpreted mode, the output file contains the expected result: cbSize: 4 style: 01abcdef When I (compile 'dump-it) and then invoke it, the output file contains garbage: cbSize: -1412567292 style: 01abcd01 This testcase works fine with the same LW version but CFFI 0.9.0. It also works fine with CLISP 2.38 and latest CFFI. CFFI versions 0.9.1, 060514, and a build produced from a darcs pull today all show the problem on LW. I haven't tried bisecting any further. See attached testcase.lisp and structs.c. I've also attached a simple Makefile for compiling with gcc. The foreign function dump_blah writes a file called 'dump_output.txt' in the current working directory. -- Jack Unrue

[cffi-devel] Passing a struct by value
by Luke Crook 07 Jun '06

07 Jun '06

I've read: http://article.gmane.org/gmane.lisp.cffi.devel/754 stating that CFFI does not support passing structs by value. Unfortunately I need to pass a SDL_Color struct *by value* to the SDL_ttf library in order to set the character/font color prior to rendering. I'll need to write some 'glue' code in C to do this conversion. Does anyone have any suggestions on the best way I should implement this? A 'wrapper' function in a helper DLL that will take the SDL_Color struct pointer from CFFI and call the SDL_ttf function passing the struct as a value? Thanks, -Luke

[cffi-devel] lisp-var-name
by Nikodemus Siivola 27 May '06

27 May '06

In CFFI 0.91 LISP-VAR-NAME breaks if passed a symbol. Hence (defcvar environ :pointer) fails, despite documentation claiming this to be legal. Seems like a missing leg in the etypecase.

...due to intptr_t not being a known type. Adding #include <stdint.h> after other includes makse everything work. Cheers, -- Nikodemus Schemer: "Buddha is small, clean, and serious." Lispnik: "Buddha is big, has hairy armpits, and laughs."
