[Cffi-devel] Cannot load cffi-libffi

[Liam Healy]

On Debian/Ubuntu and SBCL, I cannot load the latest cffi-libffi

To load "cffi-libffi":
  Load 1 ASDF system:
    cffi-libffi
; Loading "cffi-libffi"
; pkg-config libffi --cflags
; cc -m64 NIL -I/home/healy/languages/lisp/cffi/ -o
/home/healy/.cache/common-lisp/sbcl-1.2.3.29-d15420c-linux-x64/home/healy/languages/lisp/cffi/libffi/libffi-unix
/home/healy/.cache/common-lisp/sbcl-1.2.3.29-d15420c-linux-x64/home/healy/languages/lisp/cffi/libffi/libffi-unix.c

debugger invoked on a CFFI-GROVEL:GROVEL-ERROR in thread #<THREAD "main
thread" RUNNING {1002BEE843}>: External process exited with code 1.
Command was: "cc" "-m64" "NIL" "-I/home/healy/languages/lisp/cffi/" "-o"
"/home/healy/.cache/common-lisp/sbcl-1.2.3.29-d15420c-linux-x64/home/healy/languages/lisp/cffi/libffi/libffi-unix"
"/home/healy/.cache/common-lisp/sbcl-1.2.3.29-d15420c-linux-x64/home/healy/languages/lisp/cffi/libffi/libffi-unix.c"
Output was:
cc: error: NIL: No such file or directory


Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [RETRY                        ] Retry PROCESS-OP on #<GROVEL-FILE
"cffi-libffi" "libffi" "libffi">.
  1: [ACCEPT                       ] Continue, treating PROCESS-OP on
#<GROVEL-FILE "cffi-libffi" "libffi" "libffi"> as having been successful.
  2:                                 Retry ASDF operation.
  3: [CLEAR-CONFIGURATION-AND-RETRY] Retry ASDF operation after resetting
the configuration.
  4: [ABORT                        ] Give up on "cffi-libffi"
  5:                                 Exit debugger, returning to top level.

I bisected this down to this commit:
     4d5479d692f07c641d3218c4728fa43287528366 is the first bad commit

         Find cc-flags for libffi using pkg-config on linux.
