Issue: loading cffi-libffi, CFFI fresh from git repository
Platform: - 64-bit windows 7 - MSYS2 & MinGW64 - CCL1.11 or SBCL 1.30.0 - CFFI, fresh from git
I downloaded from github and got qualified success:
- At first loading I had to specify the path to ffi.h using
cffi::*cc-flags*
for the compilation to proceed
That's unexpected. Does that mean it failed to execute pkg-config? If the compilation log doesn't yield any tips, perhaps you could tweak the pkg-config-cflags definition (in cffi/grovel/grove.lisp) to add some debugging output and see what's going on there?
Running in the shell
pkg-config libffi --cflags
returns:
-IE:/msys64/mingw64/lib/libffi-3.2.1/include
as expected.
I traced INVOKE, and UIOP/RUN-PROGRAM:RUN-PROGRAM.
The problem originates in reading the output of uiop/run-program:run-program. Here are the trace outputs for (CFFI-TOOLCHAIN:INVOKE "pkg-config.exe" "--version"):
<1 UIOP/RUN-PROGRAM:RUN-PROGRAM returned 3 values : <1 NIL <1 NIL <1 0 <0 CFFI-TOOLCHAIN:INVOKE returned 3 values : <0 NIL <0 NIL <0 0
For some reason, the output of pkg-config is not being read.
I will play with CCL:run-program to get output out of it, and then trace this back to uiop and invoke.
