Loading cffi on openSuse Tumbleweed results in two errors.
The first one,
(FL-ERROR "Unable to load any of the alternatives:~% ~S" ("libffi.so.6" "libffi32.so.6" "libffi.so.5" "libffi32.so.5"))
is easily solved by providing ("libffi.so") as a value to be used instead.
This is because Tumbleweed comes with libffi7, from git. As far as I can tell from
their package changelog, it's https://github.com/libffi/libffi/tree/60e4250a77eb3fde500bfd68ec40519fe34b21bd .
This leads to another problem:
grov.c: In function ‘main’:
grov.c:72:41: error: ‘FFI_SYSV’ undeclared (first use in this function)
fprintf(output, "%"PRIiMAX, (intmax_t)FFI_SYSV);
FFI_SYSV isn't defined because ffi_abi struct in ffitarget.h resolves to
#elif defined(X86_64) || (defined (__x86_64__) && defined (X86_DARWIN))
FFI_FIRST_ABI = 1,
FFI_UNIX64,
FFI_WIN64,
FFI_EFI64 = FFI_WIN64,
FFI_LAST_ABI,
FFI_DEFAULT_ABI = FFI_UNIX64
leaving FFI_SYSV undefined.
As a temporary fix, I added #define FFI_SYSV 1 to grovel/common.h, and compiling worked
just fine for my case (https://github.com/vydd/sketch/issues/17#issuecomment-303260982),
but a proper patch is needed. |

I don't know nearly enough about cffi internals to be sure it doesn't break other stuff. Otherwise I'd post this as a pull request. |
