i have a test.c like below (in the same dir as the python file)
#include <stdio.h>
void myprint();
void myprint()
{
printf("hi\n");
}
and now i want to "import" it into my python script
from cffi import FFI
ffi = FFI()
ffi.cdef("void myprint();")
C = ffi.verify("""
#include "test.c"
""")
Using the examples from the cffi docs work fine.
Sorry for the large traceback error...
__pycache__/_cffi__xd52cd3eax2b8a27ce.c:185:18: fatal error: test.c: No such file or directory

Try ffi.verify(..., include_dirs=['.']). The compiler is not called from the current directory, but instead from some temporary directory where cffi creates its temporary files.
