/* There are two options:
|
||
|
|
|
||
|
|
=====1=====
|
||
|
|
|
||
|
|
Link this program with _embedding_test.so.
|
||
|
|
E.g. with gcc:
|
||
|
|
|
||
|
|
gcc -o embedding_test embedding_test.c _embedding_cffi*.so
|
||
|
|
|
||
|
|
You must then run the executable with the right command
|
||
|
|
(LD_LIBRARY_PATH on Linux), otherwise it won't find the
|
||
|
|
_embedding_cffi*.so:
|
||
|
|
|
||
|
|
LD_LIBRARY_PATH=. ./embedding_test
|
||
|
|
|
||
|
|
There are platform-specific options to gcc to avoid needing
|
||
|
|
that, too. Linux:
|
||
|
|
|
||
|
|
gcc -o embedding_test embedding_test.c _embedding_cffi*.so \
|
||
|
|
-Wl,-rpath=\$ORIGIN/
|
||
|
|
|
||
|
|
=====2=====
|
||
|
|
|
||
|
|
Compile and link the _embedding_test.c source code together with
|
||
|
|
this example (e.g. with PyPy):
|
||
|
|
|
||
|
|
gcc -o embedding_test embedding_test.c _embedding_cffi.c \
|
||
|
|
-I/opt/pypy/include -pthread -lpypy-c
|
||
|
|

|

|
|

|

int main(void)
|
||
|
|
{
|
||
|
|
int res = add(40, 2);
|
||
|
|
printf("result: %d\n", res);
|
||
|
|
res = add(100, -5);
|
||
|
|
printf("result: %d\n", res);
|
||
|
|
return 0;
|
||
|
|
}
