GuillaumeCisco edited a comment on issue #38: Python wrappers URL: https://github.com/apache/incubator-milagro-crypto-c/issues/38#issuecomment-521321028 Thanks. I need a little help on this one. If I create rom.c like: ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h> #include <amcl/pair_FP256BN.h> int main() { BIG_256_56 q2; BIG_256_28 r2; printf("BLS381\n"); BIG_256_56_rcopy(q2, Modulus_FP256BN); printf("q (381) = 0x"); BIG_256_56_output(q2); printf("\n"); BIG_256_28_rcopy(r2 ,CURVE_Order_FP256BN); printf("r (257) = 0x"); } ``` Then how do I wrap it with cffi? If I write something like: ```python import cffi import platform ffi = cffi.FFI() ffi.cdef(""" int main(); """) if (platform.system() == 'Windows'): libamcl_wcc_FP256BN = ffi.dlopen("libamcl_wcc_FP256BN.dll") libamcl_core = ffi.dlopen("libamcl_core.dll") elif (platform.system() == 'Darwin'): libamcl_wcc_FP256BN = ffi.dlopen("libamcl_wcc_FP256BN.dylib") libamcl_core = ffi.dlopen("libamcl_core.dylib") else: libamcl_wcc_FP256BN = ffi.dlopen("libamcl_wcc_FP256BN.so") libamcl_core = ffi.dlopen("libamcl_core.so") libamcl_core.main() ``` It won't work, as there is no link between rom.c and `libamcl_core`. I should create a .so file from the rom.c, right? I have no knowledge in cffi and will learn how to use it. But a little help would be great ;) Also is it possible to simply export constant from a C code for importing it after from python? Thanks
