    mp_int k;
    mp_init(&k);

}

I have configured the environment.without mp_init(&k), it can be compiled. I didn't find how to use mp_int in wolfssl document

In order to use the MP API directly, you'll need to configure the library to expose them as public using the configuration define WOLFSSL_PUBLIC_MP

Here is an example: https://github.com/wolfSSL/wolfssl-examples/blob/master/ecc/ecc-params.c

  • i have configure using './configure --enable-debug --disable-shared CFLAGS="-DWOLFSSL_PUBLIC_MP" && make && sudo make install' according to the example,but it didnot work .could you please go into more detail？thank you very much – zihao wang Mar 01 '23 at 03:45
  • If you build a static lib (`--disable-shared`), then you will need to link the static lib: `gcc -o ecc-params -I/usr/local/include ecc-params.c /usr/local/lib/libwolfssl.a -lm` – Eric Blankenhorn Mar 02 '23 at 14:19
