I cannot use function crypto_core_ed25519_random in iOS, but I can use other functions like sodium_init

[wangfenghappy]

#import "sodium.h"
#import "crypto_core_ed25519.h"

static void ecdh(void){
int res = sodium_init();
if (res != -1){
NSLog(@"sodium_init success!");
}
//
unsigned char * kd = calloc(32, sizeof(unsigned char));
crypto_core_ed25519_random(kd);
NSLog(@"sodium_init %s", kd);
}

Undefined symbols for architecture x86_64:

#import "crypto_core_ed25519.h"

You should just import sodium.h

How did you build the library? Is it a full build or a minimal build?
