* Hi:*
*I static compile opensslv1.1.1 on Ubuntu18.04 as follow :*
$./config no-shared
*and then:*
$make
$make install
*after that, I write a test.c like this:*
#include <stdio.h>
#include <string.h>
#include <time.h>
#include <openssl/err.h>
#include <openssl/bn.h>
#include <openssl/rsa.h>
#include <openssl/pem.h>
#include <openssl/crypto.h>
#include <ctype.h>
#include <stdlib.h>
#include <unistd.h>
int generate_key(int bits, int count)
{
int ret = 0;
RSA *r = NULL;
BIGNUM *bne = NULL;
unsigned long e = RSA_F4;
fprintf(stdout, "id;n;e;p;q;d;t\n");
for (int i = 0; i < count; i++) {
bne = BN_new();
ret = BN_set_word(bne,e);
r = RSA_new();
ret = RSA_generate_key_ex(r, bits, bne, NULL);
}
return (ret == 1);
}
// added main function
int main (){
printf("Hello\n");
return 0;
}
*and static compile it as follow:*
$gcc -static -o test test.c -lssl -lcrypto -ldl -pthread

*when i exec the test:*
$./test

*Use gdb for debug:*

*So, how did i use openssl for static link?*
