我已经使用sudo apt-get install openssl-dev. 当我尝试使用Netbeans它编译它时，会出现以下错误。我该如何解决这个问题？

g++     -lssl -o dist/Debug/GNU-Linux-x86/cppapplication_2 build/Debug/GNU-Linux-x86/main.o -L/home/sercan/Desktop/openssl-0.9.8h-1-lib/lib

我的代码在这里：

#include <stdio.h>
#include <stdlib.h>
#include <openssl/pem.h>
#include <openssl/err.h>
#include <openssl/pkcs12.h>

/* Simple PKCS#12 file reader */

int main(int argc, char **argv)
{

    FILE *fp;
    EVP_PKEY *pkey;
    X509 *cert;
    STACK_OF(X509) *ca = NULL;
    PKCS12 *p12;
    int i;

    if (argc != 4) {
        fprintf(stderr, "Usage: pkread p12file password opfile\n");
        exit(1);
    }

    OpenSSL_add_all_algorithms();
    ERR_load_crypto_strings();

    if (!(fp = fopen(argv[1], "rb"))) {
        fprintf(stderr, "Error opening file %s\n", argv[1]);
        exit(1);
    }

    p12 = d2i_PKCS12_fp(fp, NULL);

    fclose(fp);

    if (!p12) {
        fprintf(stderr, "Error reading PKCS#12 file\n");
        ERR_print_errors_fp(stderr);
        exit(1);
    }

    if (!PKCS12_parse(p12, argv[2], &pkey, &cert, &ca)) {
        fprintf(stderr, "Error parsing PKCS#12 file\n");
        ERR_print_errors_fp(stderr);
        exit(1);
    }

    PKCS12_free(p12);

    if (!(fp = fopen(argv[3], "w"))) {
        fprintf(stderr, "Error opening file %s\n", argv[1]);
        exit(1);
    }

    if (pkey) {
        fprintf(fp, "***Private Key***\n");
        PEM_write_PrivateKey(fp, pkey, NULL, NULL, 0, NULL, NULL);
    }

    if (cert) {
        fprintf(fp, "***User Certificate***\n");
        PEM_write_X509_AUX(fp, cert);
    }

    if (ca && sk_X509_num(ca)) {
        fprintf(fp, "***Other Certificates***\n");
        for (i = 0; i < sk_X509_num(ca); i++)
            PEM_write_X509_AUX(fp, sk_X509_value(ca, i));
    }

    fclose(fp);

    return 0;
}

您还需要链接到 libcrypto - 添加-lcrypto到链接行，您的代码应该正确链接。

natsu:~/openssl% gcc -o test test.c -L/usr/lib -lssl -lcrypto

正确链接，同时：

natsu:~/openssl% gcc -o test test.c -L/usr/lib -lssl         
/tmp/ccvA7iNe.o: In function `main':

才不是。
