openssl编程，出错

ruger

openssl版本：openssl-0.9.8b-8，我编了一个小程序用来将根CA的证书添加到自己的信息的证书库中，参考了http://www.ibm.com/developerworks/cn/linux/l-openssl.html，编译的时候没错，运行时出现段错误源码如下：



#include "openssl/bio.h"
#include "openssl/ssl.h"
#include "openssl/err.h"
void main()
{
/* Initializing OpenSSL */
SSL_load_error_strings();
ERR_load_BIO_strings();
OpenSSL_add_all_algorithms();
SSL_CTX *ctx = SSL_CTX_new(SSLv23_server_method());
if(! SSL_CTX_load_verify_locations(ctx, "/NFS_mount/chip/project/openssl_test/server/Certificate/cacert.crt", NULL))
{
    printf("Handle failed load here!\n");
}
}

makefile如下：
downCA: downCA.c
        gcc downCA.c -lssl -o downCA
clean:
        rm  downCA



[root@localhost server]# make
gcc downCA.c -lssl -o downCA
downCA.c: 在函数 ‘main’ 中：
downCA.c:4: 警告：‘main’ 的返回类型不是 ‘int’
警告但没报错运行downCA
./downCA
[root@localhost server]# ./downCA
段错误


有经验的兄弟帮帮忙阿～

参考了http://www.ibm.com/developerworks/cn/linux/l-openssl.html的作者的handshake.c（http://www.kennethballard.com/developerWorks/sslhandshake.c）源码一样编译没问题，但是运行的时候出错，怀疑我的架构和内核了

通过修改makefile：

downCA: downCA.c
        gcc downCA.c -lssl -static -o downCA
clean:
        rm  downCA

出现了一大堆错误：

这是否说明是库本身的问题？libssl.so?libssl.a
