GPGME:加密引擎无效 我试图在C++项目上检查GPGME，但是当我尝试访问OpenPGP引擎< /P>

我已经在我的计算机上安装了GnuPG，我正在windows下运行

更多的命令

gpgconf

和

gpg2

工作正常，因此GnuGP安装良好

我将gpgme的调试级别设置为9，但出现了一个错误，日志如下：

编辑： 以下是我运行的代码：

#include "gpgme.h"
#include <iostream>
using namespace std;

void genKey()
{
    gpgme_set_global_flag("debug","9");
    gpgme_check_version(NULL);
    gpg_error_t test = gpgme_engine_check_version(GPGME_PROTOCOL_OpenPGP);
    cout << gpgme_strerror(test) << endl;
    cout << "Engine : " << gpgme_get_dirinfo("gpg-name") << endl;
}

#包括“gpgme.h”
#包括
使用名称空间std；
void genKey（）
{
gpgme_设置_全局_标志（“调试”，“9”）；
gpgme\U检查\U版本（空）；
gpg_错误测试=gpgme_引擎检查版本（gpgme_协议OpenPGP）；
无法解决：


我在一个虚拟目录中安装了gpg4win，我在我的bin中复制了整个目录。我在
gpgme\u set\u global\u标志（“禁用gpgconf”，“1”）
和
gpgme\u set\u global\u标志（“gpg名称”，“gpgconf”）
之前添加
gpgme\u检查版本（空）

现在可以使用了，谢谢。
您的代码似乎对我有效，只是我没有在调用
gpgme\u get\u dirinfo（）
时包含该行，因为我的实现没有该功能（不确定原因）。
