GPGME :无效密码引擎

Question

我试图在C++项目中检查使用gpgme，但是当我尝试访问OpenPGP引擎时

我已经在我的电脑上安装了GnuPG，而且我正在windows下运行。

更详细的命令gpgconf和gpg2工作正常，所以GnuGP安装得很好。

我将gpgme的调试级别设置为9，得到了一个错误，这是日志：

Invalid crypto engine

编辑:下面是我运行的代码：

#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;
}

Answer 1

已解决：

我在一个虚拟目录中安装了gpg4win，在我的文件夹中复制了整个目录。我把gpgme_set_global_flag("disable-gpgconf","1")和gpgme_set_global_flag("gpg-name","gpgconf") 加在 gpgme_check_version(NULL)之前。

现在起作用了，谢谢。
