c++ - GPGME : Invalid crypto engine

Question

我正在尝试检查在 C++ 项目上使用 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，并且在 Windows 下运行。

更多关于命令 gpgconf 和 gpg2 工作正常，所以 GnuGP 安装良好

我将 gpgme 的调试级别设置为 9，我得到了一个错误日志:

Invalid crypto engine

编辑:这是我运行的代码:

#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;
}

已解决:

我在虚拟目录中安装了 gpg4win，我将整个目录复制到我的 bin 中。我添加了 gpgme_set_global_flag("disable-gpgconf","1") 和 gpgme_set_global_flag("gpg-name","gpgconf") BEFORE gpgme_check_version(NULL)。
现在可以用了，谢谢。
