在VC++ MFC应用程序中用QuickFIX实现

Question

我使用的是VC++ MFC 64位应用程序的quickfix，它工作得很好.现在我想使用ThreadedSSLSocketAcceptor，我已经完成了以下操作：

1. 下载预编译openssl-1.0.2l-vs2015.7z md51
2. 添加了所有必需的openssl 64位头文件。
3. 定义HAVE_SSL 1
4. 将openssl 64位库链接到应用程序ssleay32MDd.lib，libeay32MDd.

不过，我仍然收到以下链接错误：

这需要任何附加的库或dll吗？

Answer 1

您需要使用SSL重新构建quickfix：

1. 取消#define HAVE_SSL 1中的src/config_windows.h
2. 调用cmake -S . -DHAVE_SSL=1 (您可能需要首先将OPENSSL_ROOT_DIR env设置为OpenSSL路径，例如set OPENSSL_ROOT_DIR=C:\openssl-1.1.0f-vs2015\)。
3. 调用msbuild quickfix.sln

然后，您应该能够构建一个示例应用程序(只需确保将src\C++\release\quickfix.lib添加到链接器设置中)：

#define HAVE_SSL 1
#include <quickfix/SSLSocketAcceptor.h>

int main()
{
    FIX::NullApplication app{};
    FIX::MemoryStoreFactory factory{};
    FIX::SessionSettings settings{};
    FIX::SSLSocketAcceptor acceptor{ app, factory, settings };
}
