Preview: Linking Error when trying static linking VS9 express

我试图在visual studio 2008 express中编译一个简单的应用程序基于 Poco :: Process 。

I'm trying to compile a simple application in visual studio 2008 express based on Poco::Process. But I'm getting linking errors.

这是我的简单代码配置为控制台应用程序：

Here is my simple code configured as console application:

#include "Poco/Foundation.h"
#include "Poco/Process.h"
#include "Poco/Pipe.h"
#include "Poco/PipeStream.h"
using Poco::Process;
using Poco::ProcessHandle;
using Poco::Pipe;
using Poco::PipeInputStream;
using Poco::PipeOutputStream;

int main(int argc, char** argv)
{
    std::string cmd = "hostname";
    std::vector<std::string> args;
    args.push_back("--help");

    ProcessHandle ph = Process::launch(cmd, args);
    int rc = ph.wait();

   return 0;
}

我添加了预处理标志：

Foundation_EXPORTS
POCO_STATIC
PCRE_STATIC

$ b b

我正与以下链接：

And I'm linking with:

PocoFoundationmt.lib

定义了多线程调试DLL（/ MDd），但我收到此链接错误：

with Multi-threaded Debug DLL (/MDd) defined, but I'm getting this linking error:

感谢您的帮助

What im doing wrong here ?
Thanks for helping

推荐答案

正如Chadwick所说， Foundation_EXPORTS预处理程序标志。

I just did this, as Chadwick mentioned, you don't need the Foundation_EXPORTS preprocessor flag.

此外，如果将额外的lib目录设置为poco lib，则不需要指定dll的类型，即MT，Debug等

Also if you set the additional lib directory to poco lib, you don't need to specify the type of dll i.e. MT, Debug etc.

您只需要POCO_STATIC作为预处理程序标志。

You only need POCO_STATIC as the preprocessor flag.
