预览:尝试静态链接 VS9 Express 时出现链接错误

我正在尝试基于 Poco::Process 在 Visual Studio 2008 Express 中编译一个简单的应用程序。但我遇到链接错误。

这是我配置为控制台应用程序的简单代码:

#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

并且我正在链接:

PocoFoundationmt.lib

定义了多线程调试 DLL (/MDd),但我收到此链接错误:

Preview: Linking Error when trying static linking VS9 express

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

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;
}

I added the preprocess flags:

Foundation_EXPORTS
POCO_STATIC
PCRE_STATIC

And I'm linking with:

PocoFoundationmt.lib

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

确保针对相同的 C 运行时(静态/动态、调试/发布、多线程)构建 Poco 库和项目。

Make sure that you build both the Poco libs and your project against the same C runtime (static/dynamic, debug/release, multithreaded).

不…忘初心2024-11-14 14:53:34

您正在使用的库“PocoFoundationmt.lib”是使用“release static”模式构建的。
从您运行的项目来看,您需要库的调试版本,该版本应该是“PocoFoundationmtd.lib”。

从错误日志中可以看出,链接存在冲突。也就是说,您说编译器运行时库是 MDd,但您正在链接到发行版库。确保在 ProjectProperties->Linker 中您没有链接到任何其他库,并且链接到“PocoFoundationmtd.lib。确保在项目顶部(运行按钮附近)选择“调试”而不是“发布”。同时定义POCO_STATIC

The library "PocoFoundationmt.lib" which you are using is built with "release static" mode.
From the project you ran looks like you need debug version of library which should be "PocoFoundationmtd.lib".

As you can see from the error log there is a conflict in linking. That is you said compiler the runtime-library is MDd, but you are linking to a release version library. Make sure in your ProjectProperties->Linker you are not linking to anyother libraries and do link to "PocoFoundationmtd.lib". Make sure to choose "Debug" instead of "Release" at top(near run button) of your project.Also Define POCO_STATIC.

我刚刚这样做了,正如 Chadwick 提到的,您不需要 Foundation_EXPORTS 预处理器标志。

另外,如果将附加lib目录设置为poco lib,则不需要指定dll的类型,即MT、Debug等。

您只需要POCO_STATIC作为预处理器标志。

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

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.

You only need POCO_STATIC as the preprocessor flag.
