链接错误：使用CMake在Windows上为MinGW静态构建C ++ Poco

标签： c++ windows cmake mingw poco-libraries

我想在Windows上静态构建最新的Poco C ++库完整版（仅限Poco :: Foundation和Poco :: Zip，没有样本和测试），用于MinGW（由QT Creator提供）。

首先，我从主页https://pocoproject.org/download/index.html下载并解压缩Windows版本库 它现在是版本 poco-1.7.8p3-all

现在我必须更改不同配置的MC设置而不是VS，所以我必须更改文件 $（POCO_BASE）/cmake/PocoMacros.cmake 在IF之后

if ("${CMAKE_GENERATOR}" MATCHES "Visual Studio") ... endif ()

添加行：

 get_filename_component(sdk_dir "[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Microsoft SDKs\\Windows;CurrentInstallFolder]" REALPATH)
 set(sdk_bindir "${sdk_dir}/bin")

我使用CMake命令：

cmake -G "MinGW Makefiles" -DENABLE_CRYPTO=OFF -DENABLE_NET=OFF -DENABLE_XML=OFF -DENABLE_DATA=OFF -DENABLE_MONGODB=OFF -DENABLE_PAGECOMPILER=OFF -DENABLE_PAGECOMPILER_FILE2PAGE=OFF -DENABLE_NETSSL=OFF -DPOCO_STATIC=ON -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\user\Desktop\stackPocoStatic\built

输出：

然后我运行make：

PS C:\Users\user\Desktop\stackPocoStatic\poco-1.7.8p3-all> mingw32-make.exe
[ 43%] Built target Foundation
[ 60%] Built target XML
[ 63%] Built target JSON
[ 70%] Built target Util
[ 94%] Built target Net
[100%] Built target Zip
PS C:\Users\user\Desktop\stackPocoStatic\poco-1.7.8p3-all> mingw32-make.exe install
...

它看起来没问题，所以我想编译并运行代码，例如：

#include <iostream>
#include <fstream>
#include <Poco/Zip/Compress.h>

int main( int argc, char * argv[] )
{
    std::ofstream outputZipArchive("archive.zip", std::ios::binary);

    Poco::Zip::Compress compressor( outputZipArchive, true );
    for( unsigned i = 1; i < argc; ++i )
    {
        const char * fileToZip = argv[i];
        std::cout << i << ") Adding: " << fileToZip << std::endl;
        try
        {
            compressor.addFile( fileToZip, fileToZip );
        }
        catch(const Poco::FileNotFoundException & e)
        {
            std::cerr << "Can not add file " << fileToZip << ", because: " << e.what() << std::endl;
        }
    }

    compressor.close();
    outputZipArchive.close();
}

在编译期间我看到链接错误：

collect2.exe: error: ld returned 1 exit status

有趣的是，当我运行./configure时没有选项 -DPOCO_STATIC = ON ：

cmake -G "MinGW Makefiles" -DENABLE_CRYPTO=OFF -DENABLE_NET=OFF -DENABLE_XML=OFF -DENABLE_DATA=OFF -DENABLE_MONGODB=OFF -DENABLE_PAGECOMPILER=OFF -DENABLE_PAGECOMPILER_FILE2PAGE=OFF -DENABLE_NETSSL=OFF -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\user\Desktop\stackPocoDynamic\built

然后

mingw32-make.exe && mingw32-make.exe install

然后编译：

PS C:\Users\user\Desktop> g++.exe z.cc -isystemC:\Users\user\Desktop\stackPocoDynamic\built\include -LC:\Users\user\Desk
top\stackPocoDynamic\built\lib\  -lPocoFoundation -lPocoZip

没有链接错误。当然这次我需要.dll（libPocoZip.dll和libPocoFoundation.dll）来运行代码：

 .\a.exe file.txt
 1) Adding: file.txt

我当然试过了： Static and Dynamic/Shared Linking with MinGW 的 -Wl，-Bstatic ：

PS C:\Users\user\Desktop> g++.exe -Bstatic z.cc -isystemC:\Users\user\Desktop\stackPocoStatic\built\include -LC:\Users\user\Desktop\stackPocoStatic\built\lib\  -lPocoFoundation -lPocoZip

我还尝试添加选项 -static ： Statically linking libraries in MinGW 

PS C:\Users\user\Desktop> g++.exe z.cc -static -isystemC:\Users\user\Desktop\stackPocoStatic\built\include -LC:\Users\us
er\Desktop\stackPocoStatic\built\lib\  -lPocoFoundation -lPocoZip

不幸的是，仍然存在链接错误。

在Windows上使用MSYS进行编译时，我注意到了类似的链接错误：

./configure  --static --no-tests --no-sharedlibs --omit=XML,JSON,Util,NetSSL_OpenSSL,Data,Data/SQLite,Data/ODBC,Data/MySQL,MongoDB,PageCompiler,PageCompiler/File2Page,Crypto,PDF,CppParser --config=MinGW

所以我的问题是： 是否可以在Windows上静态编译MinGW的POCO C ++库？
