c++ - 适用于 Windows 的 Linux mingw32 sfml 交叉编译 - 缺少 dll 文件

Question

我正在按以下方式编译我的 C++ 项目:

/usr/bin/i686-w64-mingw32-g++ -g -std=c++0x -Wall -I /home/bluszcz/dev/win64/SFML-2.1/include -L /home/bluszcz/dev/win64/SFML-2.1/lib -static-libgcc -static-libstdc++ -static -O4 -c src/game.cpp -o src/game.a -lsfml-graphics -lsfml-window -lsfml-system -lsfml-audio

但是，当我尝试运行我的 exe 文件时，我收到有关缺少 DLL 文件的错误消息:

bluszcz@zendo ~/dev/win32/builds/magicwizard $ wine mw.exe 
err:module:import_dll Library libgcc_s_dw2-1.dll (which is needed by L"Z:\\home\\bluszcz\\dev\\win32\\builds\\magicwizard\\sfml-system-2.dll") not found
err:module:import_dll Library libgcc_s_sjlj-1.dll (which is needed by L"Z:\\home\\bluszcz\\dev\\win32\\builds\\magicwizard\\libstdc++-6.dll") not found

err:module:import_dll Library libstdc++-6.dll (which is needed by L"Z:\\home\\bluszcz\\dev\\win32\\builds\\magicwizard\\sfml-audio-2.dll") not found

我已经使用 static 选项进行了编译 - 那么为什么它要求 libgcc_s_dw2-1.dll 例如？

另外，我在那里复制了一些文件，但应用程序仍然看不到它们。

bluszcz@zendo ~/dev/win32/builds/magicwizard $ ls *dll
libsndfile-1.dll  sfml-audio-2.dll     sfml-graphics-d-2.dll  sfml-system-2.dll    sfml-window-d-2.dll
libstdc++-6.dll   sfml-audio-d-2.dll   sfml-network-2.dll     sfml-system-d-2.dll
openal32.dll      sfml-graphics-2.dll  sfml-network-d-2.dll   sfml-window-2.dll
bluszcz@zendo ~/dev/win32/builds/magicwizard $

还有一些文件，例如 libgcc_s_dw2-1.dll，根本不存在于我的文件系统中...

总结:

1. 为什么我的应用程序看不到丢失的文件？
2. 如何用mingw32静态编译？
3. 如何获取丢失的文件？

我使用这个版本的 sfml 库来编译它:http://www.sfml-dev.org/download/sfml/2.1/SFML-2.1-windows-gcc-4.7-mingw-32bits.zip

在用 wine 运行你的程序之前，可以简单地将丢失的 dll 添加到你的 WINEPATH，即

export WINEPATH="/usr/x86_64-w64-mingw32/lib;/usr/lib/gcc/x86_64-w64-mingw32/7.3-posix"

!请注意，根据您使用的 mingw 版本，您的路径可能会略有不同。
