Question

我正在以下列方式编译我的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

然而，当我尝试运行我的exe文件时，我得到关于丢失dll文件的错误：

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 libwinpthread-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

然而 1 ，我已使用静态选项进行编译 - 那么为什么要求 libgcc_s_dw2-1.dll 呢？

然而 2 ，我在那里复制了一些文件，应用程序仍然没有看到它们。

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 $

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

我有三个问题：

为什么我的应用程序看不到丢失的文件？
如何使用mingw32以静态方式编译？
如何丢失文件？

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

Answer 1

Answering only the last of the three question:

About the standards libraries, it worked for me to copy them from the mingw folder:

cp /usr/lib/gcc/i686-w64-mingw32/5.3-win32/libstdc++-6.dll ./

However, when I copied from the wrong directory according to my build (e.g. /usr/lib/gcc/x86_64-w64-mingw32/5.3-posix/libstdc++-6.dll) I still had the same error while the file with the exact same name was here.

Answer 2

安装mingw64-gcc和mingw64-gcc-g++之后在我的Fedora 26上：

[leo@pc]$ locate libgcc_s_seh-1.dll
/usr/x86_64-w64-mingw32/sys-root/mingw/bin/libgcc_s_seh-1.dll
[leo@pc]$ locate libstdc++-6.dll
/usr/x86_64-w64-mingw32/sys-root/mingw/bin/libstdc++-6.dll
[leo@pc]$

如果我复制dll并使用生成的a.out.exe运行wine，则可以正常工作。

Answer 3

您的应用程序可能没有看到文件，因为它的配置是这样的，并且您不需要在命令中添加-static之类的标签。

要编译静态库，必须添加 -s ，例如-lsfml-window-s -lsfml-system-s

libgcc_s_dw2-1.dll 位于最新MinGW releases上的 bin 文件夹中。

如果缺少dll，则可能是版本不兼容。

Answer 4

丢失的dll可以简单地添加到WINEPATH中，然后再用wine运行程序，即

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

！请注意，根据所使用的mingw版本，您的路径可能会略有不同。
