Linux mingw32 sfml cross-compilation for windows - missing dll files

Question

I am compiling my C ++ project as follows:

/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 

However, when I try to run my exe file, I get an error message about missing DLL files:

 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-system-2.dll") not found err:module:import_dll Library sfml-system-2.dll (which is needed by L"Z:\\home\\bluszcz\\dev\\win32\\builds\\magicwizard\\sfml-audio-2.dll") not found err:module:import_dll Library libgcc_s_dw2-1.dll (which is needed by L"Z:\\home\\bluszcz\\dev\\win32\\builds\\magicwizard\\sfml-audio-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 

I compiled using static parameters - so why does it ask for libgcc_s_dw2-1.dll, for example?

I also copied several files there, but the application still does not see them.

 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 $ 

And some files, such as libgcc_s_dw2-1.dll , do not exist at all on my file system ...

To sum up:

1. Why doesn't my application see missing files?
2. How to compile in a static way with mingw32?
3. How to get the missing files?

I use this version of the sfml library to compile it: 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 three questions:

In the standard libraries, I managed to copy them from the mingw folder:

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

However, when I copied 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 at the time like a file with the same name was here.

Answer 2

On my Fedora 26 after installing mingw64-gcc and mingw64-gcc-g++ :

 [ 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 ]$ 

If I copy the dll and run the wine with the generated a.out.exe file, it works.

Perhaps your application does not see the files, because it is configured in this way, and you do not need to add tags like -static to the command.

To compile static libraries you must add -s , for example -lsfml-window-s -lsfml-system-s

libgcc_s_dw2-1.dll is located in the bin folder in recent MinGW releases .

If DLLs are missing, version incompatibility is possible.
