Quickpost: Compiling DLLs with MinGW on Windows

Filed under: Quickpost — Didier Stevens @ 0:00

MinGW is not only available on Kali, of course, but also on Windows. Compiling a DLL is very similar.

MinGW is installed in folder C:\msys64 on my machine.

 

To compile 64-bit executables, you need to start the 64-bit shell first: launch C:\msys64\mingw64.exe

Then you can compile the DLL:

gcc -shared -o DemoDll-x64.dll DemoDll.cpp

For 32-bit executables, it’s the 32-bit shell: launch C:\msys64\mingw32.exe

Then you can compile the DLL:

gcc -shared -o DemoDll-x86.dll DemoDll.cpp

 

It’s also possible to start the shell and compile from a BAT file:

call C:\msys64\msys2_shell.cmd -mingw64 -here -c "gcc -shared -o DemoDll-x64.dll DemoDll.cpp"
call C:\msys64\msys2_shell.cmd -mingw32 -here -c "gcc -shared -o DemoDll-x86.dll DemoDll.cpp"
