Please note when compiling on Win64, you need to explicitly list -Lgdi32.lib -Luser32.lib on the build command. If you want the Windows subsystem too, use -L/subsystem:windows -L/entry:mainCRTStartup. If using ldc instead of dmd, use -L/entry:wmainCRTStartup instead of mainCRTStartup; note the "w". see some deets i wrote here http://arsd-official.dpldocs.info/arsd.simpledisplay.html#installation-instructions

Did you try 2.099 too? Because the default build mode for 32bit was changed to MS-COFF and it smells a litte bit that you have used OMF before. MS-COFF format inserts the reference to the C-runtime library automatically. Try the -m32omf switch.

Try the -m32omf switch. I tried compiling now on x64 without console using -L/SUBSYSTEM:windows user32.lib -L/entry:mainCRTStartup -m64 and it doesn't work. It compiles, but the program does not run afterwards. I also tried to add -m32omf But in this case the compilation error. How to solve this?

There is no support for OMF for x64, 64bit build is always MS-COFF. If you specify -m64 you will generate x64 MS-COFF files. If you specify -m32mscoff you will generate x86 32bit MS-COFF files. If you specify -m32omf you will generate x86 32bit OMF files. Maybe you need to clear your object files (if any) for a clean build. If you tell the linker to entry on `mainCRTStartup`, it is expected to use that function from a C-runtime linked. As the compiler is free to select a library, this is the possible error source. Try different options for `-mscrtlib=libname` switch. What do you mean by not running? Does it return an error code? (please start it in some debugger)
