Are there any working instructions about how to build and test dmd on Windows?

I know that there are contributing guides but I fail to successfully follow any of them: https://wiki.dlang.org/Starting_as_a_Contributor 1. Bash install script will not run under Windows. Using git bash will result in error (Command error: undefined switch '-C') 2. Digger it's not compiling 3. Tried to make my own powershell script to mimic the setup.sh behavior. I'm stuck at compilation part (below) https://wiki.dlang.org/Building_under_Windows 1. After several retries, I managed to compile DMD with make -fwin32.mak. In fact I'm not sure which is the intended makefile (the one in \dmd or the one in \dmd\src?) 2. make -fwin64.mak fails: make -fwin32.mak C=dmd\backend TK=dmd\tk ROOT=dmd\root MAKE="make" HOST_DC="dmd" MODEL=64 CC="vcbuild\msvc-dmc" LIB="vcbuild\msvc-lib" OBJ_MSVC="..\generated\windows\release\64/strtold.obj ..\generated\windows\release\64\longdouble.obj ..\generated\windows\release\64\ldfpu.obj" "OPT=" "DEBUG=-D -g -DUNITTEST" "DDEBUG=-debug -g -unittest" "DOPT=" "LFLAGS=-L/ma/co/la" ..\generated\windows\release\64\dmd.exe vcbuild\msvc-dmc -c -o..\generated\windows\release\64\newdelete.obj -Idmd\root -D -g -DUNITTEST -cpp -DTARGET_WINDOS=1 -DDM_TARGET_CPU_X86=1 dmd\root\newdelete.c "\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\cl.exe" /nologo /Ivcbuild /Idmd\root /FIwarnings.h /c /Fo..\generated\windows\release\64\newdelete.obj /Idmd\root /DDEBUG /Zi -DUNITTEST /TP ^"-DTARGET_WINDOS=1^" ^"-DDM_TARGET_CPU_X86=1^" dmd\root\newdelete.c std.process.ProcessException@std\process.d(753): Failed to spawn new process (The system cannot find the file specified.) ---------------- 0x004136E8 0x0040D98A 0x00402CDB 0x00412D67 0x00412CE9 0x00412B84 0x0040D5D7 0x758A8654 in BaseThreadInitThunk 0x77B84A77 in RtlGetAppContainerNamedObjectPath 0x77B84A47 in RtlGetAppContainerNamedObjectPath --- errorlevel 1 --- errorlevel 1 --- errorlevel 1 https://wiki.dlang.org/DMD_development 1. Downloaded GNU Make. How do I install it? What binaries are needed? 2. Installed Linux Subsystem (Debian). What next? Why do I need this? 3. All the make commands failed to execute. I suppose because make.exe is expected to be part of the GNU package. Failed to find such file in the GNU Make distribution.

Yah it's not fun. Some notes: You might need to set MSVC_CC environment variable cause it doesn't use the right format for VS path, depending on your version. https://github.com/dlang/dmd/blob/v2.079.0/src/vcbuild/msvc-dmc.d#L19 You could open a command prompt with the batch file running which will add variables used by the script. C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/vcvarsall.bat You should be able to build it now with just: make -f win64.mak reldmd When building druntime/phobos you need to pass the VCINSTALLDIR environment variable, but it has an unexpected "/" at the end of it so you need to remove it. make -f win64.mak VCDIR="%VCINSTALLDIR:~0,-1%" DMD=../dmd/src/dmd Didn't check if it works though I don't normally use batch/cmd.
