Bug 10229 – RDMD: --compiler flag doesn't work properly when not adding .exe on win32

While trying to use "dmd_msc" as the compiler (DMD built with Visual Studio): test.d: ----- module test; import std.stdio; unittest { assert(0); } void main() { writeln("here"); } ----- $ rdmd --chatty --force -unittest --compiler=dmd_msc test.d It then spits out these and just exits: ----- stat C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd stat C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-1648EF87D7393B7077F5EA9F7EC96F7F "dmd_msc" "-v" "-o-" "test.d" "-I." read C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-1648EF87D7393B7077F5EA9F7EC96F7F\rdmd.deps stat C:\Windows\System32\dmd_msc stat F:\path\dmd_msc stat C:\Program Files (x86)\Windows Resource Kits\Tools\dmd_msc stat %SystemRoot%\system32\dmd_msc stat %SystemRoot%\dmd_msc stat %SystemRoot%\System32\Wbem\dmd_msc stat %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\dmd_msc stat C:\Program Files\Microsoft Windows Performance Toolkit\dmd_msc stat C:\Program Files (x86)\Gtk-Runtime\bin\dmd_msc stat C:\Program Files (x86)\GtkSharp\2.12\bin\dmd_msc stat C:\Program Files (x86)\dub\dmd_msc stat C:\dmd-git\dmd2\src\dmd_msc stat C:\Program Files (x86)\FLAC\dmd_msc stat C:\dmd-git\dmd2\windows\bin\dmd_msc stat C:\DMD\dmd2\windows\bin\dmd_msc stat C:\dm\bin\dmd_msc stat C:\MinGW\bin\dmd_msc stat D:\Apps\Console2\dmd_msc stat D:\Program Files\GnuWin32\bin\dmd_msc stat C:\Program Files (x86)\IrfanView\dmd_msc ----- But if I add an .exe extension, it will work: $ rdmd --chatty --force --compiler=dmd_msc.exe test.d ----- stat C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd stat C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-4480389CE04A3C961E500FA1600300A5 "dmd_msc.exe" "-unittest" "-v" "-o-" "test.d" "-I." read C:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-4480389CE04A3C961E500FA1600300A5\rdmd.dep s stat C:\Windows\System32\dmd_msc.exe stat F:\path\dmd_msc.exe stat C:\Program Files (x86)\Windows Resource Kits\Tools\dmd_msc.exe stat %SystemRoot%\system32\dmd_msc.exe stat %SystemRoot%\dmd_msc.exe stat %SystemRoot%\System32\Wbem\dmd_msc.exe stat %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\dmd_msc.exe stat C:\Program Files\Microsoft Windows Performance Toolkit\dmd_msc.exe stat C:\Program Files (x86)\Gtk-Runtime\bin\dmd_msc.exe stat C:\Program Files (x86)\GtkSharp\2.12\bin\dmd_msc.exe stat C:\Program Files (x86)\dub\dmd_msc.exe stat C:\dmd-git\dmd2\src\dmd_msc.exe stat C:\Program Files (x86)\FLAC\dmd_msc.exe stat C:\dmd-git\dmd2\windows\bin\dmd_msc.exe "dmd_msc.exe" "-unittest" "-ofC:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-4480389CE04A3C96 1E500FA1600300A5\test.exe" "-odC:\Users\ADMINI~1\AppData\Local\Temp\.rdmd\rdmd-test.d-4480389CE04A3C9 61E500FA1600300A5\objs" "-I."

Could your rdmd be out of date? Sounds like this should have fixed the issue: https://github.com/D-Programming-Language/tools/commit/d259d8dc1ebf7376b20a69461ad87e578611480f
