premake5: how to set runtime library to Multithreaded DLL (/MD) in vs2015

Question

kind "SharedLib"
language "C++"
defines "DLL_EXPORT"
targetname "read_cad_file"
targetextension ".arx"

I am developing using objectARX, and I want to compile my project using premake5 and vs2015. Some of the settings in the script is as the above. Under this setting, in properties->C/C++->Code Generation->Runtime Library, the runtime library is Multithreaded Debug(/MTd). I would like to ask how to change it to Multithreaded DLL (/MD) using premake5? Thanks a lot:)

You are still on the Debug configuration, switch to the Release configuration. — Hans Passant, Jun 27 '17 at 08:42

In order to change the runtime library in premake, you need to use two keywords - staticruntime and runtime.

To use /MT in premake:

staticruntime "on"
runtime "Release"

To use /MTd in premake:

staticruntime "on"
runtime "Debug"

To use /MD in premake:

staticruntime "off"
runtime "Release"

To use /MDd in premake:

staticruntime "off"
runtime "Debug"

The key you are looking for is staticruntime. While it should be off by default, you can also turn it off explicitly

As in

staticruntime "Off"

   configuration "Debug"
      buildoptions "/MDd"
   configuration "Release"
      buildoptions "/MD"
   configuration {}

Can you explain how and why these options will solve OP's problem? – oguz ismail Dec 15 '18 at 16:51

I don't know about the static or DLL versions of the runtime. But debug and release should be switchable by the runtime keyword. See:

I tried the keyword runtime before, but it doesn't work. – summer Jun 27 '17 at 08:26
Post the full premake file then. If it really "does not work" you should file a bug at the premake project. – Florian Zwoch Jun 27 '17 at 08:34
I post the full premake file in the answer below, thanks! – summer Jun 29 '17 at 08:00

So, my project isn't a shared lib, but an exe.

What I added was the following to the 'filter' section:

filter "configurations:Debug"
    architecture "x86_64"
    links {"libprotobufd"}
    defines {"DEBUG"}
    symbols "On"
    libdirs { baseLibPath .. "debug" } -- baseLibPath was defined elsewhere
    postbuildcommands {}
    debugdir "$(TargetDir)"
    flags {"staticruntime"} -- this is what worked for me

I'm not sure if that will solve your problem, but give it a go?

I'm still relatively new to premake, so take this with a grain of salt.
