static Windows build

[89z]

Using this program:

import stdio = std.stdio;

void main() {
   stdio.writeln("hello world");
}

and this command:

ldc2 app.d

I do not get a static build. Namely, the file vcruntime140.dll is required. So I tried this:

ldc2 -static app.d

same result. It seems LDC includes the static library:

    Directory: D:\ldc2\lib\mingw

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----        2022-07-20  1:10 PM          32542 vcruntime140.lib

so it would appear it should be possible to do what I am trying to do.

You'll need an MSVC++ installation for that; then linking the MSVCRT statically is the default behavior (except for DLLs). See https://github.com/ldc-developers/ldc/blob/master/packaging/README.txt#L10-L23.

I dont understand. If LDC has its own linker, and also includes the static library needed, why cant LDC just link the static library?

[kinke]

It's a custom tiny CRT skeleton, based on the MSVC DLLs. If you really want to know more details, see https://github.com/ldc-developers/mingw-w64-libs (where the vcruntime140.lib is from).

OK fair enough, but it seems you could at least make the process simpler, for people who are in this position. For example, I dont see any links for people who want to download the Redistributable. Including that in the Readme or similar would be helpful to Windows users:

PRs are welcome. - Not sure what position you are talking about - I thought you wanted to link statically, that requires an VS/Build tools installation as mentioned in the readme. The redistributable only allows running the built stuff linked without VS (and AFAIK, comes with every non-ancient Windows).

right. Hopefully you understand, that Visual Studio is a giant bloated dependency. So given that, I would rather just deal with the DLL requirement.

I am running Windows 10, and it is not preinstalled. I checked the C:\Windows\System32 folder. If its in another folder, I can check that, but I dont know where else it would be.

Oh okay, thx - then it's just the UCRT OS component that is installed, but not the VC++ 2015+ runtime itself. - Thx for the PR.

[89z]

Can you change LDC such that, the built programs require UCRT instead of VC++ 2015+ runtime?

[kinke]

Nope, it's e.g. required for exception handling (it's MSVC++ compatible).
