serve-d Failed to install serve-d on MacOS M1

macOS Monterey, M1, using LDC - the LLVM D compiler (1.27.1) for ARM64. Running VSCode results in the following error below

Installing into /Users/pavels/.vscode/extensions/webfreak.code-d-0.23.0/bin

Note: switching to 'v0.7.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at f10a352 bump to 0.7.0 (stable)

> /usr/local/bin/dub build --compiler=/usr/local/bin/rdmd
Failed to invoke the compiler /usr/local/bin/rdmd to determine the build platform: rdmd build 20210814
Usage: rdmd [RDMD AND DMD OPTIONS]... program [PROGRAM OPTIONS]...
Builds (with dependents) and runs a D program.
Example: rdmd -release myprog --myprogparm 5

Any option to be passed to the compiler must occur before the program name. In
addition to compiler options, rdmd recognizes the following options:
  --build-only       just build the executable, don't run it
  --chatty           write compiler commands to stdout before executing them
  --compiler=comp    use the specified compiler (e.g. gdmd) instead of ldmd2
  --dry-run          do not compile, just show what commands would be run
                      (implies --chatty)
  --eval=code        evaluate code as in perl -e (multiple --eval allowed)
  --exclude=package  exclude a package from the build (multiple --exclude allowed)
  --include=package  negate --exclude or a standard package (std, etc, core)
  --extra-file=file  include an extra source or object in the compilation
                     (multiple --extra-file allowed)
  --force            force a rebuild even if apparently not necessary
  --help             this message
  --loop=code        like eval, but wraps code in "foreach (line; stdin.byLine()) { ... }"
  --main             add a stub main program to the mix (e.g. for unittesting)
  --makedepend       print dependencies in makefile format and exit
                     (needs dmd's option `-of` to be present)
  --makedepfile=file print dependencies in makefile format to file and continue
                     (needs dmd's option `-of` to be present)
  --man              open web browser on manual page
  --shebang          rdmd is in a shebang line (put as first argument)
  --tmpdir           set an alternative temporary directory

Option -o- currently not supported by rdmd

what did code-d detect as compiler? it seems to try using rdmd to build serve-d as compiler (not allowed, only allowed to use dmd, ldc or gdc)

once supported by github actions I could also distribute prebuilt arm packages for linux and mac which would be picked up automatically without the need to update code-d

Looks like it tries to use rdmd in order to "determine the build platform". If I remove rdmd from /usr/local/bin, it fails to install

So, the issue is that it cannot determine the build platform I guess.

can you send me your user settings (JSON)? (in the user settings at the top right you can switch to JSON mode)

## Warning for package serve-d, configuration unittest-optimized ##

The following compiler flags have been specified in the package description
file. They are handled by DUB and direct use in packages is discouraged.
Alternatively, you can set the DFLAGS environment variable to pass custom flags
to the compiler, or use one of the suggestions below:

debugInfo: Call DUB with --build=debug
optimize: Call DUB with --build=release
unittests: Call DUB with --build=unittest
