Environment

• Compiler: -

To Reproduce Steps to reproduce the behavior:

1. Install vcpkg
2. Go to folder with vcpkg-configuraration.json
3. Run vcpkg activate
4. See error

Expected behavior Expected activation to succeed.

@Vitorbnc cc @BillyONeal Could you plase help look into this issue?

I just ran into the same issue on Linux arm64.

Interestingly also while trying to fetch the artifact arm:compilers/arm/arm-none-eabi-gcc 13.3.1

[BillyONeal]

vcpkg.exe / vcpkg (the binary) can't touch environment variables in the enclosing console, only the shell function can do that. People got very very confused about "vcpkg the shell function" not being the same thing as vcpkg.exe or ./vcpkg, so we recently renamed it to vcpkg-shell: https://github.com/microsoft/vcpkg-tool/pull/1442

We also changed the error message to explain that better.

@BillyONeal I couldn't find any vcpkg-shell in the vcpkg install dir and calling vcpkg-shell does not seem to work. How do you use it?

[moritzstoetter]

@BillyONeal Are you saying that following the official installation instructions here puts you into a position, where a subsequent call to vcpkg activate fails?

If so I am not surprised that "people got very confused".

[Vitorbnc]

@moritzstoetter I just double checked.

• Ran Steps [1-3] from the official instructions,
• Copy/pasted the vcpkg-configuration.json shown above.
• Called vcpkg activate, got the following output:

@FrankXie05 @BillyONeal any updates on this?

It only works using one of the 'installed' copies of vcpkg, like the one that comes with Visual Studio or the 'one liner' installer.

Hello, I have the same problem. Is there a plan to fix this on the latest version of vcpkg on Github? or should we resignate to use the one-liner iex (iwr -useb https://aka.ms/vcpkg-init.ps1) still even though it's "not recommended for CI systems"? this on Windows 10 x64 host.

My use case is trying the below command so that it works on both local or CI build systems:

vcpkg activate

With this in a vcpkg-configuration.json on the same path:

{
 "registries": [
  {
   "name": "arm",
   "kind": "artifact",
   "location": "https://artifacts.tools.arm.com/vcpkg-registry"
  }
 ],
 "requires": {
  "arm:tools/open-cmsis-pack/cmsis-toolbox": "2.4.0",
  "arm:tools/kitware/cmake": "3.28.4",
  "arm:tools/ninja-build/ninja": "1.12.0",
  "arm:compilers/arm/armclang": "6.22.0",
  "arm:compilers/arm/arm-none-eabi-gcc": "^13.2.1",
  "arm:models/arm/avh-fvp": "^11.26.11",

 }
}

Thanks!

One of the reasons the entire artifacts feature remains experimental is that it is not practically usable from the "git clone" distribution of vcpkg. The official instructions are written for people not using artifacts because that remains 99.99% of vcpkg's user base, and the 'installed' copies don't work with classic mode.

Is there a plan to fix this on the latest version of vcpkg on Github?

I'm confirming an answer with our PM folks.
