Problem with alr build / environment after with'ing gnoga

[bracke]

I'm getting an error when trying to build an app after withing gnoga (adding it as a dependency),

alr init --bin mytestapp
cd mytestapp
alr build
--> builds successfull

alr with gnoga
alr build
-->
error: Trying to set an already defined environment variable:
error: Target_OS is already defined as 'Linux' but new value is 'auto'

Is this something I should report to the Gnoga project or is this Alire related?

Output from alr version:

Thanks for the report. This is indeed a mistake in the metadata of both gnoga and simple_components, that should not set these variables.

There's currently no easy way to override a variable from the root project. What you can do until these releases are fixed is alr get e.g. simple_components, tweak its alire.toml, and pin to these sources from your project so there's no conflict.

@mosteo Thank you for the quick response.

I have opened an issue on the Gnoga project:
Blady-Com/gnoga#10
