Compiling EiffelStudio fails after a change in the Github repository

[Thomas Goering]

Hi,

After a change in the EiffelStudio Github repository my local build of EiffelStudio fails. It started after I pulled the latest changes from the repository to my computer and I think I have found the change that causes the failure on my computer:

It is file "Src/Eiffel/eiffel/com_il_generation/Core/run-time/runtime.cs" and this is the commit:

https://github.com/EiffelSoftware/EiffelStudio/commit/099ba31d5300094cb7184511389c7263b0816613

With this commit some "return true;" and "return false;" statements in file runtime.cs were change to "return RuntimeInformation.IsOSPlatform(OSPlatform.Windows);" and corresponding.

When I compile using "geant prepare" I get these errors:

Stop.

I marked some of the errors in bold. Basically it says "The name 'RuntimeInformation' does not exist in the current context" and similar.

When I replace all lines containing "RuntimeInformation" with the lines in the previous version of the file "Src/Eiffel/eiffel/com_il_generation/Core/run-time/runtime.cs" I get no errors!

Is it a problem on my computer (Windows 11) or is something missing the current Github repository?

Thanks,

Thomas

After pulling the now-latest changes from the repository I noticed that the issue has been resolved with this commit:

https://github.com/EiffelSoftware/EiffelStudio/commit/27800797a96a20c668ba8a64c3fcb7e2f8f63539

with basically the same solution (for .NET Framework 4.7 - which I have installed) that I used as a workaround.
