Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Hi! This is the friendly automated conda-forge-webservice.

I tried to re-render for you, but it looks like there was nothing to do.

[jschueller]

does anyone know how to deal with this error ?

PCbuild\pythoncore.vcxproj(42,3): error MSB4019: 
The imported project "D:\Microsoft.Cpp.Default.props" was not found. 
Confirm that the path in the <Import> declaration is correct, 
and that the file exists on disk.

On OSX, it failed with the same issue I had locally (conda-forge/pyside2-feedstock#46 (comment)):
undef: ___llvm_profile_runtime

Not exactly sure what this is about, but it has to do with enabling profile guided optimization in clang. This is why I had to set

DEBUG_C:
- yes

locally to get python3.6 to compile with clang 9...

undef: ___llvm_profile_runtime is because of an issue in our compiler-rt package which was fixed recently.

[jschueller]

@isuruf now on windows I get:
pythoncore.vcxproj(42,3): error MSB4019: The imported project "D:\Microsoft.Cpp.Default.props" was not found.

[jschueller]

@isuruf it seems to go much further on appveyor, unfortunately it timeouts
