Hello @alexbatashev We are aware of this issue. It happens because:

  1. Conan changed their remote repository hosting site. Fix mentioned in #117
  2. Reference-LAPACK Conan package that was maintained by a third-party, is now end-of-lifed, so whenever we try to use the Conan build process, we get the error like you mentioned in the logs.

@hgunalan Possible solutions from best to worst in my opinion:

  1. If Intel can host a custom Conan pkg remote repository, we can upload all required packages for this project to that repo and also maintain them whenever required. We know that VTune already supports Conan packages. This repo can be public or private - up to Intel to decide.
  2. Replace Conan with another package manager that has more vendor-side support instead of community-driven, but this will require us to find supported distribution channels for all currently supported backends and dependencies before landing on a final decision. Also, future integrations for other backends will be questionable, because they may or may not provide Conan packages.
  3. Remove Conan and only support CMake. With this option, we will lose the ability to automate the installation of dependencies. This will affect customers and Continuous Integration.

@alexbatashev We have decided to drop Conan package manager support. Please refer to https://github.com/oneapi-src/oneMKL/discussions/267 for more details.

The cleanup will be performed soon, and the build instructions will be updated as well.
