[bug] can't build openssl from conan in windows

[omayaro]

Describe the bug

Environment details:
OS: windows
compiler: clang
conan version: conan2
openssl version: 3.0.14

description:
trying to build open ssl but getting failed with "clang: error: unknown argument: '-MDd'". this works on Mac OS. I'm trying to build this on windows now but it fails. not sure how to fix this issue.

can someone get me help?

detail error logs are

How to reproduce it

No response

Hi @omayaro

Thanks for your feedback.

Recipes and packages from ConanCenter are built and tested in Windows with msvc compiler, but not with clang. Consequently, support for Clang compiler in Windows might vary, so this might not be a Conan issue per se, but a recipe limitation. If you can, I'd recommend using msvc compiler in Windows for ConanCenter packages.

I'll try to have a look to the issue, can you please provide:

• The full profile that you are using. clang is not the default compiler, so it might need definitions as [buildenv] and/or compiler_excutables conf
• The command that you are using
• Which exact Conan version (the output of conan version can be useful in general)
• The profile looks an Android one, so this might need its own configuration, like the ndk_path conf

[omayaro]

I'm not sure these are what you wanted but let me try to provide.

• compiler_executables = {
  "c": self._define_tool_var("CC", "clang"),
  "cpp": self._define_tool_var("CXX", "clang++"),
  }

• conan vesion: 2.7.1

• ndk_path: C:\Users\omayaro\AppData\Local\Android\Sdk\ndk\25.2.9519653

I'm installing openssl by conan. I missed first part. maybe you want to see those. this log is first part of logs that I attached above.
