Error in release build for arm64 with dev CDM

[franciscocarodiaz]

Mac version: macOS Big Sur, 11.0.1

I'm trying to generate version release build for arm64 with dev CDM to test in my device: ../configure --ios --cpu arm64 --release --eme-impl ~/Developer/tvup/libs/widevine_prebuilt_cdm/shaka_plugin/dev_cdm.json

And this is the error message from the console:

The error log shows Exception: No 10.14+ SDK found, this means we couldn't find Xcode. We need an Xcode install. Make sure to install command-line tools too.

I have installed xcode 12.2 and last version of command-line too.

This is from the terminal:

Submodule build(6019ed9) does not support Big Sur on its find_sdk.py. It is fixed on commit bcb7c9351 but shaka-player-embedded does not compile with this version of chromium's build project.

My workaround is to patch find_sdk.py and commit changes and new submodule version to prevent the configure system to overwrite changes. Patch:

Apply and commit changes:

I can't find out any solution related to this error. Any advice?

@franciscocarodiaz the workaround as @robelor pointed out is to apply a patch into your local shaka-player-embedded git repository. Problem is that it can not get your mac SDK as the regex only expects a 10 (it used to be 10, now it is 11).

Is there any plan to fix it on the mid-long term? I did not ran the configuration with Chromium's submodule fix (bcb7c9351) but how can we help in order to fix it? It can be a problem to rely on this workaround, especially when we want to automatize this thing.

If you still have the issue, I fixed mine by doing the following: Check where my SDK path is with xcrun --show-sdk-path It should output something like /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk

then go to the folder, and just make a symbolic link: ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk ./MacOSX10.14.sdk

It's a workaround but worked for me (unless there are some unknown issues that could happen, but I didn't encounter any yet)

Note: you might need to do the same in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

Hope this helps
