universal build for macbook not working

[Abhishek Agarwal]

Hi Team,

I have to generate Chromium x64 for intel and arm64 for apple silicon universal build. I'm able to generate single - single build for both arch and its working. Even I'm able to generate distribution dmg.

Now I need to generate universal build and I tried below args flags:

target_cpu="x64"

target_os="mac"

mac_universal_binary=true

It generated only for x64 and working only in arm. I need help to generate universal build for distribution.

Thanks!

To create an universal binary, build once for arm64 and then in a different build dir for x64, and then follow https://chromium.googlesource.com/chromium/src/+/main/docs/mac_arm64.md#universal-builds

Hi Nico,

Thanks for your information!

I've made the fresh builds and it worked. Post that I'm able to make signed distribution dmg as well.

We are using widevine through component updater. Post widevine component update. When I checked "https://integration.widevine.com/player" its showing "PLATFORM_TEMPERED". In the working scenario it should be showing "PLATFORM_SECURE_STORAGE_SOFTWARE_VERIFIED".

Do you aware of it and let me know how to proceed from here?

[Abhishek Agarwal]

Yes, I followed in the mentioned document. It worked post fresh build for both architecture. Now I'm encountering different problem with widevine.

Hi Nico,

Thanks for your quick information!

After fresh build for both architecture it worked. I'm able to make distribution dmg as well.

Post installation of distribution dmg, widevine via component updater is not working and showing "PLATFORM_TEMPERED". 

Do you know and kindly help how to proceed further from here?

I don't know much about widevine. I'd recommend starting a new thread with a new subject so that people who might know about it will see it :)

Sure, thanks for letting me know.
