@Frameworks Engineer I can confirm that switching to from tensorflow.keras.optimizers.legacy import Adam fixes the XLA problem, and TF 2.11 works fine. So no need to downgrade the tensorflow version. Thank you!

Command Line Tools 15.1 also works fine, no need to downgrade to beta. Thanks Glazomer for figuring this out! https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_for_Xcode_15.1/Command_Line_Tools_for_Xcode_15.1.dmg Is the latest version that works with building the game-porting-toolkit. Maybe Apple should consider CI. :-)

As of now, installation of Apple's game-porting-toolkit is again broken, regardless of CLT/Xcode versions used. The compilation fails with: /private/tmp/game-porting-toolkit-20240603-70423-h1cgr2/wine/dlls/msvcrt20/msvcrt20.c: In function 'MSVCRT20__getmainargs': /private/tmp/game-porting-toolkit-20240603-70423-h1cgr2/wine/dlls/msvcrt20/msvcrt20.c:35:5: error: implicit declaration of function '__getmainargs' [-Wimplicit-function-declaration] 35 | __getmainargs( argc, argv, envp, expand_wildcards, &new_mode ); | ^~~~~~~~~~~~~ /private/tmp/game-porting-toolkit-20240603-70423-h1cgr2/wine/dlls/msvcrt20/msvcrt20.c: In function 'MSVCRT20__wgetmainargs': /private/tmp/game-porting-toolkit-20240603-70423-h1cgr2/wine/dlls/msvcrt20/msvcrt20.c:46:5: error: implicit declaration of function '__wgetmainargs'; did you mean 'MSVCRT20__wgetmainargs'?

This requires fixing by Apple.

Installation of what is now called "Evaluation environment for Windows games 2.0 beta" (also included in Game Porting Toolkit 2 beta) is still broken, with exactly the same problems stated above. Somehow not surprising, since the homebrew formula to build the toolkit has not been updated. Workaround is to use pre-built binaries that have been built during the 'golden age', when the toolkit still did built: https://github.com/Gcenx/game-porting-toolkit/releases

Security @Apple, please flag the current Apple Homebrew formula used in the installation of the Game Porting Toolkit at https://github.com/apple/homebrew-apple/blob/main/Formula/game-porting-toolkit.rb as security risk, since it installs outdated network, encryption and security components on user's machines (e.g. openssl 1.1). It is obvious to even a cursory reviewer that this script is completely un-salvageable, and seems to be in that state for quite some time, probably for reasons beyond the scope of bug reports. However, now, This requires a complete rewrite with up-to-date dependencies and should not be part of a 2.0 release in it's current state, even at a beta stage.
