Building Blocks on Mac OS Sonoma with Apple Silicon chip

[NikitaYeryomin]

Question

What's your question?

I was previously able to successfully build AirSim Blocks environment on MacOS BigSur with intel chip. However, getting issues building it on new Mac with Mac OS Sonoma 14.1 and Xcode 15.2 (please see attached screenshot). There are a bunch of deprecation warnings/errors which can't be removed, e.g.
IsTriviallyCopyAssignable.h:13:17 builtin __has_trivial_assign is deprecated; use __is_trivially_assignable instead [-Werror,-Wdeprecated-builtins]

I tried to enable the -Wno-deprecated-builtins flag as shown on the screenshot, but it still does not help.
Also tried to follow the workaround described here: https://forums.unrealengine.com/t/wdeprecated-builtins-error-when-trying-to-build-ue4-on-xcode-15-0-1/1404880/3
But Xcode 13.4.1 is crashing when launched on Sonoma unfortuntely.

Kindly looking for an advice.

Same issue here... seems like we need Xcode 13 for building the engine.
I tried to build with Xcode 14 with Project Format "Xcode 13 - compatible" but I got the same problem.

Did you find a solution?

Nope, switched to my old mac for now, but definitely it's a huge issue.

Ok, on my side I was finally able to build Blocks environment on Sonoma using Colosseum and XCode 14.3.1.

Great, can you share some details?

@nikita-noteunlimited I just got Colosseum running on a M1/Sonoma/XCode 15.2 with the following steps

1. Fresh install of Colosseum and Unreal 5.2 (set as current)
2. In Colosseum, update setup.sh and build.sh to use llvm 13 (not 8)
3. Update setup.sh to add `-DCMAKE_OSX_ARCHITECTURES=x86_64` to CMAKE_FLAGS
4. After opening the XCode Workspace, in Blocks and blocks_build > Build Settings > Search for arm64
  - Update all values to x86_64
5. XCode Top menu > Product > Destinations > Destination Architectures > Enable "Show both"
6. Build using "My Mac (Rosetta)"
