Cannot run simulator on M1 Mac

[mahenzon]

I built XCode project using bazel (point 6 at README), trying to build the app and run it in the simulator, but getting this error:

In cc_toolchain_suite rule @local_config_cc//:toolchain: cc_toolchain_suite '@local_config_cc//:toolchain' does not contain a toolchain for cpu 'ios_sim_arm64'

I think it's related to this line

Telegram-iOS/build-system/Make/ProjectGeneration.py

Line 149 in 72633df

'\'--cpu=ios_arm64\'.replace(\'ios_arm64\', \'ios_sim_arm64\' if os.environ.get(\'EFFECTIVE_PLATFORM_NAME\') '

ios_sim_arm64

There's some patch containing ios_sim_arm64, but I'm not sure how to apply it

did you test it running on M1 Mac? I see the repo is updated for arm CPU, but I cannot run it on my machine because sim is not starting

Environment

Device: Apple MacBook Pro (13-inch, M1, 2020)

macOS version: 11.1 (20C69)

Building for arm64 simulator is currently implemented is an internal branch. The patches will be published with the next release build.

[ali-fareed]

With the latest commit it's possible to build the app for arm64 simulators.
To do this a patched Bazel is required. The Bazel itself should not be older than bazelbuild/bazel@8c7e11a

After checking out Bazel apply this patch: bazelbuild/rules_apple#980 (comment) (rules_swift is already patched and points to our internal fork for now).

An x86_64 version of Bazel is still required to build Tulsi (until bazelbuild/bazel#12671 is resolved).

After that, use the following command to generate a project file:

python3 build-system/Make/Make.py \
	--bazel="$HOME/bazel/bazel" \
	--cacheDir="$HOME/build/telegram/bazel-cache" \
	--overrideBazelVersion \
	generateProject \
	--bazel_x86_64=$HOME/bazel/bazel_x86_64 \
	--configurationPath="$HOME/telegram-configuration" \
	 --disableExtensions

tried to build bazel for darwin_arm64, but getting an error, described it here bazelbuild/bazel#12900 (comment)

but if you succeeded building bazel for arm and generating project, maybe you could help me with this? my steps were:

• clone bazel
• apply patch
• build bazel for arm using bazel for x86 (this ends up with an error)

UPD: this is solved: bazelbuild/bazel#12900 (comment)

Full list of steps for building TG:

• Download bazel 4.0.0 curl -O -L https://github.com/bazelbuild/bazel/releases/download/4.0.0/bazel-4.0.0-darwin-x86_64 (or there'll be a newer version). I downloaded it to ~/bazel-dist-4.0.0
• mv bazel-4.0.0-darwin-x86_64 bazel
• chmod +x bazel
• download bazel source (git clone https://github.com/bazelbuild/bazel.git or whatever). It should contain this commit bazelbuild/bazel@8c7e11a
• do the patches you need: download https://gist.github.com/indragiek/e14162c0098d97ee976bceae9441f04d (it's from this comment Missing support for iPhoneSimulator platform on arm64 bazelbuild/rules_apple#980 (comment))
• go to bazel source directory, run git apply ~/patches/ios_sim_arm64.patch
• build new bazel from source using bazel 4.0.0 ~/bazel-dist-4.0.0/bazel build --cpu=darwin_arm64 //src:bazel

Your build will be in bazel-bin/src/bazel. Copy it where you need it and run chmod +x bazel

Note that this build's version will be no_version:

➜ ./bazel --version
bazel no_version

So you'll need to use flag --overrideBazelVersion. Also, Xcode version changed too already, so the full command for me was:

python3 build-system/Make/Make.py \
    --overrideXcodeVersion --overrideBazelVersion \
    --bazel="$HOME/bazel-arm/bazel" \
    --cacheDir="$HOME/telegram-bazel-cache" \
    generateProject \
    --bazel_x86_64="$HOME/bazel-dist/bazel"\
    --configurationPath="$HOME/telegram-configuration" \
    --disableExtensions \
    --disableProvisioningProfiles

Also note that --bazel uses new arm version, but --bazel_x86_64 is still that old x86 v3.7.0

And this time simulator can be run!

I would recommend to build Bazel in release mode by adding -c opt:

~/bazel-dist-4.0.0/bazel build --cpu=darwin_arm64 -c opt //src:bazel

I have M1 Macbook and I'm trying to build this project using instructions that is provided here but I'm getting following error.

Any help is appreciated.
