Can't generate Project on M1

[AnjeyNov]

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 do everything as described above, but I get a message

usage: Make [-h] [--verbose] --bazel path [--bazelUserRoot path] [--overrideBazelVersion] [--overrideXcodeVersion] [--bazelArguments arguments] [--cacheHost http://host:9092 | --cacheDir path]
            {clean,generateProject,build} ...
Make: error: unrecognized arguments: --bazel_x86_64=/Users/anjeynovitskiy/bazel-dist/bazel

An Intel version of Bazel is no longer required, so the --bazel_x86_64 argument was dropped.

How can i generate a project on Mac M1? None of the instructions found for me can do this (

[ali-fareed]

At which step are you getting stuck?

[AnjeyNov]

2. Clone the project from GitHub:
   git clone --recursive -j8 https://github.com/TelegramMessenger/Telegram-iOS.git
   DONE ✅

3. Download Bazel 4.0.0 to ~/bazel-arm
   DONE ✅

4. Adjust configuration parameters

Modify the values in variables.bzl - SKIP
Replace the provisioning profiles in provisioning with valid files - SKIP
Replace value "Xcode" in Telegram_iOS/versions.json to "12.5.1"

5. Create a build cache directory to speed up rebuilds
   DONE ✅

6. Build the app

Run:

python3 build-system/Make/Make.py \
    --bazel="$HOME/bazel-arm/bazel" \
    --cacheDir="$HOME/telegram-bazel-cache" \
    build \
    --configurationPath="$HOME/telegram-configuration" \
    --buildNumber=100001 \
    --configuration=release_universal;  

but I get a message:

7. Generate an Xcode project

Run:

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

I get a project with errors

to solve this error I use

but when executing the command:

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

get

usage: Make [-h] [--verbose] --bazel path [--bazelUserRoot path] [--overrideBazelVersion] [--overrideXcodeVersion] [--bazelArguments arguments]
            [--cacheHost http://host:9092 | --cacheDir path]
            {clean,generateProject,build} ...
Make: error: unrecognized arguments: --bazel_x86_64=/Users/anjeynovitskiy/bazel-dist/bazel

An Intel version of Bazel is no longer required, so the --bazel_x86_64 argument was dropped.

For anyone that has M1 Max, what I did is downloaded version 5 from here https://github.com/bazelbuild/bazel/releases/tag/5.0.0 and used that. Nothing else worked for me.
