Anything else we should know about your project / environment?

Already tried:

reinstall Xcode-tools
set/unset force_ruby_platform
setting flags

export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
export PKG_CONFIG_PATH="/usr/local/opt/zlib/lib/pkgconfig"
export GRPC_DISABLE_THIRD_PARTY_ZLIB=1

install gem with gem install grpc -- --with-zlib-dir=/usr/local/opt/zlib

I'm having the same problem. Looks like it has something to do with Command Line Tools for Xcode 16.3, since downgrading to 16.2 fixes it.

The workaround that works for me is:

Log in with an Apple account here: https://developer.apple.com/download/all/
Download and install version 16.2 of the Command Line Tools for Xcode: https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_for_Xcode_16.2/Command_Line_Tools_for_Xcode_16.2.dmg
Try installing the gem again.

kefiriaus · 2025-04-25T16:06:00Z

@stefanwork Thank you, I also understood that Command Line Tools not compatible with zlib 1.3 that is used in grpc 1.69.0 (also in newer versions, as I've tried them all)

As I see in 1.72.0 zlib was updated to v1.3.1 but this version is not in rubygems.org yet.

I also tried some downgrade of the Command Line Tools to v15 but it did not work and I did not think that only one minor version will do the trick, thx again for sharing your way.

After three nights of trying and asking Ai and searching google I ended up with coping this compiled gem from other MacBook and its finally worked earlier today.

chadlwilson · 2025-04-25T16:57:10Z

Or better yet, avoid having to compile from source at all by installing 1.70.1 onwards where the gems are precompiled for Ruby 3.4 and should install near instantly as long (as you’re not forcing use of ‘Ruby’ platform only)

1.69 predates Ruby 3.4 so by definition the gems are not precompiled.

chadlwilson · 2025-04-25T17:00:04Z

Any fix that needs to be made here is not going to be backported to 1.69.x anyway (from what I have seen of grpc releases, although I am not a maintainer) so you’re going to have to try with newer versions anyway.

chadlwilson · 2025-04-25T17:09:50Z

As a side note, why would you want to install x64 versions of gems via Rosetta if you have an Apple Silicon M4 macbook, rather than using aarch64 gems, or trying to compile for that platform at least?

jasonpenny · 2025-04-25T17:53:39Z

I found a workaround by installing an old version of the LLVM toolchain from homebrew (https://brew.sh/):

$ brew install llvm@17

$ export PATH="$(brew --prefix llvm@17)/bin:$PATH"
$ export CC=clang
$ export CXX=clang++
$ export LDFLAGS="-L$(brew --prefix llvm@17)/lib"
$ export CPPFLAGS="-I$(brew --prefix llvm@17)/include"

$ gem install grpc --platform=ruby --version 1.69.0
Building native extensions. This could take a while...

kefiriaus · 2025-04-25T19:27:44Z

@jasonpenny Hm, also tried these steps, didn't work for me.

oleg-vinted · 2025-04-30T10:54:58Z

Here's what worked for us:

sudo rm -rf /Library/Developer/CommandLineTools
Log in with an Apple account here: https://developer.apple.com/download/all/
Download and install version 16.2 of the Command Line Tools for Xcode: https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_for_Xcode_16.2/Command_Line_Tools_for_Xcode_16.2.dmg
Reinstall the affected Ruby 3.4.x version: e.g. mise uninstall ruby@3.4.2 then mise install ruby@3.4.2
Reinstall grpc: gem install grpc -v 1.64.3 or bundle install

Notes

Not sure if step 1 is necessary, I've done this to make sure there is no trace of the old toolchain left.

Steps 2 and 3 are copied from #39363 (comment).

Reinstalling Ruby (step 4) is necessary if you've built Ruby 3.4 using the newest Command Line Tools and you get errors like this after toolchain downgrade:

Version 1.72.0 was released today and it resolves this issue for me.
