New MacOS and Xcode update incompatible with Cmake?

Usage
1

I’ve been running code smoothly for the last few weeks up until today after my macOS updated to Sonoma 14.2.1 and Xcode to 15.2 overnight. I updated cmake using homebrew to the latest version: 3.28.1, but now I’m getting strange errors:

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=17 -DCMAKE_INSTALL_PREFIX=$MU3EPREFIX/software/install $MU3EPREFIX/software/mu3eAna

It fails with the following output:

Anyone got any ideas?

Delete your build directory and start with a fresh build.

Hi, thanks for your suggestion. I’ve tried uninstalling and reinstalling but to no avail. I’m using homebrew so I’m not sure if that’s the problem?

Please try the following minimal project, which should at least confirm whether you have a working toolchain and CMake installation:

CMakeLists.txt:

cmake_minimum_required(VERSION 3.28)
project(minimal)

This works for me with essentially the same versions of things as you.

I am using too Sonoma (14.2.1) and cmake 3.28.1. I use cmake installed with the package downloaded from cmake.org

He means the build directory. This error happens sometimes when I update macos like that too across projects.

Say I previously did

cmake -B build

For some project, then macos/xcode upgrades ad I get that error. In that same directory as before I do

rm -r build

cmake -B build

And all is well.

Hi, thanks for the reply. I’m not too familiar with cmake and only really use it to compile code that uses cmake files (I did not write them). I uninstalled cmake with homebrew and tried to build from scratch and I’ve got up to make install but now it’s requesting a password and administrative privileges so I’m not really sure what’s going on. Do you perhaps know what the equivalent of this fix is for cmake installed with homebrew?

I tried this and got the following output:

Thanks for everyone’s suggestions. After hours searching Google somebody recommended trying the command:

export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)

It seemed to fix things (I think the SDK path was wrong?) although I’m getting some deprecation errors, but at least it works!
