`brew install --verbose openexr

There is this message from OpenEXR's build in your log:

CMake Error at cmake/CMakeLists.txt:159 (add_library):
add_library cannot create ALIAS target "OpenEXR::Config" because another
target with the same name already exists.

It's hard to tell what's going wrong here, I don't believe this is a problem we've encountered before. It is likely specific to building on your old OS and toolchain, which homebrew itself says are no longer supported:

Error: You are using macOS 11.
We (and Apple) do not provide support for this old version.
It is expected behaviour that some formulae will fail to build in this old version.

These are messages from Homebrew itself. The OpenEXR project team does not maintain Homebrew itself, nor even the Homebrew recipe for building OpenEXR.

I doubt that any of us have a way to reproduce the problem given that we don't have any OS installs that old that we can run CI on.

Recently I tried to compile OpenEXR on macOS 10.15 using Homebrew as well, and I encountered the exact same problem ("add_library cannot create ALIAS target"). Then I suspect it was due to the old version of my system. I tried compile it using my macOS 14 machine using brew reinstall openexr --build-from-source, this problem still happened. Hopefully this will help.

This issue might be related to Homebrew, not OpenEXR. You can use the command brew --version to check the version of Homebrew installed on your system. If you have the latest version, you can try downgrading Homebrew to version 4.2.18 before proceeding with the compilation and installation of OpenEXR.

OpenEXR is relying on the OLD behavior of CMake policy CMP0107, which is deprecated by definition. Homebrew inadvertently switches CMP0107 to the NEW behavior, which breaks OpenEXR, by calling cmake_minimum_required(VERSION 3.24) in ${HOMEBREW_LIBRARY}/Homebrew/cmake/trap_fetchcontent_provider.cmake.

You can restore the OLD behavior (and suppress the error) by adding the following line to OpenEXR's CMakeLists.txt:

cmake_policy(SET CMP0107 OLD)

However, realize that OpenEXR's CMakeLists.txt is apparently expecting CMake to behave in a way that it does not (and apparently never has). Calling add_library() multiple times with the same <name> but different ALIAS <target>s does not accumulate those targets under the aliased name but rather either silently overwrites(!) the alias (the OLD behavior) or raises an error (the NEW behavior).

I started a discussion of the problem at Homebrew.

Tested with the latest homebrew, confirmed that the problem no longer exists. This issue could be closed.

Hi, may I ask the latest homebrew version you used? Mine is 4.3.3. Also my OS version is Big Sur 11.7.10. Still same error showed. Thanks!

I'm also using 4.3.3 on macOS 14.5. Did you run something like brew upgrade to pull the latest commits which contain the fix for this?

Sure, I use brew cleanup, brew update, brew upgrade to update. There is no any error. Once use brew install openexr to install, error show up:

  target with the same name already exists.

Solve this problem by checkout previous commit of Homebrew.
