JUCE 7 causing "Undefined symbols for architecture x86_64"

[jdh9862]

I recently updated to JUCE 7, and began getting this error when I try to build with CLion using CMake

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_MTLTextureDescriptor", referenced from:
      objc-class-ref in libBasic.a(include_juce_gui_basics.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

From a little digging, I think something is up with how FRUT is generating the CMake file. I am still able to build/run my code with Xcode using Projucer.

@jdh9862 thanks for using FRUT!

Basic support for JUCE 7 was added in #724, which was merged 19 days ago. Which commit of FRUT are you using?

[jdh9862]

I am at the head of main. I see the commit you are referring to, but I am still experiencing this issue. I have tried deleting CMakeLists.txt and cmake-build-debug to try to get a clean build, but the error is persisting.

@jdh9862 Could you please add these two lines to your CMakeLists.txt file (after the line that contains include(Reprojucer)):

file(SHA1 "${Reprojucer.cmake_DIR}/Reprojucer.cmake" reprojucer_hash)
message(STATUS "${reprojucer_hash}  ${Reprojucer.cmake_DIR}/Reprojucer.cmake")

and tell me what gets printed when you configure your project?
Thanks!

-- Reprojucer.cmake's hash is: 5ac16e71c903c33f9331c81d8910728d7112d0d0

@jdh9862 I'm sorry, I edited my previous comment and changed the second line to add. Could you please edit your CMakeLists.txt to match and give me the output?

@jdh9862 FRUT/prefix/FRUT/cmake/Reprojucer.cmake was copied from FRUT/cmake/Reprojucer.cmake when you ran cmake --build . --target install inside of FRUT/build. The files under FRUT/prefix don't get updated by checking out a different commit.

You either need to:

• update all the files that are located under FRUT/prefix by running:

  cd FRUT/build
  cmake --build . --target install
  

• use FRUT/cmake/Reprojucer.cmake in your CMakeLists.txt by changing the line that appends to CMAKE_MODULE_PATH:

  -list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/../FRUT/prefix/FRUT/cmake")
  +list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/../FRUT/cmake")
   include(Reprojucer)

That fixed everything, thank you :)
