Error compiling TKService with Coca on Apple with GCC

Hi,

There is a compilation error related to the Cocoa API when compiling TKService with GCC. In particular, when compiling the file Cocoa/Cocoa_LocalPool.mm. The build instruction is

cd /PATH_TO_OCCT/out/build/src/TKService && /opt/homebrew/bin/aarch64-apple-darwin23-g++-14 -DHAVE_FREETYPE -DHAVE_OPENGL_EXT -DOCC_CONVERT_SIGNALS -I/opt/homebrew/include/freetype2 -I/PATH_TO_OCCT/out/build/include/opencascade -fexceptions -fPIC -Wall -Wextra -O3 -DNDEBUG -s -std=gnu++11 -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.5.sdk -DOCCT_NO_PLUGINS -MD -MT src/TKService/CMakeFiles/TKService.dir/__/Cocoa/Cocoa_LocalPool.mm.o -MF CMakeFiles/TKService.dir/__/Cocoa/Cocoa_LocalPool.mm.o.d -o CMakeFiles/TKService.dir/__/Cocoa/Cocoa_LocalPool.mm.o -c /PATH_TO_OCCT/src/Cocoa/Cocoa_LocalPool.mm

and the error

Can someone help me? I am running on macOS Sonoma 14.5, using GCC 14.1.0 installed through Homebrew.

Everything works smoothly when using Clang or Apple clang.

Thanks!
