    Hi,

    Which version of Qt are you using ?
    Did you completely nuke the build folder after the Xcode update ?

      Also, do you get the same errors if you upgrade your Xcode to 16.0?

        @SGaist Thanks for reply. I got Qt 6.5.0. And I didn’t remove build folder after Xcode update.

                  Do you have the same issue if you create a new project ?

                      I just checked on my Mac running Xcode 16.0 (Sonoma 14.6.1) the definition for uint8_t comes from this file:
                      /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/_types/_uint8_t.h

                      The file contains a single typedef:
                      typedef unsigned char uint8_t;

                        EDIT:
                        Errors are gone after two steps:

                        1. Added set(CMAKE_OSX_SYSROOT "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.sdk") to top-level CMakeLists.txt;
                        2. In build configuration (Project options) changed value of WrapOpenGL_AGL to point to the right SDK (15 instead of 14.5).

                        I presume those would not be necessary once the proper update to Qt comes in, with support for the new SDK?

                        EDIT ENDS.

                        Weird errors after the update:

                                      At this point, you should try to build a dummy basic hello world using uint8_t without anything Qt in it to ensure that your setup is working.
