I'm in the process of upgrading the system, maybe I've not installed something, but everything is in the process of `emerge -avtqbUDuke @world` (notice -e aka --emptytree)
it seems to be continuation of bug https://bugs.gentoo.org/678080 and https://bugs.gentoo.org/678098

Please, notice that I'm using a default profile with GCC compiler, not clang.
After manually adding -L/usr/lib/llvm/19/lib64 to COMMON_FLAGS and LDFLAGS via an env file, it gives a lot of `undefined reference ...` and the symbols it looking for in /usr can be found only in /usr/lib/llvm/19/lib64/libclang.so.19.0.0git3ae67557 or any libclang.so for any llvm version from 15 to 19. I've checked that via `rg -al clang_getArgType`
Oh, maybe I got it: ``` Checking for libclang... LLVM/Clang version >= 3.9.0 required, version provided: 19.0.0git3ae67557. no ... WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation. Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation. On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution. On macOS, you can use Homebrew's llvm package. On Windows, you must set LLVM_INSTALL_DIR to the installation path. ``` So, it have found libclang but refused to use it?
Ok, my PATH was next: ``` /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib/llvm/19/bin:/usr/lib/llvm/18/bin:/usr/lib/llvm/17/bin:/usr/lib/llvm/16/bin:/usr/lib/llvm/15/bin:/opt/android-sdk-update-manager/tools:/opt/android-sdk-update-manager/platform-tools:/etc/eselect/wine/bin:/opt/cuda/bin:/opt/cuda/libnvvp ``` I removed /usr/lib/llvm/19/bin so that llvm-config --version in the terminal now show 18.1.3 . And still it somehow finds libclang with version 19.0.0git3ae67557
I've solved it via 1. Removing path from PATH with llvm-config with version 19.0.0git3ae67557 2. Setting LLVM_INSTALL_DIR=/usr/lib/llvm/18/ Diagnosis: qmake cannot understand that version 19.0.0git3ae67557 a. is a version b. cannot check that it newer than 3.9.0
