Orange PI 4B no screen and clang++ not working correctly

[FredrikA]

My Orange Pi 4B has gone to community support.
After an overheat with a compilation, the ssd dies, and I reflashed to the new community version

Armbian_community_24.8.0-trunk.399_Orangepi4_noble_current_6.6.40_gnome-oibaf_desktop
Anyway I got no HDMI output so I left it running, and suddenly I got a new device on the network.
Since I am going to use it headless it works well for me.

Bug 1
No HDMI

Expected HDMI output works

Actual Result No HDMI output.
 

Bug 2

The second was when I downloaded llvm compiler
normal output from clang compiler:

(took the whole day yesterday to compile from source without overheating)

clang++ -v
clang version 19.0.0git (https://github.com/llvm/llvm-project.git 4c73b1a986bb4f3af6c5d5e9e705934dbcc36262)
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/local/bin
Found candidate GCC installation: /usr/lib/gcc/aarch64-linux-gnu/13
Selected GCC installation: /usr/lib/gcc/aarch64-linux-gnu/13
Candidate multilib: .;@m64
Selected multilib: .;@m64

but what i got from the clang++ compiler downloaded with apt-get
/usr/bin/clang++ -v
Ubuntu clang version 18.1.3 (1ubuntu1)
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

So some file helping clang finding header files from gcc (the last part "found candidate .... selected multillib") is missing

Expected result clang++ finds g++ header files

Actual result clang++ don't find g++ header files

Please note that after compiling installing clang++ from git, the installed clang++ start to work as expected.

Thanks for the feedback.
Everything else is not an Armbian problem.
LLVM is not used when building Armbian images.

Also with updated kernel /boot/vmlinuz-6.6.41-current-rockchip64 there is no HDMI
