warning: cannot find clang intrinsic headers; please report this issue to the OSXCross project

[efa]

Sorry, I posted before in a closed Issue.

osxcross worked perfectly in the past with Debian 10, it is installed in /opt/osxcross Now I upgraded to Debian 11, I do not know if was the upgrade that broke the /opt installation, the file are there 3.5 GB not touched. See the error below:

I have no link in /usr, I do not know where (and what) are the clang intrinsics, but should be in osxcross directory Please suggest a work around. I had to reinstall osxcross?

maybe those one:

Can be related to the fact I previously used: SDK_VERSION=10.12 OSXCROSS_TARGET=darwin16 to cross-compile GTK for Quarz backend, then switched to 10.14/darwin18 and for some reasons there are no *intrin.h in the path: /opt/osxcross/target/SDK/MacOSX10.14.sdk/System/Library/Frameworks/OpenCL.framework/Versions/A/lib/clang/3.2/include and neither in: /opt/osxcross/target/SDK/MacOSX10.14.sdk/ at all?

But I'm sure I had successfully crosscompiled a QT app after the switch to 10.14: https://www.alus.it/AirspaceConverter/download.php?lang=en https://github.com/alus-it/AirspaceConverter https://www.alus.it/AirspaceConverter/ and also this one: https://github.com/efa/Wilderland

solved. I had to reinstall those packages: $ sudo apt install clang-11 libclang-common-11-dev libobjc-10-dev libobjc4 libomp-11-dev libomp5-11
