Hi I follow your posts regularly. I am interested in converting some of my gcc projects to clang. This article is a great starting point. However, I am stuck early on in the scan-build step. I am getting the following errors:
~/.../example/freertos-example-llvm >>> scan-build make
scan-build: Using '/usr/bin/clang-10' for static analysis
/usr/bin/../lib/clang/ccc-analyzer
===GCC Compiler Detected===

I have installed clang 10 on arch and I also have arm-none-eabi-gcc installed. What am I missing? Thanks in advance for any pointers.
