hey @xiaoxiang781216 ok so we have 2 problems.
First problem is the following:
```
Error:
/github/workspace/sources/nuttx/include/libcxx/__iterator/segmented_iterator.h:72:46:
error: template argument '(sizeof (_Tp) * 0)' involves template parameter(s)
```
This i figured out why. Basically i pulled the docker image and found the
the gcc version 11 and for newer llvm versions require gcc version >= 12. I
updated the gcc version in my local container to test and it resolved this
specific issue.
The second problem that you mention i am not sure how to solve it yet :') .
