@xuxin930 @xiaoxiang781216 any idea why the CI reported this issue many times:

Check failure on line 51 in include/nuttx/wdog.h GitHub Actions / macOS (macos)

missing binary operator before token "("

@acassis @xiaoxiang781216 The problem is here https://github.com/apache/nuttx/actions/runs/8479414330/job/23233475816?pr=12022#step:7:1313 Configuring... make: *** [olddefconfig] Error 1 Enabling CONFIG_ARM_TOOLCHAIN_GNU_EABI make: *** [olddefconfig] Error 1

I think clearing the cache solves the problem https://github.com/apache/nuttx/actions/caches

@acassis @simbit18 It seems that similar situations have happened before refer to: https://github.com/apache/nuttx/pull/10543

@xuxin930 exactly !!! cache must be cleared manually.

I tried this and it works, the artifact runs on CanMV230 device as well:

Only one minor issue met during CMake configuration process:

$ rm -rf * && cmake ~/Projects/Nuttx/nuttx -DBOARD_CONFIG=canmv230/pnsh -G Ninja

@xuxin930,

Here I tried this again with GCC toolchain v10.2 got via apt install gcc-riscv64-unknown-elf on Ubuntu.

It seems that we can avoid the above cmake config time warning by dropping the CMAKE_C_FLAGS from the libgcc checking command in line 755.

[xiaoxiang781216]

@xuxin930 should we rebase the code
