aviralgarg05 commented on PR #18374:
URL: https://github.com/apache/nuttx/pull/18374#issuecomment-3957382647
- The originally reported failure (`std::abs/std::acos/...` not declared
from `<math.h>`) is no longer present after this patch.
- The build still stops later in my local macOS simulator-host setup due to
a different, unrelated header/type conflict (`div_t`, `ldiv_t`, `putenv`,
`dev_t`, `mode_t`) between Darwin and NuttX libc declarations.
