include/cxx contains NuttX's mini C++ ABI shims and must only be added to the include path when CONFIG_LIBMINIABI is selected. tools/Config.mk was adding it unconditionally for every non-LIBCXX/non-UCLIBCXX build, and the platform.cmake files for arm, arm64, risc-v, x86_64 and tricore were adding it inside the CONFIG_LIBCXXTOOLCHAIN block. With an unpatched downloaded ARM GNU Toolchain, <cstdlib> uses newlib's stdlib.h, defining div_t as an anonymous struct. A later inclusion of NuttX's stdlib.h via <cstdio>->stdio.h->kmalloc.h then redefines div_t with struct tag div_s, causing a conflicting declaration error. Guard the div_t/ldiv_t/lldiv_t definitions in stdlib.h with redefinitions when a toolchain stdlib.h was already processed. Also fix lldiv_s members typed as long instead of long long.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
