Hello, I'm looking for some help with a build error I'm encountering. I did the following steps to use Nuttx with my Spresense board:
sudo apt install bison flex gettext texinfo libncurses5-dev libncursesw5-dev gperf automake libtool pkg-config build-essential gperf genromfs libgmp-dev libmpc-dev libmpfr-dev libisl-dev binutils-dev libelf-dev libexpat-dev gcc-multilib g++-multilib picocom u-boot-tools util-linux kconfig-frontends sudo apt install gcc-arm-none-eabi binutils-arm-none-eabi <pre>mkdir nuttx cd nuttx git clone https://github.com/apache/incubator-nuttx.git nuttx git clone https://github.com/apache/incubator-nuttx-apps apps cd nuttx ./tools/configure.sh -l spresense:nsh make -j And I get the following error: Create version.h LN: platform/board to /home/SONY/s1000325098/repos/NuttxWorkshop/apps/platform/dummy Register: sh Register: nsh CXX: libcxxmini/libxx_delete.cxx arm-none-eabi-g++: error: unrecognized command line option '-std=gnu++20'; did you mean '-std=gnu++2a'?
