It seems that there is no stdbool.h in your cross compile environment.
It works well with the following steps, you can try it.
wget https://github.com/loongson/build-tools/releases/download/2023.08.08/x86_64-cross-tools-loongarch64-gcc-libc.tar.xz tar xf x86_64-cross-tools-loongarch64-gcc-libc.tar.xz -C /opt export PATH=/opt/cross-tools/bin/:$PATH export LD_LIBRARY_PATH=/opt/cross-tools/loongarch64-unknown-linux-gnu/lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=/opt/cross-tools/lib:$LD_LIBRARY_PATH export CROSS_COMPILE=loongarch64-unknown-linux-gnu- export ARCH=loongarch
find /opt -name stdbool.h /opt/cross-tools/lib/gcc/loongarch64-unknown-linux-gnu/14.0.0/include/stdbool.h /opt/cross-tools/loongarch64-unknown-linux-gnu/include/c++/14.0.0/tr1/stdbool.h
cd linux.git make loongson3_defconfig make menuconfig # select CONFIG_UNWINDER_ORC make -j4
Thanks, Tiezhu
