No rule to make target '/bin/mkdisp' crosscompile using sleef/toolchains/aarch64-gcc.cmake

[BellaWangY]

I use this cmake cmd for configuration for arm arch64 for crossing compile and my desktop is ubuntu system. I runinto some errors please see the logs. how to solve it? Step1, cmake -DCMAKE_TOOLCHAIN_FILE=./toolchains/aarch64-gcc.cmake -D DBUILD_SHARED_LIBS=OFF -S . -B build

Hey, just letting you know I am looking into this now. First thoughts that come into my mind is why you're not passing a native build? I think that might solve your issues. Something like:

cmake -S . -B build-native
cmake --build build-native -j --clean-first

cmake -DCMAKE_TOOLCHAIN_FILE=./toolchains/aarch64-gcc.cmake \
      -DNATIVE_BUILD_DIR="$(pwd)/build-native" \
      -DBUILD_SHARED_LIBS=OFF \
      -S . -B build_557

cmake --build build_557 -j --clean-first

Also make sure you have gcc cross compiler installed:

sudo apt-get install gcc-aarch64-linux-gnu

If you want to fix with gcc-9 then: sudo apt-get install gcc-9-aarch64-linux-gnu
