编译kernel问题

ranfish

ubuntu18.04编译环境按wiki配置好

sdk无修改，下载后解压、git reset --hard均正常

按wiki编译，整体编译和分步编译，编译到kernel部分时均出现以下错误
（网上有说liblz4-tool没安装，实际上已经安装）

请问是什么问题？

附wiki编译方法
Core-3588J 产品编译方法整体编译

• HDMI 固件编译

  
  

./FFTools/make.sh -d rk3588-firefly-itx-3588j -j8 -l rk3588_firefly_itx_3588j-userdebug./FFTools/mkupdate/mkupdate.sh -l rk3588_firefly_itx_3588j-userdebug

• 10.1 寸 MIPI DSI0 固件编译：

  
  

./FFTools/make.sh -d rk3588-firefly-itx-3588j-mipi101-M101014-BE45-A1 -j8 -l rk3588_firefly_itx_3588j-userdebug./FFTools/mkupdate/mkupdate.sh -l rk3588_firefly_itx_3588j-userdebug


分步编译

编译前执行如下命令配置环境变量：

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64export PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

• 编译 kernel：

  
  

cd ~/path/to/sdk/kernel-5.10export PATH=../prebuilts/clang/host/linux-x86/clang-r416183b/bin:$PATHalias msk='make CROSS_COMPILE=aarch64-linux-gnu- LLVM=1 LLVM_IAS=1'msk ARCH=arm64  firefly_defconfig android-11.config pcie_wifi.configmsk ARCH=arm64   BOOT_IMG=../rockdev/Image-rk3588_firefly_itx_3588j/boot.img rk3588-firefly-itx-3588j.img -j8

ranfish

谢谢，已经解决

PS:
. build/envsetup.sh
mmm external/lz4/
还是会报错，懒得去解决

按这个思路，我是直接

git clone https://github.com/lz4/lz4.git
make
sudo make install
