记录一下Ubuntu22下编译的坑点

[Nagico]

依赖安装

编译过程中提示缺少文件 error while loading shared libraries: libdebuginfod.so.1: cannot open shared object file: No such file or directory，应该不太影响编译，但还是多安装了些包

sudo apt install -y zip bison build-essential cmake flex git libedit-dev libllvm14 llvm-14-dev libclang-14-dev python3 zlib1g-dev libelf-dev libfl-dev python3-setuptools liblzma-dev libdebuginfod-dev arping netperf iperf

Openssl兼容

编译需要1.1版本的openssl，系统默认3.0，会出现 -Wdeprecated-declarations

打开网站 (http://security.ubuntu.com/ubuntu/pool/main/o/openssl/) 依次下载以下包并安装

• libssl1.1_1.1.1f-1ubuntu2.x_amd64.deb
• libssl-dev_1.1.1f-1ubuntu2.x_amd64.deb
• openssl_1.1.1f-1ubuntu2.x_amd64.deb

自己搜一下到底是ubuntu2.多少，目前是2.19

# download binary openssl packages from Impish builds
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/openssl_1.1.1f-1ubuntu2.19_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl-dev_1.1.1f-1ubuntu2.19_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.19_amd64.deb

# install downloaded binary packages
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.19_amd64.deb
sudo dpkg -i libssl-dev_1.1.1f-1ubuntu2.19_amd64.deb
sudo dpkg -i openssl_1.1.1f-1ubuntu2.19_amd64.deb

编译参数

注意下路径就行了

cd kernel

export ARCH=arm64
export CROSS_COMPILE=../gcc/gcc-arm64-gcc-master/bin/aarch64-elf-
export CROSS_COMPILE_ARM32=../gcc/gcc-arm-gcc-master/bin/arm-eabi-

make cas_defconfig

make -j

scripts/Makefile.dtbo 文件缺失

copy 这个就行了 (https://github.com/XayahSuSuSu/android_kernel_xiaomi_cas/blob/arrow-13.0/scripts/Makefile.dtbo)
