Android快速编译

Posted 2021-07-17 四季帆

1. 获取编译所用的命令和配置

source build/envsetup.sh
lunch xx 
make showcommands bootimage >build.log      //通过参数showcommands 将编译的命令显示出来

2. 制作编译脚本

touch buld_kernel.sh               //创建脚本
复制第三步编译的build.log中 bin/bash -c 开始的每一段到buld_kernel.sh里
在脚本之前加上 source 和 lunch 就可以了
chmod +x buld_kernel.sh       //增加可执行全限
./build_kernel.sh             //运行编译脚本，以后每次编译使用这个脚本就可以了

3. 高通平台sdm450例子，下面是制作的脚本

source build/envsetup.sh
lunch 19
     
/bin/bash -c "(if [ ! -z \\"hq_sdm450_defconfig\\" ]; then            rm -f ../../out/target/product/hq_sdm450/obj/kernel/msm-4.9/.config;            make -j2 -C kernel/msm-4.9 O=../../out/target/product/hq_sdm450/obj/kernel/msm-4.9 DTC_EXT=dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- hq_sdm450_defconfig;             make -j2 -C kernel/msm-4.9 O=../../out/target/product/hq_sdm450/obj/kernel/msm-4.9 DTC_EXT=dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- headers_install;         if [ -d \\"out/target/product/hq_sdm450/obj/kernel/msm-4.9/usr/include/bringup_headers\\" ]; then                 cp -Rf  out/target/product/hq_sdm450/obj/kernel/msm-4.9/usr/include/bringup_headers/* out/target/product/hq_sdm450/obj/kernel/msm-4.9/usr/include/ ;            fi ;            fi ) && (if [ \\"hq_sdm450_defconfig\\" != \\"hq_sdm450_defconfig\\" ]; then            echo \\"Used a different defconfig for header generation\\";          rm -f ../../out/target/product/hq_sdm450/obj/kernel/msm-4.9/.config;            make -j2 -C kernel/msm-4.9 O=../../out/target/product/hq_sdm450/obj/kernel/msm-4.9 DTC_EXT=dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- hq_sdm450_defconfig; fi ) && (if [ ! -z \\"\\" ]; then             echo \\"Overriding kernel config with ''\\";          echo  >> out/target/product/hq_sdm450/obj/kernel/msm-4.9/.config;           make -j2 -C kernel/msm-4.9 O=../../out/target/product/hq_sdm450/obj/kernel/msm-4.9 DTC_EXT=dtc CONFIG_BUILD_ARM64_DT_OVERLAY=y ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- oldconfig; fi )"
