记录一下Build CyanogenMod ROM 时修改过的地方

发表于   |   分类于

用CyanogenMod成功build出I9000（galaxysmtd）的ROM，记录一下build过程中所修改的文件，以便参考。

1.build/core/main.mk

ADDITIONAL_DEFAULT_PROPERTIES += ro.secure=0

改为0之后，以后adb shell 自动进入到root

 

2.build/tools/releasetools/common.py

cmd = [“java”, “-Xmx2048m”, “-jar”, os.path.join(OPTIONS.search_path, “framework”, “signapk.jar”)]

在虚拟机中build，2G内存实在没有，改小成650m了，build时间长点没关系，慢慢等

 

3.build/envsetup.sh

function mka() 中的下面一行最终被调用进行make，

schedtool -B -n 1 -e ionice -n 1 make -j$(cat /proc/cpuinfo | grep “^processor” | wc -l) “$@” showcommands

如果想在build过程显示详细的命令执行信息，可以加上showcommands

 

4.build/tools/releasetools/ota_from_target_files

updating_recovery = (source_recovery.data != target_recovery.data)

改为 updating_recovery = False，这样不用update recovery

 

5.build/tools/roomservice.py

os.system(‘repo sync %s’ % repo_path) 会调用repo sync

fetch_dependencies(repo_path, fallback_branch) 会repo sync依赖的project

如果fetch失败，可以将前面一行注释掉，下次build时跳过repo sync，速度快点

 

6.生成ota update.zip

./build/tools/releasetools/ota_from_target_files -v -i mnt/build/ota/cm_galaxysmtd-target_files-eng.jfo.20130125.zip mnt/build/ota/cm_galaxysmtd-target_files-eng.jfo.20130214.zip update-20130125_20130214.zip

 

7.其他编译选项

export OUT_DIR_COMMON_BASE=<path-to-your-out-directory>
make -j4 CYANOGEN_WITH_GOOGLE=true otapackage

 

8.产生ota package以及签名，参考日志otapkg_cmd

./build/tools/releasetools/ota_from_target_files -v \
       -p /home/jfo/android/system/mnt/build/out/system/host/linux-x86 \
       -k build/target/product/security/testkey \
       –backup=true \
       –override_device=galaxys,galaxysmtd,GT-I9000,GT-I9000M,GT-I9000T \
       /home/jfo/android/system/mnt/build/out/system/target/product/galaxysmtd/obj/PACKAGING/target_files_intermediates/cm_galaxysmtd-target_files-eng.jfo.zip /home/jfo/android/system/mnt/build/out/system/target/product/galaxysmtd/cm_galaxysmtd-ota-eng.jfo.zip

java -Xmx650m -jar /home/jfo/android/system/mnt/build/out/system/host/linux-x86/framework/signapk.jar -w build/target/product/security/testkey.x509.pem build/target/product/security/testkey.pk8 /tmp/tmpi1Xn7t /home/jfo/android/system/mnt/build/out/system/target/product/galaxysmtd/cm_galaxysmtd-ota-eng.jfo.zip
