1 P6: Trial Build of a ROM Nikhil George 1. Introduction. Overview of the build task. Cite the build/ wiki articles you read. Installation of required packages sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-\ dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386\ libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-\ dev:i386 openjdk-7-jdk Update the default java version to openjdk sudo update-alternatives --config java sudo update-alternatives --config javac Initialize the Build Environment Initialize the environment it is equivalent to xconfig or menuconfig in case of Linux kernel build but unlike Linux, AOSP uses a set of variables for indicating kernel configuration. These variables are set as environment variables to the current shell via envsetup.sh command. build/envsetup.sh Choose a build target command choose which target to build. The exact configuration can be passed as an argument lunch aosp_arm-eng Build the Code make build everything. GNU make can handle parallel tasks with a-jn argument. N is denoted the number of parallel tasks. make -j 10 Reference Links:

2 2. Identification of the Sources. AOSP? CyanogenMod? Version numbers. Identification of the tools used; i.e., version numbers of gcc, make, repo,... gcc version GNU Make version: 3.81 AOSP version: Identification of the Build Platform. Details of your PC/laptop. Desktop:- Dell Optiplex 390 Memory:-7.7 GiB Processor:-Intel Core i GHz 4 Graphics:-Intel Sandybridge Desktop OS-Type:-64-bit OS:- Ubuntu LTS Kernel version:-linux rc1-x86_64-with-ubuntu trusty Disk: GB 4. Statistics. How long did it take to build? The output of ps aux and free at selected points in time. Sizes of the directory before and after the build. AOSP Size before Build:26 GB Size after Build: 50 GB Build Start: 12:36:22 IST 2014 Build Finish: 14:53:01 IST 2014 Total Time =2 Hr 23 Mins

Appendix: Fairly long. Complete capture of stdout and stderr of all the build steps. Use subsections. Precede the captured with a bit of explanation. envsetup.sh Initialize the environment it is equivalent to xconfig or menuconfig in case of Linux kernel build but unlike Linux, AOSP uses a set of variables for indicating kernel configuration.
