I.MX6q環境中下載和編譯android8.0源碼------不再更新8.0

１／去飛思卡爾官網下載相關資料，如下鏈接：

https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-software-and-development-tool:IMX-SW

需下載　imx-o8.0.0_1.0.0_ga.tar.gz　文件，鏈接如下：　（註冊下載）

https://www.nxp.com/webapp/sps/download/preDownload.jsp

２／配置環境

（android官方Ubuntu 14.04環境下所需）

sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip

（飛思卡爾所需軟件包）

sudo apt-get install uuid uuid-dev
sudo apt-get install zliblg-dev liblz-dev
sudo apt-get install liblzo2-2 liblzo2-dev
sudo apt-get install lzop
sudo apt-get install git-core curl
sudo apt-get install u-boot-tools
sudo apt-get install mtd-utils
sudo apt-get install android-tools-fsutils
sudo apt-get install openjdk-8-jdk
sudo apt-get install device-tree-compiler
sudo apt-get install gdisk

３／配置git

git config--global user.name“first last”

git config--global user.email“[email protected]”

４／接下解壓　imx-o8.0.0_1.0.0_ga.tar.gz　文件到根目錄（可以複製到）

tar xzvf mx-o8.0.0_1.0.0_ga.tar.gz

５／下載源碼

mkdir ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=${PATH}:~/bin
source ~/imx-o8.0.0_1.0.0_ga/imx_android_setup.sh

默認情況下，imx_android_setup.sh腳本將創建源代碼構建環境
在文件夾~/android_build中

漫長等待之後。。。。下載成功，如下顯示

Android source is ready for the build

 如果出現 error: Exited sync due to gc errors 的原因，除非的你的ubuntu版本真的很老，可以google解決之外。解決不了的情況下，重裝系統是首要選擇。我的是18.04，我由於上次下載的android8.1官方版的沒有刪除乾淨導致，浪費了太長時間在查找問題上，重裝系統之後一步到位。

關於編譯如下，

source build/envsetup.sh

lunch sabresd_6dq-userdebug

make 2>&1 | tee build-log.txt

編譯過程中出現

 build stopped: subcommand failed.問題

執行

export LC_ALL=C

然後重複上述編譯過程。

 

 

。。。。。。。。。。。。。。。。。經過領導安排，由於種種原因，最終還是選擇了4.4.2版本（驅動之類的已經完善，更穩定，更適配目前的硬件），所以之後不再涉及高版本的源碼相關知識，或許，當硬件大升級之後，會做高版本的處理再來研究吧，後續博客會更新我的4.4.2 開發遇到得問題和困難以及如何解決問題的
