CyanogenMod × × and compilation and simple modification

The editor compiles the version of gingerbread, that is, android 2.3.7, into a package of rom that can be used by nexus S crespo phones.
However, the official website under CyanogenMod is actually used at present.
Repo init-u git://github.com/CyanogenMod/android.git-b cm-10.2
This version is compiled and explained, and
The cm versions supported by the phone are as follows
CM Support: 7, 9, 10, 10.1, 10.2, 11
Here we compile the new version again, and through this operation, we can complete the effect of burning a phone into different android versions of the rom package.
A prerequisite:
1 configure the compilation environment of android
For details of the configuration method, please see the http://source.android.com/source/initializing.html web page.
2 download the source code
Curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~ / bin/repo
Need to use the repo tool provided by CyanogenMod
Repo init-u git://github.com/CyanogenMod/android.git-b cm-10.2
Download the appropriate branch
Repo sync
download
As before, if you have already downloaded the cm-10.2 version, you don't need to download it anymore, which can save a lot of time.
3 Samsung Google Google Nexus S ("crespo") mobile phone
In my cell phone.
About cell phones.
Model No.: Nexus S
Baseband version: I9020XXKl1
4 brushing machine tools, such as perfect brushing machine
Two important web pages
1 http://wiki.cyanogenmod.org/w/Devices#vendor=;
This page contains all the models supported by cm and the corresponding drivers
2 http://wiki.cyanogenmod.org/w/Crespo_Info
This page contains all kinds of information that crespo needs before compilation.
The most important of these is
Device https://github.com/cyanogenmod/android_device_samsung_crespo
Kernel https://github.com/cyanogenmod/android_kernel_samsung_crespo
Both packages need to be downloaded.
Where the driver package:
After downloading and decompressing, put it in cm-10/device/samsung/crespo and crespo this folder if you don't want to create a new one.
Kernel package
After downloading and decompressing, put it in cm-10/kernel/samsung/crespo and crespo this folder if you don't want to create a new one.
Also note that there is also a hardware package
Https://github.com/CyanogenMod/android_hardware_samsung
After downloading and decompressing, put it in cm-10/hardware/samsung and samsung this folder if you don't want to create a new one.
3 http://wiki.cyanogenmod.org/w/Build_for_crespo
This page tells you how to compile this version of crespo cm-10.2 code
Three compiled source code
1 preparation before compilation
Cd ~ / android/system/vendor/cm
. / get-prebuilts
2. / extract-files.sh
First connect the samsung nexus S phone, then go to the cm-10/device/samsung/crepso directory and execute the above instructions.
The main function of this script is to pull the driver so library in the phone, then create a new cm-10/vendor/samsung/crespo directory, and then put the corresponding library files in it.
My phone did not report a single error when executing this command. If any files are missing, please see the previous article and fill in the so library.
3 really start compiling
In the past, there was no need for lunch commands to choose which version to compile. CyanogenMod has encapsulated these into simpler commands.
After returning to the root directory
Export USE_CCACHE=1
It is said that this will speed up the compilation
. Build/envsetup.sh
Only after the successful execution of this important can the later commands continue to be executed.
Croot
Brunch crespo
Ok starts compiling.
Fourth, use the brushing tool to brush the rom package to the mobile phone.
This is how CyanogenMod compiles Google Nexus S "crespo"). The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
