##How To Build
Although this device is not officially supported, the build-steps are not that different between devices. Most of the information on this "How to build" page also apply to this device: http://wiki.lineageos.org/w/Build_for_t0lte
Requirements:
- At least 8GB RAM (build will stop without a warning with 6GB)
- 65GB (sources and build results) + 35GB (CCACHE)
Perform the following steps from the above "How to build":
-
Install the SDK
-
Install the Build Packages
-
Create the directories
$ mkdir -p ~/bin $ mkdir -p ~/android/system
Note: you can replace the build root "
/android/system" with any directory you like. Let's assume it is "/android/system" in the following steps. -
Install the repo command
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo $ chmod a+x ~/bin/repo
-
Put the ~/bin directory in your path of execution
-
Initialize the LineageOS source repository
$ cd ~/android/system/ $ repo init -u https://github.com/LineageOS/android.git -b cm-13.0
-
Download the source code
$ repo sync
-
Patch sources
8.1. Clone the local manifests with the following commands:
$ cd ~/android/system/ $ git clone https://github.com/cm-3470/android_.repo_local_manifests -b cm-13.0 .repo/local_manifests
However if you already obtained local manifests from a different device, just copy at least the following files into .repo/local_manifests :
- https://github.com/cm-3470/android_.repo_local_manifests/blob/cm-13.0/degaslte.xml
- https://github.com/cm-3470/android_.repo_local_manifests/blob/cm-13.0/common.xml
8.2. Fetch device specific repos by synching all repos
$ repo sync
8.3. Apply device specific patches (also repeat this step whenever the patches in the directory "patch" are modified):
$ cd device/samsung/smdk3470-common/patch $ ./apply.sh
-
Prepare the device-specific code
This step is device specific and hence different from the "How to build".
$ source build/envsetup.sh $ lunch lineage_degaslte-userdebug
These commands only have a temporary effect, you will have to perform these commands again, when you use a new terminal window.
-
Turn on caching to speed up build
Only if you want to rebuilt LineageOS multiple times you also should enable CCACHE
-
Start the build
$ croot $ mka bacon
###Build-results:
The build-process takes a lot of time - the initial build can take about 10h. If CCACHE is enabled, the next builds only take 3-4 hours. Note that especially the linking process (ld) needs a huge amount of memory. The building process stops without a warning if only 6GB are present. In this case you can try to build with only one process (mka bacon -j1).
When the build-process finished the following files will be available:
LineageOS image: out/target/product/degaslte/cm-13.0-<date>-UNOFFICIAL-<device>.zip
recovery: out/target/product/degaslte/recovery.img
###Rebuild:
If you want to rebuild the ROM, perform the following steps:
$ repo sync
$ mka clean
$ mka bacon
"repo sync" might fail due to local source code modifications. In this case temporarily revert the changes and reapply them after the update:
$ repo sync (-> fails due to local modifications, failing subprojects are listed in log-output)
For each failing subproject, revert the changes (e.g. with git reset --hard ...)
$ croot
$ repo sync
Now reapply the patches (see section about device/samsung/smdk3470-common/patch/apply.sh)
