[Honor 5X Questions & Answers] yuweng:
Since many have pm & ask me how to build ROMs for kiwi & i have to repeat myself every time, as might as well once & for all, i post the info here... :cool:

Before you can build any other custom ROMs, you'll have to learn to build cm-13.0 referring to this Official Guide then you can move on to other ROMs, Thanks to crpalmer & BadDaemon... :good:

If you're a first time ROM Cooker then i strongly recommends BBQLinux bcos you don't have to setup the build environment, everything is already built-in, my guide here, Thanks to my Master Shifu codeworkx... :good:

There are only two types of Android sources, AOSP & CAF, all custom ROMs will use either one of them including cm... :cool: You'll only need two folders AOSP & CAF, syncing all custom ROMs to these same folder will cut the syncing time more than half ! AOSP manifest will have this line while CAF manifest will have this so sync it to the correct folder.

In actual fact, it doesn't really matter, both sources have different file names & you can actually sync it to the same folder but its best practice to have two separate folders for two separate sources.

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="CyanogenMod/android_device_huawei_kiwi" path="device/huawei/kiwi" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_external_sony_boringssl-compat" path="external/sony/boringssl-compat" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_external_stlport" path="external/stlport" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_kernel_huawei_kiwi" path="kernel/huawei/kiwi" remote="github" revision="cm-13.0" />
<project name="TheMuppets/proprietary_vendor_huawei" path="vendor/huawei" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_device_qcom_common" path="device/qcom/common" remote="github" revision="cm-13.0" />
</manifest>

kiwi.xml

To sync the sources, Eg. cm-13.0

mkdir -p ~/AOSP/.repo/local_manifests
repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0
Copy [COLOR="Blue"]kiwi.xml[/COLOR] to ~/AOSP/.repo/local_manifests
repo sync -fc[COLOR="blue"]j64[/COLOR] --force-sync [COLOR="blue"]<= Depending on your ISP, this will use parallel threads & cut the downloading time by half. If error then lower it[/COLOR]

To build AOSP based custom ROMs, this Eg. cm-13.0, open a Terminal, copy the below & paste to it

cd ~/AOSP
prebuilts/misc/linux-x86/ccache/ccache -M 50G
export USE_CCACHE=1
export LC_ALL=C
source build/envsetup.sh
brunch kiwi 2>&1 | tee ~/AOSP/[COLOR="blue"]compile.log[/COLOR]

If there is any build error then refer to the compile.log & start goggling for the fix !

For any other custom ROMs, refer to the guide at their manifest, Eg. below Krexus-CAF

mkdir -p ~/CAF/.repo/local_manifests
Copy [COLOR="blue"]kiwi.xml[/COLOR] to ~/CAF/.repo/local_manifests [COLOR="Blue"]<= Remove qcom/common as Krexus-CAF already [URL="https://github.com/krexus-caf/manifest/blob/caf/default.xml#L101"]have it[/URL][/COLOR]
cd ~/CAF
repo init -u [url]https://github.com/krexus-caf/manifest.git[/url] -b caf
repo sync -fcj68 --force-sync --no-clone-bundle --no-tags

To build it, you can also create a script as below, name it krexus then simply sh krexus will start the build... :cool:

cd ~/CAF
prebuilts/misc/linux-x86/ccache/ccache -M 50G
export USE_CCACHE=1
export LC_ALL=C
source build/envsetup.sh
lunch [COLOR="blue"]krexus[/COLOR]_kiwi-userdebug
make -j4 otapackage 2>&1 | tee ~/CAF/compile.log

Every ROM mostly will have its own vendor tree formatting, for Krexus-CAF, you'll need to create a new krexus_kiwi.mk so refer to the example there on how to create one. Eg. For AOKP, AICP, PAC-ROM

Building other Custom ROMs

Before you start syncing other custom ROMs, delete everything at AOSP or CAF folder except the hidden source code .repo folder ( To display hidden folders press Ctrl + H )

Sometimes, syncing new ROMs will fail then you'll have to delete all the other files & folders at the hidden .repo folder EXCEPT the project-objects & projects folder, these two are the actual source code folder, a repo init & repo sync then all the files will be extracted out again.

If you've got a very large HDD & would like to build multiple ROMs all at the same time then you'll only need to copy the hidden .repo folder over, Eg. Copy ~/AOSP/.repo to ~/AOKP, ~/AICP, ~/PAC-ROM & syncing it will only take awhile since all are using the exact same google source... :cool:

Any other thing that i might have left out then google it yourself... :cowboy:

Good Luck & Happy Building ! :cool:

Additional Tips

All custom ROMs manifest contains sources to build for almost all Android devices available while some of those sources are not needed for our 5x you can safely remove them by specifying at above kiwi.xml & it will save you not to download of more than 1GB of unused projects !

Our 5x uses msm8939 which uses the same source as msm8916 so you can also safely remove all the other unused apq8084, msm8937, msm8952, msm8960, msm8974, msm8994, msm8996 projects with the above single remove-project then re-specify back the projects that you need. Source Ref

Above are hardware not used on 5x, removing it will save you hours of downloading of these unused projects. ROMs are still buildable with these remove projects, there are still many projects not used that can be safely removed but i don't intend to waste my time on identifying every single one of them... :laugh:

Update 09 Sept 2016 - Everyone can also build their own ROMs

Old PC or laptop ? Slow internet connection, not a problem, gopinaidu77 has shared with me that he is able to build a ROM in just 25 minutes, rebuild a ROM after make clobber took just only 7 minutes ! Syncing any ROM source will only take 3 - 5 mins at 40 Mbps download speed !

Completely FOC, more info refer to here... :good:
