I have noticed that the build instructions on the AOKP website are a bit outdated. They date back to JellyBean. I would like to encourage other users to build more custom roms, and I thought that it would help if I show how to build one of the roms wich compiled successfully for me (Praise God!). It is my hope that these instructions are clear and easy to follow. Hey, if I can do it, anybody can do it!

<<<<< Step 1: Setup your system. >>>>>

To be honest, this can be the most daunting part, because if you do not set this up properly, it just will not work. I use Ubuntu 14.04 on a HP Compaq 6715b laptop. I know, not a very ideal compiler, but it is what I’ve got. Here are the suggested packages, just open a terminal and paste this in:

[CODE]
$ sudo apt-get install bison build-essential bzip2 curl dpkg-dev flex g++-multilib git git-review gnupg gperf lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev openjdk-7-jdk libbz2-1.0 libbz2-dev libc6-dev libghc-bzlib-dev libgl1-mesa-dev libgl1-mesa-glx:i386 libncurses5-dev libreadline6-dev libreadline6-dev:i386 libx11-dev:i386 libxml2-utils lzop maven pngcrush pngquant python-markdown schedtool squashfs-tools tofrodos x11proto-core-dev xsltproc zip zlib1g-dev zlib1g-dev:i386
[/CODE]

This will take a while. Once it is done, do this:

[CODE]
$ mkdir ~/bin && curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo && chmod a+x ~/bin/repo

$ gedit ~/.bashrc
[/CODE]

Now you should see gedit open up your .bashrc file, to which you should add this at the very end, and save it:

[CODE]
export PATH=~/bin:$PATH
[/CODE]

Now you need to close your terminal and open a new one to get the PATH variables to stick. Actually, it wouldn’t hurt to reboot your system after installing all of those programs we just installed. Your computer should now be primed and ready to go.

<<<<< Step 2: Download the source. >>>>>

Here is a very short project for you that takes the computer a long time to complete. Open a terminal and start typing:

[CODE]
$ cd ~
$ mkdir aokp6
$ cd aokp6
$ repo init -u https://github.com/AOKP/platform_manifest.git -b mm
$ repo sync
[/CODE]

You can now go outside, play with the kids, phone a friend, and then go to bed. When you awake the next morning, this might be done, depending on your internet connection!

<<<<< Step 3: Adding the device, kernel, and vendor trees. >>>>>

In some cases, you can simply type the command

[CODE]$ breakfast[/CODE]

and just choose your device, but at this time, the AOKP repository did not include a current device tree for the JFLTETMO phone, so we need to download one. I chose to test out the Dirty Unicorn JFLTETMO devices trees, by going here and choosing to download the zips. Later, perhaps we can learn about adding them as dependencies, but here are the links, be sure to choose the 6.0 branches and click the download button to download the zips:

https://github.com/DirtyUnicorns/android_device_samsung_jfltetmo
https://github.com/DirtyUnicorns/android_kernel_samsung_jf
https://github.com/DirtyUnicorns/android_device_samsung_jf-common
https://github.com/DirtyUnicorns/android_device_samsung_jflte
https://github.com/DirtyUnicorns/android_device_samsung_msm8960-common
https://github.com/DirtyUnicorns/android_device_samsung_qcom-common
https://github.com/TheMuppets/proprietary_vendor_samsung/tree/cm-13.0

Once you have downloaded them, unzip each one and rename them:

android_device_samsung_jfltetmo – jfltetmo
android_device_samsung_jf-common – jf-common
android_device_samsung_jflte – jflte
android_device_samsung_msm8960-common – msm8960-common
android_device_samsung_qcom-common – qcom-common

Go to you aokp6/device folder and create a folder called “samsung”. Now put the above folders into it.

Then unzip the kernel_samsung_jf folder and rename it “jf”. Go to the aokp6 folder and create a folder called “kernel”, go into the kernel folder and make a new folder called “samsung”, enter that folder, and put your “jf” folder here. Don’t worry, we are almost done.

Now go to your aokp6/vendor folder. Create a new folder called “samsung”. Enter the samsung folder and copy the contents of your unzipped proprietary_vendor_samsung folder. This should be a bunch of folders like jf-gsm-common, jf-common, etc. You actually don’t need all of these folders right now, but it will not hurt to have them, and there are two folders in there that you need.

Now you should probably take a break before going on to the next step!

<<<<< Step 4: Editing the device, kernel, and vendor trees. >>>>>

Now, go to the device/samsung/jfltetmo folder and rename du.mk to aokp.mk and edit it as follows:

[CODE]
$(call inherit-product, device/samsung/jfltetmo/full_jfltetmo.mk)

# Enhanced NFC
$(call inherit-product, vendor/aokp/configs/nfc_enhanced.mk)

# Inherit some common DU stuff.
$(call inherit-product, vendor/aokp/configs/common_full_phone.mk)

PRODUCT_BUILD_PROP_OVERRIDES += \
PRODUCT_NAME=jfltetmo \
TARGET_DEVICE=jfltetmo \
BUILD_FINGERPRINT=”samsung/jfltetmo/jfltetmo:4.4.4/KTU84P/M919UVUFNK2:user/release-keys” \
PRIVATE_BUILD_DESC=”jfltetmo-user 4.4.4 KTU84P M919UVUFNK2 release-keys”

PRODUCT_NAME := aokp_jfltetmo
PRODUCT_DEVICE := jfltetmo
[/CODE]

NOTE: the original file said “vendor/du/config/*” you must change it to “configs” or there will be an error!

Then, in the jfltetmo folder, delete the cm.dependencies file. Do the same deletion in all of the device/samsung/* directories. You don’t want to download CM dependencies, because you already have them here.

Note: Because repositories are constantly updated, I can only garuntee that this will work based on the files as they were the day of this writing. However, with all of this in place, if you follow this guide, it should work realatively the same as what happened for me.

You can actually just run the compiler right now, however, you will have several stop errors that we plan to address here before you do that. All of these edits are due to errors that cropped up when running the compiler.

The first error was relating to libhealthd. Android and AOKP source already has a built in libhealthd for the qcom motherboards, and it is a duplication of efforts (which causes an error) to have both the device tree libhealthd and the source libhealthd. So here is how we fix it. Now, go to the device/samsung/qcom-common/libhealthd folder, and make the following changes to the Android.mk file:

[CODE]
# WJH LOCAL_PATH := $(call my-dir)

# WJH include $(CLEAR_VARS)
# WJH LOCAL_SRC_FILES := healthd_board_default.cpp
# WJH LOCAL_MODULE := libhealthd.qcom
# WJH LOCAL_C_INCLUDES := system/core/healthd bootable/recovery
# WJH include $(BUILD_STATIC_LIBRARY)
[/CODE]

Another error that will crop up if you run the compiler now, is that your multi-media video will have a problem setting the picture order, and the compiler will get confused and stop with an error. So we can fix that here before we begin. We need to edit one of the hardware files. Go to hardware/qcom/media-caf/msm8960/mm-video/vidc/venc/src, and edit the video_encoder_device.cpp file as follows (this is the last few lines of the file):

[CODE]
bool venc_dev::venc_set_picture_order_count_type(OMX_U32 type)
{
// WJH venc_poctype temp;
// WJH venc_ioctl_msg ioctl_msg = {&temp, NULL};

// WJH temp.poc_type = type;
// WJH DEBUG_PRINT_HIGH(“Setting poc type: %d”, type);
// WJH if(ioctl(m_nDriver_fd, VEN_IOCTL_SET_PIC_ORDER_CNT_TYPE, (void *)&ioctl_msg) < 0)
// WJH {
// WJH DEBUG_PRINT_ERROR(“Request for setting poc type failed”);
// WJH return false;
// WJH }
return true;
}
[/CODE]

And finaly, there is an error that will pop up and stop your compiler because of a conflict over the “ambientIsAvailable” portion of this file: packages/apps/InCallUI/src/com/android/incallui/ModButtonPresenter.java at line 404. So we will just go ahead and edit it here before we begin.

[CODE]
final boolean showNote = isProvisioned &&
// WJH DeepLinkIntegrationManager.getInstance().ambientIsAvailable(getUi().getContext()) &&
mNoteDeepLink != null;
[/CODE]

Now that all of the hard work is done, it is time to actually build something!

<<<<< Step 5: Start your build! >>>>>

Phew! You have invested a lot of hours into this project, now it is time to actually put those files and time to use! Open up a terminal in your aokp6 folder and start typing:

[CODE]
aokp6$ . build/envsetup.sh
[/CODE]

Which will output something like this:

[CODE]
including vendor/aokp/vendorsetup.sh
including sdk/bash_completion/adb.bash
including vendor/aokp/bash_completion/git.bash
including vendor/aokp/bash_completion/repo.bash
[/CODE]

Now type:

[CODE]
aokp6$ brunch jfltetmo
[/CODE]

Which will start the long build process, it will output this:

[CODE]
including vendor/aokp/vendorsetup.sh
Got local manifest
Got local manifest

Notice that there were some “warning” flags in there. Warnings are not all bad, but they can be. In this case it works out okay. Hopefully, after many hours, you should see this:

Success! Praise God! Now you can put this on your phone and test it out! Hopefully everything will be working! For future use, now you can start making changes or edits, from backgrounds to kernels! Have fun and make lots of backups. Remember, sometimes it is really hard to undo a change that you make.

Hopefully we learned how to set up our system, get the source, add devices and kernels that are not in the source, make proper edits, and run the compiler. Like I said, this works on my machine, as of this writing. You may notice, that if you make this build, it will not be identical to the one that I have posted on XDA. That is because I have made a few edits, additions, and/or subtractions here and there. That is the great thing about Android and open source! It is now up to you to make it better, to make it unique, or to make it you. Good luck with those builds, and be sure to share and help the next guy or gal with thier projects too!

Linux – keep it simple.
