Compiling Tinkerboard's Android

[lobo]

There's components called Vendor Images starting in Android 7+, which contain vendor specific implementations and executables. The main system image contains references and checksums for the vendor images. If the vendor image doesn't match up with exactly what the system image expects it will toss this dialog up.

Thank you, I havn't known this before. So I have this message also with full image compiled and flashed as your guide, but not with the ready image provided by Asus. Maybe I need to clean the sources and build the image again...

Assuming you started from scratch, on your virtualbox (do not try to transfer stuff over from your windows build, that's completely invalid build objects).
execute the following commands and show me the output (pastebin or uploading a file will work).

Code:

. build/envsetup.sh && lunch rk3288-userdebug
make clean && make

Ninja can fail sometimes if you're using more threads than you should. Please ensure you are listening to the note of caution i made on thread counts. You should probably be using -j4 or so for the build.

I've tried without -j and with -j4 but the problem is always the same :/
Here is my full output:

EDIT:
I've tried with a fully new ubuntu install and it worked!

Compiling system image (~50 minutes at -j28)

AFAIK the -j is related to how many jobs a computer can take. Suppose to have a I7 CPU, there could be 8 threads available . I suspect that the PC can't do more at once and it may cause unresponsiveness to the system. Unless we use to share the compilation load by distcc

hello kbungo & Im4Tinker,

first.. Many thanks kbungo, for this write up.. 
It's going to keep me busy for a while.. ;- ]]....
so.. I'm using a Lenovo Ideapad G560, 
Intel Core i5-540M, (dual core, 4 threads ) with 8GB Ram.. 
I've.. removed the DvD drive and install HDD caddy with 1TB HD ]]..
lots of space for the source code.. now...
so.. just a point to clarify...

Just give it a shot and see how long it takes... Android was never meant to be fast to compile on non-high-powered machines! The first build will take a long time, but subsequent builds can take as short as a couple of minutes. It's a one time cost (as long as you don't do a clobber!)

To decide the size of -j, it is reccomended you run "lscpu" in bash. You will see a ot of output, but you want the value of 3 things: "Thread(s) per code:", "Core(s) per socket:", and "Socket(s):".
Multiply those 3 numbers. Supposedly you can run about 100%+1 of that amount of threads, but in my experience, using about 75% of that amount is best... If you've got 2 Threads per core, 4 Cores per socket, and 1 Socket(s), then that's a maximum of -j9, but I'd reccomend around -j6

I deliberately left this out of the tutorial because I was already afraid it would be cluttered and this information can be found through google easily. (Google: "make j count")

Yep, that's super common. I had the same issue after a fresh pull of the source. Just give it a good

Code:

make clobber

and build it again. It'll take a long time, but should be okay this time. I don't fully understand it, but it works.

Fixed by running `export LC_ALL=C` before compiling the kernel.
