Build time

I use AWS Ubuntu 14.04. C4.xlrg. 16 cores with 30gigs of ram.

DU Lollipop - 40mins without ccache, 15mins with.

AOSP Lollipop - 25mins with ccache.

CM12 - 17mins.

All builds are for FLO. Nexus 7 2013.

[Android] smac0628:
I tried with the c8.2xlrg and make -j64 with very little improvement. Took my DU time to just above 11mins. But that costs $1.68 per hour. So I settled on the c4.xlrg for $0.86 per hour. I can keep storage for $0.10 per GB per month so I have 250GB storage and just spin it up do a repo sync and build and can get in and out in less than 45 mins. Usually closer to 25 or 30. So cost wise looking at $25 base for storage and however much hourly I use per month. Last month was $40 and this month will be close to $60. I've been playing a lot more. [emoji5]

I am compiling my first android (AOSP master) build with an DigitalOcean instance right now.

16GB 8CPUs, make -j32. For now it is 60min in and it is still building.

Costs: $0.238 / hour

Building a script right know which spins up my instance and builds my repo without thinking too much about it. Cloud is a great idea. ;)
[Android] Abhinav1997:
j32?? Are you sure your CPU supports that much threading? Run this command-

cat /proc/cpuinfo | grep "^processor" | wc -l

on your server and see the number it gives for output and use only that much. Using more jobs than supported would rather slow the builds down.

[Android] kikusz:
just wondering...WHY on earth would you ever need to have a 13gb swap?

a traditional distro will use under 1gb for everything assuming you're not inside a wm like gnome/plasma...

compiling something like android 7 will take about 4gb ram without any -j options add about 500mb for each parallel cc

assuming a traditional build quadcore with 8gb ram gcc wouldnt even touch the swap

and if you had like 16gb ram or more..then I wouldn't even use swap...

think of swap as "emergency memory" and this is what your system does...lets say it reaches 95% ram check for a mounted swap partition...if there's one use it..if there's none..start clearing the oldest cached ram

now here comes the dilemma...

"would my system be faster if I had a 30gb swap or force it to clear the cached ram"

the answer is basically the amount of ram you got..if you have a recent computer with something like 16gb using a swap partition will only slow down your computer if it ever needs it, as swap is lots slower tham ram since its hard-drive based

assuming you got 16gb and ram fills up..your system will create a "trash" scenario once it reaches a certain point

and clear lets say 5% of the total cached ram..this will take let's say 1-2 seconds until the os clears it..either flushes to disk (pax/laptop-mode) or unused cached ram stored for reusage...the system might process some of the stuff again since its no longer in ram but the speed of cpu+ram vs cpu+hard-drive(even ssd) wouldn't compare specially if you're building a huge project like android

if you want a perfect setup...you might just want to get like a

1tb ssd..

whatever cpu you can afford (with the highest cache you can afford)

get a linux distro like gentoo or whichever you can rice up on CFLAGS

and the little trick would be something like 32gb or more and setup ccache on ramfs

24GB RAM

Win 7 64b

Multiple drives

Oracle Vitual Box

LOS 13.0

Assign VBox all "8" CPU's, and 12,288MB RAM

3 Storage devices on separate physical drives

System=>Windows Dynamic 2 drives RAID 1 (ie software RAID) , mechanical devices are 7200RPM

CCACHE=>2 disk RAID 1 Solid state Drive (5GB only uses 2GB, but 50GB configured in buid)

BUILD_OUT=>2 disk physical RAID 1, mechanical drives, 7200RPM

Build Time around 35min

I also have another virtual Box for building Nougat based ROM's

Assign VBox all "8" CPU's, and 12,288MB RAM

1 Drive sitting on an old USB 2 (ie slow interface and slow drive). I would guess its only 5400RPM with little on-board cache

Build time 90min

I recently created some more disk devices on this test system I started with

3 Storage devices on separate physical drives

System=>Still the USB2 portable mechanical hard drive

CCACHE=>A faster USB3 mechanical HD, I am guessing 7200RPM with some decent on-board cache (its pretty fast for a portable drive)

BUILD_OUT=>2 disk physical RAID 1, mechanical drives, 7200RPM

Making the above change cut the build time to around 45min. even now, the build out drive seams to me to be the "bottleneck" in the speed of the process. But I am a little surprised that its now close to the system sitting on an internal drive (as opposed to a slow USB2 portable drive)

-Nvidia gt-240 1gb ddr5

And Ubuntu 16.04

So what do you think can it build something with it or not?

Because is stayed like this for 2 years doing noting so what do you think to do with this PC if it cant build ROMs?
[Android] DiamondJohn:
Its going to be SLOW, ie hours, maybe double digits. But simply kick it off at night and check the results the next day. Maybe start it off in the afternoon and check it later the following day, or maybe even the day after...

This looks like your bottleneck/stopper from using this PC to build ROMs. I have plenty of RAM, so not sure what the min limit is, but I am sure I have read many talk of having issues with anything below 4GB. maybe search the following thread for "4GB" https://xdaforums.com/chef-central/android/guide-android-rom-development-t2814763

Its enough, but expect slow builds with a single drive. I actually use USB drives in addition to my main drive(s). eg the out directory is a different drive to the ROM source and the system drive and the CCache are separate drives again.

I actually use a virtual PC inside VBox and only assign 128mb to the video; and that's probably being very generous. Its basically all done in a shell window.

That is what is the norm for Nougat and Oreo based ROMs

It may be possible, but it would certainly not be easy.

Way beyond the scope of a thread like this.

How is the build time on a Mac?

Do you think it's cause of the ram or the CPU?

& What would you say about a i7 8700k 6 core cpu w/hyperthreading?
[Android] DiamondJohn:
I cut my build time in half by moving different parts of my disk onto different disks/spindles, even including a USB3 drive. NB I am running on a virtual box in windows.

Without distributing the disk load, the CPU wasn't reaching close to 100%, because it was waiting on the disk.

I am running a Core i7 2700, quad core Hyper-threaded, 3.5GHz O'C to 4.4GHz, 24GB. With all 8 cores (ie real and virtual) at about 95% CPU and 12GB assigned to the VBox, and take about an hour for Oreo. Less for lower androids.

I really found and am still finding. its my disks that are the bottleneck. NB Most are raid 1 so not slow, and ccache sits on an SSD. I haven't tested lowering the assigned RAM, as its just there for the taking

solution

Get rid of busybox and use voodoo rootkeeper

works on rooted tf300

software looks for "busybox", "su" and "superuser" in following folders:

sbin/

system/bin/

system/xbin/

system/app/

data/local/xbin/

data/local/bin/

system/sd/xbin/

The check is performed only on app start, if you can't install, then you have a corrupted apk file (the zip-apk one mentioned in this topic is faulty) or something wrong with the device.

I bet questions asking how to make full world from demo will come shortly.

Basically... Overwrite files from termcharts to proper directory in jepp folder, start as a demo.

(you only need to overwrite, no need to add rest of the files)

Where to get new charts?

O c'mon it's everywhere (try the site with a big ship on it ;]), but Russians are usually 0-day with updates (if you followed my last post you know already where to look ;]).

Program says device not supported?

Clean program cache or restart the device.

[Samsung Galaxy Tab Plus] wlaziu:
If you get a "don't work on rooted devices" then you have files that the software looks for.

I posted earlier for what and where it looks for.

Root your tablet and check those folders, erase (or rename) files as necessary (Make a root backup before commencing, and erase su as a last file).

Get rid of folders that are empty.

One more thing. I did that on a stock OS (only rooted). If you have any non standard OS (Cyanogenmod, flashed rom etc, then your mileage may vary)
[Samsung Galaxy Tab Plus] hk9090:
Thanks for your method. I am really stuck here as my device is rooted. If I unroot it I am unable to remove the system protected files you described in your earlier post. Installing Voodo Rootkeeper and then trying to remove the system protected files gives me a "files cannot be deleted" error message.

Could you describe the method you used to erase those files?

Thanks!!
[Samsung Galaxy Tab Plus] wlaziu:
Before you will be able to edit rooted folders you have to "remount the system directory for r/w access" normally it's in a r/o state.

I personally use Total commander, it's free and has all the needed tools (including remount).

You can also use specialized software for this task, for example root explorer, but it's a payware.

Do you change it using LCD Density? Which value did you use?

I use the pro version, but it works with the lite version.

1) Look for "build.prop" in performances.

2) After that in options "build.prop tweaks"

3) " LCD density"

4) Put 190 and reboot.

Worked like a charm.

Just changed LCD density, put maps on right folder and every thing worked.
