Hi!
I just recently decided to switch my AOSP build server because my old one was getting way too slow at building AOSP (it would take around 3~4 hours to build 6.0.1 with ccache). I upgraded from this:
Intel Core I3 2350M (4 cores, 4 threads)
8GB RAM
5400RPM HDD
To this:
Intel Core I7 6700HQ (4 cores, 8 threads)
16GB DDR4 RAM
5400RPM HDD
Unfortunately, after trying to freshly build CM13 for the oneplus one on my new system, it STILL took 3~4 hours to complete and I feel like this 5400RPM drive is completely bottlenecking my CPU. I wasn't hoping for any miracles to happen but I was aiming for a build time of around 1 hour...
Is this drive really destroying my CPU's performance?
Thanks for your feedback!

Hi,
I'm looking at building a new PC that will be dedicated to android development (ICS).
I only have a couple of questions:
1) is there much difference between compiling android on a i5 2500 or Phenom X4 or X6
2) How much hard drive space is recommend? i.e. is a 120GB SSD enough
3) Is 16GB of ram enough
Thanks,

More cores are better. Here are the requirements to build it from source:
- 6GB of download.
- 25GB disk space to do a single build.
- 80GB disk space to build all AOSP configs at the same time.
- 16GB RAM recommended, more preferred, anything less will measurably benefit from using an SSD.
- 5+ hours of CPU time for a single build, 25+ minutes of wall time, as measured on a workstation (dual-E5620 i.e. 2x quad-core 2.4GHz HT, with 24GB of RAM, no SSD).
Thanks for the answer - Just thought I would update on my experiences.
I use a Ubuntu 10.04 in VirtualBox (Windows 7 x64)
Core i5 750 @ 3.6Ghz
5GB Ram (for the Virtual - 8GB in total) DDR3 @ 1800mhz approx
4x 1TB Seagate HDDs in RAID 10
Takes about 1Hr 30min to build 4.0.3 using make -j4
It also uses less than 25GB for a single build
Hi Guys! I read somewhere that compiling need 4Gb Ram! ! ! ! Is it true? I have very old hardware so I'm going to buy a new hardware for start compiling....
thanks
No but it will take alot longer
I compile with 4gigs ram. A little less than 2 hours for full lunch build for 1 device. That's 2 .zips and kernel pieces on Linux Mint 12 no windows. I think those crazy big numbers are needed when you use a virtual machine.
if you dont know linux well id reccomend using ubuntu 10.04 too otherwise you have to mess around with things to get it to build unless they fixed the problems with newer gcc.
Just install Ubuntu 12.04 and build.
The "needs octo-core processor" and "needs infinite RAM" is all just bull****.
But 64-bits is better for building, as 32 - bits needs more packages to install etc etc. And 64-bits means you have more RAM.

I'm building on these specs:
Intel Core 2 Duo @ 2.2ghz
2gb RAM
Ubuntu 10.04 LTS
It takes around 3 hours to do a fresh build off of a make clobber but to do a rebuild on top on another one it takes around half an hour.
The more ram you have the less time for compilation..plus it also depends on architecture...i.e. i7...
compiling-time mostly depends on the processor.

I'm using a laptop with an Intel Pentium Dual Core T4200 with 4 GB of RAM. It takes a little over 3 hours to compile 4.0.4_r2.1 maguro (Galaxy Nexus GSM).
Same build time in Ubuntu 10.04 and Kubuntu 12.04. I just get more errors in 12.04 and had to do more tweaks in the makefiles.

A 2.5 quad? I think your slightly exaggerating. When I had a 3.5 quad it was slightly over an hour by a few minutes. You should run time with your build command after a make clobber.

Should be fine with the 4 gigs of ram, use ccache some decent swap, and you might need to shrink the java emulator size, also be sure to use 64 bit ics+
Here is a commit to help with the java emulator while building

It might work. But very less chance of working in machines less than 4gigs of ram. 4gigs of ram would be the minimum configuration.

It's always worth maxing your memory you'll notice good performance gains and will speed up compile times significantly. 4 GB should be no more then $20-$40 so it's a great upgrade for the money

More RAM?
It should he just about enough to make a ROM, but I think you should install more RAM to your laptop, just in case.
RAM should be fairly easy to install...
Good luck on making your ROM!

In order to compile ROM's (AOSP from source) and kernels (From source) you will need to use a UNIX based operating system such as OSX or Linux, personally I would recommend dual booting your laptop with Ubuntu 11.10 to maximize compatibility for compiling ROM's and kernels. For making apps you can use either Linux or Windows, and I would recommend using the IDE Eclipse for Android app development. As far as actually building your hard drive is a little small and could run out of space if you intend on building a bunch of different ROM's and kernels (A full set of AOSP builds is 80+ GB), and with 3 GB of memory compile times, will be pretty slow (For example to compile an AOSP build of Android 4.2 for the Nexus 4 would probably take around 5-8 hours, kernels will take anywhere from 1-2 hours probably) also if your laptop only has a single or dual core processor this will also effect compile times.
O.k. thanks for your reply sir.so could you recommend a Linux computer that I should buy as long as what specs should I get as far as how much memory,hard drive,etc.and out of curiosity what would a computer like this cost me.I want to thank you for your time and expertise. Take care!!!

If your just building kernels and some apps then yes, your laptop should be fine. For kernel development it's important to at least have a solid understanding of C, the Linux Kernel, and embedded development for that I would recommend the following books:
Practical C Programming: 3rd Edition
Understanding the Linux Kernel Third Edition
Embedded Linux Primer: A Practical Real-World Approach (2nd Edition)
As far as book for app building goes make sure you understand Java and XML, I would check out these books:
Professional Android 4 Application Development
Head First Java (3rd Edition)

Hi,
After compiling different ROMS I notices that during the proces, my 8 cores do max out, but my computerram 16GB in total is not used to it's full potential, it stays around 3 / 4 GB. Is this because we compile with / for 32 bit Android? I run a hard machine with dualboot ubuntu/windows 3770K processor, 256 SSD and 1 x 3 TB and 3 1TB harddrives.
ccache is also enabled and working, so i was just wondering why it would not use more computer RAM. while compiling a ROM.
Thanks
i know everything all how to make build i already pc but very old i,m thinking buy new lappy:laugh: anyone plz...suggestion. me what pc/laptop hardware requirements for custom rom building (ADV.. Thank You)
As much ram as possible, the more the better. Not sure of processor but the faster the better. As large a hard drive as possible. Compiling for use a lot of space. You'll need good cooling as well.

I've played with 16GB of RAM and it uses around half of it. Eight logical cores on I7 SkyLake fully utilized so more cores is more power. Also it eats almost whole 256GB SSD drive when using 50GB CCACHE. SSD is must have.
Also good Internet connection is helpful as it download almost 40GB of files on first repo sync.
P.S. all on Linux.
