System requirements to build AOSP

[David.Warburton]

I'm trying to get an idea if my spare computer could build android
AOSP or would choke, it's a 1.8ghz single core system with 768M RAM.
I'm sure it would be pushing it. If this doesn't cut it, what is
recommended hardware? What is minimum hardware? Thanks!

A slower computer will just take longer to build. What cuts it is dependent on your patience.

A usable starting point is a quad-core with 4GB of RAM (but you're
still looking at hour-long builds). With less RAM than that, it
becomes hard to use all cores at the same time as the system starts to
swap. With less than 1GB, you're likely to see your machine crawl to a
halt even with a sequential build, as some individual build steps
require significantly more RAM than that.

I have seen several times machines dying when building the Android framework. One we found was running out of memory (and did not have any swap setup), the other we just reinstalled Ubuntu after scratching our heads for a couple of days...

Any good solution or good story for parallel builds ? Using distcc ? anything else ?

Thanks,

Matthieu

The basic requirement is RAM >= 2G  .

One major memory hog I've seen is the javadoc processes which seem
to clock in at about 400 MB each. Avoiding SDK builds, then, will
probably help reduce choking.

[Anthony]

On a related note, I replace "javadoc" with "true" in build/core/droiddoc.mk. Speeds up builds and presumably lowers RAM usage.

You can change variable BUILD_DROIDDOC to some empty file.
./build/core/config.mk:69:BUILD_DROIDDOC:= $(BUILD_SYSTEM)/droiddoc.mk

Or comment " include $(BUILD_DROIDDOC)" statement in ./frameworks/base/Android.mk
./frameworks/base/Android.mk:477:include $(BUILD_DROIDDOC)
./frameworks/base/Android.mk:513:include $(BUILD_DROIDDOC)
./frameworks/base/Android.mk:549:include $(BUILD_DROIDDOC)
./frameworks/base/Android.mk:574:include $(BUILD_DROIDDOC)
