| Workarounds for building Q on 8GB RAM environment: | |
| 1. At the start of the build: | |
| [ 99% 138/139] /mnt/ssd/aosip/out/soong/.bootstrap/bin/soong_build /mnt/ssd/aosip/out/soong/build.ninja | |
| This used to take around 30mins, after enabling zram now it takes around 30secs (thanks to @kdrag0n for the zram idea) which is on par with what happens in 16GB RAM building environments | |
| sudo apt install zram-config for installing zram-config package | |
| sudo nano /etc/fstab and add a # in front of the swap disk if you have one and then reboot | |
| After booting cat /proc/swaps to check if zram is enabled or not | |
| 2. To avoid huge metalava compilation times, compile the api-stubs-docs and other packages manually first then continue with mka bacon etc | |
| For example this is what I'm using now in aosip: | |
| . build/envsetup.sh && lunch aosip_wayne-userdebug && mka api-stubs-docs && mka hiddenapi-lists-docs && mka system-api-stubs-docs && mka test-api-stubs-docs && mka kronic | |
| Each of those api-stubs-docs, hiddenapi-lists-docs etc took around 4-7 mins | |
| Increasing of heap from soong directory or other env exports are not required | |
| Total combined build time in my system (Ryzen 1600 with a 8gb ddr4 stick) is around 2hrs now compared to 5hrs previously | |
| For errors while building metalava check #metalava |
Any ideas how I can run the AOSP Build with 6GB ?
On my system (Ryzen 3 3300u) 2.1GB is occupied by the GPU and there is no BIOS option to reduce it :(
I read somewhere that we can disable the documentation build altogether..Btw,
I also saw this suggestion to improve compile times..

Buy more RAM 🤷♂️
