Hello Everyone, |
2 |
This week, I started managing the structure for the modified LineageOS |
3 |
fork we would keep. Namely the modified `repo-manifest` [1] and |
4 |
`llvm_android` [2], for now. No patches have been applied to them yet |
5 |
for the reasons discussed below. |
6 |
|
7 |
My plan for this week was to start with patching the `llvm_android` |
8 |
build scripts. Android uses a prebuilt Clang (bundled with the repo) |
9 |
among other stuff to build the toolchain. So I had to emerge Clang on my |
10 |
phone. |
11 |
Emerging Clang turned out not to be a breeze when I have a phone with 3 |
12 |
gigs of RAM. So for about the longest time, I was busy trying to make up |
13 |
for it. I tried setting up distcc, increased swap/zram, but still the |
14 |
OOM killer got me. |
15 |
Later last night(/day), I came across the tips for building clang/gcc in |
16 |
an embedded Android environment at [3]. So I followed that and as of |
17 |
now, me writing the mail, OOM has not got me, Clang is emerging. |
18 |
|
19 |
While I considering the patching part easy, I guess the major bottleneck |
20 |
in the process of building Android natively would be the compilation. |
21 |
Essentially I will have to trade time for memory. I will also give |
22 |
another shot to distcc while I am at this. |
23 |
|
24 |
Regardless of problems I faced, I made "TODO" comments in the source and |
25 |
wrote notes about where to patch the build scripts locally. I avidly |
26 |
wait for Clang to compile and then start testing the patched build |
27 |
script. |
