Chromium Android build troubles...

[Ted Larson]

I have been trying to get an Android build of Chromium to go to completion using these instructions here:

https://chromium.googlesource.com/chromium/src/+/main/docs/android_build_instructions.md

It's blowing up with this error - looks like it is failing to build V8

ninja: Entering directory `out/Default'
[3/28844] ACTION //v8:run_mksnapshot_d...toolchain/android:android_clang_arm64)
FAILED: gen/v8/src/builtins/builtins-effects.cc gen/v8/embedded.S snapshot_blob.bin

Return code is -5
[10/28844] CXX obj/components/viz/service/service/compositor_frame_sink_impl.o
ninja: build stopped: subcommand failed.

It's interesting also because the system log is throwing this at the same time:

[9415835.830972] traps: V8 DefaultWorke[3175233] trap int3 ip:5bf95e06329d sp:77c1f17fe450 error:0 in mksnapshot[5bf959ff5000+448e000]

I used the instructions at the top of this post, so I am using that build configuration.  I suspect it's something wrong with my machine setup.  I don't think I am running out of memory or threads.  Any ideas of what to look at?

Thanks,

Hello,

I'm having the exact same issue/error since last month; last successful build for me was on June 6th.  Ted, have you found a fix?  Does anyone have a solution?  Please help.

Thank you,

Slava

Hi, 

In my case the solution was :

debug builds needs extra args.gn parmateres

  - v8_enable_debugging_features = false
  - v8_dcheck_always_on = false

for both release and debug "include_both_v8_snapshots = false" in args.gn.

The mksnapshot SEGFAULT-ed when executing "build step: __v8_run_mksnapshot_default___build_toolchain_android_android_clang_arm64__rule "./gen/v8/src/builtins/builtins-effects.cc""

Hope it helps.
