Recommendations

1. Before installing this package, install depot-tools-git and follow its instructions.

2. To speed-up compilation, build on tmpfs and disable tests:

BUILDDIR=/tmp/makepkg makepkg --nocheck

Or using yay:

BUILDDIR=/tmp/makepkg yay -S --mflags --nocheck v8

@teddy_coder You need https://chromium.googlesource.com/v8/v8/+/035c305ce7761f51328b45f1bd83e26aef267c9d

@mayweed @gnaggnoyil You need https://chromium.googlesource.com/v8/v8/+/7c90567a34c01fdddce465e57a8040ef35d6f5bd

Apply these patches after gclient sync -D -r "$pkgver".

(Is there an easy way to download a patch directly from chromium.googlesource.com?)

I also had to downgrade Python to 3.9 as from collections import Mapping no longer works in Python 3.10, though this is possibly because I was building the older v8.5.210.20.

I'm having the same issue @mayweed encountered. Was using yay.

Hello I’m just trying to build v8 via this package, here is the error i got :

../../src/base/platform/platform-posix.cc:790:59: error: comparison of integers of different signs: 'size_t' (aka 'unsigned long') and 'long' [-Werror,-Wsign-compare] if (stack_size_ > 0 && static_cast<size_t>(stack_size_) < PTHREAD_STACK_MIN) { ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~ ../../src/base/platform/platform-posix.cc:791:19: error: implicit conversion loses integer precision: 'long' to 'int' [-Werror,-Wshorten-64-to-32] stack_size_ = PTHREAD_STACK_MIN; ~ ^~~~~~~~~~~~~~~~~ /usr/include/bits/pthread_stack_min-dynamic.h:26:30: note: expanded from macro 'PTHREAD_STACK_MIN'

Any ideas? Thx

I got the same problem as bashee_wang in previous comment. I solved it by chown for directory /opt/depot_tools/. But then I got an error while compiling:

The --mflags "--nocheck" did not work and the check() step failed because of some tests.

To fix it, edit the PKGBUILD and replace the contents of check() { ... } with just check() { echo "hi" } (if using yay, pass in --editmenu and select to edit the PKGBUILD once asked)

I had some weird building problems with the last few versions that didn't allowed me to update this package. I tried some tests on a standalone environment but I couldn't fix them. Since someone filed for an ownership claim and got approved by AUR I will stop supporting the package and let someone else try. Good luck and have fun.

Some notes: * Latest version is based on the version on branch-heads from the V8 repositories, I stick to stable, but sometimes I could use beta but I never use dev (check this: https://omahaproxy.appspot.com/). * This is a "generic" configuration, v8 is highly configurable, if you need v8 for some specific integration please check the Google documentation. * Prefer yay/aurman instead of yaourt/pacaur. * Gclient has to download the whole V8 repo, it takes some time to complete (depending on your internet connection). * This package requires around 3/4 gigs of space so be sure to have a large enough /tmp partition if you use yaourt, also be aware that aurman/yay/pacaur will save this package in ~/.cache/(aurman|yay|pacaur)/v8, so be sure to have a /home partition with enough space. * The build and testing process takes some time, I recommend to use at least a 4 cores with 8 threads cpu, better an 8 cores 16 threads cpu. * If you have at least 32GB of RAM you can use a ram partition to speed up the build process (yaourt uses /tmp by default).
