Arch Linux User Repository

Some notes:

• 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).

https://gist.github.com/JanMarvin/61ee142b21c394f5c67a55df4f960adc by @JanMarvin allowed me to install the R V8 package. It would be great to incorporate the required changes to the main PKGBUILD here.

@marcs as you can see in other comments below this v8 package here doesn't work with V8 for R. See issue here: https://github.com/jeroen/V8/issues/58

• /usr/lib/v8 is not a standard linker paths.
• Even when trying to use your PKGBUILD with standard linker paths: /usr/lib/libv8.so: undefined symbol: u_strToLower_63

One solution would be to have another package on AUR that we would call v8-R or such. But as JanMarvin pointed out the best solution would be to make it work with this package, right?

What do you think?

hey @dflemstr,

I haven't checked that yaourt was dead, good to know thanks. This package is now compatible with aurman and yay.

I was not aware of the pletora of aur helpers nowadays, I personally don't use them, I just clone a package and build it with makepkg on a specific account designed to do that.

I would like to remind about this patch (which might be stale now...): https://gist.github.com/dflemstr/2c06e81da38420d29e702c5bd3601afc

Building does not work in a lot of cases now when prepare(), build() and check() are run in different phases, which is generally the case in AUR helpers such as yay, pacaur etc.

Note that both yaourt and pacaur are deprecated and yaourt has had a lot of security issues in the past (see https://itsfoss.com/best-aur-helpers/ for more info) so it might not make sense to recommend using those tools any more.

@znmeb you can limit the number of threads from your makepkg.conf file.

For the rest of the building errors you can change the version using one listed on the V8 branches from:

https://chromium.googlesource.com/v8/v8.git/+log/branch-heads/7.4

just change the pkgver variable and you are good to go.

This package is not suited for community IMO, the PKGBUILD is heavily documented to let it know the user that this package needs some configuration (sometimes), the default parameters is what i generally use and it should generally works.

I'm gonna update the PKGBUILD with the missing deps, thanks everyone.

I am installing this package but it cannot complete the installation.

I used the PKGBUILD from here: https://gist.github.com/JanMarvin/61ee142b21c394f5c67a55df4f960adc

This is the full installation report in my system: https://gist.github.com/jethroppaPH/6a40453cc262d32e99bdb3437accbefb

@zbraniecki you need to install the icudtl.dat file. Can be done adding this line to the PKGBUILD:

install -Dm755 $OUTFLD/icudtl.dat ${pkgdir}/usr/lib/v8/icudtl.dat

I tried to call new Intl.PluralRules(); and it crashed with:

d8
V8 version 7.2.502.25
d8> new Intl.PluralRules

I do have libicu installed. Is there a way to link it?

I'm testing it now - is there any way to limit the number of cores it uses? I have eight cores and it fired off 11 jobs and pushed my workstation so hard it shut down on a thermal overload!

Better yet - get enough votes to move the package into "community"

It's crashing in the tests:

I can run it again and post a full logfile if that's necessary.

Thank you for your confirmation @ramesesjd. My PKGBUILD disables the use of this libc++ (using use_custom_libcxx=false). I experimented with patchelf to fix the build, but in the end, why bother with a lib that is not required. Later I found that two of these flags (buildtools and libcxx) are used for the Arch chromium build as well, so maybe they could be adapted for the AUR v8 package as well? Not sure about the external_startup_data flag, the glib one is most likely not required.
