Arch Linux User Repository

I had to add -Wno-error=stringop-truncation -Wno-error=array-bounds to CXXFLAGS to build with GCC 9.

For reference, I was able to build this with gyp (20170609-2) in the main repository instead of gyp-git.

@znemb Thanks for the info. I updated the package using the fix by @sjewo (thanks!). It should build successfully again.

GCC 8 introduced some new error checks.

Alter line 72 in PKGBUILD to

export CXXFLAGS="${CXXFLAGS} -fno-delete-null-pointer-checks -std=c++98 -Wno-class-memaccess -Wno-cast-function-type"

to disable them.

This does not build, and the R "V8" package does not work with the v8-3.14-bin package at the moment. I'm looking for a workaround.

Sorry to say I'm disowning this package, I don't have time to get this building again.

I did, however, package v8-3.14-bin from ubuntu, and have uploaded that to the AUR now at https://aur.archlinux.org/packages/v8-3.14-bin

The gcc 6 patch doesn't fix all segfaults. Compiling with gcc-49 works for me.

I altered the PKGBUILD to include the gcc 6 patch (I also changed the source and added a dependecy to gyp-git).

You'll find the code here:
https://github.com/jeroenooms/V8/issues/32#issuecomment-274110406

To run d8 and I assume v8 the following patch is required to be able to use this with gcc 6: https://bugzilla.redhat.com/attachment.cgi?id=1164037

I applied the patch and many more (http://pkgs.fedoraproject.org/cgit/rpms/v8-314.git/tree/) and can provide an updated PKGBUILD, but I do not know anything about v8 nor do I use this package so dunno :)

I am unable to build this package since the gyp repository has moved from svn to GitHub.
