How do you build your AUR packages? To remove the source download, just delete it from wherever it is being downloaded to.

No luck, I have installed the v8-3.14-bin package, starting from a a fresh install maybe there are some quirks.

BTW how to remove the source download?

I don't know why it is not validating for you. Everything works on my end and the checksum in the PKGBUILD is correct. Try removing your source download and start fresh, if you haven't already.

Error is generated by the validation of the zipped sources

v8-3.14.5.tar.bz2 ... sha5sum not correct

@artemklevtsov I added a CXXFLAG to build with gcc 10. Should work now.

Build fails with the following error:

@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.
