Description Jan Beich 2023-06-05 12:28:32 UTC

Ports with embedded v8 either don't build or don't run. Some like www/node* (bug 261952) can be worked around via USES=elfctl.

$ sysctl kern.elf32.allow_wx=1
$ sysctl kern.elf64.allow_wx=1
$ pkg install v8

$ proccontrol -m wxmap v8_shell
V8 version 10.4.132.20 [sample shell]
> ^D

$ elfctl -e +wxneeded `which v8_shell`
$ v8_shell
