error: could not find libv8_libplatform library

[kelvin2200]

So, i've been reading through the other issues and posts, but nobody seems to provide a clear solution as to how to fix the above error;

Trying to install V8Js on a Debian distro, with PHP 7.0, using GN.

Did an apt-get upgrade, and installed all the deps.
Followed the instructions in README.Linux, but i end up with that compile error.

Please help

What's in config.log? Which version of V8 are you trying to build?

Same problem. Debian 8 x64, PHP 7.0.

Compiling myself from sources with fresh v8 in /opt/v8 ends the same. Looks like script is looking for libv8_libplatform library in wrong place. Or so I understood from looking script code.

well, i was trying to install v8js on a Kali virtual machine, couldn't find a solution, so i did a 'dist-upgrade' and i ended up messing the whole machine. now i got this:appstreamcli: symbol lookup error: /usr/lib/x86_64-linux-gnu/libxml2.so.2: undefined symbol: ucnv_close_57 reinstalling libxml doesn't seem to work... so i'm kinda stuck On Saturday, May 27, 2017 1:31 PM, semoriil <notifications@github.com> wrote: Same problem.

Ok, i'm officially going crazy... been at it for 3 days now. contents of config.log.

No reason to go crazy ...

V8 has changed signature of the CreateDefaultPlatform function which is checked for by the configure script ... and hence it wasn't found any longer.

Either pick a slightly older version, e.g. from 5.9 (beta) or 5.8 (stable) branch. 6.0 is dev branch anyways
... or wait until the issue is fixed, I'm working on it now, but don't know how much work is required (doesn't seem to be much though)

[stesie]

(accidentally closed the ticket, sorry for that)

[stesie]

Should be fixed with current php7 branch. Let me know, especially if it still doesn't work for you.

Otherwise I'll follow up with a release in the next days

Still having the same issue with php 7.1 ubuntu 16.04
