Hello,

I try to compile v8js, but i have this error :
checking for V8 version... NONE
configure: error: could not determine libv8 version

Any idea ?
Thanks,
Nico

Could you please elaborate on what exactly you try to do and what you already did (from/compared to README.Linux)?

Especially

  • what platform are you trying to build on? GNU/Linux?
  • did you compile V8 yourself? how did you do that (snapshots? shared lib?) and how did you install?
  • which options did you pass to ./configure?

Hello,

On CentOS,
I try with EPEL and from github source

i try with :
./configure
./configure library=shared
./configure native
./configure native library=shared

See https://github.com/phpv8/v8js/blob/master/README.Linux.md

You first need to install an appropriate version of V8; to do so you probably want to build it yourself and install as needed; If you're unsure which version to pick, I'd recommend latest version of 4.6 (stable) line, currently this would be 4.6.85.25
... if new enough and well maintained you might pick the version from your distro, make sure you use 3.24.10 or newer.

Afterwards you need to compile V8Js itself, its a whole different step (as per above README.Linux.md) file

The commands you state are a mixture of both, aren't they?

The "library=shared" and "native" part belongs to building V8 itself, but must be passed to make there.

"./configure" is needed with V8Js, but there are neither native nor library=shared flags

I got the same error on ubuntu 12.04
I compiled v8 myself - 4.6.85.25

I tried with and without the opt/v8 trick but without luck.

./configure --with-v8js=/opt/v8

@yograf please provide

  • output of find /opt/v8 command
  • config.log file

How did you compile V8 on precise? AFAICR it doesn't ship a c++-11 capable compile with it

@stesie thanks.
I don't remember any error while compiling V8.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.68. Invocation command line was

$ ./configure --with-v8js=/opt/v8

configure:4777: result: NONE
configure:4800: error: could not determine libv8 version

... so g++ fails to compile due to stuff in v8.h

Which version of g++ do you use? (g++ --version)
I'd assume something old like 4.4 that doesn't support the c++11 standard well enough

V8 brings a pre-compiled clang version with it, which doesn't work on vanilla precise. Hence my question in the last post, since it requires glibc 2.5 or higher (AFAIK, not checked again for now)

cheers

@stesie, Nope, g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
But I guess you're right and precise is too old.
I'll try Trusty.

@stesie what exactly version of g++ i need? Im getting same error. g++ is v4.8.4

@ridersx which error do you get? The error: expected unqualified-id before 'using' or just checking for V8 version... NONE (which is caused in any case when it cannot figure out how to compile/link against libv8)

g++ version 4.8 should be fine; I'd suppose you have a different issue...

Please share the config.log file.

@stesie it's checking for V8 version... NONE. I will show config.log tomorrow, it's on work machine.

@ridersx the actual problem is

configure:4838: ./conftest
./conftest: symbol lookup error: /usr/lib/libv8.so: undefined symbol: _ZTVN6icu_5413UnicodeStringE

... this is your libv8.so references a (undefined) symbol expected in libicuuc.so.

I suppose you compiled V8 and let it build its own version of libicu. However then just copied over libv8.so to /usr/lib.

So either copy over the other libicu*.so files (which might be problematic) or compile V8 against the installed libicu by export GYP_DEFINES="use_system_icu=1" before make of V8 (and then copy libv8.so once more)

See https://github.com/phpv8/v8js/blob/php7/README.Linux.md for a walk-through on how to install V8.

I have the same problem, only under Centos 6.6

checking for V8 version... NONE
configure: error: could not determine libv8 version

CentOS release 6.6 (Final)

checking for V8 version... NONE
configure: error: could not determine libv8 version
ERROR: `/var/tmp/v8js/configure --with-php-config=/usr/bin/php-config --with-v8js' failed

Please, help.
Tell me if you need more some information

PS

whereis libv8

@matrixua please open new bug reports for new topics (the "could not determine libv8 version" message is just so very generic and usually caused by mis-installations of V8).

Please attach your config.log file which should have a detailed error message.

Anyways, please see issue #204 regarding CentOS 6.6 - it's pretty outdated and you will have to statically link V8Js against PHP, which involves compiling PHP on your own.

the same problem
any idea?
This file contains any messages produced by compilers while
