which version of V8 is this?

I recently tried 10.1.124.12 which worked just fine, but haven't tried the 10.2 line so far

[usback]

i found problem with v8 more version 10
9 version is working
thank you..

@stesie

hi there,

Trying to compile v8js with PHP8 .0.20.

Comipiled V8 main branch (V8 version 10.5.0) without errors. Listing of ls -al /opt/v8/lib matches usback's.

However, building v8js explodes with the same message:

checking whether g++ accepts -g... yes
checking how to run the C++ preprocessor... g++ -E
checking for C standard version... c++14
checking how to allow c++14 narrowing... -Wno-narrowing
checking for libv8_libplatform... found
checking for V8 version... NONE
configure: error: could not determine libv8 version

[temuri416]

I can also confirm that v8js compiles just fine with V8 10.1.124.12 - and huge thanks for that.

@stesie Is there a chance to look into 8.1 compatibility? :)

EDIT. v8js compiles just fine with PHP8.1

[usback]

thank you !!! i will try that version

[stesie]

Try PR #490 for V8 10.5 support on PHP 7.x and please report back if it works for you.

If so I'll merge it (and forward merge it to PHP 8.x branch)

[usback]

os: ubuntu 22
php : version 8.1.7
v8 : version 10.1.124.12
it worked
but i'm not try php7.x version
thank you

[usback]

php7 is not work ...
configure is pass but make has problem

thank you

[redbullmarky]

@usback this might be entirely useless for you, but having had similar errors, make sure you're starting from a clean slate when you're building for different versions of libv8, php, etc.

$ make clean

i had a LOT of issues, failed tests, etc until i did that.

otherwise, the output in your last comment is chopped off and doesn't show the error, just the subsequent details for it.

[svowl]

@stesie Could you, please, confirm that V8 v10.1.124.12 is the last one which is compatible with v8js php8 branch?
I just tried the last stable V8 release 10.5.218.7 (at this moment) according to https://omahaproxy.appspot.com/ and it failed in the same way as described above (configure: error: could not determine libv8 version)
