Thanks for quick reply! Unfortunately, it's the same. I ended up with hello world example after to trying out to use NewDefaultPlatform with php-v8 (https://github.com/pinepain/php-v8/blob/53a562e10c23e5f835b2ccdb20967f9c4aef529e/src/php_v8_a.cc#L34), which yield me there
/home/vagrant/.phpbrew/php/7.2-debug/bin/php: symbol lookup error: /home/ vagrant/php-v8/modules/v8.so: undefined symbol: _ZN2v88platform18NewDefaultPlatformEiNS0_15IdleTaskSupportENS0_21InProcessStackDumpingESt10unique_ptrINS_17TracingControllerESt14default_deleteIS4_EE With CreateDefaultPlatform it works just fine, and there was no other changes to sources except of using v8 6.5.116 and using NewDefaultPlatform. Bare 6.5.116 with CreateDefaultPlatform works fine.
