When compiling v8js against PHP 8.4.0RC3, I got the below error: ``` /tmp/v8js/v8js_object_export.cc:678:9: error: ‘php_strtolower’ was not declared in this scope; did you mean ‘php_strtok_r’? ``` I found the below change in PHP: https://github.com/php/php-src/commit/85e6688791771f4af575de2421e4f9c1638805a5 Also, I found this reference: https://github.com/Imagick/imagick/pull/690 I tried a quick test and changing v8js_object_export.cc to call zend_str_tolower instead of php_strtolower seems to work. Thanks for your help.
