Indigo I use MAMP PRO for the MAC.
In MAMP I copied the ChartDirector files to the extensions directory and configured the php.ini file to load them.
I have tried the same in indigo, these are the steps I tried.
I found the directory for my stack by right clicking on the stack. (ie. ~/.indigo/stacks/8FA787/php_930E/lib/php/20210902/)
I copied the ChartDirector files to the to the above directory.
I then add "extension=phpchartdir810.dll" the the php.ini file using the Configuration overrides on the stack. BTW this is the same command I use for all my PHP environments. (MAMP, RedHat)
When I start the stack the following message is output to the log file. This is the message when using the files that were downloaded from ChartDir. It finds the file it just can't load it.
"[29-Jul-2022 21:08:00 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'phpchartdir810.dll' (tried: /Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll (dlopen(/Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll, 0x0009): tried: '/Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll' (code signature in <05D655A1-F3E7-3069-A59D-335552E13D52>; '/Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll' not valid for use in process: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?))), /Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll.so (dlopen(/Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll.so, 0x0009): tried: '/Users/croy/.indigo/stacks/8FA787/php_930E/lib/php/20210902/phpchartdir810.dll.so' (no such file))) in Unknown on line 0"
I have also tried to add Indigo to the System Preferences -> Security & Privacy -> Developer Tools list.
Thanks for your help. Please let me know if you have any questions.
