For the love of my life, I cannot figure this one out: I’ve compiled xdebug from source code and while the CLI will show me that it is active the webserver will not.
This is the process I went through.
JavaScript
x
phpize ./configure --enable-xdebugmake make installmv `compiled module` `desired location` Then I edited php.ini to include:
JavaScript
zend_extension=/usr/local/php/extensions/xdebug.soxdebug.default_enable=1xdebug.remote_enable=1xdebug.mode = developxdebug.log_level = 7xdebug.var_display_max_data = -1xdebug.cli_color = 1;xdebug.var_display_max_depth = -1xdebug.collect_params = 3xdebug.max_nesting_level=200Followed by:
apachectl restart
Here is the summary:
OS: Mac OS Big Sur 11.2.3 PHP: 7.3.24 Xdebug: 3.0.3
I’ve already checked that the zend_extension=location and the compiled module is there
The webserver is loading the correct php.ini There is only one php binary in my system.
There is no Brew setup here. I like to compile and install my own binaries to know what’s going on under the hood.
This is the output of for php -v

Obviously, when trying to use xdebug functions through the webserver they will throw a fatal error since the functions are not defined.

Answer
After banging my head against the wall for a few hours, I was finally able to figure out what the problem was.
There was an error message about xcode not being code signed:
JavaScript
Failed loading /usr/local/php/extensions/xdebug.so: dlopen(/usr/local/php/extensions/xdebug.so, 9): no suitable image found. Did find: /usr/local/php/extensions/xdebug.so: code signature in (/usr/local/php/extensions/xdebug.so) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.I was able to codesign it with my Apple Developer Certificate. However, after that the message changed to:
JavaScript
Failed loading /usr/local/php/extensions/xdebug.so: dlopen(/usr/local/php/extensions/xdebug.so, 9): no suitable image found. Did find: /usr/local/php/extensions/xdebug.so: code signature in (/usr/local/php/extensions/xdebug.so) not valid for use in process using Library Validation: mapping process is a platform binary, but mapped file is notAs it turns out, MacOS 11 requires library validation for everything. My solution, although not recommended if you don’t know what you are doing is to disable library validation systemwide for it be able to load.
You can do it with the following command:
JavaScript
sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool trueThen you can restart apache and the module will load, after that you can reactivate library validation with
JavaScript
sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool falseHappy debugging
