Xdebug 在 CLI 上工作，但 Apache 不會加載它

Question

出於對我生命的熱愛，我無法弄清楚這一點：我已經從源代碼編譯了 xdebug，雖然 CLI 會告訴我它是活動的，但網絡服務器不會。

這是我經歷的過程。

phpize 
./configure --enable-xdebug
make 
make install
mv `compiled module` `desired location` 

然后我編輯了 php.ini 以包括：

zend_extension=/usr/local/php/extensions/xdebug.so
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.mode = develop
xdebug.log_level = 7
xdebug.var_display_max_data = -1
xdebug.cli_color = 1;
xdebug.var_display_max_depth = -1
xdebug.collect_params = 3
xdebug.max_nesting_level=200

其次是： apachectl restart

這是摘要：

操作系統：Mac OS Big Sur 11.2.3 PHP：7.3.24 Xdebug：3.0.3

我已經檢查了 zend_extension=location 和已編譯的模塊是否存在

網絡服務器正在加載正確的 php.ini 我的系統中只有一個 php 二進制文件。

這里沒有 Brew 設置。 我喜歡編譯和安裝我自己的二進制文件以了解幕后發生的事情。

這是 php -v 的 output

這是來自網絡服務器的 phpinfo() 標頭的 output，沒有提及 xdebug。 顯然，當試圖通過網絡服務器使用 xdebug 函數時，它們會拋出一個致命錯誤，因為這些函數沒有定義。

對可能發生的事情有任何想法嗎？

我已經在沒有運氣的情況下查看了大多數其他類似的問題。

Answer 1

在我的頭撞牆幾個小時后，我終於能夠弄清楚問題所在。

有一條關於 xcode 未進行代碼簽名的錯誤消息：

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.

我能夠使用我的 Apple 開發人員證書對其進行代碼簽名。 但是，在那之后，消息變為：

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 not

事實證明，MacOS 11 需要對所有內容進行庫驗證。 我的解決方案雖然不推薦，但如果您不知道自己在做什么，則禁用系統范圍內的庫驗證以使其能夠加載。

您可以使用以下命令執行此操作：

sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true

然后您可以重新啟動 apache 並且模塊將加載，之后您可以重新激活庫驗證

sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool false
