在 RHEL7.8 上编译 php 时，我收到以下警告消息。我可以成功编译和安装 php，但我不确定这些警告会产生什么副作用。有什么方法可以解决这些警告吗？

答案1
您收到这些警告是因为您尝试将 PHP 链接到 OpenSSL 1.1.x ( *.so.1.1)，而 libssh2 链接到 OpenSSL 1.0.x ( *.so.10)。
真正解决这个问题的唯一方法是将 PHP 和 libssh2 链接到同一版本的 OpenSSL（或者您可以尝试弄清楚是否需要引入 libssh2 的组件并避免构建这个 PHP 扩展 - 但这可能是 cURL...因此这个建议可能根本不起作用）。
根据libssh2 的自述文件，您也可以选择自行重建 libssh2，要么完全不支持 OpenSSL，要么支持 libgcrypt。但在执行此操作之前，您应该仔细检查您是否在其他地方使用了 libssh2，以及这种更改会造成哪些影响。
实际上，这个 OpenSSL 链接混合物通常情况下仍然运行良好，即使它会抛出构建时警告……但并不能保证。如果在这种情况下出现问题，除了分段错误或加载 mod_php 或启动 php-fpm 时崩溃之外，我预计它们与加密有关。
