make: *** [php_memcached.lo] Error 1
ERROR: `make' failed

这是编译器（clang！？）版本的东西吗？ 它适用于 php 7.2。 但是对于 php 7.3 和 7.4。 发生同样的错误。

Answer 1

为 Xcode 12 安装命令行工具对我有用。 它将 Clang 更新到 12 版本。

另一个技巧是通过在/usr/local/Cellar/php/7.4.11/include/php/Zend/zend_operators.h:508设置# define ZEND_USE_ASM_ARITHMETIC 0来禁用 asm goto 操作符

Answer 2

禁用 asm goto 操作符技巧对我有用，顺便说一下，我使用的是 PHP 7.4.12。 我不得不将下面的第一行从 1 更改为 0：

# define ZEND_USE_ASM_ARITHMETIC 0 
#else
# define ZEND_USE_ASM_ARITHMETIC 0
#endif

Answer 3

您可以尝试在此处安装适用于 XCode 12 的命令行工具。
