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

Is this something with compiler(clang!?) version? It works fine with php 7.2. But for php 7.3 and 7.4. the same error happens.

Answer 1

Installation of the command line tools for Xcode 12 worked for me. It updates Clang to 12 version.

Another trick is to disable asm goto operators by setting # define ZEND_USE_ASM_ARITHMETIC 0 in /usr/local/Cellar/php/7.4.11/include/php/Zend/zend_operators.h:508

Answer 2

The disable asm goto operators trick worked for me, I'm using PHP 7.4.12 by the way. I had to change the first line below from 1 to 0:

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

Answer 3

You can try to install the command line tool for XCode 12, here.
