如何为PHP 7.4及以上版本编译pcntl ?

Question

我正在尝试用以下命令(来自Mac)编译PHP 7.4和PHP 8的pcntl扩展:

wget "https://www.php.net/distributions/php-7.4.0.tar.gz"
tar xvf "php-7.4.0.tar.gz"
cd "php-7.4.0/ext/pcntl/"
phpize
./configure
make

但是，make命令会在每个版本的PHP>7.3中抛出以下错误:

[-Werror,-Wimplicit-function-declaration]
z_rusage = zend_try_array_init(z_rusage);

我如何解决这个错误或获得编译版本的pcntl.so?

Answer 1

下载最新的MAMP版本(包括PHP 7.4.10和PHP 8)

然后改成./configure:

• PHP 7.4。*:./configure --with-php-config=/Applications/MAMP/bin/php/php7.4.12/bin/php-config
• PHP 8。*:--with-php-config=/Applications/MAMP/bin/php/php8.0.0/bin/php-config

之后，我的make命令成功运行并生成了预期的pcntl.so文件。

完整的命令:

wget "https://www.php.net/distributions/php-7.4.0.tar.gz"
tar xvf "php-7.4.0.tar.gz"
cd "php-7.4.0/ext/pcntl/"
phpize
./configure --with-php-config=/Applications/MAMP/bin/php/php7.4.12/bin/php-config
make
