如何为 PHP 7.4 及以上版本编译 pcntl？

如何解决如何为 PHP 7.4 及以上版本编译 pcntl？

我正在尝试使用以下命令（来自 Mac）为 PHP 7.4 和 PHP 8 编译 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 命令在 PHP 7.3 以上的每个版本中都会抛出以下错误：

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

如何解决此错误或获得 pcntl.so 的编译版本？

同样的过程适用于 PHP 4 到 PHP 7.3

解决方法

下载最新的 MAMP 版本（包括 PHP 7.4.10 和 PHP 8）。

然后改变了./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
