问题描述

在 Linux 下编译 PHP 7.4.9 源码，运行以下命令。

$ ./configure --prefix=/opt/php-7.4.9 --enable-fpm --with-pdo-mysql --with-zip --with-curl --enable-mbstring

最后报错了。

configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables LIBXML_CFLAGS
and LIBXML_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.
See `config.log' for more details
