php - linux中编译安装lnmp环境，GD库要单独下载安装吗？

Question

PHP有自带的gd库，但是在编译安装中，需要单独下载gd库安装吗，还是直接用php自带的就可以用，但是网上很多都没有直接用PHP的GD库，而是单独下载GD安装。

Answer 1

Required, --with-gd=path

Answer 2

If you are centos, you need to rely on jpeg and freetype
yum install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel zlib zlib-devel glibc glibc-devel -y
After installing the dependencies
just add the following parameters when configuring
--with-freetype-dir=/usr/lib64
--with-gd
--with-jpeg-dir=/usr/lib64
--with-png-dir=/usr/lib64

Answer 3

If necessary, if you find it troublesome, you can directly install the compiled binary package php-gd.

Answer 4

? ? What comes with PHP is not a library, but an extension. Extensions depend on libraries. Extensions call the functions provided by the library, but do not provide functions themselves. This is also the role of PHP extensions. Therefore, you must install the GD library additionally. The methods of installing the library are generally divided into compile installation and package installation.

Answer 5

apt install xxxxx

Answer 6

Needs to be installed separately, you can compile or choose yum (or apt) to install.
