尝试在Docker官方映像中将freetype添加到php-gd

Question

我正在尝试向PHP GD安装添加一些功能。我正在使用Docker PHP“官方”发行版作为基础（php：7.1.15-fpm-jessie）。

我当前的生产环境使用CentOS，该GD模块带有FreeType，JPEG和PNG支持，如phpinfo输出所示：

GD Support => enabled
GD headers Version => 2.2.5
GD library Version => 2.2.5
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.4.11
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.5.13
WBMP Support => enabled
XPM Support => enabled
libXpm Version => 30411
XBM Support => enabled
WebP Support => enabled

Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1

但是，此Docker映像不提供FreeType和JPEG支持，并且具有较旧的GD版本（请参见phpinfo，下面）：

GD Support => enabled
GD Version => bundled (2.1.0 compatible)
GIF Read Support => enabled
GIF Create Support => enabled
PNG Support => enabled
libPNG Version => 1.2.50
WBMP Support => enabled
XBM Support => enabled

Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1

我需要重新编译PHP还是仅重新编译扩展名？该图像使用Debian Jessie。

版本（解决方案）：

重新编译后，我在这篇文章中找到了最好的解决方案：

解决了！Docker + PHP7 + GD的问题导致“调用未定义函数imagecreatefromjpeg（）”

所以我简单地添加：

RUN apt-get update && apt-get install libgd3 libgd-dev && rm -rf /var/lib/apt/lists/*
RUN docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/
RUN docker-php-ext-install -j$(nproc) gd

之后，我的phpinfo开始显示：

GD Support => enabled
GD Version => bundled (2.1.0 compatible)
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.5.2
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.2.50

Answer 1

将此添加到您的Dockerfile：

RUN apt-get update && apt-get install -y libpng-dev 
RUN apt-get install -y \
    libwebp-dev \
    libjpeg62-turbo-dev \
    libpng-dev libxpm-dev \
    libfreetype6-dev

RUN docker-php-ext-configure gd \
    --with-gd \
    --with-webp-dir \
    --with-jpeg-dir \
    --with-png-dir \
    --with-zlib-dir \
    --with-xpm-dir \
    --with-freetype-dir \
    --enable-gd-native-ttf

RUN docker-php-ext-install gd

这个对我有用。

Answer 2

对于使用 php7.3 的我来说，如果对我有用，请删除 --enable-gd-native-ttf

RUN apt-get update && apt-get install -y libpng-dev 
RUN apt-get install -y \
    libwebp-dev \
    libjpeg62-turbo-dev \
    libpng-dev libxpm-dev \
    libfreetype6-dev

RUN docker-php-ext-configure gd \
    --with-gd \
    --with-webp-dir \
    --with-jpeg-dir \
    --with-png-dir \
    --with-zlib-dir \
    --with-xpm-dir \
    --with-freetype-dir

RUN docker-php-ext-install gd
