【中文标题】编译 ImageMagick：找不到“libwebp”，从 Amazon Linux 2 上的源代码编译【英文标题】：Compiling ImageMagick: Cannot Find 'libwebp', compiled From Source on Amazon Linux 2 【发布时间】：2021-11-10 20:37:15 【问题描述】：

我正在尝试重新编译 ImageMagick 以启用对 php 的 webp 支持。

问题似乎是当使用./configure --with-webp=yes 编译Imagick 时，它找不到比0.4.1 更高版本的libwebp 库。 Amazon Linux 2 的存储库只能升级到版本 0.3.1。这意味着从源代码编译 libwebp，它可以工作，但 Imagick 似乎无法识别它。

所以我的问题是，如何确保 ImageMagick 可以找到并使用 libwebp 库？

步骤

要从源代码编译，我做了以下操作：

cd /var
sudo wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-1.1.0.tar.gz
sudo tar xvzf libwebp-1.1.0.tar.gz
cd libwebp-1.1.0
sudo ./configure
sudo make && sudo make install

/sbin/ldconfig -p | grep webp 显示以下输出，其中显示 libwebp 库按预期存在于 /usr/local/lib 目录中并在 ld 配置中注册。

   libwebpdemux.so.2 (libc6,x86-64) => /usr/local/lib/libwebpdemux.so.2
   libwebpdemux.so (libc6,x86-64) => /usr/local/lib/libwebpdemux.so
   libwebp.so.7 (libc6,x86-64) => /usr/local/lib/libwebp.so.7
   libwebp.so (libc6,x86-64) => /usr/local/lib/libwebp.so

然后我尝试通过执行以下操作从源代码编译 Imagick：

cd /var
sudo wget https://imagemagick.org/download/ImageMagick.tar.gz
sudo tar xvzf ImageMagick.tar.gz
cd ImageMagick-7.1.0-7
sudo ./configure --with-webp=yes
sudo make && sudo make install
sudo ldconfig /usr/local/lib

但是，当运行 ./configure --with-webp=yes 时，我得到以下输出
