Gmagick和GraphicsMagicks：静态链接

Question

我正在尝试编译一本用Go写成的二进制文件，该二进制文件与GraphicsMagick有一个静态链接（GO Gmagick和他的LibgraphicsMagick1-Dev套件）。

实际上，该二进制可以在动态中完美地工作，但是我想开箱即用，以避免安装库，配置等。

我根本不熟悉静态链接，这是我尝试的：

CGO_ENABLED=0
go build --ldflags='-extldflags=-static'

结果是一个错误的雪崩（我将提到一些，输出比那大）：

显然不是创建二进制文件。

好像编译器没有找到要编译的C代码。接下来我可以尝试什么？

我相信问题是，虽然您在静态编译中进行了“ GraphicSmagick”，但libgraphicsmagick.a，您没有静态编译的依赖项，为：

• op_get_max_threads是来自OpenMP
• 来自OpenMP XCLOSEDISPLAY我认为来自Xlib
• 数学功能“ sin”和“ fmod”也来自另一个库
