Root Cause

CGo preprocessor cannot find the header file because include path not specified.

generic

中文

CGo预处理器找不到头文件，因为未指定包含路径。

Workarounds

  1. 90% success Add `// #cgo CFLAGS: -I/path/to/include` 
    // #cgo CFLAGS: -I/usr/local/include
// #include <foo.h>
import "C"
  2. 85% success Use `pkg-config` for automatic include paths 
    // #cgo pkg-config: foo
// #include <foo.h>
import "C"

Dead Ends

Common approaches that don't work:

  1. Copying header to current directory 30% fail

    Works but not scalable; may miss other headers.

  2. Using `-I.` without relative path 50% fail

    Only works if header in current dir.
