解决方案

  1. 85% 成功率 Explicitly link the correct library with full path 
    // #cgo LDFLAGS: -L/usr/local/lib -lfoo
// #include <foo.h>
import "C"
  2. 75% 成功率 Define the missing function in a C source file and compile together 
    Create a .c file next to Go code, then `go build` will compile it.

无效尝试

常见但无效的做法:

  1. Adding `// #cgo LDFLAGS: -lfoo` without verifying library path 60% 失败

    Library may be in non-standard location or misspelled.

  2. Reordering C code in the same file 90% 失败

    Does not resolve missing external symbol.
