Go CGO usage, novice easy to meet the third party C language Library of the library file or header file is not found in the case

This is a created article in which the information may have evolved or changed.

The situation I met was

Under the Windows platform MinGW compiled using a third-party C-language library, I need to set environment variables for MinGW to indicate that MinGW's gcc command compiles when looking for header files and library file directories

And CGO doesn't seem to care or deny the environment variables I set for MinGW

Need to set the address of the header file and library file yourself

such as the use of CGO parameters

#cgo CFLAGS:-I.. /.. /cinclude

#cgo ldflags:-L. /.. /clib-lgsasl

#include <gsasl.h>

......

CFLAGS

The top indicates the header file address

Ldflags

The bottom indicates the library file address

is the relative position of the current file

-I (Uppercase) indicates the header file directory

-L indicates that the library file directory-l (l lowercase) indicates that a specific library file is used

Thank you for this piece of paper that reminds me.
