This change is needed because you’re moving from using OpenWRT’s standard Go package infrastructure to a custom implementation. Let me break it down:

Original Line

include $(INCLUDE_DIR)/golang-package.mk

This tries to use OpenWRT’s built-in Go package infrastructure which:

Expects specific file locations

Requires the official golang-package.mk file

Uses predefined build rules that may conflict with your custom setup

New Implementation

$(eval $(call GoPackage))

This instead activates your custom Go package definition that:

Is defined in your golang.mk file

Uses your own build rules and paths

Bypasses OpenWRT’s default Go build system

Why This Fixes Your Error

Avoids Missing File
The error occurred because the build system couldn’t find OpenWRT’s official golang-package.mk. By using your own implementation, you eliminate this dependency.

Custom Build Control
Your golang.mk likely contains a GoPackage macro that implements alternative build steps better suited for your workspace setup.

Path Consistency
Your custom implementation uses paths like .go_work/build that match what you’re actually creating in the build process.

Implementation Notes

Ensure golang.mk contains the GoPackage macro definition

Verify your custom implementation handles:

define GoPackage

Remove any remaining references to OpenWRT’s default Go infrastructure

This change allows full control over the Go build process while maintaining compatibility with OpenWRT’s package framework.
