Go language Makefile Specify the dependent package location

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

The Go program can be compiled with some Makefile scripts to simplify writing Makefile. The official documentation is too brief to mention the need to specify a method that depends on the location of the package. After flipping through the script code, it turns out that ldimports and gcimports can be specified.

Like what:

Include $ (goroot)/src/make.inc  ldimports=-l./pkg/_obj gcimports=-i./pkg/_obj  targ=tool gofiles=\ tool.go\  

GCIMPORTS Specifies the parameters for the compile phase, which are valid for make.cmd,make.pkg. LDIMPORTS Specifies the parameters of the link stage, which is useless for make.pkg.

In addition, you can use similar cleanfiles+= pkg/_obj to clean up more things when make.

And

All:pkg/_obj Tool  

Such a method automatically compiles a dependent package when the dependent package is not compiled.
