GO | create 2 different executables on the same module

Question

I would like to know if it is possible to create 2 different executables on the same module, main1.go -> main1.exe main2.go -> main2.exe

root
    -> main2.go
    -> main1.go

the goal is to run Makefile, which will create 2 different executables. Thanks

LATE_TARGET_HOOK=make_main
LATE_TARGET_HOOK=make_client
DS_CONF = ds.conf

export GOROOT := $(UV_golang_PKG)
export GOPROXY := http://****-product.****.com:****/artifactory/api/go/go
export GOSUMDB := off

export PATH := $(PATH):$(GOROOT)/bin
export VERSION := $(shell (cat $(SRCROOT)/VERSION))
GO =$(GOROOT)/bin/go

CONF_FILES = VERSION

include $(MODULEMK)

ifndef UV_BUILDNUMBER
    UV_BUILDNUMBER = 0000
endif

make_main:
    ${GO} mod tidy
    GOARCH=amd64 GOOS=linux CGO_CFLAGS=$(CGO_CFLAGS) CGO_LDFLAGS=$(CGO_LDFLAGS) $(GO) build $(BUILD_FLAGS) -o $(SRCROOT)/CMpub/bin/$(UV_O)/agentExporters .

make_client:
    ${GO} mod tidy
    GOARCH=amd64 GOOS=linux CGO_CFLAGS=$(CGO_CFLAGS) CGO_LDFLAGS=$(CGO_LDFLAGS) $(GO) build $(BUILD_FLAGS) -o $(SRCROOT)/CMpub/bin/$(UV_O)/disableCollector .

Yes this is possible but not with your go build commands. Refactor. — Volker, Feb 01 '23 at 15:58
A module can produce two executables, but a single package cannot. Create a package for each executable. — Charlie Tumahai, Feb 01 '23 at 16:31

but a single package cannot. Create a package for each executable.

How it is can be done?

By using different cmd packages inside your project, as I mentioned before.

This is described in details with "Packing multiple binaries in a Golang package " in 2018, by Ilija Eftimov

› tree
.
└── cmd
    ├── cookie
    │   └── main.go
    └── eight_ball
        └── main.go

A go install ./... would find those main packages and compile/install them separately.

A more modern/different approach would be with "Getting started with multi-module workspaces": you could work on different modules (one per command) within the same workspace.

With multi-module workspaces, you can tell the Go command that you’re writing code in multiple modules at the same time and easily build and run code in those modules.
