# v1.12  NNSC:github.com/hlandau/degoutils/_stdenv/Makefile.ref
# This is a standard Makefile for building Go code designed to be copied into
# other projects. Code below this line is not intended to be modified.
#
# NOTE: Use of this Makefile is not mandatory. People familiar with the use
# of the "go" command who have a GOPATH setup can use go get/go install.

# XXX: prebuild-checks needs bash, fix this at some point
SHELL := $(shell which bash)

## Paths
ifeq ($(GOPATH),)
# for some reason export is necessary for FreeBSD's gmake
export GOPATH := $(shell pwd)
endif
ifeq ($(GOBIN),)
export GOBIN := $(GOPATH)/bin
endif
ifeq ($(PREFIX),)
export PREFIX := /usr/local
endif

## Quieting

## Buildinfo

prebuild-checks:

		if [ -e "$(GOPATH)/src/$(PROJNAME)/" ]; then \
			echo "$$GOPATH/src/$(PROJNAME)/ already exists, can't auto-relocate. Since you appear to have a GOPATH configured, just use go get -u '$(PROJNAME)/...; go install $(BINARIES)'. Alternatively, move this Makefile to either GOPATH or an empty directory outside GOPATH (preferred) and run it. Or delete '$$GOPATH/src/$(PROJNAME)/'."; \
			exit 1; \
		fi; \
		mkdir -p "$(GOPATH)/src/$(PROJNAME)/"; \
		for x in ./* ./.*; do \
			[ "$$x" == "./src" ] && continue; \
