Build Golang projects properly with Makefiles

<p><pre><code> BUILD=`git rev-parse HEAD` LDFLAGS=-ldflags &quot;-X main.Version=${VERSION} -X main.Build=${BUILD}&quot; # ... $(BINARY): go build ${LDFLAGS} -o {$BINARY} .&#x2F;.. </code></pre> Please don&#x27;t do that. This ties the build process to be run from inside the git repository, which starts to be a problem if you have any sane method of code deployment (building source packages). Think of something different.<p>And yes, there is a typo in the build rules.

<p><pre><code> ${BINARY}: main.go go build $&lt; -o $@ </code></pre> this way, make will know to re-build the binary only if the source code has changed.
