How to resolve mkdtemp error building Go from source in Docker?

<p>I&#39;m trying to compile Go for uClibc in Docker, using the base image xdrum/openwrt:15.05. I managed to work around a bunch of errors about obtaining the source (!) to do with HTTPS, SSL, and git support in OpenWrt.</p> <p>However, the <code>make.bash</code> script presents a strange error that I&#39;m not sure how to resolve.</p> <p>Dockerfile:</p> <pre><code>FROM xdrum/openwrt:15.05 RUN opkg update &amp;&amp; \ opkg install \ gcc \ git \ wget \ unzip \ ca-certificates &amp;&amp; \ wget https://github.com/golang/go/archive/release-branch.go1.4.zip &amp;&amp; \ unzip release-branch.go1.4.zip &amp;&amp; \ sh -c &#34;cd go-release-branch.go1.4/src &amp;&amp; sh make.bash&#34; </code></pre> <p>Trace:</p> <pre><code>$ docker build -t test . # Building C bootstrap tool. cmd/dist go tool dist: mkdtemp(/var/tmp/go-cbuild-SU5ZfI): No such file or directory </code></pre> <p>How can we fix the mkdtemp error in Docker?</p>
