How is a Go release package created from the source?

<hr/>**评论：**<br/><br/>farslan: <pre><p>If you mean the binaries and packages under /dl check this out: <a href="https://github.com/golang/build/tree/master/cmd/release" rel="nofollow">https://github.com/golang/build/tree/master/cmd/release</a> You see that it uses <code>pkgbuild</code> for creating the darwin installer for example. It&#39;s fairly easy if you follow it (I&#39;ve created a more extensive pkg installer once based on this).</p></pre>lapingvino: <pre><p>Ah great :) the point mostly being that I managed to build go 1.5 with itself with the packaged release, but not with the one built from source... What am I missing there?</p></pre>DeedleFake: <pre><p>Do you mean that you set GOROOT_BOOTSTRAP to the root of the source tree you just built and then tried to rebuild it? That won&#39;t work; the tool binaries get deleted as part of the build process, making it kind of difficult for the bootstrap process to call them.</p></pre>lapingvino: <pre><p>so for the bootstrap, where and which tools should be there?</p></pre>DeedleFake: <pre><p>You&#39;ll need a seperate, existing, precompiled Go toolchain. You can get a precompiled toolchain from the <a href="http://www.golang.org/dl" rel="nofollow">Go download page</a>. Put it somewhere temporary, and then set <code>GOROOT_BOOTSTRAP</code> to it&#39;s path when you run <code>all.bash</code>. Once that&#39;s done, you can use the newly compiled toolchain instead, although a toolchain can&#39;t be used to compile itself. If you want to for some reason, you can just copy the <code>src</code>, <code>pkg</code>, and <code>bin</code> directories into a second directory, and then set <code>GOROOT_BOOTSTRAP</code> to that directory&#39;s path.</p></pre>: <pre><p>[deleted]</p></pre>pierrrre: <pre><p><a href="http://golang.org/dl/" rel="nofollow">http://golang.org/dl/</a> ?</p></pre>
