Can't access a function in another file [newbie question]

<p><a href="http://i.imgur.com/FHuGcV4.png">http://i.imgur.com/FHuGcV4.png</a></p> <p>I&#39;m pulling my hair out here... I&#39;m sure I&#39;m doing something wrong.</p> <p>I have a main.go file in one directory, and in another directory adjacent to the main directory, a file that has an exported struct, and a method on that struct (both capitalized). The compiler can see the struct just fine, but for some reason I can not access the method. Screenshot attached for simplicity.</p> <p>What am I doing wrong?</p> <hr/>**评论：**<br/><br/>togamans: <pre><p>the method should be p.SayHello() not lib.SayHello() since it&#39;s a method on the object.</p></pre>potatofloss: <pre><p>Of course! I knew I was being dense. Thanks!</p></pre>gohacker: <pre><p>What IDE/editor is on the screenshot?</p></pre>rpk788: <pre><p>Looks like IntelliJ probably with the Golang plugin:</p> <p><a href="https://github.com/mtoader/go-lang-idea-plugin#how-to-use-it" rel="nofollow">https://github.com/mtoader/go-lang-idea-plugin#how-to-use-it</a></p></pre>
