    <p>Other answer has the simple command to compile this, but here's a very rough and simple Makefile example, to get you started down that road. Create a file named <code>Makefile</code> with these contents, where <code>&lt;tab&gt;</code> must be an actual tab character, not some number of spaces:</p> <pre><code>Craps.exe : Craps.o random.o &lt;tab&gt;g++ -o $@ $^ Craps.o random.o : random.h </code></pre> <p>Then just run</p> <pre><code>make Craps.exe </code></pre> <p>(possibly <code>gmake</code> or <code>mingw32-make</code> instead of plain <code>make</code>).</p> <p>Now Make has some magic built in about file types, so when it sees <code>Craps.exe</code> needs those two <code>.o</code> files, it'll start looking for files it could make them from, and it finds .cpp files, and knows how to compile them into .o files. Now it doesn't implicitly know how make <code>.exe</code> out of <code>.o</code> files, so that's why we have the 2nd line. There <code>$@</code> means the target of the rule (<code>Craps.exe</code> here), while <code>$^</code> means all the files listed after the <code>:</code>.</p> <p>The <code>Craps.o random.o:random.h</code> rule means, that if random.h is changed, Craps.o and random.o needs to be re-created again (these .h file dependencies can be generated automatically, but as long as you have just a few files, writing them by hand is ok).</p> <p>If you need to add more source files, just add them with the .o suffix to the first line, and make will include them in the compilation. Also note how make will only compile changed files... Then you will need to add .h file dependencies when you get more .h files.</p>

    1. COThanks making the makefile helps just as much as the first guy. I had an example in some slides but never got it. Your explanation made me go "Aha! That's how you do it!" So I'm quite happy about you explaining it in such detail.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
