The next hurdle was determining how to proceed after checking out the source files using the following command<pre>make -f client.mk checkout</pre>. I spent a great deal of time at this juncture trying to extract various archives of the newly downloaded source via the Cygwin command prompt in a effort to start the build. I scoured through all the folders looking for an installer or build file. The most worrying part of this excercise was that I could not find my objdir even though I explicitly specified one in my .mozconfig file (i.e. firefox-objdir). Little did I know that I needed to issue a single command to proceed to the next step: <pre>make -f client.mk build</pre> which would initiate the build. Many thanks to [[User:Elichak|Liz Chak]]for providing me with this information. However, in defense of the mozilla build documentation, I must say that it is clearly stated there (in the [http://developer.mozilla.org/en/docs/Build_and_Install#Building Building section]) and I would have seen it had I read the documentation more thoroughlyand perceived that those two are not one and the same.
