I am new to developing for Firefox and am having difficulty getting the source code to compile. I have been following [this guide](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Simple_Firefox_build) as best I can, but when I go to build it, I get the following set of errors: <code> 54:03.62 IOError: [Errno 2] No such file or directory: u'c:\\mozilla-source-2\\cse403-finalprog\\mozilla-central\\other-licenses\\nsis\\Plugins\\AccessControl.dll'<br /> 54:03.62 c:/mozilla-source-2/cse403-finalprog/mozilla-central/toolkit/mozapps/installer/windows/nsis/makensis.mk:104: recipe for target 'webapp_uninstaller' failed<br /> 54:03.62 mozmake.EXE[6]: *** [webapp_uninstaller] Error 1<br /> 54:03.62 Makefile:39: recipe for target 'libs' failed<br /> 54:03.62 mozmake.EXE[5]: *** [libs] Error 2<br /> 54:03.62 c:/mozilla-source-2/cse403-finalprog/mozilla-central/config/recurse.mk:79: recipe for target 'webapprt/win/libs' failed<br /> 54:03.62 mozmake.EXE[4]: *** [webapprt/win/libs] Error 2<br /> 54:03.63 c:/mozilla-source-2/cse403-finalprog/mozilla-central/config/recurse.mk:32: recipe for target 'libs' failed<br /> 54:03.63 mozmake.EXE[3]: *** [libs] Error 2<br /> 54:03.63 c:/mozilla-source-2/cse403-finalprog/mozilla-central/config/rules.mk:557: recipe for target 'default' failed<br /> 54:03.63 mozmake.EXE[2]: *** [default] Error 2<br /> 54:03.63 c:/mozilla-source-2/cse403-finalprog/mozilla-central/client.mk:419: recipe for target 'realbuild' failed<br /> 54:03.63 mozmake.EXE[1]: *** [realbuild] Error 2<br /> 54:03.63 client.mk:181: recipe for target 'build' failed<br /> 54:03.63 mozmake.EXE: *** [build] Error 2<br /> 54:03.68 17 compiler warnings present. </code> I'm using Visual Studio 2015, but I've tried it with 2013 as well. Any assistance you can give me would be greatly appreciated.
