Does my AS3 project need a preloader?
===

I'm just starting to develop an AS3/MXML application on Linux using the command-line Flex 4 compiler. When running `mxmlc -source-path=. MyApp/Main.as`, I get the following warning:


    /home/andreas/projects/as3/MyApp/src/MyApp/Main.as: Warning: This compilation unit did not have a factoryClass specified in Frame metadata to load the configured runtime shared libraries. To compile without runtime shared libraries either set the -static-link-runtime-shared-libraries option to true or remove the -runtime-shared-libraries option.

Another [SO answer](http://stackoverflow.com/questions/3079112/compiling-with-flex4-sdk) says that the solution is to link to my preloader. I don't think my project needs a preloader as it's pretty small; can I just ignore the warning?
