Choosing which compiler to use
From OHRRPGCE-Wiki
FreeBasic is the only compiler which can compile the current OHRRPGCE source. QuickBasic can be used to compile old (hasta-la-qb or earlier) QB-supporting releases.
[edit] FreeBasic
FreeBasic is what you should be using. Only OHR versions since Serendipity can be compiled with it. You must use version 0.15b. 0.16b is not supported yet.
[edit] QuickBasic 4.5
For most of its development, the OHRRPGCE has been compiled with QuickBasic 4.5. If you are working with older versions, you may need this.
[edit] QuickBasic 7.1
QuickBasic 4.5 versions of the OHRRPGCE also have limited support for QuickBasic 7.1 PDS. However, due to some problems, this is not recommended unless you are unable to run QB45 on your computer for some reason.
[edit] Other Languages
If you want to be working in other languages, such as Python or C++ you should read about OHRRPGCE Source Ports
