Assume by “run FB5” you mean compile source to an application. See the FBtoC help ( have to open the FBtoC app separately if not already open ) and look at the diagram in the section titled “What is FBtoC?” It shows the difference between the FB4 compiler and the FB5/FBtoC translator. Bottom line: C source MUST be created because all executables are created with the Xcode compilers ( i.e. gcc, clang, llvm etc. ). There is no FB5 compiler as there was in FB4. Brian S
