Always start with the first compiler error. Often, the rest are after-effects.
Missing definitions usually caused by incorrect or missing includes.
Either you forgot one or more important include files, or this includes require you to state certain preprocessor defines.
Check you includes and include paths.
If they are fine, check for # ifdef / # elif / # endif sections in the header file containing the "missing" definitions.
Or consult the TouchGfx tutorial.
