Porting from CSS Ti compiler to GCC (Newb)

gmake: *** [main.o] Error 1

gmake: Target `all' not remade because of errors.

 

How do I fix that?

 

NOTE/CLUE:  I tried making a new, blank GNU_4.6.3:MSPGCC project in CCS, and it gets identical compile errors.  However, a new "Energia Sketch" does not have this problem.  What is the difference between an "Energia Sketch" and a regular project?  If the end-functionality is identical, I can just switch project types, but I don't know if a sketch project has any "gotcha"s that I will regret later.

 

 

In case anything else is useful, here is the full console output of a failed compile:
