Thanks for the report.

The Arduino standards used in Visual Micro perform a number of steps to change the INO code to plain CPP code for compilation (merging of INO files, injection of #include Arduino.h, function prototype injection).  The merged file can be seen in the Build Folder (link in the output) with SketchName.cpp.

Within the build folder, there is the .vmpreproc\sketch-gcc-e-clean.cpp which shows the complete pre-processed code (generated using the -E preprocessing option for gcc).

From your errors it seems that either a header or some compilation #defines are missing, if you know where these are supposed to come from we can help in getting these included.
