where is the c2h build report?

I don't have it in front of me but if memory serves me correctly it should be in the Release/Debug folder of your application project. It is xml format so if you have a parser you can display the information any way you like.

There are other generated files in there as well. For example the file with "pre" in the name shows you the source file after the preprocessor has been run which then gets passed to the C2H compiler. People complain about error line numbers being off when using C2H, well if you match them to the preprocessor output file then the line number will match properly.
