Can some one suggest me on this error. "in file included from main.c"?

In you main.c file you have include files (#include ...). This include files also have included files. Thoce included files may also include additional files.





The compiler has found an error while processing those included files.





The most likely reason is that you have included a file that assumes some other include file was already included.





Some times you can fix this by changing the order of the #includes in your main.c. If not you simply have to figure out what piece of information is needed.
