My program creates .ihx file and other files, when i remove header files from it.

When i include header files it does,nt compile and give error as mentioned before.

Program is nothing but these lines just for test.

This code creates .ihx and other files

prog.c

void main(void)
{
while(1)
{

}
}

But this gives the error as written in my older posts

prog.c

#include <reg51.h>
void main(void)
{
while(1)
{

}
}

I just want to run the program with header files....is some path required to be defined
