Missing header files

[buggs]

How come there are times when I get many errors related to header files that are in the program but the compiler will return with undefined printf(); or undeclared variables that are declared??<br>

I dont know what your particular situation is, but sometimes people write programs with multiple source files and only #include the header files in one or a few of the source files. Now you update a source file that has a reference to one of the functions in that header file and Build, it doesnt read the header file because none of the files that contain the #include for that header file are being recompiled.<br>

I think you should be more specific about your problem . But yes if your program consists of more than 1 source files , then you should be cautious about extern usage. And Conditional compilation. like usage of #define so that only once the file is included. <br><br>Does that answer your question ?<br>Thanx<br>Siddhartha Singh<br><A HREF="mailto:ssingh@aztecsoft.com">ssingh@aztecsoft.com</A><br>
