When the file is included for the second time, struct udtCharVec has already been defined, and so you get a "type redefinitio

You can do this in 2 ways. 1) At the top of your header files put: #pragma once Or 2) if your compiler doesn't support that, put at the top/end of your header files: #ifndef _MYFILE_H_ #define http://stackoverflow.com/questions/707920/gcc-compiler-error-redefinition-previously-defined _MYFILE_H_ ... #endif Replace MYFILE with the name of your file, and replace ... with the contents of the header file. share|improve this answer edited Apr 2 '09 at 7:11 unwind 253k38330460 answered Apr 2 '09 at 1:18 Brian R.

This can occur if in cases like: if you define two functions with the same name if there is a mismatch between a function and it's prototype you call a non-trivial function before it has been defined, and without a prototype In this last case there will be a mismatch between the real function and the "implicit declaration" that the compiler assumes whe
