Error Redefinition Of ‘class

takes a minute: Sign up GCC compiler error: “redefinition…previously defined” up vote 7 down vote favorite 3 I'm getting a lot of " redefinition of x....x previously defined here". Please what does this error means? c++ gcc compiler-construction share|improve this question asked Apr 2 '09 at 1:00 caesar add a comment| 3 Answers 3 active oldest votes up vote 20 error redefinition of c++ down vote You need to limit each file from being included only once. 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 _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 254k38330460 answered Apr 2 '09 at 1:18 Brian R. Bondy 197k82473571 1 I think that #pragma only works in VC++, not in gcc. The #define trick is portable. –Gorpik Apr 2 '09 at 7:19 supoprted by gcc and vc++ –Brian R. Bondy Apr 2 '09 at 10:29 Wikipedia says #pragma once is supported by VC++ and gcc en.wikipedia.org/wiki/Pragma_once . –Max Lybbert Apr 3 '09 at 20:48 #pragma works fine with gcc.. I'm using it at this very moment after I reading about it and it solved a ton of errors! –mmoment

If I include http://stackoverflow.com/questions/5430019/redefinition-errors-in-h-files those header files in smatrix.h file then I get redefinition of 'lnode'. redefinition of '_llist' and redefinition of '_matrix' errors. If I took those heder files our from smatrix.h file then the error went away but it complains about matrix type in the function parameter. I want to call functions defined in list.h and matrix.h files in smatrix.c file.. What do I do?

Try to guard your header files with file list.h #ifndef _LISTH_ #define _LISTH_ #endif file matrix.h #ifndef _MATRIXH_ #define _MATRIXH_ #endif It will prevent you too have redefinitions if you have a loop in header inclusions. share|improve this answer edited Mar 25 '11 at 8:29 answered Mar 25 '11 at 8:21 M'vy 3,96011532 list.h like this? –LCYSoft Mar 25 '11 at 8:27 @LCYSoft Edited –M'vy Mar 25 '11 at 8:29 Thanks a loooot! –LCYSoft Mar 25 '11 at 8:42 You welcome @LCYSoft –M'vy Mar 25 '11 at 8:46

This is because main.cpp line 1 - includes interger.cpp which itself includes object.cpp. and on line 2 there is include object.cpp So object cpp gets included twice which means that class Object is seen twice by the compiler - hence the error. The way you are including cpp files is not the recommended way of doing things. Class declarations are usually put into header files. The code for the class is put into the cpp file. The header file should have a header guard to prevent multiple inclusion errors. Example of header guard object.h 1
