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 254k38331460 answered Apr 2 '09 at 1:18 Brian R. Bondy 198k82474572 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 Sep 7 '12 at 14:13 add a comment| up vote 9 down vote The error means that there is a symbol that has been defined in one place and an alternate definition has been made in another place. 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

Also, I can provide the source code and headers if needed, but I warn ahead of time... they aren't huge files, but 11 in total including main.cpp. Also, it may be important to note I'm using CMake to build this, but CMake doesn't seem to have issues. Any ideas? Nov 6, 2011 at 11:32pm UTC andywestken (4007) Given the prev definitions are in the same file, it looks like you're including the same headers multiple times. So you need to add guard code 1

I am using Codeblocks (13.12).Here's my "set up":main.c (includes 'int main()')header.h (your error redefinition typical header, includes prototypes)test.c (a random file, includes custom-made functions.)Here's the issue: All the functions works as intended, but when I compile my test.c I get an error (for each function) saying: "error: redefinition of ***"This issue doesn't affect anything, but it's annoying. I'm wondering if it's possible to get rid of it somehow? Maybe I'm doing something wrong when I'm creating my prototypes?Here's an example error redefinition of of what my functions and prototypes look like:Code: [Select]void func_showMenu(); //This is the prototype, in header.h
void func_showMenu(){
//This is the function, in test.c
}Is there some setting in Code::Blocks that can fix this issue?

If each function pair is the same then one complete pair will suffice. Make sure to include the boiler-plate code like the: define that is supposed to be in a header. « Last Edit: December 21, 2015, 07:28:07 pm by headkase » Logged stahta01 Lives here!
