When writing ...Good all rounder, except one thing.<br /><br />When writing C++, you need to have everything inside a class or a function. I was writing a C program and got LNK2005 and I couldn't understand the problem. The thing was VS was compiling the code as C++, which doesn't allow variable definitions in .h files.<br /><br />Project propertise -> configuration properties -> C/C++ -> Advanced -> Compile As to Compile as C Code fixed my problem. That or encasing the variable in a class aka. actually write C++ code =PUnknownhttps://www.blogger.com/profile/01655062343078248654noreply@blogger.comtag:blogger.com,1999:blog-8742720.post-22754134624267027852010-03-12T12:38:52.662-05:002010-03-12T12:38:52.662-05:00I'm still struggling with this problem!

I've tried the advice given but I did notice when this error occurs for me.<br /><br />For example, say I have program.cpp and program.h and a use_program.cpp<br /><br />use_program.cpp has a: include "program.h" and program.h has a: include "tools.h"<br /><br />tools.h is composed of function definitions, so there is no separations of function body and header. Every function in tools.h will have the LNK 2005 error. When I separate tools.h into a .cpp and .h file, then the functions work fine. <br /><br />I tried another test where I have a: include "something.h" that works perfectly fine (only has struct definitions) and included a single function definition in something.h. Before, my program was compiling fine (I left out the include tools.h) and with the new function addition, that is the only function that gets the error... help anyone?britthttps://www.blogger.com/profile/06544827757315727458noreply@blogger.comtag:blogger.com,1999:blog-8742720.post-15189922695415741442010-02-07T16:07:18.389-05:002010-02-07T16:07:18.389-05:00Thanks Thomas!!

The above suggestions...I ran into a LNK2005 today. The above suggestions are good and valid. But I might offer one more: the LNK2005 I had today was due to some C++ code from a vendor library that failed to use the static keyword on a declaration within a header file that is intended to be a global.<BR/><BR/>e.g.<BR/>Some_type some_global_data(1,2,3); // defined outside a class body, etc.<BR/><BR/>Adding the "static" keyword before this declaration fixed my LNK2005 problem. And, my apologies if this was actually already suggested and I just missed it.voidstarhttps://www.blogger.com/profile/03808597194361824932noreply@blogger.comtag:blogger.com,1999:blog-8742720.post-47620365603092760572008-05-15T01:05:00.000-04:002008-05-15T01:05:00.000-04:00Hey, I just want to say thanks for this post, you ...Hey, I just want to say thanks for this post, you helped me out tremendously!<BR/><BR/>Option #2 was the one that fixed it for me.<BR/><BR/>Thanks again!Chrishttps://www.blogger.com/profile/07847816113512028351noreply@blogger.comtag:blogger.com,1999:blog-8742720.post-16166028297021769282008-03-06T09:07:00.000-05:002008-03-06T09:07:00.000-05:00allrounder - Excellent!
