[Dev-C++] HELP !!

[Felix A. <an...@cb...>]

Hi all, 

 

I'm a novice in C++ and I'm trying to use GNU cgicc library. I've a
problem like this :

 

I've installed the cgicc library in my include directory file, I assure
you that I can call the header file from my source code eg. #include
"cgicc/HTTPHTMLHeader.h"

But the error message like the below keep popping up.

 

C:\DOCUME~1\Felix\LOCALS~1\Temp\ccIpbaaa.o(.text+0x32)     [Warning] In
function `main':

[Linker error] undefined reference to
`cgicc::HTTPHTMLHeader::HTTPHTMLHeader()' 

[Linker error] undefined reference to
`_imp___ZN5cgicclsERSoRKNS_11MStreamableE' 

[Linker error] undefined reference to
`cgicc::HTTPHTMLHeader::~HTTPHTMLHeader()' 

[Linker error] undefined reference to
`cgicc::HTTPHTMLHeader::~HTTPHTMLHeader()' 

[Linker error] undefined reference to `_GLOBAL__I_main' 

[Linker error] undefined reference to `_GLOBAL__D_main'

 

my code is :

 

#include <iostream>

#include "cgicc/HTTPHTMLHeader.h"

 

using namespace std;

using namespace cgicc;

 

main()

{

 

cout << HTTPHTMLHeader() << endl << endl ;

cout << "Hello world" ;

return (0);

}

 

it should be right and return "Hello world" right ???

 

This is very confusing. I don't understand what does  : undefined
reference means. I use Dev C++ 4.9.8.5 on WinXP

 

Anyone can help ? Thank you very much

 

Sincerely

Felix Ang
