[Dev-C++] linker error

[Schedler, K. <Kur...@hi...>]

I seem to be getting this error a lot when compiling example programs I find
on the web:

c:\my documents\src\cpp\simple\main.o(.text+0x162):main.cpp: undefined
reference to `GetStockObject@4'

Anyone have an idea what is wrong?  This is the offending line of code:

  wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);

And one other thing I wanted to ask about...  when using the menu "wizard"
in the resource editor, I added a "File" item and an "Exit" subitem under
that.  But when the app added the lines of code to my resource file, I ended
up with "File", "File->Exit", and then an "Exit" on the main menu bar as
well.

Oops, one more thing (I promise this will be the last in this message!),
when using Edit->Insert to add an if, while, or for loop template, the curly
braces don't tab over to align with the code above.  Have I not set up
something properly, or am I asking for a new feature?

Thanks,

krs.

[Dev-C++] linker error

[<pi...@we...>]

Hello!
When I try to compile and run a self-written program, there
sometimes appears the following error-message from the compiler/linker:=20
[linker error] undefined reference to 'WinMain@16'
Can somebody explain me the meaning of this message?
Thank you! Andy

[Dev-C++] linker error

[Szathmary L. <sz...@de...>]

Hi,

I'm quite new to Dev-C++, and I ran into a problem. I wanted to compile
this simple prg.:

#include <stdlib.h>
#include <tiffio.h>
#include <tiff.h>

int main(int argc, char *argv[])
{
  TIFF* tif = TIFFOpen("foo.tif", "r");
  // ... do stuff ... 
  TIFFClose(tif);
  system("PAUSE");	
  return 0;
}

but I get the next error: undefined reference to TIFFOpen and to
TIFFClose. In the include directory I have tiff.h, tiffio.h and
tiffvers.h, in the lib dir. I have tiff.lib, and libtiff.a
What is wrong? In the options menu the lib and iclude directories are set
properly.

		Thanks,

			laszlo

It isn't enough that your lib directory contains the tiff libraries. You
also have to add them to the project.

The lib directory is where the linker will look for the libraries.
However, it won't start looking for a library unless the project
references the library.

Open project options, and on compiler options add the needed library.

Hi,

Thanks for the info, I didn't know that. I have two files in lib: tiff.lib
and libtiff.a
I tried to add tiff.lib as "../../DevCpp5/lib/tiff.lib", but when I want
to run it, it says it cannot load libtiff.dll
How can I fix it?

		Thanks,

				Laszlo

When You have a lib*.a, you have to tell to the compiler, You want to use
it. So in the "Project Options" / "Parameters" / "Linker" fill a new
line: -l*

In Your case: -ltiff

[Dev-C++] linker error

[<HH....@TL...>]

I'm using DEV-CC 4.9.8.0 
My questions are:
How can i find out, what "__gxx_personality_v0"  is the alias for? There is
no substring defining a variable or function or something else in that
string. The original message is:
 					[Linker error] undefined reference
to `__gxx_personality_v0'
 I:\Sources\C\PARSER2\Makefile.win	[Build Error]  [DEVPAR.exe] Error 1
Are there sections "compiler-"& "link-messages" within the documentation?
(Unfortunately(?) not found yet!)

[Per W. <pw...@ia...>]

Did you compile as c++?

Make sure that you link with -lstdc++

Re: [Dev-C++] linker error

[Vlada D. <dj...@im...>]

You need to link  winsock library. Go to Project>Project options>Linker =
options and add a line like -lyourlib, where yourlib is the library you =
need to link. For winsock, I think it should be ws2_32 (or maybe =
wsock32).

[Dev-C++] linker error

[Fred J. <ph...@ya...>]

Hello
I have this linker error which makes me think that the
definition file is not being seen by the linker, this
code is taken from "Thinking in C++, 2nd Edition,
Volume 1, Annotated Solutions Guide"
Using Dev-C++ 4.9.9.2, The error is:
[Linker error] undefined reference to ‘f(int)’
all the following files are in the same dir.

thanks

//: S03:Prototypes.h
void f(int);
///:~

//: S03:Prototypes.cpp {O}
// Implements functions declared in Prototypes.h
#include <iostream>
using namespace std;

void f(int i) {
  cout << "f(" << i << ") returning void\n";
}
///:~

//: S03:ProtoTest.cpp
//{L} Prototypes
#include <iostream>
#include "Prototypes.h"

int main() {
  f(1);

  getchar();
  return 0;   
}

[Per W. <pw...@ia...>]

You must make sure that the file Prototypes.cpp (strange file name by the
way since it doesn't contain function prototypes but actual
implementations...) has been added to the project. If not, the compiler
will not compile it (no Prototypes.o generated) and the linker will not
link it.
