FW: [Dev-C++] Problems with MySQL (also with GTK)

[J M. <jm...@we...>]

Hi All,

I've got a similar problem with GTK.

What does 'add ... to your project' mean.

I thought all I had to do was make a reference
to the directory that contained the *.a files in the
Tools: Compiler Options: Directories: Libraries dialog.

Although I've got lots of references in the Libraries box the
compiler still doesn't seem to be finding the libraries for GTK.

I'm using Dev-C++ 4.9.2.0 (beta 5) on a Windows 2000 box.

These are the errors I'm getting:
Line  Unit                               Message
10    //F/Dev-C++/Projects/GTK/main.cpp  undefined reference to
'gtk_init_abi_check'
12    //F/Dev-C++/Projects/GTK/main.cpp  undefined reference to
'gtk_window_new'
13    //F/Dev-C++/Projects/GTK/main.cpp  undefined reference to
'gtk_widget_show'
15    //F/Dev-C++/Projects/GTK/main.cpp  undefined reference to
'gtk_main'

You must add libmysql.a to your project. You can find it at:

I have experienced similar problems and am now confused (which is not
difficult!).

As I understand it, if you include the relevant header (*.h) files in your
code and then include the directory which contains the corresponding *.a
file (or lib file) in your libraries search path, then the linker will
search libraries on that path to resolve the reference.

To state it clearly, you are saying I have to link with that particular
library, rather than just include the search path?

GCC does not know by it'self, what .a file contains required code. So
you must specify those libs by yourself. Only reference to dir
containing libs is not good enough.

For example: if you compile standard c++ code (iostream etc.) it woulnt
compile without -lstdc++ lib. (or atleast I have experienced so)

You will have to link to the GTK+ libraries.
Add these to your Linker options:
-lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgdk_pixbuf-2.0 
-lpangowin32-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 
-lintl -liconv -limm32 -lshell32 -lole32 -luuid -lgdi32 -lm


The next version of my GTK+ package will include a template that does 
that automatically for you.
