[Dev-C++] Link Error: variable 'vtable for Gtk::TreeViewColumn' can't be auto-imported

[Marcelo D. <mds...@ya...>]

In Linux the link is ok, but in Dev-C++ (Windows) I
have the error:
 
cp.cpp: variable 'vtable for Gtk::TreeViewColumn'
can't be auto-imported. Please read the documentation
for ld's --enable-auto-import for details.

This error ocorr to with the example of Gtkmm Tutorial
book: 

http://www.gtkmm.org/docs/gtkmm-2.4/examples/book/treeview/list/


I'm using Dev-C++ 4.9.9.2_setup.exe,
gtkmm-devel-2.6.2-1.exe,
gtk-win32-devel-2.6.8-rc1.exe.

I configured the Project Options for Compiler and
Linker using pkg-config --cflags gtkmm-2.4, and --libs
gtkmm-2.4.

I dont know where is the documentation indicated in
the message error.

thank's
(o_o) - mds

[Dev-C++] Undefined Reference?

[Scott <fre...@ve...>]

Hi, 

I'm getting 18 errors like the following with DevC++

I use DevC/C++ without problem usually, but i get
these errors, as part of a 3D SDK....

Is it a Opensource OGL library issue, can it be fixed?

  [Linker error] undefined reference to `glClearColor@16' 
  [Linker error] undefined reference to `glClear@4' 
  [Linker error] undefined reference to `glColor3f@12' 

Cheers,
Scott.

[Hind F. <the...@ho...>]

Did you add the library in the linker (see project options)?
Do it and u will fix the problem.

Thanks Hind, I found the option you mean..
Project Options >>> Parameters>>>> Linker Options

I click "add library or object" i then chose libglut
and another libglut32.a which removed the 18 errors..
And replaced it with just 1 error... (Doh!)

"Cannot find -lobjc"    is now the error.... Any ideas?

Thanks again for any help!


Cheers,
Scott.

Hi Scott, 
 
Try doing a Windows Explorer Search from F:\Programming\Dev-Cpp\ for libobjc*.*.  It should reside in the lib folder of dev-cpp or in a path declared in the libraries directory of the project options.  dev-cpp only searches default paths and paths defined by the user.
 
You may find that it's not in the expected path.  That assumes that the argument to the linker options is -lobjc, BTW.

Hi Alfred,=20

Hmm i can't seem to find it at all, in my DevC++ install.
I did a search i found 12 files with a "libo*.*   prefix

But alas, did not find any matching or looking like libobjc.
in any directories, anywhere  (strange) Anything else i can do?

Can someone send me this file?
I will look at doing a Reinstall after that...

Thanks again...

Cheers,
Scott.
