Hi Everyone,

I've recently updated to version 10.3.1 of the Xtreme ToolkitPro and I am having problems building our project now.  I'm getting the following errors:


Linking...
ToolkitPro1031vc60SD.lib(deflate.obj) : error LNK2005: _deflateSetHeader already defined in ISLibMSD30.lib(deflate.obj)

LINK : warning LNK4098: defaultlib "LIBCMT" conflicts with use of other libs; use /NODEFAULTLIB:library
Debug/VPExpress.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.


I'm thinking that this may have to do with the inclusion of the PNG support in 10.3?

Has anyone else encountered this?  Or does anyone else know what I should do?

edit: Whoops I forgot to mention that I have been able to compile without any problems using 10.2 and previous versions!

Thanks,

Mark.

Hello, yes in 10.3/10.3.1 we added png support and seems it conflicted with your ISLibMSD30.lib.
 
please open project in IDE and remove in solution explorer GraphicLibrary subfolder, comment #define _XTP_INCLUDE_GRAPHICLIBRARY in Common/XTPVersion.h and rebuild library.

Hi Oleg,

Thanks for the quick reply I will definitely try that and see if I can get it working!  I'll report back with what I find.

Also is there any work around available for us if we wanted to use ISLibMSD30.lib and XXtreme ToolkitPro with PNG support?  Right now PNG support isn't that big of a deal for us but I could see if wanting to implement it in the future.

Perhaps those functions could be wrapped in a namespace or something like that to protect them with conflicting with other libraries?

Thanks again for getting back to me so quickly.

Are you linking the XTP statically?

Hello,
 
I think if totally same version of zlib will be used in toolkitpro and ISLibMSD30 libraries, compiller will not complain. If you can modify ISLibMSD30  library try to copy zlib implementation from toolkitpro to your ISLibMSD30  sources.

And another easy solution -
in GraphicLibrary\zlib\zconf.h in beginning of file add
 
#define Z_PREFIX

Ahh Oleg thanks for the tips, I think that they both will work just fine!

Also, in case you were still wondering we link the Xtreme Toolkit statically.

This doesn't work because the linker says "deflate_copyright" is defined twice.  I have this problem because other libraries I use include "zlib.lib".
 
Why don't you do this:
 
#pragma comment(lib, "zlib.lib")
 
Instead of including the sources explicitely? That would eliminate redundant definitions, and it would ensure that all code uses the same version of the library.

Here's a workaround that worked for me:

Comment out the deflate_copyright declaration in deflate.c for *static* builds. Then put the definition back in for *dll* builds.
