Hi. I get these compilation errors on Windows 7 x64.
I had to do this because by default it was compiling in debug mode...
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=release ..
Then I executed nmake and the compilation went up to 81% and this is where I got these errors. What library am I missing here? Thanks for your help.

probably not related, but I think you need to use ming32-make when using the MinGW generated makefiles. this is shown in the Install.txt

I have never tried building with graphviz on windows. did you also build graphviz yourself and with the MinGW compiler system?

[krf]

@programmernoob: You're missing the gvc and (cgraph or graph) library. Both should be in your Graphviz install directory. I'm wondering why CMake doesn't bail out on configure time. Do you actually intend to build the State Machine plugin? If yes, can you show us the arguments you pass to CMake and attach/pastebin the contents of CMakeCache.txt?

[programmernoob]

I used the Nmake and not the ming32.
No I didn't build graphviz myself. But I did build Cmake and VTK myself.
I've got these files : cgraph.dll, graph.lib, graph.h
Is that what you're talking about?
I also seem to have gvc.dll, gvc.lib, gvc.h, gvcext.h, gvcjob.h, gvccommon.h files.
Does this mean that I have the gvc installed but cmake is unable to find it? Do I have to set a system environment variable for gvc and (cgraph or graph) ?

I've got no clue what the State Machine plugin actually is. Do I really need it? This is my first time wanting to try GammaRay. Thanks for the help.

Here is my CMakeCache.txt file:
http://paste.ubuntu.com/7133751/

[krf]

@programmernoob: I suggest trying to build that without Graphviz support for now. Clear CMakeCache.txt and don't explicitely pass GRAPHVIZ_ROOT.

We have to apply some more fixes to actually be able to use that third-party library on Windows.

The State Machine plugin is for live-debugging QStateMachine instances, you can learn more at: https://www.kdab.com/kdab-products/gammaray/

[winterz]

I noticed that the Graphviz Windows installer only provides the 32-bit version. So I expect the FindGraphviz will succeed, but the linking will fail when attempting to build a 64-bit version.

I haven't found a 64-bit Graphviz installer yet.

[krf]

I think we can close this. You'd have to manually compile Graphviz in order to be able to actually link against it.
