With Win 7, VC++2010, in debug mode,I built PolyVox from sources. every thing goes ok including build and link process. When I run the basic example.exe file, following error accurs:

How to solve it? please help.

If you set a break point at the start of your main() funtion in 'examples/basic/main.cpp' does it hit it? I'm assuming that it doesn't, that it crashes before it even gets this far.

I think this error is usually caused by missing .dll files. The basic example is dependant on both PolyVox and Qt so it will need to be able to find these dlls at runtime. Are the Qt dlls in your system path? You could try copying the Qt dlls into the same solder as the executable. Make sure the PolyVox dlls are in there as well. And what if you run the executable from explorer rather than VS2010?

If you still have problems, you might want to check out Depenancy Walker to identify which dlls are missing. You can post the results here if you can't make sense of them.

Below seems to be the problem:

Why does those dlls missing?

After finding these dlls, here are still problems:

I totally confused. when I run the same .exe in my another laptop which is windows XP OS, It works fine. But in the OS of Win7, the problem can not be solved.

the texts below seems to be the vital problems:

How to solve?

I can't write much because i'm at work, but it looks like the problem is with Qt. Also, I *think* that msvcp90d.dll is from an earlier version of visual studio? Did you used to have VS2008 installed, and maybe you used it to build Qt?

yes, I used to have VS2008 installed and build Qt, then I have my OS updated to Win7 and installed the VS2010. How to solve it without rebuild or reinstall the Qt?

Ok, I'm not an expert on VS2010/VS2008 and compatibility issues but I'll give my ideas. Have you written other software with Qt before? If so it would be worth trying to compile your existing software with VS2010 in order to test whether that really is the problem.

If the problem is compatibility with VS2010, and if you intend to use VS2010 for most of your development in the future, then I guess it makes sense just to rebuild Qt for your new compiler.

On the other hand, if you still like to use VS2008 for some existing projects then this might not be a good idea. An alternative it to try building PolyVox and the examples with VS2008 instead. The only problem with this is that VS2008 does not provide the 'shared_ptr' class, and so you will need to install part of Boost in order to get this. The Boost installer will let you pick just the part that you need as getting the whole thing is massive.

When you run CMake on PolyVox you can tell it which compiler to use. I *think* the command will be:



I should warn you that I don't really test with VS2008 so I can't be certain it will work. You will also need a recent version of PolyVox as I only added the VS2008 support a couple of weeks ago.

Thank you very much, David. It seems that to recompile Qt in VS2010 may comsume a lot of time and a little bit complicated. As for Qt is not my point, I finally decided to only focus on the PolyVox part and omit Qt part. Thank you your generous answer.

Yes, that is also possible of course as Qt is only used for the examples. But do let me know if you have any more questions.
