Problems compiling in Mac OS 10.9 with clang and Qt 4

Hello there,

I am eager to try your samples of the polyvox. I ended up having installed Qt 4.7.4, as Qt 5.4 was not recognised valid for cmake. I read on previous forum post about the use of gcc instead of clang but I have confirmed that make is using clang for CXX.

So here is my compilation errors logs. Do you think you can figure what is the problem? Thank you.

Best,
FB

Hi, I have seen this error before so I know how to fix it. The 0.2.1 (or master) version of PolyVox has this line in AStarPathfinder.h:

Code:

polyvox_function<void (float)> funcProgressCallback = 0

Which gives an error on some more modern compilers. You need to change it to:

Code:

polyvox_function<void (float)> funcProgressCallback = nullptr

There may be other places with a similar problem, but there's certainly not many. This has also been fixed in the latest development version.

Hi there,

thank you. I managed find some more afterwards and to correct it.

Hi there,

didn't manage to finish my post yesterday, but I corrected those 'nullptr' errors and two more, and got some new errors... This time they report to Qt library.

variable has incomplete type 'std::random_access_iterator_tag'
inline bool selectIteration(std::random_access_iterator_tag)

and a warning for mac os x compatibility.

Anyway, I managed to get the samples compiled.

The SmoothLOD crashes with a

I'll be looking into the library and code in more detail. Great work, congrats!

Best,

Obviously we can't fix the Qt errors but the crash is strange. At some point you might want to test the latest 'develop' branch of PolyVox, perhaps some of these issues (at least the PolyVox compile errors) will have been resolved. The library is changing though so you would need to update your code.
