Post subject:  First steps problems: build install
Hi there.
I'm totally new around here, and just more than a noob about C/C++ environment settings.
First of all, let me express my congratulations for the effort you make, by baking and maintaining a so nice engine. Keep up the good work!

And now, comes the pain. :)
I've got the Git sources, installed XCode, QT, CMake, and passed the early stage of "cmake .."
Later, i tried a "make install", and obtained the following errors:


[ 1%] Building CXX object library/PolyVoxCore/CMakeFiles/PolyVoxCoreDynamic.dir/source/ArraySizes.cpp.o
cc1plus: error: unrecognized command line option "-std=c++0x"
make[2]: *** [library/PolyVoxCore/CMakeFiles/PolyVoxCoreDynamic.dir/source/ArraySizes.cpp.o] Error 1
make[1]: *** [library/PolyVoxCore/CMakeFiles/PolyVoxCoreDynamic.dir/all] Error 2
make: *** [all] Error 2


My env is made up this way:

Mac OSX 10.6.8
Qt 4.7.4 (64 bit)
Cmake version 2.8.6
GNU Make 3.81
i686-apple-darwin10-gcc-4.2.1

Please, doctors, tell me if I can save my life! :-)
Thanks in advance, and greetings!

I have very little experience with MacOS X but I see that your version of GCC bundled with XCode is 4.2. This version of GCC is too old to support the C++11 features we use in PolyVox. It seems that newer versions don't have newer versions of GCC and are instead focusing on using LLVM/Clang for C++. Unfortunately Clang's support of C++11 isn't as good as GCC or VS2010. David, perhaps you could check their list of supported features and see it's currently good enough?

The other option is to do what people on VS2005 are doing and replacing the C++11 bits with equivalent Boost functionality. David, I guess you know the current status of this better than I?

Either way, I'm sure we can get it working.

Hi milliams, and thanks for your quick reply.
I Installed the latest possible version of Xcode on Snow Leopard. I'm trying to avoid the Lion upgrade, until it will be more supportive of the whole apps and tools I use normally.
Crossing my fingers. :-)

I also don't have much knowledge of MacOS but here's some pointers:

1) Your version of GCC doesn't appear to support C++0x so you're at least going to have to remove the "-std=c++0x" switch before you get any further. It is specified in the root CMakeList.txt file and possibly in other CMakeLists.txt files as well (there are some in subfolders).

2) You will presumably need to use Boost to provide the missing library features (shared_ptr, function, etc). This is what Visual Studio users do for versions prior to VS2010. Have a look in TypeDefs.h where e.g.'polyvox_shared_ptr' is defined. Add/modify the preprocessor checks so that it uses the Boost versions rather than trying to use the built in versions.

Let us know how you get on...

Sure. I'm going to follow your tips.
Thanks for your help.

Ok, I disabled the advanced c++ stuff, downloaded boost 1.47.0 and placed its dir under polyvox/boost_1_47_0.
After editing the TypeDef.h in order to force boost over gcc, I made a BOOST_ROOT environment variable point to the (complete) above path, and it looks as seen by cmake, which quotes correctly the library version during the dependencies lookup, just after QT.

Now I get a different range of errors. It seems I'm on the good way. :D

Any guess? ;)


EDIT: as I'm trying it on a Mac, should I go for static compilation? If so, how can I force a static build instead of a dynamic one?
Thanks. :)

Post subject:  Re: First steps problems: build install
I don't know exactly what is causing this error. It could be a compiler issue, or it could be there is a subtle difference between boost::function and std::function. At any rate, I suggest we just skip over it by removing the AStarPathfinder for now. Nothing depends on that (except the unit test) so we can come back to it later.

Try commenting out the references to AStarPathfinder in library\PolyVoxCore\CMakeLists.txt

Thanks again for your help. Just followed your tips, and this is the result:

It seems it's still referring to std:: over boost:: or maybe I got wrong. All in all I'm a newbie yet.

It should be fixed if you get latest from Git, or apply this change: https://gitorious.org/polyvox/polyvox/c ... c051868c14
