Latest version which compiles under linux 64 bit: 2391

[perkins]

For anyone else trying to get this to compile from source on 64 bit linux, revision 2391 compiles with CMake, no issues at all. Revision 2402 does not. If someone gets a later revision to compile, with zero modifications to the code, post the revision number here please.

[Julio Jerez]

what are the errors?

It's not really a big deal. I've never had it just compile right out of the box, but it did for 2391, so I figured that'd be worth mentioning. It might be worth getting a buildbot farm going to produce daily builds for the major platforms.

Here are my build errors:

Oh I am sorry, that was my mistake.
I forgot that I was only setting the precision mode is windows platform, in window some third party libraries has the nasty habit of setting the precision mode to 32 bit floats (d3d is a typical example)
Newton has some unlimited extend precision float class that is use if some of the computational geometry algorithm,
the float are initized from a double and if the precision is set to floats then all of the algorithms fail because the computation algorithm math assume exact arithmetic.
Linux and Mac OS do not seems to do meddle with the float unit, and if they do they restored, but windows developers are more sloppy and do no restore the CUP state.
Engoines Like Ogre and Irrlicth are particularly bad on that, therefore I need to make sure the precision is right.
I recently move that code to a class because I made a mistake very recent working with Boolean, so I decide to make better, but I forget that Linux part.

It is fixed now, you can try again.


It will be nice if I new teh equvalend of _controlfp and _clearfp for GCC, but I do not find it

From revision 2408. Oh, and 2391 and later won't let me link against the library if the package dContainers is disabled in CMakeLists.txt, but it all does compile.

I forge to add the new cpp file to the make file

dgOpenCL.cpp

you can added temporarilly of wait until I add it tonight

Still getting the same error about m_index being undeclared at revision 2412...

[Julio Jerez]

on this:

Still getting the same error about m_index being undeclared at revision 2412...

temporarilly on that function do this

Code: Select all

template<class dgNodeData, class dgEdgeData>
void dgGraphNode<dgNodeData, dgEdgeData>::Trace () const
{
/*
   dgTrace (("%d: ", m_index));
   for (typename dgGraph<dgNodeData, dgEdgeData>::dgListNode* edge = typename dgGraph<dgNodeData, dgEdgeData>::GetFirst(); edge; edge = edge->GetNext()) {   
      typename dgGraph<dgNodeData, dgEdgeData>::dgListNode* const node;
      node = edge->GetInfo().m_node;
      dgTrace (("%d ", node->GetInfo().m_index));
   }
   dgTrace (("\n"));
*/
}
