[help] Compiling on mac OSX - Ogre Addon Forums

I've been trying to compile on OSX. This is using the CVS version.

I've managed to get the mapsplitter to work, and now I'm working on the plugin.

I had to change a bunch of the #includes from "ogre.h" to <Ogre/ogre.h> (and all the ones like that), but now I'm running into a few more errors.

1:

OgrePagingLandScapeIntersectionSceneQuery.cpp:51: error: 'class Ogre::PagingLandScapeSceneManager' has no member named 'getEntities'

When I look at PagingLandScapeSceneManager, getEntities() is commented out. Is there a reason it's commented out? Can I uncomment it?

2:

OgrePagingLandScapeIntersectionSceneQuery.cpp:63: error: 'class Ogre::PagingLandScapePageManager' has no member named 'getPagingLandScapeRenderOpsInBox'

Once again, the error is correct.... there is no getPagingLandScapeRenderOpsInBox.

Any ideas?
I'm sure I'll get some more errors after I get passed these, but I would love to get this working on my mac!

"ogre.h" to <Ogre/ogre.h> : are you sure you can't change the compiler include path to Ogre instead ?

I have no getEntities nor getPagingLandScapeRenderOpsInBox calls in OgrePagingLandScapeIntersectionSceneQuery.cpp here. Double check you have latest cvs version.

Are you using Ogre CVS HEAD ? (required to compile cvs plsm2)

3dmacuser2

13-10-2005 20:35:55

Ah, I'm using Ogre 1.0.5 and I got pgsm2 from cvs on the 9th.

I'll upgrade to HEAD and update pgsm2 from cvs.

And yeah, changing the compiler include path would probably be quicker

I'll do that next time.

Thanks!

Ogre CVS HEAD is harder to compile (freetype and cegui version dependency changed and you must compile them on your own too.)

Perhaps you should try to compile against Ogre SDK using plsm2 SDK compatible source to save you some difficulties. (here)

3dmacuser2

13-10-2005 21:09:00

Is there a mac decompresser for .7z ? If not, would you mind sending me a copy of that in .zip or .tar.gz ?

You're right, I'm getting tons of linker errors compiling CVS HEAD.

Nevermind, found one. I'm going to try it out now.

Thanks for your help!

does this one work http://homepage.mac.com/krmathis/ ?

I got a 7z unarchiver at http://emulation.victoly.com/download/

Ok, so using the source in that file, I'm still getting errors:

In OgrePagingLandScapeIntersectionSceneQuery.cpp:

OgrePagingLandScapeIntersectionSceneQuery.cpp:51: error: 'class Ogre::PagingLandScapeSceneManager' has no member named 'getEntities'



OgrePagingLandScapeIntersectionSceneQuery.cpp:52: error: 'class Ogre::PagingLandScapeSceneManager' has no member named 'getEntities'



OgrePagingLandScapeIntersectionSceneQuery.cpp:63: error: 'class Ogre::PagingLandScapePageManager' has no member named 'getPagingLandScapeRenderOpsInBox'

Thanks!

tuan kuranes

13-10-2005 21:31:53

there's no getEntities calls in the plsm2 sdk compatible source...
make sure you're compiling the SDK source.

This is the full code from OgrePagingLandScapeIntersectionSceneQuery.cpp from the .7z file you linked to:

My fault. This file is not meant to be compiled. I should have removed it from the cvs and distribution for ages.. sorry.

Check the vcproj file with a text editor to make sure you didn't include non compilable files. (it should be the only one...)

3dmacuser2

13-10-2005 22:02:28

Edit: Sorry, just had to include a more recent copy of stl_heap.h!

Edit2: Spoke too soon!

I'm getting errors now in OgrePagingLandScapeOcclusion.cpp

/usr/include/gcc/darwin/4.0/c++/bits/stl_heap.h:279: error: no match for call to '(Ogre::FrontToBackNodeSorterOperator) (Ogre::OcclusionElement*&, Ogre::OcclusionElement*&)'



/usr/include/gcc/darwin/4.0/c++/bits/stl_heap.h:166: error: no match for call to '(Ogre::FrontToBackNodeSorterOperator) (Ogre::OcclusionElement*&, Ogre::OcclusionElement*&)'

I'm confused by this... I don't see where stl_heap.h is even getting called from.

The lines in OgrePagingLandScapeOcclusion.cpp seem to be:



 void Occlusion::CHCtraversal(PagingLandScapeOctree *octree)

    {

        if (mIsQueryPoolNotInitiated)

            initQueryPool ();



        const Vector3 &camPos = mCurrentCam->getPosition();

	    FrontToBackNodeSorterPriorityQueue traversalStack = FrontToBackNodeSorterPriorityQueue(FrontToBackNodeSorterOperator (camPos));

and:



 //this is the algorithm from the paper, conservative way.

    void Occlusion::CHCtraversalConservative(PagingLandScapeOctree *octree)

    {

        if (mIsQueryPoolNotInitiated)

            initQueryPool ();



        const Vector3 &camPos = mCurrentCam->getPosition();

	    FrontToBackNodeSorterPriorityQueue traversalStack = FrontToBackNodeSorterPriorityQueue(FrontToBackNodeSorterOperator (camPos));

3dmacuser2

13-10-2005 22:43:14

Is the problem in OgrePagingLandScapeOcclusionSorter.h ?



namespace Ogre

{

   

    //comparator for priority queue

    class FrontToBackNodeSorterOperator 

    {



	    public:

            FrontToBackNodeSorterOperator(const Vector3& position) :   pos(position) {};

		    inline bool operator()(const OcclusionElement*& a, const OcclusionElement*& b) const 

            {

                // could check if both distance == 0 then order visible first ?

		        return vectorToBoxDistance (*a, pos) > vectorToBoxDistance (*b, pos);

	        }

I've got to admit that I am very inexperienced with C++, but shouldn't there be some code between the brackets there? Is this why it won't compile?

tuan kuranes

14-10-2005 07:41:36

it's stl related problem.
FrontToBackNodeSorterOperator is the comparator for a Priority Queue (which can be based on a heap, depending on STL implementations).

So problem in this stl implementation seems to be the const qualifier of the parameters :

try changing this



inline bool operator()(const OcclusionElement*& a, const OcclusionElement*& b) const

into this



inline bool operator()(OcclusionElement*& a, OcclusionElement*& b)

Great! That worked!

So, onto the next error

Thanks again for all this help, when I get it all working, if you want I'll add all these changes to CVS so it will be mac compatible.

So the next error is :

OgrePagingLandScapeOctreeSceneManager.cpp:1002: error: no matching function for call to 'Ogre::PagingLandScapeOctree::traversal(Ogre::ViewFrustumCullingTraversalDirect)'

Refering to this line:

                    case VIEW_FRUSTUM_DIRECT:

                            {

                                mPagingLandScapeOctree->traversal (ViewFrustumCullingTraversalDirect (mOcclusion));

What do you think?

tuan kuranes

16-10-2005 13:12:57

								ViewFrustumCullingTraversalDirect temp (mOcclusion);

mPagingLandScapeOctree->traversal (temp);

3dmacuser2

17-10-2005 01:54:11

Awesome!

I had to make some more changes, add some declarations and casts, and get rid of some identical symbols, but I managed to get it to compile and link!

I'll let you know if I can get the samples working

tuan kuranes

17-10-2005 08:48:51

Please post patches.

On Vc 7.1 there's not even a warning on the whole compilation...

As compilers have differents features and bugs, it's hard to make cross platform compiling effective without having the platform, that's why I need platform contributors.

3dmacuser2

17-10-2005 19:17:50

Ok, here's the error I'm reachin while compiling the sample:



Terrainlistener.h:43: error: no match for 'operator=' in 'i = ((CustomPagingLandscapeListener*)this)->CustomPagingLandscapeListener::mStaticGeometryList. std::map<_Key, _Tp, _Compare, _Alloc>::erase [with _Key = Ogre::String, _Tp = Ogre::StaticGeometry*, _Compare = std::less<Ogre::String>, _Alloc = std::allocator<std::pair<const Ogre::String, Ogre::StaticGeometry*> >](i)'

Occuring on this section:



 virtual ~CustomPagingLandscapeListener ()

        {

            StaticGeometryList::iterator i = mStaticGeometryList.begin ();

            while (i != mStaticGeometryList.end())

            {

                mSceneMgr->removeStaticGeometry(i->second);

	            i = mStaticGeometryList.erase(i);

                //++i;

            }

            mStaticGeometryList.clear();

        }

tuan kuranes

18-10-2005 07:24:41

new CVS just fixed that.

you can safely remove the erase line and uncomment the ++i.

3dmacuser2

18-10-2005 18:39:56

Ok, I got the samples to compile.

Unfortunately, it doesn't run. Here's ogre.log:

I thought the error might be because I hadn't run the mapsplitter yet. When I run the mapsplitter, with all the cfg files in the same directory as it, I get this error:

Yes you have to run it prior to demo. but it shouldn't crash. can you post the stack ?

that's not './MapSplitter' output but 'pngtest' output !?

3dmacuser2

19-10-2005 20:52:42

How can I get the stack after it crashes?

Yeah, I expected that if I ran without runing mapsplitter it would give me some sort of error, but I expected it to relate to resources, not a memory crash.

And as for mapsplitter, that's exactly what gets printed in my terminal when I run mapsplitter. Do you have any idea why it would be running pngtest instead? Does it do a pngtest first or something?

tuan kuranes

19-10-2005 21:10:16

about stack gdb should give it to you when segfault happens ?

don't know if it exist in osx but you can try

which MapSplitter
locate MapSplitter
ldd MapSplitter

and post output fo each of these

3dmacuser2

19-10-2005 21:18:26

nmartin:~/Downloads/OgreSDK/media/datasrcs natmartin$ which MapSplitter

/usr/bin/MapSplitter

locate MapSplitter gives the location of every file which contains MapSplitter.... and that's a lot.

And ldd doesn't exist.

Trying GDB when I have a chance.

tuan kuranes

20-10-2005 04:50:06

/usr/bin/MapSplitter ? that's rather strange.

and does locate MapSplitter gives a location where Plugins.cfg is too ?
(locate Plugins.cfg)
if yes this is the MapSplitter to run.

3dmacuser2

20-10-2005 19:35:52

That's just where I placed MapSplitter.

I first tried it in the same directory as plugins.cfg and all the datasrcs.
It did the same thing in both places.

tuan kuranes

20-10-2005 20:35:55

mapsplitter should be in the same director as paginglandscapedemo near resources.cfg, plugins.cfg, etc...

could you run gdb on mapsplitter et see where it goes ?

Hi there !

I'm trying to compile PLSM from CVS, I got Ogre CVS Head and it almost compile. I just get one error :
(I am not at my own computer now, but I remember)

In filetutil.c :
free was not declared in this scope.

I changed the #include <malloc.h> to <malloc/malloc.h> (that's the default place on Mac and ifdef'ed __APPLE__ to be sure.
Now I don't really know what to do, that's the only place I've seen this error (Ogre compiled just fine).

If someone could give me light on this, thanks ;-)

Thanks...
