Macintosh Version - Testing Needed

An "experimental" Mac OSX version of PagedGeometry is now availible for download here (thanks to kordeul):

PagedGeometry SDK for Mac OSX (experimental) - 3.75 MB
Includes tutorials, examples, and API documentation.

According to kordeul, the impostor generation fails in this OSX version, although it seems to work fine in Windows / Linux. If you are a Mac developer, please try compiling and running some of the examples here and see if you can confirm that the error exists on your computer as well. Kordeul hasn't had much time to debug this, and since I don't have a Mac, there's not much I can do to test & support Mac-only issues myself.

Hmm. I get the following problems:


Warning: Multiple build commands for output file /Users/ummonk/Desktop/Downloads/PagedGeometry/OSX/build/Release/PagedGeometry.framework/Versions/A/Resources/Info.plist
cd /Users/ummonk/Desktop/Downloads/PagedGeometry/OSX

pbxcp: Example1.app: No such file or directory


The samething happens for all the other Examples. For some reason it does not create the application bundles when I try to compile it. I tried creating a test target and that didn't work either.

Hmm.. well I can't help you much with non-code related issues here, since I don't know how the Mac build system works. Maybe someone else can help (but unfortunately it seems Mac users are in the minority here).

If you can help me in the right direction to find OIS.Framework so i can compile, i'd be more than happy to test

Hmm. I had googled and somehow found a framework for OIS, since the Ogre build only gives you libois.a, which is in the wrong format... Now I can't find out where I got the framework... So I just copied it to my website (please note that every once in a while it goes down so you may have to try again in an hour if it isn't working.) However, it is available at http://ummon.is-a-geek.com/OIS.tgz

Cheers and thanks alot

Ill try as soon as i get home from work tonight !

Im still having some linking problems, will look more into it this weekend...

I just managed to the it build't, but when i debug the examples i get this:

Hello.

I also played a bit around with it. But I am not an OpenGL expert, so I frighten I cannot help much.

Since I do not like complicated IDE setup, i hacked together a simple Makefile, which builds the thing on command line. Put the following with the name "Makefile" in the root of the directory structure.

# application name
TARGET = PagedGeometryExample

# global flags
CXXFLAGS += -pipe -ansi
EXTRA_CXXFLAGS = -D_DEBUG -DDEBUG -g
#EXTRA_CXXFLAGS = -O3
WARN_FLAGS = -Wall
INCLUDE += -Iinclude

INCLUDE += -I/Developer/OgreSDK/Dependencies/include -I/Developer/OgreSDK/Dependencies/Ogre.framework/Headers/
LIBPATH += -L/Developer/OgreSDK/Dependencies/lib/Release/
LIBRARIES += -framework Ogre -framework Cocoa -framework Carbon -lois

# combine the stuff
LIB = $(LIBPATH) $(LIBRARIES) $(EXTRA_LIBS)
CXXFLAGS += $(EXTRA_CXXFLAGS) $(WARN_FLAGS) $(INCLUDE) $(EXTRA_INCLUDES)

SRC_FILES = $(wildcard source/*.cpp) examples/source/Example1.cpp
O_FILES = $(SRC_FILES:%.cpp=%.o)

all: $(TARGET)

$(TARGET): $(O_FILES)
$(CXX) $(O_FILES) -o $@ $(LIB)

clean:
rm -f *.o source/*.o .gdb_history

This depends just on the Ogre SDK and uses libOIS.a provided with the SDK. On my system, the OgreSDK is located in /Developer/OgreSDK. So be sure to adjust the pathes before using this. Also verify, that the file uses tabs, not spaces, else make will be unable to parse this file.

By default, only Example1.cpp is build. Change the path locations... just remove all the voodoo. line 101, 189 and 191 for Example1.cpp

Should be the fastest way, to get a testing environment.

Hope this may help someone.

Have fun,
rTi

By the way, I get the following back trace when trying to run Example1

hey
great job !
i made my own xcode project of current version (1.02) and i must say this lib rocks

.tar.bz2 (with binaries) is http://deltanet.pl/~wyszynski/ogre/PagedGeometry-1.0.2-Mac.tar.bz2

btw, is this a bug (grass color)?
looking at the ground

looking forward
http://deltanet.pl/~wyszynski/ogre/grass_up.jpg

br, aljen

btw, is this a bug (grass color)?
It looks like a bug (the grass shouldn't be colored like that obviously). It almost looks like the fog is messed up on the grass and tinting all of it blue-ish. Could you try disabling fog on the example and see if that removes the issue?

without fog http://deltanet.pl/~wyszynski/ogre/wo_fog.jpg

Hmm. It appears the fog is somehow affecting the grass incorrectly. This is strange since grass with fog works fine on my computer under DirectX and OpenGL. Are your drivers all up-to-date?

P.S. I forgot to say: good job getting PagedGeometry to work on mac . Do you have impostor rendering issues like the other project files, or does it generate the Impostor.*.png files correctly?

I have this error message during Xcode compilation:

Building target “PagedGeometryâ€
