Hi guys,
I'm trying run an OSG example on the iPhone simulator. First of all I
downloaded the new Release 3.0.1. Then I run this cmake command:
ccmake -G Xcode \
-DOSG_BUILD_PLATFORM_IPHONE_SIMULATOR:BOOL=ON \
-DBUILD_OSG_APPLICATIONS:BOOL=OFF \
-DCMAKE_OSX_SYSROOT:STRING=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk
\
-DBUILD_OSG_EXAMPLES:BOOL=ON \
-DOSG_BUILD_FRAMEWORKS:BOOL=OFF \
-DOSG_WINDOWING_SYSTEM:STRING=IOS \
-DCMAKE_OSX_ARCHITECTURES:STRING=i386 \
-DOSG_GL1_AVAILABLE:BOOL=OFF \
-DOSG_GL2_AVAILABLE:BOOL=OFF \
-DOSG_GLES1_AVAILABLE:BOOL=ON \
-DOSG_GL_DISPLAYLISTS_AVAILABLE:BOOL=OFF \
-DOSG_GL_FIXED_FUNCTION_AVAILABLE:BOOL=ON \
-DOSG_GL_LIBRARY_STATIC:BOOL=OFF \
-DOSG_GL_MATRICES_AVAILABLE:BOOL=ON \
-DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE:BOOL=ON \
-DOSG_GL_VERTEX_FUNCS_AVAILABLE:BOOL=OFF \
-DDYNAMIC_OPENSCENEGRAPH:BOOL=OFF \
-DDYNAMIC_OPENTHREADS:BOOL=OFF \ ..
Then I open the project-file. After that I have to change the base SDK to 4.3
because the sdk is set to 3.2.
Then I try to run the target example_osgVieweriPhone.
The building works but i get a weird linker error:
