Hey,
I've encountered the same problem some time ago.
The problem was the macro in the CMakeLists.txt. On my system it hast to be
"_INCLUDE_DIRS" and "_LIBRARIES".
Try this osg-cmake project setup:
cmake_minimum_required(VERSION 2.8)
project(MyProject)
set(target MyProject)
find_package(OpenSceneGraph REQUIRED
osgAnimation
osgDB
osgGA
osgText
osgUtil
osgViewer
osgShadow
osgParticle
)
set(sources
src/main.cpp
)
include_directories(
${OPENSCENEGRAPH_INCLUDE_DIRS}
)
add_executable(${target} ${sources})
target_link_libraries(${target}
${OSG_LIBRARIES}
${OSGANIMATION_LIBRARIES}
${OSGDB_LIBRARIES}
${OSGGA_LIBRARIES}
${OSGTEXT_LIBRARIES}
${OSGUTIL_LIBRARIES}
${OSGVIEWER_LIBRARIES}
${OPENTHREADS_LIBRARIES}
${OSGSHADOW_LIBRARIES}
${OSGPARTICLE_LIBRARIES}
)
Also if you built osg from source and ran the install target, make sure your
OSG_DIR env variable point to your install directory specified in the cmake-gui
(e.g. c:/lib/osg/install), otherwise cmake could include the wrong header files.
Hope this helps.

Betreff: [osg-users] OpenSceneGraph for Beginners tutorial help requested
Hi,
I've been working with the OSG Beginners book. I am trying to get the first
program to run but I continually get a bad alloc error:
Code:
Microsoft C++ exception: std::bad_alloc at memory location 0x00a1d4f0..
The break point is:
Code:
inline osg::Node* readNodeFile(const std::string& filename)
{
return readNodeFile(filename,Registry::instance()->getOptions());
}
And the following is my code:
Code:
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
int main( int argc, char** argv ) {
osg::ref_ptr<osg::Node> root = osgDB::readNodeFile("c:\\osg\\data\\cessna.osg");
osgViewer::Viewer viewer;
viewer.setSceneData( root.get() );
return viewer.run();
}
Any hints would be fantastic.
Thank you!
Cheers,
Seth
