Re: [osg-users] [build] how to build basicGeometry example?
Hi,
thanks for the help. I am on debian there it seemed i must use lower-case
find_package(osg), not OSG.
the line
target_link_libraries(testProjectMain ${OSG_LIBRARY} ${OPENTHREADS_LIBRARY})
works with "OpenThreads" , but ${OPENTHREADS_LIBRARY} it cannot find
Thank you!
Cheers,
Thomas

Re: [osg-users] [build] how to build basicGeometry example?
Hi,
it seems like it found the headers and is breaking on linking.
I attach a CMakeLists.txt I use for simple test apps. It assumes OSG is
installed and the linker can find it (e.g. mine is installed in
/usr/local and /usr/local/lib is added in /etc/ld.so.conf).
You could also have a look at FindOSG module in the latest cmake versions.

file and put into it:
PROJECT(testProject)
ADD_EXECUTABLE(testProjectMain

then i switched into test-build/ dir and run "ccmake ../test-src/" then i run
"make" and the output is:

How can i let cmake know that it should use osg header/libs? Is there anywhere
online a tutorial which explains the building of e.g. the examples? i did not
find anything,sorry.
thanks for help

Re: [osg-users] [build] how to build basicGeometry example?
Hi Thomas,
you need to do a couple of things, first take a copy of the
CMakeModules folder of OSG itself :
http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/CMakeModules
Then you need to tell CMake via your CMakeLists.txt where to find those
set(CMAKE_MODULE_PATH "PATH_TO/CMakeModules;${CMAKE_MODULE_PATH}")
# this will include and run CMakeModules/FindXXX.cmake
find_package(OpenThreads)
find_package(OSG)
include_directories(${OSG_INCLUDE_DIR})
project(testProject)
add_executable(testProjectMain
main.cpp
)
target_link_libraries(testProjectMain ${OSG_LIBRARY} ${OPENTHREADS_LIBRARY})
