Hello all,
I'd like to report a build error I encountered on Windows using CMake
2.4 and default CMAKE_INSTALL_PREFIX. The default value for the install
prefix is "C:/Program Files/OpenSceneGraph" (without the quotes). The
space in the path appears to confuse CMake when generating the project
file for osgDB. The problematic CMake source line is:
ADD_DEFINITIONS(-DOSG_DEFAULT_LIBRARY_PATH=${CMAKE_INSTALL_PREFIX}/lib${LIB_POSTFIX}/${OSG_PLUGINS})
CMake splits this line at the space, creating an output line of
"-DOSG_DEFAULT_LIBRARY_PATH=C:/Program" plus an additional compiler
option of "Files/OpenSceneGraph/lib/osgPlugins-2.8.0". The compiler
tries to compile this as a file and throws an error. Putting quotes
around the string for the CMAKE_INSTALL_PREFIX option fixes the problem.
In addition to noting this build problem, I would like to question the
desirability of storing the install path in the binary. The users of my
software certainly won't be installing OSG in a fixed path determined at
the time I compile the software, so best case here is a useless check of
a nonexistent directory. Worst case is that another build of OSG is in
that directory with plugins built with incompatible compiler options,
leading to a crash. I suggest removing this osg default library path or
having an option to disable it (preferably with disabled being the default).
Regards,
Mark
