Hello list,
I have some minor problems with the FindOpenSG.cmake script:
When installing OpenSG2, the default library directory is PREFIX/lib64.
However,
the FindOpenSG script searches only for PREFIX/lib. Another issue that did come
up
is that you can't call find_package(OpenSG) more than once, because the script
imports the OpenSG-libraries and cmake can't have a library defined more than
once.
I have included a patch below, which adds lib64 to the library search paths and
only
imports the libraries once. Can someone have a look at it and maybe incorporate
it
in the repository?
My second problem is related to osg2-config:
For some reason, the boost include directory is not added to osg2-config. For
this
reason I get errors like this one all over the place:
jkuvrc/packages/OpenSG/OpenSG-2.0.0-pre1-svn2422-boost_1_43_0/include/OpenSG/OSGBaseTypes.h:50:28:
error: boost/mpl/if.hpp: No such file or directory
The IMO relevant section of osg2-config is:
## Dependecies for OSGBase
"OSGBase" : {
"dep_osg_lib" : [ ],
"dep_lib" : [ "dl", "pthread", ],
"dep_lib_dir" : [ "/usr/lib64", ],
"dep_inc_dir" : [ ],
},
I guess the boost-include-directory should show up here inside "dep_inc_dir"?
How can I influence the value for this, so I can supply a patch?
Cheers,
Johannes Zarl
