Re: [osg-users] osgAL now has a CMake script

[Wang Rui]

Hi Sukender,

I have tested osgAL on Arch Linux 0.72 and GCC 4.0.3. It also works after
some changes. :-)

First, I think there should be an important definition for openalpp. Modify
the CMakeLists.txt in src/openalpp:

add_definitions(
 -DOPENALPP_EXPORTS
 -DOPENAL_VERSION=2007
 #-D_USRDLL
)

Otherwise I got lots of compile errors because of missing the OpenAL
version. The OPENAL_VERSION macro had been defined in the configure.in before
and maybe it could be made as an CMake option to users from now on.

And I would suggest do a few changes to the FindOGG.cmake, especially the
FIND_LIBRARY(OGG_LIBRARY ...) macro, to make it work in Linux. See
attachment for details.
Cheers,

Wang Rui
