[osg-users] osg-users Digest, Vol 138, Issue 27

Wed Jan 2 03:17:00 PST 2019

Hi ??

Could you sign with you name so we know how to address you.

Could you also avoid replying to a digest as it just includes lots of
completely irrelevant topics.

Finally, it kinda sounds like you are asking basic C++ developer
questions.  Including headers and libs is so basic C++ programmer
question that it really isn't something for the OSG community to help
you with.  There are plenty of C++ resources online that will be a
better source of help.

Cheers,
Robert.

Robert.
