Hi,
This is a Linux machine and I am using Eclipse for development of a Qt app.
I installed OSG V 3.0.0 and found it did not have the Qt integration in it. I
then downloaded and built OSG V 3.0.1. I need to read a PNG image but find
that I have no osgdb_png.so in my 3.0.1 directory which is under
/usr/local/lib/osgPlugins-3.0.1. I do have it under my home directory
/OpenSceneGraph/lib/osgPlugins-3.0.0.
Can I just copy the 3.0.0 plugin to my 3.0.1 directory or is there a version
problem?
Why didn't my osgdb_png.so get placed in the 3.0.1 plugin directory along with
the rest of the plugins? How can I get it there?
What needs to be set up in order for the plugins to be found?
I now have 2 OSG versions on my computer. Can I safely get rid of the 3.0.0
version? How can I do that?
I'm guessing you installed OSG-3.0.0 from a package in your Linux
distribution. If so, you can use the regular package management system
for your distribution to remove OSG-3.0.0 (if you can tell us which
Linux distribution you have, we can probably give you more specific
instructions).
In order to build the osgdb_png.so plugin, you need the libpng
development libraries installed on your system (most likely, you only
have the runtime libraries, which doesn't include the headers needed for
development). If your distribution has a package called libpng-devel or
libpng-dev, you'll need to install that.
