The Wiki and Google Code docs are a bit light on the external dependencies and build instructions required to enable iv. I think we should have a section in the INSTALL doc and on the wikis that describe the steps needed to download, build and install the dependencies required for iv. I'm happy to make these changes to the wiki (assuming I have permissions), but I wanted to make sure that this is the right way to install and build iv with Qt before I added any instructions.
What's the best way to download and install Qt for OSX? The Qt download link is wrong. I think the new link is http://qt.nokia.com/downloads/ But I'm not sure that's the best installer. I used it and it worked, but I wasn't sure if I should use the MacPorts version, and, if so, how to install it (yes, maybe I should know how to install MacPorts packages, but I don't use them for anything at all except OIIO and I have no desire to learn about them, I just want a simple instruction in our docs). Can I delete all the extra crap after installation? Does the MacPorts installation of Qt install a smaller set of stuff? Which one do we want to recommend? Once I had Qt installed, I had to look in the Windows build instructions to figure out how to set the QTDIR. CMake didn't find it in my home directory. Maybe that works better with MacPorts? If not, I think we should add this to the wiki for the OSX build instructions. I set QTDIR in my .profile and added $QTDIR/bin to my path and that seemed to make CMake happy about the QT_INCLUDES but not the QT_LIBRARY, but, despite QT_LIBRARY being blank in the CMake diagnostics, it seems to work. Next I had to download, build and install GLEW, which was pretty simple, but still annoying. We should include a link and simple build and install directions (make; sudo make install). I also think we can do a bit better with the instructions for installing the various external test image directories. You need to look at the CMake output to figure out where to install these images, the JPEG2000 link is busted, and the FITS link has lots of subdirectories with no single TGZ file. Dan
