Problem building Opencv 3.1 - cap_gphoto2.cpp errors

edit

I've been running into the same problem with both the release version of 3.1 and the current cloned version of the repository. The problem appears to be in the videoio module when compiling the cap_gphoto2.cpp file. I've run into this issue on two separate computer systems both running RHEL 6.6. Here's the relevant error messages: At the end of the post is the configuration output and the error log.
