openFABMAP installation problem

Hi. I'm trying to install openFABMAP and having a few problems.
When I type in make after building, I get the following message.

I am currently using openCV 2.4. I would really appreciate any help.
Thank you!
On which OS are you building? On ubuntu 18.04 and opencv version 2.4.13.7 I am not getting any errors. It does appear to be an opencv version error though, maybe double check the version you are compiling against if you also have opencv 3.X installed.
Currently on ubuntu 16.04 and opencv 2.4.13. I tried uninstalling and reinstalling opencv a few times but still get the same error. I don't really know where to start. Any suggestions on what I could try?
Thank you!
I've been using the code in googlecode project so I tried it using the one in the git and got the following error.

Is it a similar problem as the first? I've checked that I have opencv 2.4.13 and not opencv 3.
It looks like the version of opencv that you are finding is 3.3 - it probably comes bundled with ROS. To solve this do a "ccmake .." in the build folder and manually change the path of the opencv to the location of opencv2.4. The location will change depending on how you installed it.
I'm currently updating the code to work with opencv3, but haven't quite finished.
