Update:
Ran into a different error related to Poco xml which turned out to be a gcc compiler version issue (v5 vs v4). Downloaded the gcc 5 compiled library which solved the library undefined reference error.
Update:
I pulled the stable version of openframeworks and the stable version of ofxCv which seemed to clear the error below.
Hi. I have built the example-file module on the Raspeberry Pi in the past so I know it does work. I am building on Ubuntu in a Virtualbox this time around and am running into a compile error with example-smile. Is this a version issue with openframeworks (pulled from master today), opencv (2.4.13) or ofxCv? BTW, I copied over the Raspberry Pi version I had over and still ran into the same error. Othe openframework examples are compiling successfully (e.g. polygonExample).
