Error in bdb.make

Hi, I am facing the following error when I try to compile the binaries. I use Matlab R2017b with Ubuntu 17.10. Would you help me how to solve this problem? Thank you.

@tammytammy Seems the old mexopencv fails to build, replace that with the latest version. Get the latest from https://github.com/kyamagu/mexopencv

Regarding bdb, I do not know how Matlab R2017b treats the hidden mxSerialize API. You probably have to manually fix this part. See https://undocumentedmatlab.com/blog/serializing-deserializing-matlab-data
