Solution: Set GTSAM_USE_SYSTEM_EIGEN=ON
in the GTSAM CMakeCache.txt file.
Hey @BMannell, I am an amateur opencv enthusiast facing the same error as you were earlier, and I also tried setting the GTSAM_USE_SYSTEM_EIGEN=ON in the CMakeCache.txt file, but somehow it did not resolve my error. Could you tell what possibly could be the reason for that and how can I resolve it. Thanks :)
@Conjuror1279 Sorry, I'm afraid I won't be able to help much. I've probably re-installed Ubuntu 3 or 4 times since getting this error and I don't really remember what steps I took during this setup.
@BMannell Thank you for your reply, I will see if I can find anything on the internet about the issue.Thanks anyways :).
Note that your "set(GTSAM_USE_SYSTEM_EIGEN ON)" command needs to be placed after "include(cmake/HandleEigen.cmake)". Because in HandleEigen.cmake, GTSAM_USE_SYSTEM_EIGEN will be initialized to off by default.
I'm getting a strange error when running ./update.
It seems similar to #6.
Is there a way to enforce either GTSAM or BLAM to use a specific version of Eigen? GTSAM seems to come packaged with a version of Eigen, is there some way to get it to use the previously installed version? How can I tell which version is being used in order to align the versions of the other package?
