Hello, I have the same situation and fix it after change the gtsam version. But I am not sure which version I used before(now is "libgtsam-dev is already the newest version (4.0.3-1ubuntu1)" output from command "sudo apt install libgtsam-dev libgtsam-unstable-dev").I don't know if this will help.

Thank you for your help! I installed gtsam by compiling the source code from https://github.com/borglab/gtsam.git. I will try your method.
