GTSAM was built against a different version of Eigen

[hardesh]

Description:
I built gtsam with and without the default eigen. Still getting the error

• Operating system and version (e.g. Ubuntu 16.04 or Windows 10): ubuntu 16.04 with ROS kinetic
• Did you change the source code? (yes / no): no

I added message in the CMake to check whether the gtsam was getting built with the proper version and I was able to see the message output on the terminal window.

Having the same issue when building kimera_ros. Any update on this? It seems that if I build gtsam with the bundled eigen version KimeraRPGO fails to build but I can build Kimera-VIO. If I build with the system version of eigen I can build the RPGO but not the VIO. the wrapper fails to build with either eigen version

[hardesh]

I built GTSAM separately from source. I stopped getting this issue. But I am not able to build KimeraVIO package. My laptop crashes everytime I try to build the package. I am still not sure why this is happening.

[jbdaniel18]

Interesting. I am able to build KimeraVIO if I force GTSAM to use the bundled version of eigen. But KimeraRPGO will not build if the bundled eigen version is used. KimeraRPGO gets the error "/devel/include/gtsam/base/OptionalJacobian.h:22:23: fatal error: Eigen/Dense: No such file or directory". kimera_ros still gets "/devel/include/gtsam/base/Vector.h:72:1: error: static assertion failed: Error: GTSAM was built against a different version of Eigen" regardless of which eigen version I am building gtsam with

@jbdaniel18 what Ubuntu are you using?
It seems this issue is related to Ubuntu 16.04 only, just to check.

[jbdaniel18]

I am using Ubuntu 16.04

[hardesh]

I am also using Ubuntu 16.04

[Xcrater]

Hi, I am able to build KimeraRPGO but Kimera VIO fails. I am using Ubuntu 16.04 as well.

Hi, I am using Ubuntu 16.04. I found the problem is that the package pcl_ros relies on Eigen 3.2.92 in /usr/include. I replace it with Eigen 3.3.7 and build successfully. But it may cause other problems.
I test it on EuRoC dataset. It can work, but there is a red on terminal Attempt to register LCD/PGO callback, but no LoopClosureDetector member is active in pipeline.

[ToniRV]

Thanks @673402618 ! The error message can be safely ignored. It is just that the Loop Closure detector is not activated.

[roelofvandijk]

Same issue, fixed by upgrading system eigen in /usr/include/eigen3 to Eigen 3.3.7. Thanks @673402618.

[mzahana]

@roelofvandijk can you please describe how you updated Eigen? Is it through source or apt-get?

[mzahana]

I was able to fix the problem by setting GTSAM_USE_SYSTEM_EIGEN=ON:

catkin build --cmake-args -DCMAKE_BUILD_TYPE=Release -DGTSAM_USE_SYSTEM_EIGEN=ON

[hardesh]

Switched to Ubuntu 18.04 and ROS melodic. I did not come across this issue after that.
