Compiling error: G2O_SOLVER_CHOLMOD
Compilation with ROS error:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: G2O_SOLVER_CHOLMOD linked by target "svo" in directory /home/jay/catkin_ws/src/rpg_svo/svo
-- Configuring incomplete, errors occurred! Invoking "cmake" failed
If I compile with SET(HAVE_G2O FALSE), then the error disappears. This is inspite of the fact that I have previously built g2o.
The reason is due to the fact that we were compiling g2o, we missed the cholmod lib so that the G2O_SOLVER_CHOLMOD is not built at all. so solve it, do the following. $ sudo apt-get install libsuitesparse-dev libsuitesparse-metis-dev then build the g2o again and install to it as instructed.
Hope it helps.
Hi ningzhou, I am trying to build LSD-SLAM* (and new to programming) on Win8x64; Cmake 3.6.2 and a pre-built g2o. With Visual Studio 2015 (vc14) installed. Same problem when configuring with Cmake:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: G2O_SOLVER_CHOLMOD linked by target "sample_app" in directory C:/Users/xxx/LSD_SLAM/lsd_slam_noros-master/apps/slam G2O_SOLVER_CHOLMOD_DEBUG linked by target "sample_app" in directory C:/Users/xxx/LSD_SLAM/lsd_slam_noros-master/apps/slam
Not a lot to find.. tried rebuilding g2o from fresh (with EIGEN3) - but get even more errors then. Any idea??
*There is no "issues" page for that partical package (LSD-SLAM for Windows) so it's hard to ask there.
Much appreciated, thanks!
I had the same issue. I just deleted both ${G2O_SOLVER_CHOLMOD} and ${G2O_SOLVER_CHOLMOD_DEBUG} from the lsd_slam_noros\apps\slamCMakeLists.txt. After that CMake compiled without error, but I'm not sure if it breaks somewhere else now...
@Planchee Sorry for the late reply. I actually not very familiar with Windows. Are you able to set the path for G2O_SOLVER_CHOLMOD. The errors mean that both release and debug versions of the library cannot be found.
Install g2o from source (https://github.com/RainerKuemmerle/g2o.git) mkdir build cd build cmake .. make sudo make install
I still get that error and have tried everything mentioned above. Any help is appreciated thank you!
