9 years ago Hello everyone,
I managed to successfully compile the package. Here is what was going wrong -
The issue was primarily with the linking of the libraries in CMake, and with dependencies / paths of the libraries installed. I first went through CMake documentation thoroughly, especially using external libraries with and without existing cmake modules. I then set the variables that FIND_PACKAGE is supposed to set (for example, G2O_INCLUDE_DIR, SUITEPARSE_INCLUDE_DIR, etc.), accordingly.
I also explicitly linking cxsparse and some of the G2O libraries with my executables, since they weren't getting linked (by the looks of it), using target_link (${G2O_LIBRARIES}), etc. I really advise anyone facing similar issues to go through how Cmake works first.
Hey,
I am trying to compile ccny_rgbd_tools (master branch) on ROS Hydro, ubuntu 12.04. (After struggling with issue #42 ).
I run the rosdep install command, and it installs libg2o. (ros-hydro-libg2o). Then I get these errors:
Linking CXX shared library lib/librgbdtools.so make[3]: Leaving directory

I tried manually including these, but it still comes up as errors.

Any suggestions as to how I can solve this inconsistency, guys? @idryanov
Thanks in advance!
EDIT 1: I managed to sort out the g2o::get_monotonic_time() error by compiling this along with ccny_g2o , after setting up CMakeLists accordingly.
