fmt compilation error about open3d_slam HOT 6 CLOSED

Hi @braca51e,
Did you install open3d from source, or used the given ppa?
When following the installation instructions in open3d_catkin (https://github.com/leggedrobotics/open3d_slam/blob/master/open3d_catkin/README.md) the ./install_deps.sh script includes libfmt-dev.
When using the ppa, this should not be needed, but we can check again on our end.

I did not install from source! I was able to compile successfully after I added fmt packakge in the cmakefile for open3d_conversions. I guess my fmt version was not compatible

Okay, thanks a lot for your follow-up e-mail. We will test the implications and potentially include it in the next release. Until then we will leave this issue open, in case somebody else encounters the same issue.

Hi, when i use EXPERT WAY: Build Open3d from source, i meet the same error

 fatal error: fmt/core.h: No such file or directory #include <fmt/core.h>

i think we should add ${Open3D_INCLUDE_DIRS}/open3d/3rdparty in the open3d_catkin

catkin_package(
INCLUDE_DIRS
${Open3D_INCLUDE_DIRS}
 ${Open3D_INCLUDE_DIRS}/open3d/3rdparty
)

Hi @mengchongxi,
Thanks a lot for your message. I tried to make the documentation a bit clearer in this PR: #37

I tried all three scenarios and for me as well as in a docker it works. Feel free to reopen the issue, if the problem still persists

@mengchongxi okay we also improved the open3d_catkin package :) maybe you can give it a try again and let us know?
Best,
Julian
