compilation torch-ros

[LiliMeng]

Hi,

  Thanks a lot for providing the package!

  Could you provide some suggestion on how to compile it?

  Thanks a lot!

I downloaded it to the ~/catkin_ws/src file, and then
$cd torch-ros
$cmake .
It's good now. but after
$make
The following errors appear

@LiliMeng Nomally with ROS indigo installed you should be able to build the project with luarocks make in the directory where torch-ros resides. Seems as if the SerializeMessage specialization trick does not work on your system.

I seem to have a similar problem. I have indigo installed but it seems it's finding a hard time finding catkin.

I got the following errors:

CMake Error at CMakeLists.txt:7 (find_package):
  By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catkin", but
  CMake did not find one.

  Could not find a package configuration file provided by "catkin" with any
  of the following names:

    catkinConfig.cmake
    catkin-config.cmake

  Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
  "catkin_DIR" to a directory containing one of the above files.  If "catkin"
  provides a separate development package or SDK, be sure it has been
  installed.

Moving it to my catkin_ws src folder and building from there seems to solve the problem. Might be worth addressing this in your readme. Thanks!

@lakehanne, I tried that but I had no luck, I get that same error.

Is the /home/vkee/momap directory where you have your catkin workspace? Another note, do not use cmake in the src folder. You want to use catkin_make from within the root folder of your catkin workspace.

[vkee]

That is my catkin workspace.

I did that, but it said it finished building without building torch-ros at all.

[robotsorcerer]

Maybe delete your build folder and then re-catkin_make. Sometimes, the
cmakelists cache text files in the build directory doesn't get updated
unless you explicitly delete them. Don't forget to cd to torch-ros
directory afterwards and install the rockspec with luarocks.

You should be fine.

Sincerely,
Lekan

Hi, I am able to compile this on ros indigo but facing the compilation issue i.e message traits not defined for RawMessage, while compiling on ros melodic. Any idea how to solve it?
