So I like the catkin build system and am interesting in using it outside ROS, and working with people that don't want to install ROS. Is this possible?

I've tried installing catkin with pip but am getting errors like unable to find catkinConfig.cmake. Before I start going down this rabbit hole and try copying just that file, has anyone tried this?

edit: I built from source and when I run catkin_make after sourcing /usr/local/setup.sh, I get this:

Base path: workspace
Source space: workspace/src
Build space: workspace/build
Devel space: workspace/devel
Install space: workspace/install
####
#### Running command: "cmake workspace/src -DCATKIN_DEVEL_PREFIX=workspace/devel -DCMAKE_INSTALL_PREFIX=workspace/ins\
tall" in "workspace/build"
####
CMake Error at CMakeLists.txt:59 (message):
  find_package(catkin) failed.  catkin was neither found in the workspace nor
  in the CMAKE_PREFIX_PATH.  One reason may be that no ROS setup.sh was
  sourced before.

I've tried setting /usr/local/share/catkin/cmake/ as CMAKE_PREFIX_PATH.

edit: ok, appears to have been a permissions issue and now catkin_make is working, but the directories created appear to be incompatible with catkin build now, which fails on its own. Is that command deprecated? It is how I create eclipse projects.

How did you build it from source?

What do you mean with "catkin build"? rosbuild or catkin_tools?

in order to get catkin working I needed to pip install catkin_pkg, and I also installed catkin_tools, which has the catkin (not catkin_make) commands. I used this to make separate eclipse projects for each module, while catkin_make -G"Eclipse CDT4 - Unix Makefiles" puts them in one big project.

catkin_tools has not officially been announced and is still in development. You might want to stick to the commands coming with catkin: namely catkin_make / catkin_make_isolated.

There is nothing wrong with catkin_tools, but you cannot mix usage of catkin build and catkin_make in the same workspace. You must use one or the other.

Fair enough, is there a way to make catkin_make build separate eclipse projects like catkin build does?

You might want to try catkin_make_isolated which invokes CMake for each package (the same way as catkin_tools).

You can either use catkin_make_isolated or use catkin_tools but with different build, devel, and install folders.

You can't install catkin via PIP. While it does have a setup.py file it is not a pure Python package.

You can either clone the repository and use catkin from source (and build it from source) or install the Debian package from the ROS apt repo. It only depends on CMake and a handful of Python packages but nothing ROS specific.
