initialization of io raised unreported exception

[ananevans]

I am trying to install the lanelet2 library using conan on an Ubuntu 20.04 distribution (python 3.8). Here is the output of:

conan install lanelet2/1.1.1@lanelet2/stable --build=missing -g virtualenv

The following tests FAILED:
	 26 - lanelet2_routing-gtest-test_relations (Failed)
	 27 - lanelet2_routing-gtest-test_route (Failed)
	 28 - lanelet2_routing-gtest-test_routing (Failed)
	 29 - lanelet2_routing-gtest-test_routing_graph_container (Failed)
	 30 - lanelet2_routing-gtest-test_routing_visualization (Failed)
/bin/bash: catkin_test_results: command not found

If I comment cmake.test() in conanfile.py, then the installation completes, but I get the following error:

Any suggestions on how to get the library to work are greatly appreciated.

Seems like you have to make conan build lanelet2 and boost as shared libraries. And you need virtualrunenv so that LD_LIBRARY_PATH is set. Basically like this:

conan install lanelet2/1.1.1@lanelet2/stable --build=missing --options shared=True --options boost:shared=True -g virtualenv -g virtualrunenv
source activate.sh && source activate_run.sh

Can you confirm this works? Then we'll update the docs to reflect this. This "double-sourcing" makes me a little sad, but it seems conan offers no better way to make it work. And it seems you cannot even properly deactivate this without breaking your shell...

I cleaned up any previous installation with:

pip uninstall conan
rm -rf ~/.conan
rm -rf lanelet2

I executed the updated commands:

pip install conan catkin_pkg
conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
git clone https://github.com/fzi-forschungszentrum-informatik/lanelet2.git
cd lanelet2
conan source .
conan create . lanelet2/stable --build=missing --options shared=True
conan install lanelet2/1.1.1@lanelet2/stable --build=missing --options shared=True --options boost:shared=True -g virtualenv -g virtualrunenv
source activate.sh && source activate_run.sh

You also need --options boost:shared=True for the create step:

conan source .
conan create . lanelet2/stable --build=missing --options shared=True --options boost:shared=True
conan install lanelet2/1.1.1@lanelet2/stable --build=missing --options shared=True --options boost:shared=True -g virtualenv -g virtualrunenv
source activate.sh && source activate_run.sh

It works now. Thank you!
