Building with WSL does not work

[jerylteo]

Running WSL on Windows 11, on BehaviorTree.CPP v4.6.2.

Continuation from #867

Commands to build works without errors, but folder does not reflect built files. i.e. No difference made after running: cmake --build . --parallel

After running: ... [ 99%] Built target t12_default_ports [ 99%] Built target t06_subtree_port_remapping [100%] Linking CXX executable t11_groot_howto [100%] Linking CXX executable ex03_sqlite_log [100%] Built target t11_groot_howto [100%] Built target ex03_sqlite_log [100%] Linking CXX executable behaviortree_cpp_test [100%] Built target behaviortree_cpp_test

But build folder does not contain any lib or dll etc.

Did something go wrong? Running with administrative privileges did not make a difference.

Installing with Pixi works but program crashes because "libzmq-mt-4_3_5.dll was not found".

I've literally tried all ways I can think of to build this.

• Windows (sqlite3.h not found)
• WSL (build doesn't work)
• Pixi (libzmq-mt-4_3_5.dll was not found)
• Tried v4.5.x and v3.8, both does not work either.

Would appreciate some help.

Building with OSX replicates the issue.

I think the build works, but there could be some configuration that does not build a dll/lib for non-Windows OS. Unfortunately, I need to add this to a Windows VS Project, so I do need to be able to link the library over.

Looks like I've made one full circle and need to build in Windows, but that doesn't work. #867

Building it directly with VS fails to build the library with zmq and sqlite3 errors:

Removing ZMQ and SQLite3 from CMakeList allows the library to build properly.

However, when running a sample program on Debug mode, I get a Read Access Violation error from behaviortree_cppd.dll. Release mode works, but I need to be able to run in Debug mode. This error should be another topic. #869

Are you building with ROS2 by any chance? if so I have been adding https://github.com/tony-p/BehaviorTree.CPP/blob/e923c1fc412e2775cf1b5dbeae77cf7fd78525f0/cmake/ament_build.cmake#L7 for the pixi build to work.

Can't remember exactly why I haven't upstreamed it, either it broke the regular build or I thought it was just too hacky

On WSL/Linux with pixi/robostack I ended up manually linking the libraries https://github.com/RoboStack/ros-humble/issues/119

Not sure if this actually still an issue with behaviortree.CPP ZMQ as I believe the libraries are now linked as Public, but definitely had to do that in the past

[tony-p]

when you run with pixi, are you running it within the pixi environement?

pixi is built for a flavour of a conda virtual environment, so to run you should either use pixi shell to enter the pixi environment, or prefix your execution command with pixi run https://pixi.sh
