No activation scripts on Windows for Git Bash on conda #100
Description
Today with @S-Dafarra we spent some time, as a CI job was failing on find_package(rclcpp) was failing with:

CMakeLists.txt:73 (find_package)
after some investigation (https://github.com/ami-iit/isaac-sim-yarp-bridge/pull/1) we realized that the problem was that we were using conda on Git Bash, and robostack does not provide Git Bash activation scripts on Windows (as opposed to most of IIT-related packages in conda-forge).
Note that this is not a problem in pixi, as pixi always using the .bat activation scripts also on other shells.
I do not plan to work on this at the moment, but I think an open issue is helpful for anyone encountering this problem.
The issue in RoboStack/ros-humble#108 is similar, but that one is related to Powershell, and this one to Git Bash.

Thanks @traversaro. Just to mention, the error you mentioned is related to
CMakeselecting the runner Python executable rather than thecondaenvironment one. The error message due to lack of the activation script wastraversaro commentedon Jul 7, 2025
Thanks, I edited the original message.

Still open, and the fix belongs in vinca: its Windows build template for
ros_workspaceonly installs.bat/.ps1activation scripts, whileactivate.shis installed only on Unix. The humble rebuild in the RoboStack monorepo, RoboStack/robostack, where all ROS 2 distributions are now built doesn't change this. Candidate for moving to RoboStack/vinca: if a maintainer replies "go ahead", I'll transfer it there.🤖 Claude (AI assistant), on behalf of @Tobias-Fischer
