who can help me

[MatthijsBurgh]

Please provide more info

[ghanta1996]

I having the same issue. I'm trying to build ROS2 Jazzy from source on MacOS. The compilation fails only at this point.

Can anyone help? Thanks

[MatthijsBurgh]

@ghanta1996 please provide more info than that you are building on MacOS. We don't support MacOS. So when you want any help provide as much information as possible.

Also provide info on which pybind version is being used

[ghanta1996]

@MatthijsBurgh Thanks for the response. I'm using pybind 11 (Version: 2.11.1). The build is mainly failing at the

pybind11_vendor/include/pybind11/operators.h: 187 PYBIND11_UNARY_OPERATOR(hash, hash, std::hash<L>()(l))

I was able to build with this commit - 6480921b236baacf282d32857c9a4a1c6f9bd971 which doesn't have hash impl

[MatthijsBurgh]

I think your issue is the same as https://github.com/orocos/orocos_kinematics_dynamics/issues/447

[MatthijsBurgh]

Please try my new commit, 05b1676b75494d7cd6f3b66d26ac4e09d4ba6485. It is probably still failing.

[AndriiNeverov]

Please try my new commit, 05b1676. It is probably still failing.

I tried building (using the "Without catkin" instructions for the base library and then the bindings) with the previous commit (i.e. with 03568ed) and it was failing on 15.6.1 M4 the same way it fails when I build ROS2 (versions Jazzy/Kilted/Rolling with Python 10 or 11):

[ 16%] Building CXX object CMakeFiles/PyKDL.dir/PyKDL/frames.cpp.o In file included from /Users/aneverov/src/orocos_kinematics_dynamics/python_orocos_kdl/PyKDL/frames.cpp:28: In file included from /Users/aneverov/src/orocos_kinematics_dynamics/python_orocos_kdl/PyKDL/PyKDL.h:28: /Users/aneverov/src/orocos_kinematics_dynamics/python_orocos_kdl/pybind11/include/pybind11/operators.h:187:37: error: call to implicitly-deleted default constructor of 'std::hash<Vector>' 187 | PYBIND11_UNARY_OPERATOR(hash, hash, std::hash<L>()(l))

but the HEAD (ca8634d) builds just fine.

@MatthijsBurgh Could you please release the new 1.5.2 version?

[MatthijsBurgh]

@AndriiNeverov I have released 1.5.2
