@fzdm2005 did you ever get a resolution for this? I just ran into the same problem

Edit: nevermind, it seems that my error was slightly different but also occurred when trying to pip install dubins. My error ended up being:

 dubins/dubins.c: In function ‘PyInit_dubins’:
    dubins/dubins.c:4497:34: error: ‘PyTypeObject {aka struct _typeobject}’ has no member named ‘tp_print’; did you mean ‘tp_dict’?
       __pyx_type_6dubins__DubinsPath.tp_print = 0;
                                      ^~~~~~~~
                                      tp_dict
    dubins/dubins.c:4502:54: error: ‘PyTypeObject {aka struct _typeobject}’ has no member named ‘tp_print’; did you mean ‘tp_dict’?
       __pyx_type_6dubins___pyx_scope_struct__sample_many.tp_print = 0;
                                                          ^~~~~~~~
                                                          tp_dict

To workaround my error, I downgraded my python from 3.9 to 3.8. Related thread here: https://bugzilla.redhat.com/show_bug.cgi?id=1791745

An alternative solution is to install the package from source if you want to avoid downgrading python, i.e.

1. clone - git clone https://github.com/AndrewWalker/pydubins
2. remove the cython generated dubins.c file - rm dubins/dubins.c
3. build - python setup.py build_ext --inplace
4. Install with pip - pip install .

@rdesc Hello! How to use package after I installed it using your instrcutions? Simple "import dubins" don't work

Edit: Just figured it out. All you need is to append your path to dubins package

import sys
sys.path.append("###path to dubins package###")
import dubins

As an update. I tried to make this work with python 3.9 and came across the following error

Error compiling Cython file:
------------------------------------------------------------
...
        ts = []
        def f(q, t):
            qs.append(q)
            ts.append(t)
            return 0
        core.dubins_path_sample_many(self.ppth, step_size, callback, <void*>f)
                                                           ^
------------------------------------------------------------

dubins/dubins.pyx:123:59: Cannot assign type 'int (double *, double, void *) except? -1' to 'DubinsPathSamplingCallback'. Exception values are incompatible. Suggest adding 'noexcept' to type 'int (double *, double, void *) except? -1'.

Simple fix is change this line https://github.com/AndrewWalker/pydubins/blob/4ee7e76b95304cbebb3a505f5f483a28403f5dc5/dubins/core.pxd#L35

To the following:

    ctypedef int (*DubinsPathSamplingCallback)(double q[3], double t, void* user_data) except? -1

And then building with cython python setup.py build_ext --inplace should work fine
