[sage-devel] Building sagemath 10.2 on Fedora 38

[Rafel Amer Ramon]

Hi!,

I have successfully build sagemath 10.1 on a Fedora 38 computer but now, when a I try to
build sagemath 10.2 in the same computer, I have a lot of errors in Cythonizing files

The first one is:

[ 19/557] Cythonizing sage/arith/rational_reconstruction.pyx
Error compiling Cython file:
------------------------------------------------------------
...
    """
    Return ``t.__new__(t)``.  This works even for types like
    :class:`Integer` where we change ``tp_new`` at runtime (Cython
    optimizations assume that ``tp_new`` doesn't change).
    """
    return (<PyTypeObject*>t).tp_new(t, <PyObject*>NULL, <PyObject*>NULL)
                                       ^
------------------------------------------------------------

sage/ext/stdsage.pxd:22:40: Cannot convert 'PyObject *' to Python object

Error compiling Cython file:
------------------------------------------------------------
...
    """
    Return ``t.__new__(t)``.  This works even for types like
    :class:`Integer` where we change ``tp_new`` at runtime (Cython

    """
    return (<PyTypeObject*>t).tp_new(t, <PyObject*>NULL, <PyObject*>NULL)
                                                        ^
------------------------------------------------------------


but I seems that there are no differences between the files


sage/arith/rational_reconstruction.pyx

in sage-10.1 and sage-10.2.



Another error is in

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/root/rpmbuild/BUILD/sage-10.2/src/./setup.py", line 118, in <module>
    extensions = cythonize(
                 ^^^^^^^^^^
  File "/usr/lib64/python3.11/site-packages/Cython/Build/Dependencies.py", line 1103, in cythonize
    result.get(99999)  # seconds
    ^^^^^^^^^^^^^^^^^
  File "/usr/lib64/python3.11/multiprocessing/pool.py", line 774, in get
    raise self._value
Cython.Compiler.Errors.CompileError: sage/arith/multi_modular.pyx
************************************************************************

and the differences between the the files

sage/arith/multi_modular.pyx

in sage-10.1 and sage-10.2 are

diff sage-10.1/src/sage/arith/multi_modular.pyx sage-10.2/src/sage/arith/multi_modular.pyx

The version of python installed is 3.1.6.

Anybody knows why have I these errors?
