Hi there,
Since 8.2.rc0 (the update to cython 0.28.1) I'm having trouble using
pyximport. Here is a minimal non working example:
######## minimal.py ############
import pyximport; pyximport.install();
from minimal_pyx import minimal_fun
######## end minimal.py ############
######## minimal_pyx.pyx ############
from sage.misc.cachefunc import cached_method
def minimal_fun():
print("hi")
######## end minimal_pyx.pyx ############
Running this with "sage minimal.py" fails as reproduced below.
It seems that I should somehow set the compile_time_env variable
'PY_VERSION_HEX', and set it to sys.hexversion. I don't know how to do
that (especially not when using pyximport), and I'm puzzled because I would
have thought that dict_del_by_value.pyx is already compiled...
Thanks for any hints or workarounds!
Martin
