Hi,
In order to do some numerical ODE work quickly, I was defining all my
functions with cython. The recent 2.8.7 upgrade seems to have broken
several of these functions. As one example, the following definition
attempt:
%cython
cdef Circ(t):
return (cos((t/365.0)*2*RDF(pi)) + 1)/2
gives a bunch of errors starting with:
Traceback (most recent call last): cdef Circ(t):
File "/Volumes/D/sage-2.8.4.1/local/lib/python2.5/site-packages/sage/
server/support.py", line 303, in cython_import_all
create_local_c_file=create_local_c_file)
File "/Volumes/D/sage-2.8.4.1/local/lib/python2.5/site-packages/sage/

File "/Volumes/D/sage-2.8.4.1/local/lib/python2.5/site-packages/sage/

log, err)

include "cdefs.pxi"
cdef Circ(t):
return (cos((t/365.0)*2*RDF(pi)) + 1)/2 ^

Any help is appreciated, I don't have much understanding of cython.
