Dear mailing list
I am trying to compile a program with Cython using the compiler directives and
I am running into some trouble. Specifically, I am trying to port a Cython 0.18
program to Cython 0.19 and due to changes how char * and Python str are
handled, I need to set the c_string_encoding directive. Unfortunately, this
fails for my project and also in the following testcase when I try to do it
locally:
cimport cython
cdef class TestClass:
def foo(self):
with cython.c_string_encoding("ascii"):
return
If I replace the directive with "with cython.boundscheck(True):" the program
compiles fine. Also adding "#cython: c_string_encoding=ascii" as the first line
of the file works fine. However, adding a decorator
'@cython.c_string_encoding("ascii")' to foo also crashes the compiler. Finally,
compiling with "-X c_string_encoding=ascii" also works.
I was following the documentation provided here
http://docs.cython.org/src/reference/compilation.html . The error message that
I get is attached at the end. Did I do something wrong or can somebody point me
in the right direction?
Best regards
Hannes Roest
