I tried pyrexc in pypy/tool but i get the same error as with the normal pyrexc:
bash-2.05b# dist-pypy/pypy/tool/pyrexc test.pyx
/root/imp/test.pyx:5:17: Declarator should be empty
/root/imp/test.pyx:5:17: Expected '>'
The pyrex generated code looks like this:
cdef object hi__2ad67a3c():
# untyped variables: v0 v13 v21 v3 v7
v3 = <Function sys_stdout>()
v7 = <Function print_item_to>('hello world', v3)
v13 = <Function sys_stdout>()
v21 = <Function print_newline_to>(v13)
v0 = None
which was generated from a function that looks like this:
def hi(): return 'hello world'
