[Pyrex] Conditional Compilation

[Simon King]

Dear Pyrex group,

in 
http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/version/Doc/Manual/basics.html#Conditional_Compilation
i found that Pyrex 0.9.6 supports compile-time definitions and 
conditional compilation.

However, i didn't succeed to make it work, so far. Perhaps you can help 
me?

According to an example in the above link, i have a file "test.pyx" 
containing:

IF UNAME_SYSNAME == "Linux":
    def x():
        print "It works!"
ELSE:
    def x():
        print "Doesn't work"

However, pyrexc 0.9.6.2 (which is in my /usr/local/bin/) complains a lot:

Traceback (most recent call last):
  File "/usr/local/bin/pyrexc", line 8, in <module>
    main(command_line = 1)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Main.py", 
line 312, in main
    result = context.compile(source, options)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Main.py", 
line 188, in compile
    tree = self.parse(source, scope.type_names, pxd = 0)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Main.py", 
line 142, in parse
    tree = Parsing.p_module(s, pxd)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Parsing.py", 
line 1944, in p_module
    body = p_statement_list(s, level)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Parsing.py", 
line 1252, in p_statement_list
    cdef_flag = cdef_flag, visibility = visibility, api = api))
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Parsing.py", 
line 1201, in p_statement
    return p_IF_statement(s, level, cdef_flag, visibility, api)
  File "/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/Parsing.py", 
line 1173, in p_IF_statement
    s.compile_time_eval = current_eval and 
bool(expr.compile_time_value(denv))
  File 
"/usr/local/lib/python2.5/site-packages/Pyrex/Compiler/ExprNodes.py", line 
2923, in compile_time_value
    operand1 = self.operand.compile_time_value(denv)
AttributeError: PrimaryCmpNode instance has no attribute 'operand'


Can you explain to me what i did wrong?

Perhaps there was a path missing when i built pyrex: I work on 32/64 bit 
(x86_64), but there is only a /usr/local/lib/python2.5/, but no 
/usr/local/lib64/python2.5/ 

Can this be the reason? And how to fix it?

Yours
