Freeze tool can generate Makefile and C code for Python programs using the JSON module. The code can be compiled fine, but when a program using the JSON module is run, this is returned:

Traceback (most recent call last): 
2	  File "myProgram.py", line 15, in <module> 
3	    import json 
4	  File "/usr/local/lib/python2.7/json/__init__.py", line 108, in <module> 
5	    from .decoder import JSONDecoder 
6	  File "/usr/local/lib/python2.7/json/decoder.py", line 24, in <module> 
7	    NaN, PosInf, NegInf = _floatconstants() 
8	  File "/usr/local/lib/python2.7/json/decoder.py", line 18, in _floatconstants 
9	    _BYTES = '7FF80000000000007FF0000000000000'.decode('hex') 
10	LookupError: unknown encoding: hex 

Something to do with .decode('hex') apparently.

Problem occurs with "frozen" programs if:


from encodings import hex_codec 

...is not explicitly written in the script.

Similar problem occurs if you do not specify

   from encodings import ascii

You can get

   LookupError: unknown encoding: ascii
