ImportError: No module named __builtin__

[icepng]

error like this, but it's ok when i run the sample bin "who".
files generate by BB-weightv4.py

rg@rg-virtual-machine:~/vuzzer$ python runfuzzer.py -s '/home/rg/vuzzer/bin/vlc %s' -i 'datatemp/vlc/' -w 'idafiles/vlc.pkl' -n idafiles/vlc.names -o '0x00000000'

and i can "import builtin " in the python command.

i try to generate who.names and who.pkl by BB-weightV4 in IDA, and got the same error.
is the version of IDA pro make sense, my IDA is 6.6

[tosanjay]

We are using IDA 6.8. Can you please send me your generated .pkl/.names files?

[Mizari]

Got the same problem, was using IDA 6.8. Here are .pkl/.names files. Files were generated on IDA Windows though

https://transfer.sh/UJRs7/file.names
https://transfer.sh/uo0B2/file.pkl
https://transfer.sh/PpDJ1/libmagic.so.names
https://transfer.sh/11Q6Tz/libmagic.so.pkl

As you created pickle files on Windows and then opened them on linux, this issue will pop up. See the link: http://stackoverflow.com/questions/1849523/is-pickle-file-of-python-cross-platform
I will try to update this part in the next release.
thanks

[Mizari]

So, one has to make .names/.pkl files with IDA6.8 (not really a linux thing), and use them in Ubuntu, is that correct?..

Still http://stackoverflow.com/questions/1849523/is-pickle-file-of-python-cross-platform says that pickle is cross-platform (my versions are even the same on Windows and on Linux). After removing trailing \r's the bug still remains.

[Mizari]

Changed __builtins__ to builtins in .names files (and removed \r's) -> problem solved.
command "import __builtins__" failed in python, but "import builtins" didnt.
I used standart environment: Ubuntu 14.04, kernel 3.16.0-33-generic, python 2.7.6

Although now I've got this one:
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 763, in run
self.__target(*self.__args, **self.__kwargs)
File "runfuzzer.py", line 625, in main
gau.prepareBBOffsets()
File "/home/mizari/progs/vuzzer/gautils.py", line 510, in prepareBBOffsets
tBB=pickle.load(pFD)
File "/usr/lib/python2.7/pickle.py", line 1378, in load
return Unpickler(file).load()
File "/usr/lib/python2.7/pickle.py", line 858, in load
dispatch[key](self)
KeyError: '\n'

I think I did something wrong with removing \r's here

[lzyplayer]

The problem would be the file's difference between Linux(Unix) and windows .
.pkl and .names are generated in win ,which makes its space and enter different with linuxs' .
however , use linux apt dos2unix to change the format of .pkl .names .
the problem is gone.
It maybe the solution to this Issue.But still, i'm not sure if other problem would cause the same error.
