Hi, I'm unable to decompile an intel 64 binary. The error is below:

Hi,

Most probably the issue is a compatibility problem as Bokken 1.8 ONLY works with radare2 0.9.9 and you are using radare2 0.10.1 :/ Next Bokken release will work with the latest radare2 version.

To be sure that is not a bokken problem I would need the binary you are using; can you share it or is it private?

[blshkv]

It is definitely a new output of radare2-0.10.1 (the suspected commit is radareorg/radare2#3249) since it was working fine with the previous version.

The issue is reproducible with any binary. I loaded a random /bin/more and got the same error message. Let me know if you need it (42832 bytes)

[hteso]

Great, thanks for the info!

It will be fixed in the next release. In the meantime... I'm afraid Bokken 1.8 will only work with r2 0.9.9 :/

[blshkv]

Please share a link to a patch once it's ready so I could backport it to 1.8. It might take months for you to release a new version but the patch should be trivial. Thanks a lot

[hteso]

lol

Hopefully it will not be months, but I'll share the patch :)

I am getting the same issue,

File "/home/platform/Temporary/tmp_packages/radare/bokken-1.8/ui/radare_core.py", line 469, in get_full_file_info
self.full_fileinfo['eps'].append(['Entry0', hex(int(line))])
ValueError: invalid literal for int() with base 10: '{"vaddr":756,"paddr":757,"baddr":0,"laddr":0,"type":"program"}'

is this issue fixed and merged already? Will it be possible to get the patch

[Stenudd]

Same here, also radare2-0.10.1, no patch?

I fixed this issue with the following hack to ui/radare_core.py (for those who want to use it until a real fix is included). Basically the issue stems from the radare command iej output format being changed to the string representation of a python dictionary inside a list, i.e. [{"vaddr":4195392,"paddr":1088,"baddr":4194304,"laddr":0,"type":"program"}].

This snippet hacks the parser to use the new format.

I hate to be right but it's been 4 months and counting. Please fix it.
