I know the cause because i use the old remap file, but the bincat plugin seem clash with Lighthouse plugin. when two plugin is installed ,the ida will crash.

Thank you for your report.

Two questions:

• Which version of BinCAT are you running ?
• Do you have non ASCII characters in your configuration file ? For example the binary path.

[CrackerCat]

1. BinCAT version : 0.7.
2. binary path have non ASCII characters. the plugin is good ,thank you work.

[trou]

OK it's probably a pb with non ASCII chars, I'll try to fix it tomorrow.

For reference, making this work is definitely not as easy as I initially thought:

• IDA 6 returns paths in the OS's encoding (as str)
• IDA 7 returns paths in UTF-8 (as str)
• IDA's open expects a string compatible with the current system encoding
• Python 2's ConfigParser only handles ASCII strings

So lots of fun things involved...

[trou]

and of course, OCaml's Unix.openfile on Windows fails if the path is in UTF-8 because it should use whatever stuff Windows uses.

Should be fixed in 98cc155604619df3cc9ab6689f3779035952d1e5
