Hi there,
If IDA Pro does not identify any functions, BinExport will not have any entry points to start from and hence will also not find any. That the downstream BinDiff results are not useful in this case is to be expected.
I'm curious though, as to why IDA does not find any functions in a stripped binary. Didn't you complete the auto-analysis using autowait
or similar?
If you want to prevent BinDiff from using symbol information, you need to disable the respective algorithm in the bindiff.xml
config file. In /etc/opt/bindiff.xml
or in your local ~/.bindiff/bindiff.xml
, comment out the function: name hash matching
step under the function-matching
element.
Note that this should rarely be necessary, as BinDiff will only use "real" names, i.e. those that belong to either imported functions (without an actual body in the current binary) or user-supplied ones. It will ignore auto-generated names from the disassemblers ("sub_xxxxx
").

Thank you for the suggestions.
I do have an autoWait()
call in the .idc script for IDA, to wait for auto-analysis to finish for the stripped binary.
Using BinDiff after disabling the function: name hash matching
algorithm in the bindiff.xml
config file looks like a good solution for my case as I have real function names in the binaries before stripping.
