NullPointerException: langDescription() is null

Open SomeOtherDev opened this issue 1 year ago • 3 comments

Hi,

I could be running this incorrectly but I'm really not sure at this point given the error below:

anon@anon:~/QtRE$ ./run.sh -p QtRE-1.0.0.jar -c test.json --analyze-connect --analyze-meta

  "EMULATION_TIMEOUT": 30,

}

I downloaded the linked copy of ghidra 9.2.2, ran the buildGhidraJar script, and copied the resulting ghidra jar file into QtRE/lib. QtRE was compiled by git cloning the repo and running mvn package.

Is this a bug?

Hi @SomeOtherDev. Could you replace the LANGUAGE_NAME field's value with x86:LE:64:default? This attribute is defined in https://github.com/NationalSecurityAgency/ghidra/blob/master/Ghidra/Features/Base/src/main/java/ghidra/program/database/ProgramBuilder.java#L64

Thank you @onehouwong , that seems to have resolved that error. I must have forgotten to add the default when I was making the config file.

I received a different lengthy error, but I suspect this isn't a bug of this project, but something to do with my ghidra configuration.

I'll post the error anyway but please feel free to close if you feel it's not relevant. Thanks again for resolving my issue
