Version Of Joern #3

Open initialWu opened 2 months ago

initialWu commented 2 months ago

Thanks for your work! I want to get an example of CPG, but when I tried to use your function:

cpg_file = process.joern_parse(joern_cli_dir, input_path, output_path, cpg_fname)
json_files = process.joern_create(joern_cli_dir, output_path, json_out, ['test_0.bin'])

I got the following output: image

Then I used your process command cpg.runScript in function joern_create of utils/process/cpg_generator.py in joern terminal, but I got this error: image

So I don't think I have the same version of Joern installed as yours. Can you please tell me which version you are using? The Joern I installed is Version: 2.0.357. The Joern document gives instruction of implementing scripts like This. So I tried to modify your graph-for-funcs.sc scripts, and added a cpgFile parameter(path of bin file obtained by joern-parse) and an importCpg call(following Joern Document) like :

@main def main(cpgFile: String): Json = {
  importCpg(cpgFile)
  GraphForFuncsResult(

But then I got more errors. image Could you please give me some help? Thanks.

@initialWu Hello, When I used cpg.runScript, I get the same error. The Joern I installed is Version: 2.0.401 I'd like to know if you've solved this problem, and I'd be very grateful if you could give me a reply.

The new version of Joern no longer supports cpg.runScript. I resolved this issue by directly running joern-cli with the --script parameter, following the methods described in Joern’s documentation. The provided scripts in the repository might require modifications in new version.

I've got the same error after running the script, it might be caused by the absence of io.circe in scala3. Have you resolved the issue?

I have resolved the issue by rewriting the script and rebuilding the joern, the problem is caused by lacking certain scala packages
