MINGW32 usage #61

Closed atversky closed 4 years ago

atversky commented 4 years ago

Any advise on usage on MINGW32 produced exe? Used in follow way: cv2pdb Orig.exe New.exe New.pdb

Getting error: cannot add line number info to module New.pdb is created - cannot validate if correct New.exe - is not present

rainers commented 4 years ago

The error message indicates that the conversion process is aborted during line number emission, with the MS pdb writer rejecting some information. The resulting pdb is unlikely to be useful. Maybe the exe has some broken information or it uses some newer unsupported DWARF extensions.

If you can provide an example binary I might be able to figure out more.

Loaded ZIPPED exe into GDrive shared folder (download .zip_; rename to .zip, and extract exe): https://drive.google.com/drive/folders/1o8cv0pGx-SiBMzj_Jxvnux1ss2o_fzxh?usp=sharing

Sorry, but it seems the folder is empty.

You should login with you Google credentials. Where to upload the file? - it is 72MB.

Forked your repository. Pushed exe to Github. Try download from this location: https://github.com/atversky/cv2pdb/blob/master/test/artifacts/suricata.exe

As suspected the file uses DWARF4 line number infos. I have pushed a version that succeeds translating the debug info. Please give it a try.

Confirm, resolved. Thanks!
