When I start dbxtool from the command line via dbxtool "my_prog my_args", the GUI launches and a popup appears saying
dbx: 32-bit dbx can't debug 64-bit app
I installed developer studio 12.6 from the tar.bz2 file on Linux RHEL7 and added
OracleDeveloperStudio12.6-linux-x86-bin/developerstudio12.6/bin
to my path.
Note that dbx -c "runargs my_args" my_prog starts just fine.
I read that the workaround was to stop the originally launched dbx and reload the program which does indeed work but that is rather inconvenient and I would really like to get this working out of the box. Can someone help me on this? (Editing the startup scripts etc. would not be a problem for me)
