Debugging issues with C/C++

Post by l.cedric » Thu Oct 31, 2019 10:29 am

Hello,
after trying a lot of suffs from VMS-IDE, the last one i tried is the Debugger.
  1. I've succeeded in a simple (C) case, but not at my first try : After reading carrefully this post "Debugging issues with Fortran", because the symptoms are similar to my C/C++ code, i found the reason and a workaround (VMS-IDE bug ?)
  2. But not for a more complicated one (which is one of our production code), still an issue :
    • The debugger starts at the wrong line, and this for each steps until the end :-(
    • But nevertheless the code seems to be executed according to the debug console
Details about these tries :
  1. The simple one :
    • As you can see below in the 1st screenshoot, it successfully runs our com file, which compiles and links the code into the exe and debug files, and the command file copies those to the correct directory (mantis.build.DEBUGsansMMS, the last part must be the same as the label)
      simpleOutputRunKO&OK.png
    • This all seems to work correctly. I go to run the debugger :
      • Remark : it comes up with warnings that the .LIS file doesn't find for other source files
        • It seems to be normal for our current settings as few executables are in this same project (due to our old folder organisation), and VMS-IDE search a .LIS with each "source" (in project settings) file it finds.
        • I'll search later if it's possible, thanks to some filters's settings (or ?), to select only one executable (& its .LIS) among other. Because we usually need to debug just 1 executable, not the whole …
    • But the "annoying" issue is there :
      • As you can see above in the 2nd screeshoot, it seems to start at the end !? Nevertheless, I can step through my application until the end with good results in the debug console (but the cursor stays at the end) !?!?
      • So at its very end, this post "Debugging issues with Fortran" gave me a clue : "it didn't like my /list qualifier at the end of that include".
        • So as i didn't have this type of syntax in my C/C++ code, so i didn't pinpoint this clue right away …
          • Nevertheless, In case of, i took a look into the .LIS and … I see the whole includes expanded !!!
          • Moreover this page about the Auto-generated MMS show a very simple build option (just ~ /deb/noop/), which was not my case, due to our old production compilation options, I also simplified by this one "/SHOW=(BRIEF,INCLUDE)" (at least) which breaks the VMS-IDE debugger
        • If you remove this from the compilation everythings rocks ! The proof after few steps in the 3rd screenshoot above :-)
  2. Now the more complicated one … (still C langage) :-(
    • Now as I have the basis to work with the debugger, I try one of our production code (executable) with, of course, the help of our MMS to deal with the few OBJ and complicated build options needed.
    • So without these few other compilation options (i just managed to remove the previous /SHOW … which is at least one which breaks VMS-IDE), I can't build our current production code !
    • The result in brief which is not exactly like the previous one :
      • It starts not at the end, but at the wrong line ! :-(
      • Nevertheless, I can step through my application until the end with good results in the debug console and the cursor moves fowards (but always at the wrong line) but it is very tricky to follow the code … :?

    Here's the whole output's options used (because above it is truncated) :

    As i didn't find how to attach a zip file in this post, if needed please mail me to get the full lists.zip, nevertheless here's an extract of the main .LIS file and the whole .MAP (noticed the FF escape sequence i have to add to mimic the real file ... I don't know if it could be an issue for VMS-IDE ?)

  3. Remark : i've also tried with a C++ one, and ~ the same type of issue :-(
Anyone have any ideas on what to do ? Thanks for any help !

Re: Debugging issues with C/C++

I answered to myself, because after few others tries I've just found the root cause :
  • In the previous post I've noticed few FF escape sequence in the .LIS ... but in fact they came from our source files :shock: !!! Indeed, our old code (~25 years old) is full of these stuff due to some VMS old editors ... not as friendly as VSCode, and so helped us to navigate quickly in the source files.
    sourceFF.png
    sourceFF.png (8.57 KiB) Viewed 102 times
    (not displayed by default in VScode)
  • When i count them ... 9 FF ... before the main function ... which is exactly the number of shifted lines in debugger execution ! :idea: So i remove them to my source file to test et Voila !

So to summarize the whole thing :
  1. The simple one : VMS-IDE debugger does not yet support the compilation option /SHOW=... (see above)
  2. The more complicated one : VMS-IDE debugger does not yet support FF escape sequence in the source file
Just a little confirmation : Is it the right place to post VMS-IDE issues for the developers :?:
Thank you in advance VSI :)

Thanks for a good investigation!
There is a big issue to find a right line in source by information provided by listing.
We cannot just compare each line from listing with each line in source. But, of course, we have to improve our algorithm...
PS: about ZIP - you can upload it on some cloud and put a link here.

Thanks Sergey for the confirmation of these issues.
And if needed, here's the lists.zip :
