Plugin debugging basics

[Anonymous]

Hi:-)
Pretty new to debugging plugins. I am debugging a maya plugin from way back 2004. I know it is working, because I have compiled and used it. The point is that I want to analyze it. I have loaded the plugin in Maya and attached maya.exe in the visual studio debugging environment. I am loading symbols from the Microsoft Symbol servers. What I am not quite sure about are all the output statements I get when I attach.....

......... It goes on like that, then finishes:

Is this normal behaviour, or is there something wrong here ? I can see that the PDB(s) is/are not being found or loaded for all the Maya dll's but is that the way it is supposed to be ?
When I run the plugin I get a lot of these:
First-chance exception at 0x7710c83b (kernel32.dll) in maya.exe: Microsoft C++ exception: FNPNS::TSM::CDoesNotExistException at memory location 0x0162f334..

Can someone please enlighten me.....?

The same problem here.

Win7x64Sp1 + Maya 2015 + VisualStudio2013

Can't find OpenMayaUI.pdb

That is correct output, Autodesk won't ship the pdb's (symbol files) for Maya as its commercial software. Providing you have the pdb's for the plugin you want to debug (I'm assuming that is TestMaya.mll and it says Symbols Loaded 🙂 ) you will have enough information to step through the plugin code in a debugger. Without the pdb's you can still attach and debug but you'll be looking at the assembly code. Just to be clear you won't be able to step into the Maya API calls but you will see variable states in the watch window etc.
