Re: Does ICAT understand watcom .sym files?

Show all headers | View raw

Have you placed the sym file into the same directoy on the HOST (where 
ICAT executes) as the driver binary ? And have you modified the ICAT cmd 
file to point to that directory ?

Yes, I seem to remember that with the approach above, I had limited 
debugging capability (with the wat2map.cmd and mapsym.exe approach).

Needless to say that sym file support is very restricted. It only knows 
public symbol names, it has no clue of type definitions and no clue of 
stack variables.
That also means that you should NOT mark any variables or routines as 
"static" if you want to see their symbol names. "static" will prevent 
that symbol name from showing up in the map file and consequently it 
will also be missing from the symbol file (check your map file).


What I have done in the past is write code that compiles with cl.exe (+ 
some assembler code) or icc.exe (VAC) and compile+link with Codeview / 
HLL debug info. That'll allow to do full source code debugging over ICAT.
Then, when everything works, you can switch over to Watcom.
