c++ - Commandline option for windbg/cdb

↑ ↓ ← "Guru Kathiresan" <gururamnath -----yahoo-------.com> writes:
Hello,
I'm trying to use windbg/cdb to debug a small "hello world" program but so 
far the debugger is not able to put a breakpoint in the requested line.
Currently I'm using -g and -D to compile the code.
Can anyone please let me know what other commandline options we need to pass 
?

Following are the cmdline I'm using to compile the executable :

dmc.exe /c main.cpp -oDMC/main.obj -A99 -D -g
link.exe /NOLOGO /SILENT /NOI /DELEXECUTABLE /EXETYPE:NT /su:windows:4.0 
DMC\main.obj , DMC\consoltest.exe, ,,,

Thanks,

Need to pass /CO to the linker.

Hi Walter,
Thanks for your reply. I am able to generate the debug information in the 
exe (after some struggle, as my  path variable had + sign) but it is not 
recognizable by the cdb. I'm using the July 2006 release of cdb (6.6.7.5).



When I view the executable content in a PE viewer  ( 
http://www.smidgeonsoft.prohosting.com/pebrowse-pro-file-viewer.html ) I can 
see the CodeView section. When I use another PE view I get the following 
info :

Currently my modified command line looks like this :

Try using windbg.exe that comes with dmd.

Hi Walter,

It seems the windbg provided with dmd is pretty old. Is there any chance to 
make the debug info recognized by the latest windbg/cdb ? Or If you have the 
cmd line equivalent of winddbg (cdb) that supports CV 4 format, please let 
me know where I can get it.



The main reason for asking this is that we are adding support to Digital 
Mars C++ in our wxWidgets IDE wx-DevC++ and so far we are able to make the 
IDE work seamlessly with the build system (currently out of the box a 
wxWidgets app can be compiled with DMC without any manual configuration) but 
the debugging part is still not working. Currently we have added the ability 
to debug VC++ built executables by interacting with cdb but we are not able 
to use it for debugging dmc produced executables.



If there is chance to either debug the dmc exes with cdb or gdb (we do 
support it in our IDE), I'm sure thousands of users will greatly benefit by 
the ultrafast dmc. With our plans to support wxD Form designer, even the D 
users will also benefit from this.

Once again thanks for the best compiler for win32.

It's a lot of work.

Walter is being asked for ages to modify symbol output, but he either refuses
to talk about it or says that it's up to OPTLINK
which is not his own property. I think we wait until he retires and the DMC
goes open source.

I actually found that the watcom debugger can debug the code generated by 
DMC(provided you need to add the source path in the debugger). I have 
already created a prototype of the commandline version of Watcom debugger. 
We'll eventually add integrated debugging for DMC generated executable in 
wx-DevC++. I'm really excited to know atleast there is an alternative 
solution now.
