digitalmars.D.debugger - Debugging D in windows

Hi,

I am trying to debug in windows. So far I am trying to use windbg 
like described here: http://dlang.org/windbg.html

However, in windbg when using "g _Dmain" I get an error message: 
"No Debuggee specified". Can anybody tell me what I am missing 
here? I could not find anything online and I can not find any 
option to specify a debugger.

If you know about better ways to debug in windows, please let me 
know.

Forget the version of windbg that comes with dmd. It must be one of 
Walter's nastier jokes.

If you build an executable with -m64 or -m32mscoff and -g you'll get MS 
compatible debug information in a PDB file. This works with most 
debuggers like Visual Studio, more recent versions of windbg and others. 
Use option -gc to get slightly changed debug info that works better with 
the debugger as they assume to be debugging C++.

If you need to build with -m32, the resulting debug info is some ancient 
CodeView format. This can converted by cv2pdb 
(https://github.com/rainers/cv2pdb) to a PDB file or debugged directly 
by mago (http://dsource.org/projects/mago_debugger). These tools are 
also part of the Visual D installation 
(http://rainers.github.io/visuald/visuald/StartPage.html).

Ok, I have tried your suggestions. And I also followed these 
instructions: http://dlang.org/dmd-windows.html#environment


I can't get passed this error:
LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'
--- errorlevel 1104

I have also tried to change the environment variables to:
LIB=C:\dmd2\lib;\dm\lib;C:\Program Files (x86)\Microsoft Visual 
Studio 10.0\VC\lib\amd64

so that a path to the 'LIBCMT.lib' is included.

I still seam to be missing something, but I can't figure out 
what. Can you give me one more hint?

I still can't get past this error. It might be worth mentioning 
that the problem only occurs when building for 64bit with the 
-m64 flag. Is this a known issue? Does D have problems with 64bit 
on windows?

The 64-bit version uses the linker and the runtime of the Visual C 
installation.

Check the [Environment64] section in sc.ini in the dmd2\windows\bin 
folder: it should set the LIB environment variable to the library folder 
of your Visual C installation. The dmd installer usually does this 
automatically, but might have failed for some reason or you have opted 
out of detecting it. In the latter case you should open the "VS x64 
Native Tools Command Prompt" to invoke dmd.

Awesome!

I just downloaded the zip file and adjusted some environment 
variables manually. I removed it again and used the installer 
instead. The sc.ini file now shows all the correct path and 
everything works as expected.

Thanks for taking the time to answer!

I was having the same problem and I solved it simply by 
uninstalling Visual Studio.
