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, Guru Kathiresan http://wxdsgn.sf.net

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 : Debug Formats in File: Type Size Address FilePtr Charactr TimeData Version CODEVIEW 0x00005EBC 0x0000E01C 0x00009E20 0x00000000 0x00000000 0.00 UNKNOWN/BORLAND 0x56430001 0x00000002 0x00000010 0x00000000 0x3930424E 23184.00 Unknown 0x6F432073 0x6C69706D 0x6D5C7265 0x00000023 0x6769441E 29801.27745 Unknown 0x00000002 0x00000034 0x000000CC 0x2E6E6961 0x006A626F 0.01 Unknown 0x56430001 0x00000002 0x00000100 0x6E6F6308 0x72617473 116.00 Unknown 0x56430000 0x63786508 0x736C7470 0x00000012 0x72705F07 28265.26228 CODEVIEW 0x00000114 0x000000D8 0x73686506 0x00000074 0x00010000 1.22083 ---- EXCEPTION: Debug Directory is corrupted.

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. You can find information about the wx-DevC++ IDE support for DMC at Once again thanks for the best compiler for win32. -regards, Guru Kathiresan "Walter Bright" <newshound digitalmars.com> wrote in message news:eor870$2p5o$1 digitaldaemon.com...Guru Kathiresan wrote:Hi Walter, Thanks for your reply.

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. -Guru Kathiresan "Lazyman" <mail mail.com> wrote in message news:eqcm11$2sk1$1 digitaldaemon.com...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.
