Title: How to set "Symbol search path" for CB 10.05 with windbg
Post by: pinfutech on September 15, 2012, 08:58:23 am

as described below, the default path is the project path [F:\MyTemp\HelloWorld],
how can I set the symbol search path to the executable path [F:\MyTemp\HelloWorld\bin\Debug]
Building to ensure sources are up-to-date
Build succeeded
Selecting target:
Debug
Adding source dir: F:\MyTemp\HelloWorld\
Adding source dir: F:\MyTemp\HelloWorld\

1. Read the help of CDB for the correct command (CB doesn't use windbg)
2. Install a nightly build (this is optional, but recommended)
3. Put the command in the initial commands of the debugger

I'm using CB for first time, I use Visual Studio series for a long time.

What I confused is the hint message followed:
*** WARNING: Unable to verify checksum for HelloWorld.exe
now I know what happened.
No breakpoint, no the warning message, but if breakpoint set, the warning message is shown.
This is not errno, but is confusing.

cdb is a executable file in windbg package, CB call it silently.
As a newbie, I didn't know cdb and windbg, just download windbg package follow some guide by google.

Thanks for the reply.

Can I ask you why are you trying to use visual c++ with c::b?
If it is not a project requirement you'll have better success with mingw gcc + gdb,
because they work better inside c::b, especially the debugger as cdb is not meant for integration in other IDEs.
This is why we have pretty limited support for debugging vc++ executables.

Also if you want to use cdb or the debugger as a whole upgrading to a nightly build is highly recommended as there are many improvements and bug fixes.

I develop cross-platform programs for Windows and Linux.
Not use mingw + gcc + gdb, just for performance consideration, and the other one, is I'm used to use Visual Studio 2003+.
Encapsulating lower level APIs, debug in Visual Studio IDE, and not so much code need edit under Linux, I use gcc+gdb under Linux.
Use CB, because some hardware provide VC6-based SDK and source, and I want to use a light-weight IDE for some develop machine.
