C++ Builder XE2 - is it possible to debug vcl data library?

Question

I am using method TParams::ParamByName when working with SQL database. Source code of this method is placed in directory c:\Program Files\Embarcadero\RAD Studio\9.0\source\data in file Data.DB.pas. Is it possible to debug source code of this unit? Currently I am able to debug data unit only using asembler window (without viewing commands defined in higher programming laguages). VCL is statically linked to the program.

Answer 1

Go into the Project Options.

There is no need to set Use debug .dcus under Delphi Compiler > Compiling if your projects contains only C++ & C files (see Remy Lebeau answer).

Disable Link with Dynamic RTL under C++ Linker.

Disable Link with Runtime Packages under Packages > Runtime Packages.

If your project (lets name it Project1) was upgraded from older versions of development environment (C++ Builder XE and older), delete parameter Directories & Conditionals -> Library Path from all nodes (All Configurations, All Configuration - 32-bit Windows Platform, Debug Configuration, ...) except paths specific for this particular project. Open second instance of C++ Builder XE2. Click File -> New -> VCL Forms Application. Right click on project in Project Manager and select Options. Navigate to Directories & Conditionals -> Library path. Copy paths from all nodes to their counterparts in Project1.

Answer 2

Go into the Project Options.

Enable Use debug .dcus under Delphi Compiler > Compiling.

Disable Link with Dynamic RTL under C++ Linker.

Disable Link with Runtime Packages under Packages > Runtime Packages.

You will then be able to step into the VCL/RTL source code.
