I have a problem with setting Browsing Path in Delphi 2009:
When I install a new component, I add DCU path to Delphi's Library Path, and source path to Delphi's Browsing Path. The application compiles fine, but holding Ctrl and clicking on any of the unit names for that component does not open the source file!
It seems the only way to make it work is to add source path to Library Path, but this means I have to compile all the units belonging to third-party components every time I build my project!
This problem does not exist for Delphi's standard units, or even JCL and JVCL units which are installed by JCL\JVCL installer, and their source paths are added to Browsing Path.
Is this a bug, or it is me doing something wrong?
Regards
I was struggling with this problem for a long time. Changing REFERENCEINFO in package settings from "none" to "definitions only" did the trick. Hope this will help you also.
Are any of these units listed in the .dpr ? Units there with a wrong path can cause pretty funky behaviour.
Setting "Symbol Reference Info" to "Reference Info" does indeed fix the issue with Browsing Path.
But at least for Delphi XE the change has to be made in "Build Configuration -> Base" for it to work.
I would ensure the dcu's were compiled with debugging turned on. If this is a third party component and the source is provided with it this is usually the case but not always.
