Re: Specifying a debuginfo path independently of sysroot

[Ray Ruvinskiy <rruvinsk at sybase dot com>]

Hi Sami,

We save debug symbols for every build on a central server. The  
binaries that are tested (and shipped) are stripped, except for a  
gnu_debuglink. To debug issues on QA machines or customer issues, we  
find it convenient to simply create a symbolic .debug link from the  
directory where the binaries and libraries are installed to where we  
keep the symbols for the particular build we want to debug. The  
directory structure of the symbol repository does not necessarily  
match the directory structure of the location where the software was  
installed.

Thanks,

Ray
