CDT sets solib-search-path for gdb and it is enough to find shared libraries Marc Khouzam wrote: _____ Subject: Date: Thu, 13 Mar 2008 11:06:22 -0400 Hi Tobias, thanks for trying the remote launch. I will delivery some UI changes to clean it up some more, but at least it now works. The CDT seems to use -environment-directory so I'll figure out how it works and add it to ours. But I don't understand how come the CDT does not use set sysroot, since you seem to need it. How does the CDT find shared libraries when doing remote debugging?

In my debug session I have checked the "stop at main" and got the ouput below in the gdb debug console. Regarding the -gdb-set and -environment-directory commands, what strategy should we use here? In my code, I am setting the -environment-directory to the source directories defined in the project, and if none are found it is set to the project root. Also, I have extended the GUI for CDT debug mi (the GDBSolibBlock.java and IMILaunchConfigurationConstants) and included a text field for defining the sysroot path. Not sure that that is the best place for it though.

I have tested it on linux (host and target). Some cleanup is still needed, but I was able to do a full debug session. To use it, create a new launch from the ?Remote C/C++ Application (Experimental - DSF) Tobias, maybe you can try it on Windows? Note that I didn't use -file-symbol-file -environment-directory -gdb-set sysroot since I didn't need them on Linux. Once you try it on Windows, I can add whatever is necessary.
