[cdt-dev] Launch configurations coupled with specific toolchains

[Corey Ashford <cjashfor@xxxxxxxxxxxxxxxxxx>]

Hello,

A group of us here at the IBM Linux Technology Center are developing a 
bundling of Eclipse + other plug-ins + the CDT, including a custom CDT 
toolchain which superclasses the GNU toolchain, but uses gcc, etc in a 
different path.

The CDT documentation seems to imply that there's a way to connect a 
custom debugger path to a toolchain; Klaus Kiwi found this reference at

http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_new_proj_wiz_toolchain.htm

"A toolchain is a set of tools (such as a compiler, linker, and 
assembler) intended to build your project. Additional tools, such as a 
debugger, can be associated with a toolchain. There can be several 
toolchains available, depending on the compilers installed on your system."

However, when I look in the CDT source code and use the UI, I haven't 
found any such connection.  The code for the DSF GDB debugger, for 
example, just uses the default debugger command from the 
DEBUGGER_DEBUG_NAME_DEFAULT constant defined in the 
org.eclipse.cdt.dsf.gdb.IGDBLaunchConfigurationConstants package.

Also, I haven't found anything linking a toolchain to a launch 
configuration.  Is there any communication between these objects? Are we 
missing something here?

Thanks for your consideration,

- Corey
