Display compatible toolchains only | When selected, it shows a list of toochains that are only compatible with the current configuration. When this option is not selected, it shows a list of all toolchains known to the Eclipse CDT. A Toolchain is compatible if it can run on given platform. .
Current toolchain | Indicates the toolchain to use with the current configuration. 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.
Current builder | Indicates the builder used to build the selected configuration. A builder refers to an external make utility, such as GNU make, that the Eclipse CDT uses (and relies on) to build a project. The CDT can generate makefiles automatically when you create a Make C or C++ project, or you have the option of creating a C or C++ Make project where you provide the makefile yourself.
Used tools | Shows a list of tools currently included for the selected toolchain. You can click Select Tools to modify this list.
Select Tools | Opens the Select Tools dialog that lets you add or remove tools from the list of tools for the selected toolchain.
