E.g. gcc-cross, >> gcc-cross-canadian, gcc-cross-initial, gcc-cross-intermediate, gcc- >> crosssdk, gcc-crosssdk-initial, gcc-crosssdk-intermediate, gcc-runtime, >> etc. gcc-cross-initial - This is the initial compiler needed to bootstrap the toolchain to build software on the host for the target. (This is a 'native' package.) gcc-cross-intermediate - This is the second stage of the bootstrap process to build software on the host for the target. (This is a 'native' package.) gcc-cross - this is the the final stage of the bootstrap process, and results in the cross compiler to build software on the host for the target. (This is a 'native' package.) If you are replacing the cross compiler toolchain with a custom version, this is what you must replace. gcc-runtime - these are the runtime libraries, but from the toolchain bootstrapping process. This results in a 'target' binary. gcc-crosssdk-initial/intermediate - stage 1 and 2 of the a cross compiler to build from the 'host' to the 'sdk'. Often the SDK is not the same target as the host. (This is a 'native' binary.) gcc-crosssdk - this the final stage of the SDK compiler. Again, this is to build on the host, for the sdk. This is a 'native' binary. gcc-cross-canadian - This is the compiler included with the SDK to build on the SDK machine creating software for the target. This is an 'nativesdk' package. >> Is there any document for those description? Not that I know of.. It's one of those things that you kind of need to know in order to work with it.
