Subject: Difference of toolchain recipes
It is a bit confused for the different recipes of toolchian, can somebody
help to explain what's the difference for those recipes? 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. It likely should be documented somewhere officially.
