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.

Hello Mark,

Thanks a lot, this is very helpful for understanding the different recipes of toolchain.

Re: Difference of toolchain recipes

[Rifenbark, Scott M]

I think what I am going to do is document these in general as part of the "Terms" section in the YP Development Manual where the term "Cross-Development Toolchain" is defined.  Would putting such a high-level list in the YP documentation be unnecessary or helpful?

I think it would.  The set of compiler/toolchain elements we have is definitely 
confusing to someone new.

Difference of toolchain recipes

[Luo Zhenhua-B19537]

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. 

Is there any document for those description?


Best Regards,

Zhenhua
