RE: [jamboost] Adding a post link stage

BTW Have you seen the typo on this page : (look for "Dowloading")

http://boost.sourceforge.net/boost-build2/

Thanks for all your help in that last email, it helped me understand what
was going on a lot, and no i hadn't seen the extending doc before. (the link
at the top right of the contents perhaps might have a bit better
description). 

Incidentally I do like the look of the new V2 docs, (front page could do
with being run through a spell checker)

But I'm still struggling a bit, so far I have :

gccmt.jam : (which is exactly the same as gcc.jam but the following lines
added)

type.register LDR : ldr : : main ;

type.set-generated-target-suffix LDR : <toolset>gccmt : ldr ;
type.set-generated-target-suffix EXE : <toolset>gccmt : preelf ;

generators.register-composing gccmt.ldlk : EXE : LDR : <toolset>gccmt ;

actions ldlk
{
$(NAME:E=ldlk) -g -Tldlk.img
}

Now if I understand correctly, the type.register creates a rule something
like this :

rule ldr ( ... )

so in my Jamfile, I need only do the following :

ldr test : test.c ;

which will ultimately produce the following transformations :

test.c -> gcc -> test.o
test.o -> gcc -> test.preelf
test.preelf -> ldlk -> test.ldr

Does what I've done seem correct?

If so, the make fails with the following output :

.../build\targets.jam:1089: in construct from module object(typed-target)@1
error: unable to construct ./test
.../build\targets.jam:917: in object(typed-target)@1.generate from module
object(typed-target)@1
.../build\targets.jam:509: in generate-really from module

.../build\targets.jam:482: in object(main-target)@1.generate from module
object(main-target)@1
.../build\targets.jam:178: in object(project-target)@1.generate from module
object(project-target)@1
...\build-system.jam:151: in load from module build-system
.../kernel\modules.jam:259: in import from module modules
.../kernel/bootstrap.jam:120: in boost-build from module
...\boost-build.jam:1: in module scope from module

I don't quite know what to do now. The build is failing at code I've not
editted, presumably through the code generation from type.register. But I'm
at a loss of what to try next.

Thanks again for your help
