The CXX problem is not solved that way:
type.register CXX : cxx : CPP ;
error: Attempting to specify type for suffix "cxx"
error: Old type CPP, New type CXX

The header generation still does not work. I have a lib target and
inside a dummy.err. From this a dummyerrors.h should be generated. The
documentation (link) is working with a lib AND a exe target using this
specifier ...

I have:

lib dummy
    : dummyerrors.err
    : <link>static

BJam is not yelling but also it is not doing the job...
Also it is not very nice to write dummyerrors.err two times as here...
Can somebody help, please?

Again about Example: 1-to-1 generator.
When trying to use this like here...

type.register ERR : err ;
generators.register-standard err.convert : ERR : H ;

... then the output is "...found 1 target..." and the defined action 
will be not executed.
Changing it to...

generators.register-standard err.convert : ERR : CPP ;

the action will be called. How do I use this for headers?



My script (inside of actions) does accept two parameters (input and output);
so I use $(>) and $(<). How can I access part of the file (path, 
filename, extension)?
Why? The script could do it by I intent to do something like 
(filename.ext -> filename) But here I get!


E. g.

$(1:P) for parent directory
$(1:BS) for filename + extension

What do I have to do for using CXX instead of CPP. Registering as a type
like above didn't work.

Try this:

type.register CXX : cxx : CPP ;

The last parameter is optional and denotes 'base-type'.
Although I think that boost build does this somewhere for you.
