Re: [cdt-dev] One more question about Managed builder

Alex,
I don't think any of the existing option
types will output the line you are looking for. The list option probably
comes the closest, since it will always append a specified prefix to each
element it contains. That said, it seems as though you want a pre-prefix,
like -B<static|dynamic>, followed by the contents of the list. The
string option now allows you to specify 

Could you live with the prefix for each
item being -Bstatic -l, so that the output would be -Bstatic -llib1 -Bstatic
-llib2 ... -Bdynamic -llibN ...? If so, then a list control will work for
you.

We could add a custom option type that
a toolchain implementer could define, but before we take that route, I
want to make sure there is no other way to solve the problem.  As
a design principle, I do not want to see an explosion of option types to
handle every possible output case. It will make it hard to support the
build model going forward and there is a UI component to consider as well.
Currently, the UI builds itself based on the option description. String
options are displayed in an entry field, list options in a ListControl,
and so on. If we do introduce a custom option, then the implementer of
that option is going to have to supply the UI element (FieldEditor) that
represents the contents in the option graphically.

I could live with that with some reservations,
not the least of which is that we surrender some control over the UI look-and-feel
to the implementer of the custom option. Of course, this type of option
is likely to appear only in a commercial product so the implementer will
have a strong incentive to test properly. My other concern is that it forces
the implementer to write Java code, but again, only advanced users would
take advantage of this and you can (theoretically) implement a toolchain
without using a custom option.

Subject	[cdt-dev] One more question about Managed builder

I'm just looking for the method how to define  such
an option as this 
one for an import libraries list (see ld) :

-Bstatic -llib1 -llib2 ... -Bdynamic -llibN ... -Bstatic ...
I cannot imajine anything but simple 'string' option, which is not very
convinient.
If I don't miss something, I think this is one more argument for 
existing of custom option categories.
