RE: [cdt-dev] extending the toolchain

Hi Thomas,

The first part of your message looks like a bug.  Would you create a
bugzilla entry?  Please raise the priority to "major" if you would like
to see it addressed in 3.0 - the MBS has a lot of bugzillas and they
won't all get addressed in 3.0.

The second part of your question also looks like a bug, but I think we
will be addressing it in our 3.0 work.  The MBS currently has a lot of
special case code around the handling of the linker/librarian step.  I
will be posting a "Multiple Inputs & Outputs" design soon that I think
will address your problem in 3.0.  Please review it when it appears.

Subject: [cdt-dev] extending the toolchain


I extended the toolchain and added my own tool. The tool is called
properly when building a project, so this works. However, I run into
quite some trouble when the target of the makefile is build. The rule
there says that it should simply add all objects. Nothing wrong with
that, but objects generated with my tool are not recognized properly.
The problem is that my tool generates a file with a prefix (output
prefix). However, the objects pulled in the target rule do not reflect
this prefix.

If I have a source file "foo.b", my tool generates "prefix_foo.u". I.e.
that the target step tries to pull in "foo.u" which does of course not

The stuff which breaks it is in GnuMakefileGenerator. You generate a

 * Create the pattern rule in the format:
 * <relative_path>/%.<outputExtension>:

instead it should be:
 * <relative_path>/<outputPrefix>%.<outputExtension>:

So, in the file we should get something like:

OBJS := ... $(B_SRCS:$(ROOT)/%.b=prefix_%.u)

and in the file:

prefix_%.u: $(ROOT)/%.b
	@echo 'Building file: $<'

Another question: Is it possible to add a tool/compiler which generates
something which should not be linked to the target, because the compiler
does not generate any object code?

Kind regards,
