RE: [cdt-dev] assignToOption for inputType element

Hi Delicia,

 

You shouldn’t be specifying multipleOfType=”true” in this case, but I don’t know if removing that will solve the problem.

Subject: [cdt-dev] assignToOption for inputType element

 

I have a situation where I need to use a custom linker script (which gets built as a pre-link step).

We do this by using the -T linker flag : cragcc a.o b.o -T <linker_script_name.ld>

 

This is the case only for special projects that use multiple processors.

After having a look at the MBS documentation, I figured, the best way to do this, would be to use the "assignToOption" field of the inputType element.

 

So what I have is:

<inputType
   assignToOption="cra.c.link.option.linkerscript"    //This option has <command="-T">
   buildVariable="LDSCRIPT"
   id="cradle.toolchain.c.linker.input3"
   multipleOfType="true"
   sources="ld">
</inputType>

 

As per the documentation, whenever a linker input of this type ($LDSCRIPT) is found, the flag "-T" should be prepended to the filename.

My makefile shows that this is exactly what happens.

 

However, my problem is that the dependencies for this step go for a toss.

$(LDSCRIPT) is the buildVariable for the pre-link step, so this should get built first - which happens if I remove the "assignToOption" from the above description.

 

Once this assignToOption is added, the prelink step doesn't happen, and it seems like the $LDSCRIPT variable does *not* even get defined (apparent from the final build step.

 

I even tried adding LDSCRIPT to the 'builder's' reservedMacroNames but that didn't help.

Is there a known bug of this type? Any other workaround I could use?

 

Thanks,

Delicia.
