I’m using Eclipse plugin, but the same error there is using command line (env.bat is just done), I’m not able to complete the build process. I’m using the basic example generated automatically by Eclipse, only choose a diffrent processor, no more.  
The CDT under eclipse use the following command line

`dld -tPPC555EN:windiss -o PPC_Test.out ../bubble.dld ./bubble.o ./crt0.o ./swap.o`

and the error is

```auto

15:15:39 ****Incremental Build of configuration Debug for project PPC_Test****

make all

Building target: PPC_Test.out

Invoking: Diab C Linker
