I'm trying to build a cross compiler for z/tpf using gcc 4.1.2 The configure seems to complete ok, but the make dies with "no rule to make ...tpf-as, needed by stamp-as" (tpf- is the defined program-prefix). I'm new to this so I'm rather in the dark about what to do next. I've gone over my work, and checked the generated makefile but can't find the instruction to build stamp-as, nor its dependency on tpf-as. Are there any debug options that would help me to understand what's going on here and where those commands are being generated? ian ... Ian S.
