Yes, this is the version I (hopefully) use: binutils-2.21 in a "combined build" (I extracted them to the gcc-4.6.0 directory and created a symlink binutils). I got this error via the built gcc/xgcc, but I get literally the same error using my old compiler/linker (gcc-3.4.3 with GNU assembler 2.16.1, which I successfully use for my ARM thumb builds since years, so it should be ok). > If you don't care about the Thumb mode, you can skip this > problem by passing --disable-multilib when you run configure. I'm specially interested in Thumb mode code, because of the code size. (My old installation using an old linker (GNU ld version 2.16.1) which is not supporting thumb images > 4MB because too old to generate the needed stubs, as you kindly explained me citing the NEWS file: > binutils 2.19: "The ARM EABI linker will now generate stubs for > function calls to symbols that are too far away.

So you may want to consider trying > binutils 2.21. ) so I'm trying to upgrade, which seems to be more complex as it seemd to be, as usual :-) Any help appreciated! oki, Steffen
