I do have cross-compilers around, but unfortunately the gnugo build system expects to build and run mkpat on the host system as part of the build. I think configure does support this kind of thing, but it probably needs some extra work to support it. I was able to build by just copying in the native mkpat etc manually. The section sizes from objdump are .text: 000b6a88 .rodata: 00069201 .data: 0013f0b0 .bss: 001a5f48 around 1Mb read-only and 3Mb writeable Note that these are relatively old tools (for zaurus). gcc 4.x is quite a lot better for arm. Thumb would probably make it a bit smaller, if your target supports that. But it's probably the ram size rather than the code size that's more relavant. > 2.
