this is probably a frequent source of trouble, but i really need some help on this and you all seem to be the experts. i've been trying to build a dreamcast/sh4 toolchain and so far i'm stuck on compiling glibc. i've been using several guides as references and found bill gatliff's "An introduction to embedded linux" the best so far. First i downloaded the latest nightly cvs of binutils (binutils-020814.tar.bz2) and cross-compiled it for the SH4 architecture (no patches applied). then i downloaded the latest stable gcc release 3.2 (pretty recent) and finally got it to cross-compile. now i started trying to cross-compile glibc 2.2.5 (without patches, and maybe once with them), but it seemed to be giving me too much of a hard time, and because of my deadline i downloaded glibc 2.2.4 and the patch for it. patch installed, i played around with the configure options, and had errors each time i tried to make it. finally, i thought it would be finished, but it seems to have had a strange error. here's the final snippet of the compilation:

Others might be able to give you specific advice about your errors (I am not an expert). But you *do* need to use a patched compiler, toolchain and glibc to build your kernel. The patches are available from ftp.m17n.org - in ftp://ftp.m17n.org/pub/super-h/testing/ IIRC - you will see what version they are patched against there. You can always ask for advice on the irc channel too: #linuxdc at irc.openprojects.net. Keep us informed of any progress. A. |

All 3.x versions of GCC can be cross-compiled without patches, but they won't compile much correctly and binutils won't generate working shared executables. Just grab 3.0.4 + patches and you should be fine. Make sure your binutils and glibc are patched as well. DO NOT USE STOCK TOOLS FOR SUPERH -- EVER. Even MIPS targets usually require an outside, patched toolchain. Thanks, M. R. |
