That's what I originally tried -- passing in both --disable-multiarch and --disable-multilib -- but when I include --disable-multiarch, then I'm back to that same install error I was getting before. I just tried it again, with the later eglibc (2.15), and it still errors out (i.e., libgcc isn't included in the build).

You just want not to use " --enable-multiarch".

On the other hand, disabling multilib didn't accomplish what I wanted. What I want is for things to be where they used to be, with regard to /lib, /usr/lib, /usr/include, and include/C++ -- I don't want that extra arm-linux-gnueabi subdir under those. Granted, I can re-organize things once I've got the toolchain built, but it would be nice not to have to go through all that, since it's a bit of a pain to do (it's not just moving files, but re-doing symlinks as well). That's what I hoped --disable-multilib would do -- keep things simple and not create those extra subdirs. Is there no way now to not have that happen?

Thanks,
Diane

I don't build eglibc -- I use a prebuilt one. But that does look to have been the issue. The one I used before was 2.12.1, so I tried a later one (2.15) and things worked.

Thanks very much,
Diane

How do you build your eglibc/glibc?

Can you share your gcc config for me to reproduce it?

Thanks!
