I was not able to build a multi-lib ARM Linux EABI toolchain so far. Looking at the code in gcc, it seems that all multi-lib definitions are nuked-out for arm*-*-linux-*gnueabi tupples. OTOH, the multi-lib _code_ in crosstool-NG works, as I was able to build a Sparc multi-lib toolchain (but it required a few unrelated Leon patches to gcc, so it is not available as a sample). Also, Per has submitted a working bare-metal multi-lib ARM EABI sample yesterday, which means that the multi-lib support (in crosstooll-NG) if operational. Basically, it looks like the culprit here is, at least partially, in the gcc code. It can also be the case that we incorrectly drive the gcc ./configure and/or make, of course. This is why I announced it a 'initial support for multi-lib'. The code path is known to (rather more than less) work. Yes, I could have been more explicit by stating that there were yet some issues and restrictions. This means there are still some changes to do to make it ubiquitous, and that will have to be done is the release cycle(s) to come. Although I will be working on this on my side, it's not a top-priority for me. So: patches and .config welcome! ;-) Regards, Yann E.
