I think it is because of a problem previously handled here #149398 for binutils-2.17. I am going to attach an excerpt of ebuild.log and a provisionary patch which worked for my special case (host: armeb-softfloat-linux-uclibc), but probably would mess up the ebuild in general. I am currently testing another patch which is not that invasive, but truth to be told: I am not really good at patching configure-scripts, so someone with more experience should take a look at it (the non-invasive one). PS: It's my first filed Gentoo bug: Please bear with me.

Created attachment 156627 [details, diff] invasive patch for host: armeb-softfloat-linux-uclibc
Created attachment 156631 [details, diff] more general patch This worked for me and seems to me more general than the preliminary patch I submitted before, but as I told I lack experience with configure-files.
I think there is something wrong with your setup. I've compiled this version of binutils under uclibc 5 times on a single host starting around Oct Sun Oct 21 12:12:45 2007 Are you sure this is not limited strictly to armeb- ?
this has come up before, but i havent been able to reproduce it maybe search bugzilla/gentoo embedded mailing list for more info
@solar: I assume with "setup" you mean the information you can get with "emerge --info", which I will attach just in case. Can you post yours too? Maybe someone can reproduce the bug that way. @SparKY: Yup, it did come up: * http://www.mail-archive.com/t2@t2-project.org/msg00488.html * http://article.gmane.org/gmane.comp.handhelds.openembedded.scm/4378 and * http://www.uclibc.org/lists/uclibc/2006-August/016088.html (already referenced in the mentioned bug http://bugs.gentoo.org/149398). Whereby the last one has a similar patch to mine. And while I was searching: dev-lang/tcc (http://bugs.gentoo.org/show_bug.cgi?id=133781) had a problem alike and you pointed out the missing link to "libm". Anyways, I am pretty sure of binutils/gas needing "libm" at least in my setup: If linked with uclibc and using softfloat. Maybe you guys succeeding have a floating point unit (FPU)? But it would be strange if that were the reason. I looked a bit deeper into the "gas/configure" script and I found the local variable "need_libm", which is used once in a "case ${need_libm} in"-statement which provides "-lm" at compile-time if necessary. BUT it was only set before once in gas/configure.tgt for a tic54x-* architecture. So, I improved my previous patch and integrated it a bit more in the given configure-script-structure and made it very specific to my architecture, it tests for ${generic_target} == "arm*-softfloat*-uclibc". I think the patch is safe to be integrated into the portage tree (could be 92_bla.patch in the patch-compilation). You probably could loosen the comparison to "*-softfloat*-uclibc" but I have no way of testing it.

Ups, the name was SpanKY not SparKY. Sorry.

binutils-2.18-r3 actually does build with the proposed patch on my NSLU2. As the patch really seems not to interfere with any other build environment than arm-softfloat-uclibc, I think it should be integrated in the tree.
*** Bug 254288 has been marked as a duplicate of this bug. ***
binutils-2.21.1 just built fine for me
