Do you actually use/need sh64 support? We're thinking of removing/deprecating it.
Well, I don't need it personally (at the moment), but we're trying to cross-compile our software (sigrok, open-source test&measurement project, see www.sigrok.org) for as many platforms as possible in order to catch any portability issues. We're using buildroot-built toolchains and sysroots for that since it's quite convenient. See e.g. http://sigrok.org/jenkins/job/libserialport/ http://sigrok.org/jenkins/job/libsigrok/ I don't know if we currently have users for sh64 or not, but that should not be relevant for this issue really. I guess the question is whether mainline glibc supports sh64 at all or not. The text "configure: error: The sh64 is not supported." suggests the latter. But I didn't check whether that's actually true or an incorrect error is emitted (and/or whether sh64 support is planned to be added to glibc). Note: I haven't tried the eglibc option for sh64 in buildroot, maybe that one does have support (?)
We've now marked sh64 as deprecated in Buildroot. According to the commit log: sh64: deprecate support for this dead architecture As discussed on the mailinglist, this should be deprecated before removal.
