glibc fails to build on buildroot-{sh4,sh4a,sh4eb,sh4aeb}-buildroot-linux-gnu, see below. Tested on git as of today (2b2e216ee0cb6894b0012316c20da9291ce14458): - make menuconfig - Select sh4 - Select "Build options -> libraries (both shared and static)" - Select "Toolchain -> C library (glibc)" (default version 2.24) - Select "Toolchain -> Enable C++ support" Everything else is default. Trying other versions of glibc doesn't seem to make any difference. It seems to happen on all sh4* variants apparently, though some more testing might be required there. Host gcc is 6.3.0.

I was able to reproduce Uwe's problem, and the patch proposed by Waldemar indeed fixes it. Waldemar, will you send a patch adding this to our glibc package ? Is it also needed for glibc 2.23 ?
Hi, I am to busy right now, may be initial reporter can prepare it? best regards Waldemar
Thanks, fixed in https://git.buildroot.org/buildroot/commit/?id=5f2cff973a8a64411d85ccb9d5c9a40962d67552.
Confirmed, thanks! All sh4* targets build fine here now.
