Thanks for the bug report. Since the regression was introduced between 2017.02.3 and 2017.02.5, could you do a "git bisect" to find where the problem is ? I've submitted a patch that fixes this issue, see https://patchwork.ozlabs.org/patch/798221/. |
Created attachment 7146 [details] buildroot .config With arch i386 (see config file), The latest buildroot versions fails to compile glibc (2.24 or 2.25). tested with : 2017.05.2 and 2017.02.5 The same config works fine with buildroot version 2017.02.3. ... /home/dev01/data/projects/buildroot-2017.02.5_X86_32/output/../../../toolchain/2017.02.5_X86_32/host/usr/bin/i686-buildroot-linux-gnu-gcc
