Yup, I backed off those glibc changes and I could build, so that seems to be the problem. I guess if I want to build a complete toolchain with bootstrap I will need to update the libm that is in /lib. Steve Ellcey

Bootstrap problem with genatautomata and sysroot
I am trying to do a bootstrap build of GCC using a newly built glibc in a non standard location on my aarch64 platform (thunderx). This was working up until a week or so ago but now I am running into a problem I haven't seen before: build/genautomata /home/sellcey/test-tot/src/gcc/gcc/common.md /home/sellcey/test-tot/src/gcc/gcc/config/aarch64/aarch64.md \ insn-conditions.md > tmp-automata.c build/genautomata: /lib/aarch64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by build/genautomata) Makefile:2326: recipe for target 's-automata' failed Has anyone else seen this? I am building binutils and an initial GCC into a sysroot location, then I build glibc using that GCC and install it into that sysroot location and finally do a full GCC build with bootstrap. It is the final bootstrap build that fails. If I do a non-bootstrap build of the final GCC then it works. I looked through the patches for the last couple of weeks to see if I could identify what changed here but I haven't found anything. Maybe it was something in glibc that changed.
