When building the freedom-u-sdk toolchain on Ubuntu 18.04 LTS, I get this error:

freedom-u-sdk builds on Ubuntu 16.04. It does not build on Ubuntu 18.04 without patches to fix versioning problems. If you cd into buildroot, and checkout the sifive branch, you can get the patch you need to make it build on Ubuntu 18.04. It is the last commit on the sifive branch. At least I think that is the only patch you need. I haven’t tested this recently.

Thanks a lot, Jim.

I switched buildroot to the sifive branch. I still get the same error when running make from freedom-u-sdk.
It is the only error. make -k completes fine. I had to install autotools-dev on Ubuntu 18.
