Re: Building 2.27 on CentOS

[Andreas Hubert <anhubert at googlemail dot com>]

To have a really clean environment for testing, I just tried it with a docker container based on centos/devtoolset-7-toolchain-centos7 and just added bison and make. So that’s my docker file:

```
FROM centos/devtoolset-7-toolchain-centos7

USER 0
RUN yum install -y --setopt=tsflags=nodocs bison devtoolset-7-make && yum clean all -y
USER 1001
```

>From there I was just running `configure —prefix=/my/new/dir` and then make
Still facing the same error:

```

And as a side note, if I try it with `make -j6` I get this error:
```

Any suggestions what am I missing or how can make this finally compile?
