Hi Li,

thanks for your review!

Maybe this:

Debian / Ubuntu
# apt install gcc make pkgconf autoconf automake bison flex m4 linux-headers-$(uname -r) libc6-dev

OpenSUSE / SLES
# zypper install gcc make pkgconf autoconf automake bison flex m4 linux-glibc-devel glibc-devel

Fedora / CentOS / RHEL
# yum install gcc make pkgconf autoconf automake bison flex m4 kernel-headers glibc-headers

I'd prefer it in simple form (single line) + I thought bison is more common than
byacc (but maybe I'm wrong). I'm not a big fan of sudo (but can add it there).
+ Added headers and gcc. But on the other hand I wanted to have package reference in
travis/*.sh (where are missing some packages which are installed by default with
gcc, e.g. , but it does not harm to have it offline.

Should I remove links to the tools? And we obviously don't list a compiler.

Yep, that was the intention of this late evening patches :).

Kind regards,
