I have freshly installed a new CentOS 8.2 VM and tried it, I didn't hit no any issue for the compiling except some warnings.

@Patrick,

Checked the teuthology log I didn't see any suspecious error or warning could cause this, and the "config.h" header has been successfully created by automake tool:

2020-11-25T00:26:36.429 INFO:tasks.workunit.client.0.smithi089.stdout:configure: creating ./config.status

2020-11-25T00:26:37.080 INFO:tasks.workunit.client.0.smithi089.stdout:make  all-am

I am not sure whether is the automake tool's bug. Could you add the following PR when you're running the qa testing ? Let's see whether the contents in "config.h" header are all successfully created.

Thanks.

ACK, I'll include it.

Haven't seen this failure recently but did get this:

Probably not related.

This still seems the version.h not generated successfully.

2021-04-09T05:32:54.255 INFO:tasks.workunit.client.1.smithi200.stdout:config.status: creating config.h

This time the config.h was generated successfully too.

From https://www.gnu.org/software/automake/manual/automake.html, it seems the ffsb is using the old form of `AM_INIT_AUTOMAKE`:

If your configure.ac has:

AC_INIT([src/foo.c])
AM_INIT_AUTOMAKE([mumble], [1.5])

you should modernize it as follows:

AC_INIT([mumble], [1.5])
AC_CONFIG_SRCDIR([src/foo.c])
AM_INIT_AUTOMAKE
