About build error (storage size of 'hostlist' isn't known)

[mr-shoji]

I tried to build EAR-4.3.1 on Rocky 9.4, Ubuntu 20.04.6.
I ran the following commands based on the documentation

autoreconf -i
./configure --prefix=/opt/ear CC=mpicc MPICC=mpicc MPI_VERSION=ompi 
make

However, the build failed with the following error message.
Is there any way to fix this issue?

Hello @mr-shoji .
We've just released a new version of EAR (v5.0).
It is strange you encountered problems while compiling the last version.
Anyway, if you still want to work with EAR, I recommend you to update to the latest version.
I'll enable Issue notifications to be aware if you (and other users) have any problem.

PS: In etc/examples you can find a set of scripts we usually use to compile EAR in our systems.

Regards,
Oriol
