<div>Hi all,<br>
<br>
</div>
The NEMS build system, NEMSAppBuilder, is
causing a lot of problems, especially for the
atmospheric model developers. We plan on
replacing the build system. What do you want
out of the new build system? What do you
dislike about the old one?<br>
<br>
Some questions to ponder:<br>
<br>
</div>
<div>- How should the build system work
internally? Shell script? Make? Cmake?<br>
</div>
<div><br>
- How should you run the build system? Shell
script? Run "make?" Run a GUI?<br>
</div>
<div><br>
</div>
<div>- When do we replace the build system? Do we
do it now, and risk breaking coupled systems?
Do we wait until we can test it with the coupled
applications?<br>
</div>
<div><br>
</div>
Feedback thus far:<br>
<br>
</div>
1. It is difficult to navigate the 1900 line
NEMSAppBuilder to figure out how to change the build
commands. <br>
<br>
</div>
2. Some users want to be able to manually build the
NEMS without running an overarching script.<br>
<br>
</div>
<div>3. Some users want a simple graphical interface to
select components and build the NEMS. (Yes, there are
users that want this.)<br>
</div>
<div><br>
</div>
4. Sometimes, components compile with options that are
incompatible with the linking options. This is because
each component has its own configuration system. This
causes problems, as we saw with FV3.<br>
<br>
</div>
5. The logic for building a component is in the NEMS
framework level. Any time a component's build system
changes, the NEMS framework has to be updated, breaking
applications that use older versions of the component.
This forces applications to use non-trunk versions of the
NEMS.<br>
<br>
</div>
6. The NEMS/src/configure script contains
application-specific logic. This also forces applications
to use non-trunk versions of the NEMS.<br>
<br>

Sincerely,<br>
