[Dune-devel] problema with poisson-pq2?

[Ed Scott Wilson Garcia]

Hi Oliver,

  It's good to know that it is simpler to merge core and staging modules together and do the dunecontrol all in that directory. Maybe that detail is in the dune website (it should be) and I just missed it, which would not be unusual.

A quick  look into the issue   https://gitlab.dune-project.org/core/dune-common/-/issues/191 confirms that $prefix/share/doc/dune-common/comm is empty after a make install. Also $prefix/share/doc/dune-localfunctions/comm is empty. Those are the only two comm paths in $prefix/share/doc for all core and staging modules.

$/usr/bin/find ./ -name comm
./dune-common/comm
./dune-localfunctions/comm

I'll do a repeat of the same compile+install in Gentoo and see what differs. It might take me a while since the weekend is in between, but I'll let you know what I find.

best regards,

Edscott

Hi Edscott,

> Changing the compile order from all core modules-->all staging modules to dune-common-->staging/dune-uggrid-->all other core modules-->all other staging modules efectively fixes the problem while trying to link poisson-pq2.cc.o. Four builds instead of two builds.

the core/staging distinction does not have anything to do with build order.
The order you describe above is the correct one, and it is the one that
dunecontrol should use automatically.

> The thorn in my side, from a the point of view of someone who wants to compile and install dune and all missing dependencies into a user directory, is that ---to keep things simple--- I want to do a "dune-common/bin/dunecontrol all" for modules in core, followed by make install. After that, use the installed dunecontrol to do the same for staging modules. This would entail just 2 builds. I guess I'm lazy.

It's simpler than that: Just do a "dune-common/bin/dunecontrol all" for core and staging together.

BTW, it's interesting to hear you are using a BSD system.  A while ago we received
a few bug reports from someone trying to package Dune for FreeBSD.  Like this one:

  https://gitlab.dune-project.org/core/dune-common/-/issues/191

Maybe you can help here?

Best,
Oliver

Otherwise a find_package(dune-uggrid OPTIONAL) in dune-grid with a warning that staging/dune-uggrid should be compiled first if dune-uggrid will be required later on.
