[Dune-devel] problema with poisson-pq2?

[Ed Scott Wilson Garcia]

Thank you Oliver and Carsten,

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 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 would be nice to promote dune-uggrid to the core modules and have a find_package(dune-uggrid REQUIRED) in dune-grid. Maybe for the next Dune release (I'm using branch releases/2.7). 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.

Examining the FreeBSD port for dune-grid, the first case is met. IOW, it depends on dune-uggrid.

my 2 cents.

Best regards,

Edscott

it seems that you have UGGrid but the UGGrid dune bindings
are not build into the dune-grid library. Did you maybe
build dune-uggrid manually after dune-grid? In order to
build the dune bindings for UGGrid you have to build
dune-uggrid _before_ dune-grid. If that's the reason for
your problem, simply rebuilding dune-grid (and then all
dependent modules like dune-functions) should fix the issue.

Best,
Carsten
