Missing fabm0d executable

[platipodium]

Dear Jorn and FABM community,

I followed the instructions on the FABM wiki for building the 0d host at https://github.com/fabm-model/fabm/wiki/0D-driver

The build instructions are:

mkdir build
cd build
cmake <FABMDIR>/src/drivers/0d -DGOTM_BASE=<GOTMDIR>
cmake --build . --target install

and should result in a full installation in ~/local/fabm/0d/. For me and others, the include, lib, and cmake installed directories are present and complete. But: the with bin/fabm0d executable is missing. How do I obtain this executable?

Hi Carsten,

I'm not immediately sure what's going on there. We verify that the fabm0d executable is created as part of our automated testing on Linux, and there it currently succeeds. The simplest explanation would be if you ran cmake differently, with cmake <FABMDIR> -DFABM_HOST=0d, but the instructions you cite above should be ok... What's the final output from your cmake --build . --target install command? it should mention which files it is installing, and where.

Cheers,

Jorn

hi jorn,

the command
% cmake --build . --target install

results in the output below, thus lacks any "bin" directory or "fabm0d" executable.
any help is much appreciated
best, kai

Hi Kai,

Can you try cat build/CMakeCache.txt | grep -E SOURCE_DIR and post its output here? It should include a line that starts with fabm0d_SOURCE_DIR:STATIC=. If that's not there, something must have gone wrong with the very first cmake command. In that case, I'd suggest deleting your build directory and rerunning the installation instructions above from scratch. If that does not result in -- Installing: ~/local/fabm/0d/bin/fabm0d, please post the full output of all commands here.

Cheers,

Jorn

Hallo Jorn,

$ cat CMakeCache.txt | grep -E SOURCE_DIR
fabm_SOURCE_DIR:STATIC=/Users/Lemmen/devel/fabm/fabm-official
yaml_SOURCE_DIR:STATIC=/Users/Lemmen/devel/fabm/fabm-official/src/yaml

Also fehlt die gewünschte Zeile fabm0d_SOURCE_DIR:STATIC=. .

Der Output des ersten CMAKE ist:

$  cmake .. -DFABM_HOST=0d

Hi Carsten,

Both those indicate that you ran cmake with <FABMDIR> as source dir, rather than <FABMDIR>/src/drivers/0d. If you use cmake ../src/drivers/0d -DGOTM_BASE=<GOTMDIR>, you're likely ok.

[platipodium]

You're right, that's what we should have done. Only that GOTM compilation fails (with up-to-date sources) when doing that.

cmake ../src/drivers/0d -DGOTM_BASE=~/devel/gotm && cmake --build . --target install

...

but I guess that is another discussion. I guess it should be made clearer in the documentation of the FABM0d host that it is insufficient to do cmake $FABMDIR -DFABM_HOST=0d, but instead that it is required to use cmake $FABMDIR/src/drivers/0d ...

hi jorn,

carsten and me (on macbooks with Ports installations) share the same problems.

cmake ../code/src/drivers/0d -DGOTM_BASE=/Users/wirtz/mossco/code/external/gotm/code

CMake Error at CMakeLists.txt:52 (add_executable):
Cannot find source file:

/Users/wirtz/mossco/code/external/gotm/code/src/airsea/short_wave_radiation.F90

in the most recent gotm pull I have "shortwave_radiation.F90" (without first "_").

---

after creating a softlink "short_wave_radiation.F90" that points to "shortwave_radiation.F90", the first cmake gets through.
hover, the second cmake ("cmake --build . --target install") runs into

[jornbr]

Glad there's progress! Both aspects (the cmake syntax and which GOTM version to use) are mentioned at the wiki page you referred to above, but if you have ideas how this could be made clearer, they would be very welcome. :-) Also, if you found incorrect/outdated instructions elsewhere, let me know.

NB to pull in the required stable GOTM, you could do git clone --recursive -b v6.0 https://github.com/gotm-model/code.git gotm6 (or download the stable release including submodules as mentioned on the wiki)

[platipodium]

Dear @jornbr, thanks a lot for helping us to make it work! Changing the gotm from development to v6.0 stable (git clone --recursive -b v6.0 https://github.com/gotm-model/code.git) resolved the above compilation issues.

I now have a working ~/local/fabm/0d/bin/fabm0d binary!

My THM for fabm0d

• make sure give to cmake the source path to the drivers/0d
• use GOTM version 6.0

[platipodium]

Just a side remark @kaiwirtz3 : if you use the outdated FABM0 version with the MOSSCO coupling framework, make sure to use GOTM v5.3.
