TOPIC: Python API unable to load the dynamic library _hermes.so

Python API unable to load the dynamic library _hermes.so 3 years 8 months ago #37979

Hi,
Thanks for helping me!
So I added "options: api hermes_only" to my systel and if I type in the terminal config.py I get:
gfortranHPC:


+> Gfortran compiler 4.9.2 with open_mpi for a debian 8

+> root: /home/lune/v8p2r0
+> module: ad / api / artemis / bief
damocles / gaia / gretel / hermes
identify_liq_bnd / khione / mascaret / nestor
parallel / partel / postel3d / sisyphe
special / stbtel / telemac2d / telemac3d
tomawac / waqtel

Which seems fine?
But if I compile_telemac.py nothing more seems to be added to my telemac (see the message after compile_telemac.py attached).
Thanks again for helping me.

Thomas

Where did you add the line ? Because the api was not compiled.
Could you repost the updated systel.cfg ?

Sorry I just saw there was a options: hermes_only in gfortan HPC... :whistle:
i set it to options: api hermes_only. But then the compilation failed:

I added
"f2py_name: f2py3
pyd_fcompiler: gnu95"

to my systel and the compilation ran successfully and the wrap api file was created. But now when i try to import hermes I get:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /home/lune/v8p2r0/builds/gfortranHPC/wrap_api/lib/_hermes.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _gfortran_st_close

Thanks for your support.

You need to add the following lines:
f2py_name: f2py3
pyd_fcompiler: gnu95

Where f2py_name should match the name of your f2py executable and pyf_fcompiler the name of the compiler for f2py.
You can check that running:
f2py3 -c --help-fcompiler

Ok I just saw that you did it already.
I'll leave the information for other people.
For your error add -lgfortran to libs_all that should solve it.
