Yugi,

One of my colleague helped and managed to fix the compilation by editing compil_tools.py

Near Line 900:

src_dir = path.join(cfg['root'], 'sources', 'utils', 'hermes')
source_hermes = copy_src_api(api_dir, src_list, src_dir)
#### HRW fix for Windows 10 ######	
# Add an api module to make hermes work 
source_hermes = api_dir + '\\src\\api_handle_var_t3d.f90 ' + source_hermes
return source_api, source_hermes

near Line 1035

     print("    ~> Compiling hermes api")
#    ld_flags = get_api_ld_flags('hermes', static)
#    compile_api_f2py('hermes', api_dir, source_hermes, '',
#                     ld_flags, f2py_name, fcompiler, compiler, silent)
    ld_flags = get_api_ld_flags('api', static)
    compile_api_f2py('hermes', api_dir, source_hermes, skip_source,
                     ld_flags, f2py_name, fcompiler, compiler, silent,
                    f2py_opt=f2py_opt)

We do not fully understand why the few lines edited fixed the problem, so we thought we would share here and ask for some feedback.

Thanks
Juliette

We still don't know why the solution that Juliette posted worked, but we have found a simpler solution, which others might find helpful also. There is no need to modify any python, just include this line in the config file: libs_all: -lgfortran -lquadmath With this, the hermes module compiles successfully. Michael Turnbull

Hi,

I am using python 3.9, windows 10 and v8p2r0.
I can compile clean using 'python compile_telemac.py' but when I am trying to use the class 'TelemacFile', I get the same error as the mentioned topic:

TelemacException: Error: unable to load the dynamic library _hermes.dll
You can check the environment variable: PYTHONPATH
No module named '_hermes'

I tried everything posted above but nothing worked for me. Can someone please help me to solve this issue?

nitesh OFFLINE Senior Boarder Posts: 73 Thank you received: 1	I tried both the above suggestions. It says ''f2py' is not recognized as an internal or external command, operable program or batch file.' Can you please have a look at the errors I got respectively and see if you recognize them? Thanks! Attachments: api_error.jpg (65KB) error_2021-05-21.png (247KB)

Michael_Turnbull OFFLINE Fresh Boarder Posts: 9 Thank you received: 4	I am using Anaconda python. f2py is one of the scripts available as part of Anaconda python. Perhaps you can check if you have f2py.exe on your PC somewhere. If so, you could add its location to your PATH.

nitesh OFFLINE Senior Boarder Posts: 73 Thank you received: 1	I defined the path in my computer's environment variables, it did not work. But then I moved f2py.exe to 'C:\opentelemac-mascaret\v8p2\scripts\python3' and it worked. Thank you so much :)
