Hi,

THis means that Python could not decode one of the character in f2py listing.
A temporary bypass to get the error message would be to replace:
execpt.output.decode('utf-8')))
by
execpt.output))
In compil_tools at line 926

An rerun we should get the error message.

This replacement does enable the error message, which is actually induced by the failure of f2py compilation in the subprocess.

And could you post the error message ?

Hi,
Did you manage to solve this situation?

I came through the same issue...

I've compiled v8p1 with python 3 script "compile_telemac.py', but when I am on the spyder framework to use TelemaFile function, it gives me the same error describd in the topic.

Regards,

Hi,

Yugi has clarified, you've missed api compilation. So the Class "HermesFile" cannot find the f2py module "_hermes".

The problem has not been solved yet, due to failure of compilation.

Hello,
I am also trying to compile the api but I have been unable to do so.
I attach my configuration file and the compilation log with the errors encountered.
I am using the current trunk, Windows 10, MINGW-W64 compilers and WinPython 3.7.1. f2py is installed with the latest numpy.
I would greatly appreciate any help.
Best Regards,
Costas

Hi Costas

I'm not fully sure I could help you with you own configuration...
Nevertheless I compiled Telemac API on my windows laptop (W10 with gcc 4.8 and python 3.6) but only in manual mode...
After the automatic compilation, I manually run the 2 f2py command line for both api and hermes...
As the command line are directly linked to your configuration, I advise you to proceed as I do. In the script compil_tools.py, remove the --quiet option of f2py line and also print the command line.
On my computer I also noticed I have to place a copy of vcruntime140.dll in the directory wrap_api\lib

As an example of the command line I enclosed the one I have for my computer in V8P1
f2py.py -h c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\lib\api.pyf -m _api c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_var_t3d.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_var_t2d.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_var_sis.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_var_art.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_var_wac.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_handle_error.f90 c:\opentelemac-mascaret\v8p1\builds\wingforsapi\wrap_api\src\api_interface.f90  skip: get_boolean_t2d_d get_double_t2d_d get_integer_t2d_d get_string_t2d_d get_var_size_t2d_d set_boolean_t2d_d set_double_t2d_d set_integer_t2d_d set_string_t2d_d get_double_array_t2d_d get_integer_array_t2d_d set_double_array_t2d_d set_integer_array_t2d_d get_boolean_sis_d get_double_sis_d get_integer_sis_d get_string_sis_d get_var_size_sis_d set_boolean_sis_d set_double_sis_d set_integer_sis_d set_string_sis_d get_double_array_sis_d get_integer_array_sis_d set_double_array_sis_d set_integer_array_sis_d get_boolean_t3d_d get_double_t3d_d get_integer_t3d_d get_string_t3d_d get_var_size_t3d_d set_boolean_t3d_d set_double_t3d_d set_integer_t3d_d set_string_t3d_d get_double_array_t3d_d get_integer_array_t3d_d set_double_array_t3d_d set_integer_array_t3d_d get_boolean_art_d get_double_art_d get_integer_art_d get_string_art_d get_var_size_art_d set_boolean_art_d set_double_art_d set_integer_art_d set_string_art_d get_double_array_art_d get_integer_array_art_d set_double_array_art_d set_integer_array_art_d get_boolean_wac_d get_double_wac_d get_integer_wac_d get_string_wac_d get_var_size_wac_d set_boolean_wac_d set_double_wac_d set_integer_wac_d set_string_wac_d get_double_array_wac_d get_integer_array_wac_d set_double_array_wac_d set_integer_array_wac_d  :

Hi,

I think this is an issue with the order of the libraries. (This is a pain in the a** with static libraries).
This could be that libs_all should be placed before in the f2py command.

Can you try by modifying that in compilations/compil_tools.py line 727 in get_api_ld_flags:
    ld_flags += cfg['libs_all'] \
        .replace('<root>', cfg['root']) \
        .replace('\n', ' ')
by
    ld_flags = cfg['libs_all'] \
        .replace('<root>', cfg['root']) \
        .replace('\n', ' ') + ' ' + ld_flags

And see how it goes.

By the way for your information on the trunk we added a way to compile in dynamic for Windows/Mac. It seems to work (still needs some feedback) by adding dyn in options.
This means you will need all prerequisites in dynamic.

First, will follow Yoann's (easier?) path and if that doesn't pan out, I will try the 'manual' way Christophe suggested.
It seems that the change in compil_tools.py reduced the number of undefined reference errors, or errors in general. You can tell by the size of the log that reduced by 150kb!
Here is the new log:

I don't knowh how the pre-requisites are compiled by default. but I will check it out when I get the chance.

Did you take care about the vcruntime140.dll?
I don't remind well but I know this solved some problem for me...
