Strange error due to import about astminer

[antonio-mastropaolo]

@ALL

I just tried from on a fresh virtual machine(ubuntu 64-bit), and it worked smoothly!
Even if I still get this message
"
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
.........
"
now the script writes all the files I need.
TBH, I don't know what happened before.
Anyway Thank you all for your time :)

hi @antonio-mastropaolo, thank you for the report. I'll have a look asap.

[vovak]

@antonio-mastropaolo could you please confirm if there is still output in results/c regardless of the error?

[antonio-mastropaolo]

@vovak Yes, but they're empty

[vovak]

Looks like the reason is either the error in the last line, which is not related to slf4j, or other problems with the C parser. Could you please share the output of java --version in your environment?

[antonio-mastropaolo]

Ook I see, this is the java version I have:

openjdk 15 2020-09-15
OpenJDK Runtime Environment (build 15+36-1562)
OpenJDK 64-Bit Server VM (build 15+36-1562, mixed mode, sharing)

[vovak]

Thanks. Would it be an option for you to share a (minimal) example of input where it fails? It works fine in my environment (Catalina, openjdk15) with a sample input. I build astminer from master-dev before running ./cli.sh

[antonio-mastropaolo]

@vovak Yep sure. Here the sample I'm trying to make it works

int sim_lifted_irk_integrator_calculate_args_size(sim_dims *dims, void *submodules_)
{
    sim_lifted_irk_integrator_submodules *submodules = (sim_lifted_irk_integrator_submodules *) submodules_;

    int size = sizeof(sim_lifted_irk_integrator_args);

    int ns = dims->num_stages;
    size += ns * ns * sizeof(double);  // A_mat
    size += ns * sizeof(double);  // b_vec
    size += ns * sizeof(double);  // c_vec

    size += sizeof(Newton_scheme);

    make_int_multiple_of(8, &size);

    size += ns * sizeof(double);  // eig

    size += ns*ns * sizeof(double);  // transf1
    size += ns*ns * sizeof(double);  // transf2
    size += ns*ns * sizeof(double);  // transf1_T
    size += ns*ns * sizeof(double);  // transf2_T

    size += 2*sizeof(external_function_fcn_ptrs);
    size += submodules->forward_vde.calculate_args_size(&sim_lifted_irk_forward_vde_dims, NULL);
    size += submodules->jacobian_ode.calculate_args_size(&sim_lifted_irk_jacobian_ode_dims, NULL);

    make_int_multiple_of(8, &size);
    size += 2 * 8;

    return size;
}

I also want to ask you, if we need to import all the dependencies or we can discard them.
For example, in the example I post above _ make_int_multiple_of_ is not defined.
Can be this a problem?

Thank you for your time :)

hi @antonio-mastropaolo,

Importing the dependencies is not necessary, as code is merely parsed for paths extraction.
When I place the snippet above to results/prep/example.c and run the cli.sh command with arguments just as you've provided, it works, and the output looks OK.

It's a classic it-works-on-my-machine, but I'd love to help you get it to work.

What OS do you use?

[antonio-mastropaolo]

hi @vovak

I really appreciate your help :)
I'm using macOS Big Sur 11.1. FYI I've already tried on another machine(ubuntu) and got the same problem.
At this stage, my only guess is that it could be something related to the java version.

I'm using openjdk 15 2020-09-15

Hi @antonio-mastropaolo! Wild guess, what is the path to the file that you're trying to parse?

[vovak]

@antonio-mastropaolo great! Please let us know if you encounter it again.
