lharri73 / pysimlink Goto Github PK

Hi,

I have generated code to my Simulink model as in your description. Although a slprj folder is generated, it is not included in the zip folder. The structure looks like this:

• slprj
• [my_model]_grt_rtw
• [zip-folder]
  --- [a]
  ------ [my_model]_grt_rtw
  --- [b]
  ------ extern
  ------ rtw
  ------ simulink

When I add the slprj folder to the zip folder, it doesn't work either, because for example rtwtypes is not included in the slprj folder.
Do you know a solution how to make the project structure compliant with pysimlink?

Kind regards

This broke in the 1.2.0 release

Trying to run a model, while following each of the steps as laid out in the documentation, results in an error listed as, "ModuleNotFoundError: No module named 'fd_interface_c'" (where fd is the name of my model).

log:
-- Configuring incomplete, errors occurred!
CMake Error at CMakeLists.txt:2 (project):
Running

'nmake' '-?'

failed with:

no such file or directory

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage.

ode14x includes cmath. pysimlink interprets this as a model which does not exist.

Add to exclusion in model_ref_compiler.py:56

I have problems compiling a model that contains enums and nested bus objects. It seems that the struct_parser.py doesn't support this. When I try to implement some exceptions for these types the model compiles but it crashes when I read out the model (e.g. with get_block_param()).

I have attached a model that contains the things to reproduce the error.
Model.zip

I am unable to compile any model on Windows. It looks like it fails to run the test compile. Output below. I can compile on linux in a docker container, but have tried two different windows machines with VS 2017 and 2019 with the desktop C++ packages installed and it won't compile. I've played with paths extensively, trying 32 and 64 bit compiler versions.

Help please!

If constant blocks aren't appearing in block parameters, change this setting so they are tunable in the c api. Can be added to docs.

model_paths.py:138 will be emitted if multitasking is enabled OR if Classic Call Interface is not checked and/or (?) Single output/update function is not checked.

It's not required if matlogging is disabled (also not present and causes a compiler error). It is required when logging is enabled because we have to stop logging, otherwise there's a memory leak.

force_rebuild should clear the extracted file's contents and extract again

Under code interface, add signal to code mappings, provide an identifier, then set storage class to 'ExportedGlobal'. Should show up in signal map. I assume this causes it to coalesce into a real signal.

Trying to compile a model on a Window 10 machine using Python 3.12.2 but the following error gets thrown:

File "C:\temp\.venv\Lib\site-packages\pysimlink\lib\model.py", line 130, in _unlock
rv = msvcrt.locking(f.fileno(), msvcrt.LK_UNLCK, 1)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
PermissionError: [Errno 13] Permission denied

Commenting out line 71 self._lock() and 83 self._unlock() in model.py fixes the issue.

I cannot figure out from the documentation how to supply signal data to root level inports and log data from root level outports prior to each step.

I also cannot tell how to save and restore model states.

Can you please provide documentation and/or an example on these critical features?

Thanks,
Dan

I try to load a test model into pysimlink. I do a simple:

model = Model("testmodel", "./testmodel.zip", generator='MinGW Makefiles')

After compile step I get an error loading the generated module:

I set up a virtual environment in Python 3.9.9 with just the requirements needed for pysimlink. I also had to comment out the two lines for locking / unlocking as described in #17 .

The file "D:\Python\pySimlink\__pycache__\pysimlink\testmodel\build\out\library\testmodel_interface_c.cp39-win_amd64.pyd" is generated and is located in the given folder.
