I encountered a problem when executing the "pip install l4casadi --no-build-isolation" command, what should I do？

Hi,

This looks like it is on a Windows system? Unfortunately, I do not have access to a Windows system. Thus, L4CasADi does not officially support Windows. I tried it some weeks ago but could not get it to work in a reasonable timeframe.

Best Tim

Thank you very much，Tim I tried using an ubuntu system and am currently configuring acados. Thank you so much for your work, l4casadi is a great tool！

Hi，Tim I have a few new inquiries I'd like to consult you about.

1. When installing acados, I encountered the following error while running the command 'make examples_c'. Do you have any good solutions to resolve this? g++ -o dense_qp.out dense_qp.o -L/home/ubuntu2004/acados/lib -lacados -lhpipm -lblasfeo -lm -lblas -llapack /usr/bin/ld: /home/ubuntu2004/acados/lib/libacados.so: undefined reference to `ocp_nlp_ddp_config_initialize_default' collect2: error: ld returned 1 exit status 2.When executing 'simple_nlp.py', I encountered such an issue, unsure how to address it.

For models which expects a batch dimension, the output should be a matrix of [1, d]. Thank you very much for promptly addressing my inquiries. Wishing you smooth workflow and joy every day.

Hi,

1. Sounds like this problem is with Acados and unrelated to L4CasADi? If so I suggest to seek help on the Acados Forum. Sounds like some linking error to me.
2. The examples was indeed broken. I just did a commit fixing it.

Hope this helps

Tim

Thanks again for your answer. l4casadi really helped me a lot.

hope you happy every day
