I'm expecting this to fail until the #898 will not be solved. For this I proposed two alternative solution in #900 and #901.

Let's wait until #901 is merged. Feel free to ping me in case I forgot about this PR. 🙂

Got this error while trying to compile.

Could you please fix the error? Let us know if you need any help. 🙂

Hi @Panquesito7. Thanks for your time.

This should fix ... if I remember well as it didn't reproduce on my env.
Knowing what compilation parameters are used to check will help.
