Does PySpice run with the iOS app Juno?

[Kyhiendo]

Environment (OS, Python version, PySpice version, simulator)

Expected Behaviour

PySpice 1.5 seemed to install fine, in an iOS app called Juno

Actual Behaviour

An example, that ran in Spyder (Anaconda), did not run in Juno. Error message is as seen in the screen shot attached

Steps to reproduce the behaviour

can you compile ngspice in juno?

Hi,Yes, PySpice appear to install ok in Juno.Can I send you a PySpice script that I tried to run in Juno?  You can see the error messages from that.Thanks,Hien DoOn Nov 23, 2024, at 2:28 PM, Kreijstal @.***> wrote: can you compile ngspice in juno?

sure, but can you send the stderr and stdout
