Run ngspice from shell

[struchenbachen]

Hi, first of all thank you for the app, it is very useful for my work. I have question: is it possible to run ngspice having its C source code? https://github.com/imr/ngspice If yes, how is the procedure? Thank you!

The generic procedure to compile a package from it source code is:

• download and compile the SDK on your main computer: https://github.com/holzschu/wasi-sdk
• download the source code for ngspice
• replace config.sub and config.guess in ngspice source code wit the versions from the wasi-SDK
• setup the compiler and sysroot as the versions from the wasi-SDK
• run ./configure --host=wasm32-wasi in the ngspice source code directory, then make. (this may require setting some more options in configure, depending on the package)
• if all goes well, you end up with a file named ngspice, which you can move to the iPad.
• you execute this file with wasm ngspice.

The current limitations are: no interactive input from the keyboard, and no graphical user interface (so, for ngspice specifically, these are pretty strong limitations).

Thanks for the answer. I will try to follow the instructions and let you know how it goes.
