IO Demo not compiling

[Mohamed Layouni]

Hello, 

I tried to compile the IO_demo provided with SCALE-MAMBA, and it failed as shown below. No schedule (.sch) file was created. Am I doing something wrong? Or is this an issue with the IO_demo code itself? If so, how to fix it?

Note, the tutorial program, on the other hand, compiled and worked fine.

More generally, if I have 3 players, and I want them to compute a simple sum of their private inputs, and then reveal it to all 3 of them, how do you that in SCALE-MAMBA? I tried the second block of code below, but it did not compile. Any thoughts?

Thanks, 

Mohamed.

Hi

SCALE-MAMBA is no longer maintained or supported
