I am trying to use the TSS library tpm2-tss with a simulator (any simulator that works). The documentation for tpm2-tss states I have to use the microsoft simulator but you mentioned I have to use IBM's simulator (see my previous email). I have the microsoft simulator executable, which I initially tested (my first email). Based on your instructions, I then tried to compile IBM's simulator, which failed (see my previous email ' this code will not compile on Windows or Linux').
