Ubuntu 16.04 LTE
Non-Intel processor on computer
Intel SGX installed

Results of running /src/bin/testnet/teechain_deposits.sh:

~/Desktop/Teechain-master/src/bin/testnet$ ./teechain_deposits.sh
Mounting a RAM disk for server output in test directory!
~/Desktop/Teechain-master/src ~/Desktop/Teechain-master/src/bin/testnet
Starting two ghost teechain enclaves...
Spawning enclave ALICE listening on port 10001 in bin/testnet/test/alice.txt 
Spawning enclave BOB listening on port 10002 in bin/testnet/test/bob.txt 
Waiting until enclaves are initialized ...!.........................................................................................................................................................................................................

So far the enclave is not being created and the teechain_deposits.sh is stuck in this loop.
I see that because the alice.txt nor bob.txt has not added "Enclave created", then line 42 fails to break out of the while loop.
I tried manually executing line 49 to see what happens (./teechain primary -p $ALICE_PORT) and I received:
./teechain: error while loading shared libraries: libsgx_urts_sim.so: cannot open shared object file: No such file or directory
Which leads me to believe that there is possibly something wrong with my installation/configuration of the Intel SGX simulation mode.

I will provide updates as I continue looking at this, any further insight would be appreciated.

The SGX tests worked properly:

Hit a key....

However, when running teechain_send.sh I receive seg faults:

user@computer:~/Desktop/Teechain-master/src/bin/testnet$ ./teechain_send.sh
Mounting a RAM disk for server output in test directory!
~/Desktop/Teechain-master/src ~/Desktop/Teechain-master/src/bin/testnet

The computer I am running this on has 8GB of ram, I recall reading that the seg faults are usually due to too little ram.
