SGX developement environment

I need to test run the following code SGXROP for my Bachelor's project.

To achieve this, I want to have a development environment for SGX without the required hardware (both my computers have SGX compatible CPUs but I would prefer to have an environment that doesn't rely on it, so that I could share my work with my professors easily without having them to buy a CPU) and I need to be able to have such an environment on Windows 10 and Linux Manjaro (based on Arch-Linux). So I thought I could use Intel's SDK for Linux on an Ubuntu-20 VM which I could use and move on both my computers. I tried to build the SDK by myself following the above-mentioned guide and to use the Ubuntu 20 SDK installer. Both result in the following error when making the SampleEnclave application :

/opt/intel/sgxsdk/SampleCode/SampleEnclave$ sudo make SGX_MODE=SIM
make[1]: Entering directory '/opt/intel/sgxsdk/SampleCode/SampleEnclave'
GEN  =>  App/Enclave_u.h

/usr/local/bin/ld: /opt/intel/sgxsdk/lib64/libsgx_urts_sim.so: undefined reference to `get_launch_token'

make[1]: *** [Makefile:235: app] Error 1
make[1]: Leaving directory '/opt/intel/sgxsdk/SampleCode/SampleEnclave'
make: *** [Makefile:180: all] Error 2

So I have two questions.

  1. In my use case, have I chosen the best option by opting for an Ubuntu VM and trying to use de SGX SDK in Simulation mode (is it sufficient?)?
  2. If it is a good choice, what is my mistake in my attempt to set up a development environment and run the SampleEnclave application?

Thank you to everyone for taking the time to read my questions!

Yes, SGX Simulation Mode allows you to simulate the SGX instructions without an SGX processor:

The simulation mode works in the same way as the debug mode except the fact that true hardware is not exercised, instead the Intel® SGX instructions are simulated in software.

The error is probably due to not setting the correct shell variables. Run:

source /opt/intel/sgxsdk/environment
