Building and Installing Occlum-HyperEnclave

[Vikrius]

Hey there, I was exploring different TEEs and came across the HyperEnclave paper. I found it very interesting and wanted to experiment with it.

I see in the docker container that Occlum is already built and installed. When attempting to make Occlum without any changes, I find that I am unable to get Occlum to build the make submodule to prepare a make on Occlum itself, I get this error:

error[E0658]: use of unstable library feature 'mixed_integer_ops'

error: build failed

When running the build command "OCCLUM_RELEASE_BUILD = 1 make", as per the Occlum compilation instructions in their documentation, I have no problems making Occlum.

However, when using "make install", I get this error:

CC <= /root/occlum/build/internal/src/pal/src_sim/base64.o
CC <= /root/occlum/build/internal/src/pal/src_sim/errno2str.o

make[1]: *** [Makefile:5: all] Error 2
make: *** [Makefile:118: install_bins_and_libs] Error 2

TLDR:
Trying to make and install an unmodified Occlum-HE from the source within the container, finding build errors.

Thank you for your time!
