Error installing SGX driver - "Cannot use CONFIG_STACK_VALIDATION=y"

[Gokhale__Sushant]

Hi,

While trying to install the Intel SGX driver from the official site, I am getting the following error:

dell@dell:~/Downloads/linux-sgx-driver-master$ make
make -C /lib/modules/4.15.0-36-generic/build SUBDIRS=/home/dell/Downloads/linux-sgx-driver-master modules
make[1]: Entering directory '/usr/src/linux-headers-4.15.0-36-generic'

Note that I already have a following directory on my desktop( and I don't know if its related or not):

dell@dell:~/Downloads/linux-sgx-driver-master$ ls /opt/intel/sgxdriver/
uninstall.sh

Requesting to please help me as to how the issue is to be resolved.

Hi Sushant. It looks as though the driver might have been built even though you got that warning. But, to get rid of the warning, try installing one of those packages it mentions. For example, on Ubuntu you would do this: sudo apt install libelf-dev Regards. Scott

Thanks Scott. The driver was already built and I didn't need to install the package.
