Error Intel SGX on Linux

João_R_ — Tue, 04 Apr 2017 17:37:16 GMT

Hi. I'm trying to install mei for Linux: https://software.intel.com/en-us/file/37961-mei-712025zip

But when I try to make "make" I got:

: error: expected ‘,’ or ‘;’ before ‘__MODULE_STRING’
__MODULE_STRING(AMT_WD_VALUE)
^

And also:

error: implicit declaration of function ‘mdelay’ [-Werror=implicit-function-declaration]
mdelay(10); /* Wait for hardware disconnection ready */

I'm trying to install this because in the Intel-SGX: https://github.com/01org/linux-sgx , there are an example of SealedData that gives me the error:

Replay Protected DRM operation:
cannot get platform service capability, error code = 0x4001
Initialization the DRM failed.

Any help with this? Thank's in advance!

João R.,

Which specific Linux are you working with?

I solved the problem, to

João_R_ — Thu, 06 Apr 2017 10:30:00 GMT

I solved the problem, to acomplish that when I enabled MEI and install other required software (JHI, etc.) after PSW installed, then I needed to re-install PSW to trigger the initialization process.

Further information can be found in https://github.com/01org/linux-sgx/issues/93

Thanks for the help

Joao,
