Error Intel SGX on Linux

Jump to solution

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!

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

João R.,

Which specific Linux are you working with?
