error code 307 in building RA sample under VS2019 & 2017 community and win10

SunnySun — Mon, 23 Aug 2021 13:14:11 GMT

Hi, Intel

When I build the RA sample code of sgx-ra-sample under VS2019 & 2017 community and win10, there are two errors of MSB 307 and the code is 1 and 5. The screen shot as follows.

I suspect this error may due to insufficient permissions when building sp and mrsigner, but I still encounter these two problems when I open the RA project with administrator permissions.

Can you tell me how to fix this problem. Thanks

Hello SunnySun,

The build events associated with the projects mrsigner and sp need to be modified.

In mrsigner, in the Post-Build Event, change $(IntDir) to $(OutDir).

Edit mrsigner -> Properties -> Build Events -> Post-Build Event -> Command Line: "$(TargetPath)" $(IntDir)enclave_sigstruct_raw > $(IntDir)enclave_mrsigner.txt -> "$(TargetPath)" $(OutDir)enclave_sigstruct_raw > $(OutDir)enclave_mrsigner.txt

In sp, in the Pre-Build Event, add ..\ to policy.in.

Edit sp -> Properties -> Build Events -> Pre-Build Event - Command Line: powershell -command "$mrs=Get-Content -Path ..\mrsigner\$(IntDir)enclave_mrsigner.txt; ( ( Get-Content -Path ..\policy.in -Raw ) -replace '@MRSIGNER@',$mrs ) | Set-Content $(IntDir)policy.cmd"

Sincerely,

Hi, Jesus G.

Thanks for your help. I have solved these two problems in VS 2017, and the problem in project mrsigner in VS 2019.

However, in the VS 2019, the problem still exists in the project sp. I don't know if it is related to the version of VS.

Sincerely,

SunnySun

Hello SunnySun,

The problem seems that the command is not able to find the policy.in file.

The default location of policy.in is under sgx-ra-sample/vs/policy.in.

During the pre-build event, the powershell command is executed from directory sgx-ra-sample/vs/service-provider. Hence we place ../ in front of policy.in in the powershell command line so that it can policy.in one level up.

So, knowing that the powershell command runs in sgx-ra-sample/vs/service-provider you have to tell the powershell command the correct relative path to policy.in.

This works on my VS 2019 environment.

Sincerely,

Jesus G.
