Unable to Compile Linux SDK

Elephant — Wed, 26 Jul 2017 10:42:33 GMT

Hi,

I was trying to recompile my linux sgx sdk but I am having problems with messages.cc.

I am getting the following error:

../../../psw/ae/common/proto/messages.pb.cc:1389:10: error: unused parameter ‘deterministic’ [-Werror=unused-parameter]
bool deterministic, ::google::protobuf::uint8* target) const {

I have the following setup:

SGX version 1.8 (I tried 1.9 but was not working so reverted to 1.8 again with the same issue)
Linux 4.10.0-27-generic #30~16.04.2-Ubuntu SMP Thu Jun 29 16:07:46 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
libprotoc 3.3.0

I tried hacking the messages.pb.cc file to remote the reference to deterministic but I was having other errors. Is there a fix for this issue?

Thanks!

Kind Regards,
Elephant

Hi Elephant,

I built linux sgx sdk master branch by cloning https://github.com/01org/linux-sgx.git . Did not face any issue that you mentioned above.

Can you resync and try again ?

Hi Shivananda,

I tried it again with the clean repository. Reinstalled protocol buffer 3.3.2 and here's the error that I got:

This is a protbuf issue.

This is a protbuf issue. Either you have multiple versions and resulting in error.

There was some suggestion in below thread

https://github.com/BVLC/caffe/issues/3046

"Please try to remove the os versions of protobuf in /usr/lib/x86_64-linux-gnu. (Something like libprotobuf.*, libprotobuf-lite.*, libprotoc.*). There are two versions of protobuf will cause conflicts when compiling.

Then try to install newest version of protobuf"
