Any comments will be appreciated. Thanks!!!!

And I'm sure the app is linking to the correct libsgx_urts.so.

Make sure PSW installer has been installed. Do not set LD_LIBRARY_PATH=/opt/intel/sgxsdk/lib64/ libsgx_urts.so under system folder instead of the one under /opt/intel/sgxsdk/lib64/ should be used

you-n-g commented 7 years ago

@zhaohuidu I use /usr/lib/libsgx_urts.so and It works!! Thanks very much!

So /usr/lib/libsgx_urts.so comes from the PSW and it is the library for production environment on the hardware. And /opt/intel/sgxsdk/lib64/libsgx_urts.so comes from the SDK and it is only for development.

Did I understand it correctly?

zhaohuidu commented 7 years ago

Yes.

Yonggie commented 5 years ago

can any body tell me where to modify the DL_LIBRARY_PATH mentioned above?????

andyzyb commented 5 years ago

As the answer above, you usually don't need to set LD_LIBRARY_PATH and it will use the right uRTS in /usr/lib

Do not set LD_LIBRARY_PATH=/opt/intel/sgxsdk/lib64/

buttercutter commented 4 years ago

May I know why I do not have this file /usr/lib/libsgx_urts.so installed ?

[phung@archlinux HelloEnclave]$ locate urts /opt/intel/sgxpsw/aesm/liburts_internal.so /opt/intel/sgxpsw/lib64/libsgx_urts.so /opt/intel/sgxsdk/include/sgx_urts.h /opt/intel/sgxsdk/lib64/libsgx_urts.so /opt/intel/sgxsdk/lib64/libsgx_urts_sim.so /opt/intel/sgxsdk/pkgconfig/libsgx_urts.pc /opt/intel/sgxsdk/pkgconfig/libsgx_urts_sim.pc [phung@archlinux HelloEnclave]$

I had a similar error but it went away when I ran the compiled app using the sudo command.

tomoyasuzuki commented 1 year ago

I'm trying to run SampleEnclave with HW mode, but I got same error. How do I use libsgx_urts.so in /usr/lib? I have not set LD_LIBRARY_PATH, but the library in /opt/intel/sgxsdk/lib64 is used. I tried to set SGX_LIBRARY_PATH=/usr/lib in Makefile, but I got same error.

Thank you.

I meet the same problem with you, do you solve the problem?

Thank you.
