Intel SGX, SampleCommonLoader sample code error sgx_enclave_common.h: No such file or directory

[donaldi95]

I wanted also to ask about an error i get.

It Is because of a library called sgx_enclave_common.h.

When i run the SampleCommonLoader code sample in HW mode, it gives me the following error:

App/sample.cpp:36:10: fatal error: sgx_enclave_common.h: No such file or directory 36 | #include "sgx_enclave_common.h"

Any idea on what should i do?

PS: I am following the SGX tutorial for Linux 20.04. My laptop had I7-8U generation. SGX is enabled, but it doesn't support DCAP.

Best Regards, Donald

Hello Donald,

Copy sgx_enclave_common.h from <sgxsdk>/include/ to <sgxsdk>/SampleCode/SampleCommonLoader/Include/

 Hello Jesus G.

I did this and i run into an other error.

GEN => App/sample.o
GEN => App/enclave_entry.o
/usr/local/bin/ld: cannot find -lsgx_enclave_common
collect2: error: ld returned 1 exit status
make: *** [Makefile:35: sample] Error 1

I also did make clean, and when i make again same error.

I did GEN => App/sample.o
GEN => App/enclave_entry.o
/usr/local/bin/ld: cannot find -lsgx_enclave_common
collect2: error: ld returned 1 exit status
make: *** [Makefile:35: sample] Error 1

i also did again Source {sgxsdk}/environent. And nothing changed.

Best Regards,

Donald

Hello Donald,

Check if /usr/lib/x86_64-linux-gnu/libsgx_enclave_common.so exists. If it does not exist, run:

$ sudo ln -s /usr/lib/x86_64-linux-gnu/libsgx_enclave_common.so.1 /usr/lib/x86_64-linux-gnu/libsgx_enclave_common.so

Run make again.

It seems that the SampleCommonLoader sample in the SGX SDK for Linux is buggy. It works fine in Windows.

Please open an issue in https://github.com/intel/linux-sgx/issues detailing these two problems. You will get the attention of the SGX engineering team in Github.
