Using gcc 8.3 with c++14 or c++17 to compile enclave

[shmoo]

Although the documentation of the Linux Developer Refernence says that the enclave only works with the c++11 standard. I noticed that with gcc 8.3 it is possible to build the enclave in c++14 or c++17 mode.

Of course only as long as you don't use functionalities that are not allowed by the Intel SDK.

Why does this work? Is this allowed or can I introduce an unwanted bug?

Hello Shmoo,

You are correct. As long as you use only the features allowed by the SGX SDK you should be okay. C++14 and C++17 are incremental improvements. Table 38 of the SGX Developer Reference for Linux lists the supported C++11 language features, which also apply to C++14 and C++17.

However, it is important to keep in mind that when a company says that a configuration is not supported, it means that the company has not tested or validated that configuration. It may or may not work. If it doesn't work, the company may not be able to help.

Sincerely,

Jesus G.
