For unsupported C++ functions

sera_l_ — Mon, 05 Jun 2017 07:41:07 GMT

I want to change my cpp codes to SGX code. But there are some issues related with unsupported C++ functions(or classes) like iostream, sstream.

Should I make ocalls for them to use this features?

And there is one more question.

I found some interfaces about unsupported class at SGX SDK (e.g sgxsdk/include/stlport/stl/_sstream.h)

Does It mean that is it working when I replace "<sstream>" to "<stl/_sstream.h>" in my default c++ codes? I tried to do this but I faced the problem that the header file in sdk is pointing at the untrusted code. In more details, the header file "_threads.h" in sdk is pointing at "/usr/include/pthread.h". so the redefinition type error happended.

Please help me :)

Hi,

Question No 1: Yes.

Question No 2: Could you please tell me which version of Visual Studio are you using to develop SGX application? Use the latest SDK and Visual Studiuo 2015.

Don't include files from

Don't include files from stlport/stl directly.

We removed unsupported header files from the stlport directory, but only modified supported header files in stlport/stl.

For example, if sstream is not included in stlport, then you should not include stl/_sstream.h
