Cannot include certain header files in enclave project.

Hello, everyone.

I am facing difficulty while trying to include certain header files in enclave project. For instance, the following statements result into a warning message (cannot open source file):

#include <malloc.h>

#include <atomic>

Although the application project can successfully include these header files, the enclave project fails to do so. Any idea?

Thanks.

Try including and

Try including <stdlib.h> and <stdatomic.h>

Hi Juan,

Thanks for your reply.

Is it possible to include standard C++11 headers like <atomic> in an enclave project?

On Windows yes, because we

On Windows yes, because we support C++11.

The Linux SGX SDK doesn't support C++11 yet. However, there's a branch in github that shows a preliminary effort. It's not product quality though.

Thanks for your response.

Thanks for your response.

I am using Windows.

But, when I tried to include atomic header in an enclave project (#include <atomic>), I got an error "cannot open source file atomic".

Do I need to change any project configuration settings?

Hi,

I have used the same header file in my project and it is not showing any error. Which version of SGX and Visual studio are you using?

Are you using the SGX SDK 1.7

Are you using the SGX SDK 1.7 release and the libc++ library?

Your enclave should include $(SGXSDKInstallPath)include\libc++ instead of $(SGXSDKInstallPath)include\stlport

Thanks a lot Juan. It worked.

Thanks a lot Juan. It worked. Previously, I was using stlport in my enclave project.

Hi Anusha, I am using SGX SDK 1.7 and Visual Studio 2015 Professional.
