The Intel(R) Software Guard Extensions Eclipse* Plug-in helps the enclave developer to maintain enclaves and untrusted related code inside Eclipse* C/C++ projects. To use this support, add SGX nature to the C/C++ project. See Adding SGX Nature to a Project for details.
Once the SGX nature is added to a project, you will have access to the SGX commands. SGX nature adds also a folder called sgx to the root of the project, and a Makefile inside it. All resources of the project managed by Intel(R) Software Guard Extensions Eclipse Plug-inare located inside this directory. You can build and run enclaves related code using GNU* Make tool through the Makefile.
The plugin is generating minimal but ready-to-work code skeletons, complete with their own Makefile having all the required make targets as to call sgx_edger8r tool to generate the proxies and bridges, compile these source, generate a shared object and finally, to sign the enclave with the sgx_sign tool. This provide a starting point you may build upon.
