I am trying to run a C sample on Intel Edison like in :

https://github.com/neeraj-khanna/azure-iot-sdks/blob/master/c/doc/run_sample_on_intel_edison.md

I am trying to Build the Azure IoT sdk , I Set necessary environment variables 

export CFLAGS="-I/home/root/qpid-proton/proton-c/include"

export CPPFLAGS="-I/home/root/qpid-proton/proton-c/include"

export LDFLAGS="-L/lib/"

and try to run ./build.sh in azure-iot-sdks/c/build_all/Linux but I am getting a error :

-- The C compiler identification is GNU 4.9.1
-- The CXX compiler identification is GNU 4.9.1
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works

-- Detecting CXX compile features - done
CMake Error at CMakeLists.txt:27 (add_subdirectory):
  add_subdirectory given source "azure-c-shared-utility/c" which is not an
  existing directory.

Many thanks in advance !

The instructions for the Intel Edison running Yocto have been updated. https://github.com/Azure/azure-iot-sdks/blob/master/doc/get_started/yocto-intel-edison-c.md Have you used the --recursive option when cloning the SDK repo? This is now necessary as the SDK is using sub module to use other libs sitting on other repos. Hope this helps

The --recursive option isn't supported on the git client that is default on Edison.

There are 3 options:

  1. Manually clone all of the submodules. This is error prone, especially if submodules update or change.
  2. Clone onto a different system and use your favorite transfer program to get it onto the Edison.
  3. Build your own private git client on Edison and use that one instead.

I personally use the BitVise ssh client on my Windows machine to transfer my Windows clone to my Edison. I do all of my file editing on my Windows machine and I use https://github.com/avranju/rsync to keep the Windows machine and the Edison in sync. It's not a perfect workflow, but it works for me, especially when I use the Visual Studio GDB extension to debug (https://blogs.msdn.microsoft.com/vcblog/2015/11/18/announcing-the-vs-gdb-debugger-extension/)
