    Intel IoT Eclipse C++ Build and Run Problem on Edison


      I can build and run Eclipse C example projects on my edison arduino board as described in the below link. The example in the guideline builds and runs the code in "Debug" mode. So the code only keeps on working on edison while eclipse is running. When I exit from eclipse, the code stops working on edison at the same time.


      As a solution I tried to build the projects in "Release" mode. But it's impossible to build any project successfully in this mode. Each time I get some building and making errors. Is there any guideline that explains configuration details to build the projects in Release mode? Or any alternative solution to run the projects independent from eclipse?

          Hi ihacivelioglu


          I think you could get more information and appropriate help about this in the XDK forums. Even though, have you tried to run the code in background using the terminal console? You could save the code in a directory of your Edison and run the code in there.




          • 2. Re: Intel IoT (Edison) Eclipse C++ Build Error in Release Mode

            Just run the binary directly on the board. Either in a terminal within Eclipse as described on https://software.intel.com/en-us/blogs/2014/09/23/intel-iot-devkit-remote-access-through-ide (you would have to start as "nohup <sw>&" if you want to close Eclipse) or directly from a terminal


            @CMata_Intel I guess you wanted to refer to Internet of Things rather than to XDK forum?

              Could you pls give me some more detailed information to overcome my difficulty? I read all the forums that you refered (XDK and IoT) but it is impossible to find any satisfying answer. I know that the codes run on edison with a remote connection. During Run process the compiled codes transfer into /tmp folder on Edison. But without eclipse how should I use gcc or similar command on edison?  If i try to use "gcc filename" I get lots of error each time.  Regards.

                That sounds different to me than your initial question.

                You understood you were asking on how to run binaries generated by Eclipse outside of it.

                That's what I answered.

                Now you seem to ask how to compile on the target. Could you please clarify what you are up for?

                  I use gcc all of the time directly on the Edison.  I use PuTTY on a PC to create a terminal window, I use WinSCP to transfer files from my machine to the Edison.  Alternatively I also use the git commands to download stuff from place like github.com.


                  Note:  many of my makefiles get sort-of convoluted as I run them on several different platforms, but as an example here is one that I have been playing with this week for testing out a Ping sensor using MRAA.


                  In a directory I have the source file, in this case testMraaPing.cpp, which has:  Warning, this is a test program that started out for a different device and I just hack on it enough to try out MRAA with a ping sensor.

                  Again sorry that these files are a lot more complex than what is needed, But my makefiles have changed/convoluted over time.  I have them setup to do some dependency checking, builds...  Also most of mine have stuff in them that detect which platform it is running on and change some of the settings, like where the compiler is, or what include directories to use...


                  Again sorry if this is not the type of thing you are looking for.



                  • 6. Re: Intel IoT (Edison) Eclipse C++ Build Error in Release Mode

                    I have two main issues which are related to eachother.

                    1st one: I can run sample codes as the same way that explained in the guideline but the codes run only while eclipse ide is opened. When I exit from eclipse the project stops working on edison. The answer is ok, I should run the codes inside the edison with a remote connection.

                    2nd one: I can see the files which are compiled by eclipse inside the /tmp folder on edison. But I'm not sure what should I do as the next step. So I'm asking for your help. I tried gcc command in different ways with a putty connection but each time I get lots of error messages.


                    If anyone can share a link or some documents that explains the procedure briefly and step by step that should be followed, I would be appreciated.


                    • 8. Re: Intel IoT Eclipse C++ Build and Run Problem on Edison

                      In the setting of eclipse's Run configurations,you have set the path to remote create the excutable  file, and the command to set the properties of the file. When you disconnect the Edison without eclipse remote method. You can use the putty or something else tools to connect the Edison. And directly excute the excutable files you create.
