[yocto] Cannot Compile Application in Eclipse IDE Juno

Tue Nov 13 16:23:59 PST 2012

Hi Sean,

I did the exact same step as you did and my helloworld project was able to build using the Yocto ADT cross toolchain and sysroot, please see the attached screenshot.  Btw, what project did you create?  I've created File->New->C Project, make sure extend "Yocto Project ADT Project" and select "Hello World ANSI C Autotools Project".  After your project is created, highlight it and under Project menu you should see "Change Yocto Project Settings" and verify that your toolchain and sysroot there is also correct, which it should since it by default inherit for your Preference settings.

Thanks,

Jessica

I left the conf file alone, and tried to build for ARM. Same result. Attached is the ADT setup and the compile error I am seeing.

   Hi Sean,

   If you use adt-installer then the sysroot will be setup for you. So you don't need to step 4 and 5.  BTW, you do need to take a look of adt-installer.conf file to ensure the sysroot location is what you'd expected and also, the image (core-image-sato-sdk) is the one that's going to be extracted as sysroot.  Also, for Eclipse, please make sure the toolchain and sysroot is matching what you've used adt-installer to set them to.

   Thanks,

   Jessica

   Jessica,

   Trying to follow two different documentations that reference each other and a video on an older ADT and Eclipse versions is a bit of a challenge to get things setup. I am testing different approaches on my own in order to get a better understanding of what is going on.

   So to be clear:

   1.       Download the ADT 1.3 installer

   2.       Extract the install, don't make any changes to the adt-install.conf file - just install the ARM

   3.       Run the ADT installer, which should install the tool chain

   4.       Download the core-image-sato-sdk 1.3 image

   5.       Use the runqemu-extract-sdk to extract to the sysroot defined by ADT installer

   6.       Open Eclipse and point to the defaults

   Is this correct?

   Hi Sean,

   ADT support all 4 architectures (x86, arm, ppc and mips).  By reading your steps on how did you set up your cross development environment, seems there's confusion there.  Can you stick with one method at the time so it's easier for us to help on resolving your issue?  Can you download the toolchain for 1.3 release and install your toolchain using it?  For 1.3 we made toolchain relocatable, so you should be able to install it to a meaningful place to you.

   After install your toolchain, can you download our 1.3 core-image-sato-sdk image and extract it using runqemu-extract-sdk and using the output directory as your sysroot in Eclipse.  And see whether you can build the helloworld sample program.  If everything works, that means your steps of setting up the cross-development environment is correct.  Then you can switch to your n450 image as sysroot and see whether there's problem.  If so, we have to debug that issue.

   Thanks,

   Jessica

   Is there a step I missed? Or is the ADT only for ARM at the moment?

   I am using Intel Atom n450, not ARM. I have built three images using atom-pc for the BSP and core-image-sato-dev, core-image-sato, and core-image-sato-sdk for the base images. All the images are in the build directory. Using Hob, I set the Build Toolchain for each build to be x86_64 in the Advanced configuration. The images build and run.

   To setup the application development environment

   1.       Used Bitbake adt-installer - the ADT installer was in the tmp/deploy/sdk folder. (I also downloaded the ADT and extracted the tarball with the same result.)

   2.       Extracted the ADT tarball.

   3.       Change the adt_intstaller.conf file to

   YOCTOADT_TARGETS="x86_64"

   QEMU and NFS are set to Y

   YOCTOADT_ROOTFS_x86_64="sato-sdk"

   YOCTOADT_TARGET_SYSROOT_IMAGE_ x86_64="sato-sdk"

   YOCTOADT_TARGET_SYSROOT_LOC_ x86_64="$HOME/Yocto1.3/test-yocto/x86_64"

   I commented out the other settings for the ARM.

   4.       Ran the ADT installer. It looks like the QEMU rootfs gets installed in the $HOME/Yocto1.3/test-yocto/x86_64. As a test I changed this out with the rootfs built from one of the images. In either case the issue was the same

   5.       Installed Eclipse JUNO

   6.       Setup the Eclipse plugins per instructions

   7.       Setup the ADT parameters to point to the Toolchain Root Location and Sysroot location. An error would occur if I don't get these right.

   8.       Created the applications and tried to compile with the errors.

   Am I supposed to bitbake meta-ide-support?

   ADT installs by default not only the toolchain, but also the sysroot (ADT have to be configured and installed by matching your target architecture). It asks you where to install the tooclhain, but the sysroot is installed by default in this location: YOCTOADT_TARGET_SYSROOT_LOC_arm="$HOME/test-yocto/arm".

   That parameter can be found in adt-installer/adt_installer.conf.

   Basically, to deploy an app to your target using Eclipse, you have to specify 3 parameters:

    "Toolchain Root Location", "Sysroot location" and configure the Target options.

   Use the "Toolchain Root Location" as location where you have installed the ADT, and the Sysroot Location as specified in the adt_installer.conf. ADT needs the first two params in order to build you app locally.

   "runqemu-extract-sdk" is used to extract the qemu tarball that can be used as sysroot location. More details about the ADT tools are found at the same location: http://www.yoctoproject.org/docs/current/adt-manual/adt-manual.html.

   Do I have to use Qemu? Can I use my target's rootfs?

   If I can use my target's rootfs, how do I extract the SDK? runqemu-extract-sdk?

   Hi Sean,

   There may be a problem with your sysroot setup. Please make sure you have set it correctly by following the tutorial from here: http://www.yoctoproject.org/docs/current/adt-manual/adt-manual.html#extracting-the-root-filesystem

   Yocto 1.3 Danny

   Target: n450 Black Sand

   Eclipse: Juno C/C++ Developers

   After going through the steps to setup the ADT and Eclipse plugin, I am trying to compile the Hello World application based on the Hello World ANSI C Autotools Project type. I think I have the ADT Preference set correctly. It is not complaining about a missing tool chain.

   Compiling results in errors:

   Compiler cannot create executable in /home/sean/workspace/HelloADT - Configuration problem

   Make *** No rules to make target 'all' - C/C++ problem

   What am I missing?

   Regards,

   Sean
