I am trying to get the Yocto Eclipse plug-in setup so that I can build my application from Eclipse. I am *almost* there, but the final build is not working. I'm assuming there are some path/rights issues somewhere in the chain because I can build from the command line. I'm looking for some help in figuring out where the difference is.
I am using Fedora 21 64-bit for a host system. I am using Eclipse Kepler; I also have Eclipse Luna installed, but I had to install Eclipse Kepler since another plugin I am using does not yet have support for Eclipse Luna. I am on poky/daisy HEAD and have been able successfully build my image (image based on core-image-minimal with a few extra applications). Under Eclipse Kepler, I installed the pre-build plug-in from the Yocto Eclipse Update Site as instructed in the Yocto Project Development Manual for Poky 1.6.2. I am using my existing toolchain in the build directory, so I issued "bitbake meta-ide-support" to generate the cross-toolchain support. I then followed the instructions under "Extracting the Root Filesystem" in the ADT Manual to extract the root filesystem. Specifically, I sourced the newly created environment script and then called "runqemu-extract-sdk <my_built_image.tar.gz> <sysroot_destination_directory>". Then, from Eclipse I setup the Yocto Project ADT for a "Build System Derived Toolchain", I set the Toolchain Root Directory to my Poky build directory, and I set the Sysroot location to my extracted sysroot directory.
After the initial environment setup, from Eclipse I selected File->New->C Project, and selected a "Hello World ANSI C Autotools Project" under the "Yocto Project ADT Autotools Project" options. For the new project, if I select "Reconfigure Project" the configuration fails with the following error:
checking whether the C compiler works... no
From checking config.log, here are the details on the build failure:

Note that <home_path> included the actual path to my home directory in config.log but I changed it to <home_path> for the purposes of this e-mail (yes, I'm paranoid).
However, if I instead open a terminal, go to my project directory and do the following:
source <path_to_Poky_build_directory>/environment-setup-arm926ejste-poky-linux-gnueabi
./configure ${CONFIGURE_FLAGS}
The project configures without a problem. I can then either build from the command line or I can build from Eclipse. It seems very odd to me that the configure doesn't work from Eclipse, but once it is configured I can build without issue. Anyone have any ideas as to what I have wrong in my setup?
Thanks,
Bryan

It appears that your toolchain is configured properly, however the GNU
linker (ld) cannot find the libraries it needs to link the binary.
I suspect that the culprit is "--sysroot=$SDKTARGETSYSROOT"
There should be an environment setup file
/<home_path>/poky/poky-build/tmp/environment-setup-XX
If you open it you will see SDKTARGETSYSROOT environment variable. It
most likely points to a different sysroot path. Please change it to
point to the directory where you extracted your sysroot
(/<home_path>/extracted_sysroot_1.6.2), create a new project and see if
that builds OK.

This builds, but it most likely uses the rootfs bundled in the
poky-build directory as pointed to by SDKTARGETSYSROOT and not the
rootfs which your extracted.

I've been having a few other issues with Eclipse (Install New Software menu item disappearing, other plugins disappearing after restarting, etc.), so I uninstalled eclipse, deleted my ~/.eclipse and workspace directories and re-installed Eclipse. I need to run Eclipse Kepler (another plugin I'm using isn't ready for Eclipse Luna), so I followed these instructions for installing Eclipse by hand: http://www.92wiki.com/en/blog/detail/install-eclipse-kepler-on-fedora-17-18-19-centos-red-hat-rhel-5-6. I also edited my environment setup script as suggested. I then reinstalled all necessary plugins as described in the ADT manual. I pointed the toolchain to my build directory and the sysroot location to my extracted sysroot. I then followed the steps in the ADT manual to create a new Hello World Yocto ADT project. I verified the SDKTARGETSYSROOT environment variable in the new project points to my extracted sysroot. When I attempted to build, I get the following output:

Configuration failed with error
The bold lines are ones that I see as a potential problem. First, the system couldn't find aclocal in my extracted sysroot. I took a look in the directory listed, and aclocal is not in there. I think the configure script also found the build system's install and mkdir (/usr/bin/install and /usr/bin/mkdir). I don't know if there is supposed to be one of these in the extracted sysroot or not, but I thought it was worth noting.
On a possibly related topic, I noticed that the Eclipse Indexer is using the build system's header files. For example, if I open the main source file from the Hellow World application, place my cursor on the line "#include <stdlib.h>" and hit F3, /usr/include/stdlib.h opens up instead of stdlib.h from my toolchain. Under the Eclipse project, for the listed Includes directories it has the following:
/usr/include
/usr/lib/gcc/x86_64-redhat-linux/4.9.2/include
/usr/local/include
Any thoughts on how to fix these issues?
Thanks,
Bryan

This is a different error. There seems to be a mismatch between your
toolchain and rootfs. Could you please share the full name of
my_built_image.tar.gz from
runqemu-extract-sdk <my_built_image.tar.gz>

Eclipse is showing the host headers, but it will use the headers from
your sysroot during the actual build.

It's the root filesystem that I built and runs on our target hardware. It's based on core-image-minimal with a few additional packages. Are there some additional (or some specific) packages that are needed for it to be a suitable rootfs for this purpose?

I have been able to get things to build, but not exactly in a suggested manner. I copied the entire target sysroot directory (~/poky/poky_build/tmp/sysroots/at91sam9x5ek) to the previously mentioned sysroot destination directory. I re-ran "bitbake meta-ide-support" just to ensure I had a clean copy. I then modified the SDKTARGETSYSROOT to point to my copied sysroot location. With this setup, I was able to get the project to build from Eclipse. It's working, but it's a little ugly getting there.
So I'm assuming I'm starting at the wrong point for the sysroot to extract. What do other people do?

You have two options here:
1) Generate a standalone toolchain and sdk installer.
bitbake -c populate_sdk your_image_name
This will generate an installer script-tarball in
~/poky/poky_build/tmp/deploy/sdk/
Execute this script and follow the installation instructions. This will
extract both the toolchain and sysroot to a directory of your choice
(e.g. /opt/poky/1.6.2/).
When you configure the Yocto ADT plugin in Eclipse, select "Standalone
pre-built toolchain" before you point it to the sysroot and toolchain
directories created by the installer above.
2) Base your image on one of the development images (e.g.
core-image-minimal-dev)
Cheers,
Todor

So *that* explains why I've never been able to get the Eclipse plug-in to work. I'd suggest adding the above detail to the "Extracting a Root Filesystem" section of the manual.
For a frame of reference, I do two separate actions. I'll use bitbake to build our full production image. We also have a few userspace applications in which I'll build through Eclipse and test on the actual hardware. We interface with enough external devices that testing with the QEMU doesn't work too well and we'll need to test on actual hardware. So I just need to build something that I can then run on the actual hardware. After re-reading the "Extracting the Root Filesystem" section, I think there is an assumption that someone would only be doing this for QEMU purposes. I think some details stating what is needed out of the extracted filesystem for development would be beneficial.
Thanks,
Bryan
