Hi Tanassis,
Can you install your sysroot setup by following the steps of ADT manual, either download a prebuild image.tar.gz file and use runqemu-extract-sdk to extract it under /home/user/sysroot_*** directory, or use adt_installer to set it up? Any of the sysroot that you got by building toolchain is just too minimum and we typically advise people to setup their sysroot base on target image rootfs.

The target showed up correctly in the dropdown box ( armv7a-vfp-neon-poky-linux-gnueabi ) . Following your advice, I changed the toolchain and sysroots to point to /opt/poky/1.4.1/ (changed the radio button to point to "standalone prebuilt toolchain" - i bitbaked from the same build the meta-toolchain-sdk as well. I then recreated the hello world autotools example and the problem persists..... Thank you for your help!

I noticed from the commandling that your sysroot is sysroot=/home/nass/yocto/build/tmp/sysroots/imx6qsabrelite Typically we'd advise people not to directly use the sysroot under the build environment. If you follow the ADT manual there're couple ways for you to setup sysroot, either extract from image rootfs or use adt_installer.

I am stuck in section 4.2.2.2 trying to make a simple autotools hello world application. The build fails at configure stage checking for style of include used by make... GNU checking for arm-poky-linux-gnueabi-gcc... arm-poky-linux-gnueabi-gcc -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon --sysroot=/home/nass/yocto/build/tmp/sysroots/imx6qsabrelite checking whether the C compiler works... no configure: error: in `/home/nass/eclipse/adt_hello/': configure: error: in `/home/nass/eclipse/adt_hello/': configure: error: C compiler cannot create executables configure: error: C compiler cannot create executables See `config.log' for more details Configuration failed with error config.log looks fairly similar to this post: https://lists.yoctoproject.org/pipermail/yocto/2013-January/013860.html I have configured to use the toolchain from the build directory. In fact the paths to the toolchain and sysroots are (both): "/home/nass/yocto/build/tmp/" . I went on to try the slightly more manual in CLI : http://www.yoctoproject.org/docs/1.4/adt-manual/adt-manual.html#creating-and-running-a-project-based-on-gnu-autotools again at configure stage, I get: checking for gcc... arm-poky-linux-gnueabi-gcc -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon --sysroot=/home/nass/yocto/build/tmp/sysroots/imx6qsabrelite checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... configure: error: in `/home/nass/appz/dev/yoctauto': configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details Should I really use --host? Wouldn't it be in the plugin setup options already if that was necessary? OR wouldn't the environment-setup* file contain the necessary declarations? Any ideas how to avert it? Thank you for your help!
