I'm trying to use the Yocto Project Eclipse ADT plugin using the manual as a reference with a standalone pre-built toolchain created by running bitbake <recipename> -c populate_sdk, then running poky-glibc-x86_64-<recipename>-x86-toolchain-2.0.sh, specifying default locations. I've sourced the environment-setup in opt/poky/2.0. My Toolchain Root Location is pointing to /opt/poky/2.0 and my sysroot is pointing at /opt/poky/2.0/sysroots/x86-poky-linux.
I was able to compile a "Hello, world" program using this enviromnent, but with a larger project I hit errors during the Build Project step.
Here's the relevant part of my config.log:

If you meant to cross compile, use `--host'.
I think the most important line of this might be:
/home/presslertj/workspace/HMM/configure: ./conftest: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
Which looks to me like it's looking in the wrong place for ld-linux.so.2. Also, when running build, Eclipse's terminal spits out the following lines:
ENV key HOST_CC_ARCH is NULL
ENV key TOOLCHAIN_OPTIONS is NULL
ENV key SELECTED_OPTIMIZATION is NULL
ENV key TARGET_ARCH is NULL
ENV key OECMAKE_C_LINK_FLAGS is NULL
ENV key OECMAKE_CXX_LINK_FLAGS is NULL
ENV key STAGING_DIR_HOST is NULL
ENV key STAGING_DIR_NATIVE is NULL
ENV key CROSS_DIR is NULL
ENV key OECMAKE_EXTRA_ROOT_PATH is NULL
ENV key EXTERNAL_TOOLCHAIN is NULL
ENV key STAGING_DATADIR is NULL
I'm guessing that one of these variables needs to be specified so that ld-linux.so.2 is found but I don't know which, and I feel like I might've missed some critical step. What is causing this error? Have I misconfigured my environment?
As read in How to fix /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory:
This will happen only on 64 bit systems, the cause is the fact that 32 bit libraries are missing from the system, so you can easily fix this issue by installing the 32 bit libraries on your system.
So if you encounter this error /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory this is how you can fix it:
To fix it:
On any RPM based distribution (CentOS/RedHat/Fedora/Suse/Mandriva):
yum -y install glibc.i686On any DEB based distribution (Debian/Ubuntu/Mint/Crunchbang):
apt-get update apt-get install ia32-libs
