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?
