【问题描述】：
我正在尝试使用 Yocto Project Eclipse ADT 插件，使用手册作为参考，通过运行 bitbake <recipename> -c populate_sdk 创建独立的预构建工具链，然后运行 poky-glibc-x86_64-<recipename>-x86-toolchain-2.0.sh，指定默认位置。我在opt/poky/2.0 中获取了环境设置。我的工具链根位置指向 /opt/poky/2.0，而我的 sysroot 指向 /opt/poky/2.0/sysroots/x86-poky-linux。
我能够使用这个环境编译一个“Hello, world”程序，但是对于一个更大的项目，我在构建项目步骤中遇到了错误。
这是我的 config.log 的相关部分：

If you meant to cross compile, use `--host'.
我认为其中最重要的一行可能是：
/home/presslertj/workspace/HMM/configure: ./conftest: /lib/ld-linux.so.2: 坏 ELF 解释器：没有这样的文件或目录
在我看来，它在寻找 ld-linux.so.2 的错误位置。 此外，在运行构建时，Eclipse 的终端会输出以下行：
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
我猜测需要指定其中一个变量才能找到 ld-linux.so.2，但我不知道是哪个，而且我觉得我可能错过了一些关键步骤。是什么导致了这个错误？我是否错误地配置了我的环境？

如果你
apt-get install ia32-libs怎么办？见于howtodoityourself.org/… -
我试过并解决了这个错误。我曾假设我应该使用预构建工具链的链接器/加载器，但我想我想多了。如果您将此作为答案，我会接受。
