After SDK is generated, install it and source its environment-setup script. And if I invoke $CC (arm-poky-linux-gnueabi-gcc), using this SDK, sizeof (long) is 4 (long = int) However, if I look into $CONFIG_SITE's definition of ac_cv_sizeof_long, it is defined as '8'. I feel this is strange since if this cached configure data is for the target (and cross-compiling), this value should be 4, to match the above (arm-poky-linux-gnueabi-gcc) result. (I think this part of the cache is being copied from poky/meta/site/x86_64-linux, ) This is causing break if I build autotool based program using the SDK. 3) Analysis If I look into toolchain-scripts.bbclass, I can see toolchain_create_sdk_siteconfig is gathering site-config information from the following two lists: 1) TOOLCHAIN_CONFIGSITE_NOCACHE 2) TOOLCHAIN_NEED_CONFIGSITE_CACHE 2) Seems to be OK, since it is getting the sitefiles from the target files. However, 1) is gathering the sitefiles by calling siteinfo_get_files(). If I look into siteinfo_get_files(), it returns information on HOST_ARCH-HOST_OS pair (here, I think HOST_ARCH-HOST_OS is not that of my target machine but my x86_64 HOST) In fact, if I debug bitbake behavior, I can see following files are actually appended as TOOLCHAIN_CONFIGSITE_NOCACHE files. xxx/meta-oe/site/endian-little xxx/poky/meta/site/endian-little xxx/poky/meta/site/ix86_common xxx/poky/meta/site/common-linux xxx/poky/meta/site/common-glibc xxx/poky/meta/site/common I think for toolchain_create_sdk_siteconfig(), TARGET_ARCH-TARGET_OS pair should be used to generate this list.
