Elena, Pre-built SDKs (e.g. generated by OE from meta-toolchain) are usually meant to be used on their own, outside of the normal bitbake flow of OpenEmbedded. Previously it was possible to still use them externally by setting TARGET_CPPFLAGS and TARGET_LDFLAGS, like you are saying. Unfortunately, with the mandated use of --sysroot in latest OE, all the toolchain components have to be inside our sysroot, which is STAGING_DIR... Please check external-toolchain-csl.bb and external-toolchain-angstrom.bb recipes in recipes/meta/ directory for specific pointers on how to copy/stage the necessary objects, libraries and headers. Plus, installing/staging them properly also solves packaging and allows proper rootfs image generation with deployed libc packages from external toolchain. -- Denys _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
