Hi, atvreddy
Thanks for your reply. Did you use meta-clanton_v0.7.5 or meta-clanton_v1.0.1 ? Last year I had successfully built the Galileo Linux image and cross compiler using the meta-clanton_v0.7.5 by following the old guide Quark_BSPBuildGuide_329687_001.pdf on a 64bit Ubuntu 12.04 system.
But now I'm using the new BSP package meta-clanton_v1.0.1 and a new machine(Ubuntu 12.04 32bit) and following the new guide Quark_BSP_BuildandSWUserGuide_329687_006.pdf. I have tried to type the command "bitbake image-full-galileo" for several times after build failed without deleting the 'yocto_build' folder. But the issues(autogen-native_5.12.bb) stays all the same. Later I'll try to delete the yocto_build folder and rebuild as you said. Thanks!
