Hi, I tried to follow the steps from the official Yocto toolchain documentation as in : http://www.yoctoproject.org/docs/1.4.2/adt-manual/adt-manual.html#creating-and-running-a-project-based-on-gnu-autotools When I run the configure step, I get a warning : configure: WARNING: unrecognized options: --with-libtool-sysroot This shouldn't be so bad, but unfortunately, because of this warning, I get the following issue: when I try to run the generated binary, I get : /lib/ld-linux.so.3: No such file or directory So it's clear that because configure doesn't understand the libtool sysroot parameter, it won't link my executable to the appropriate library path. ld-linux.so.3 is indeed present under sysroots/lib. So if the --with-libtool-sysroot were understood, that would work perfectly. Has anyone any clue on this? I google the error but couldn't find any valuable information Regards Jay
