2013-05-10 12:43:25 -0500	answered a question	SIGILL, Illegal instruction in libpcl_common.so.1.5.1 from costmap_2d I managed to hack-fix this for now. All i did was just rebuilding pcl from ros-gbp/pcl-fuerte-release.git on github(debian/fuerte/precise/pcl branch) on the machine it's running on and then simply replacing the libpcl files in /opt/ros/fuerte/lib with the ones i built. Not a clean fix as it interfers with the package manager, but it works for now and i hope that the next update fixes it. It looks like cmake checks for the SSE and other cpu capabilitys when it's configuring. So if the buildservers are capable of avx and other extensions, that'd explain how the instructions got in there.

2013-05-10 01:43:35 -0500	asked a question	SIGILL, Illegal instruction in libpcl_common.so.1.5.1 from costmap_2d Since our latest ros fuerte update in ubuntu precise, our navigation crashes. After investigating the issue, we found out that the problem is the costmap_2d node, which crahses with SIGILL, which mean that an illegal assembler instruction was called. We furhter investigated this, and found out, that it's a AVX instruction call in Eigen, called from libpcl in libpcl_common.so.1.5.1 Our ros is running on an intel atom, which does not support avx, so we can't use it anymore. We tried to build our own version without avx, but failed to find out how to build our own deb to replace the existing one. The avx instructions shouldn't be in there at all, as many CPUs don't support it. The problems started with the ros update on 2nd May.
