I have been trying to get a 32-bit compile of ros working on a 64-bit machine, and I'm having a problem with one library. I get the following: /usr/bin/ld: skipping incompatible /home/arm_user/darpa_arm_software_x86/ros/tools/rospack/lib/librosstack.so when searching for -lrosstack /usr/bin/ld: cannot find -lrosstack This implies that for some reason rosstack is not re-compiling with my modified -m32 flag (in the ros cmake config files.) Is there any reason that rosstack would be compiling without the default flags? Thanks, Jeff Hyams RE2, Inc. www.resquared.com
