But when I go to install ROS, which uses libboost_regex, I get a series of errors that all look like the following: /usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../lib64/libboost_regex-mt.so: undefined reference to `u_tolower_51' After talking with someone on the Boost IRC channel who was very helpful, I was able to use readelf to look at the Version needs section of libboost_regex.so.1.53.0 and determine that libicuuc.so is not linked, which provides those missing references. I wish that I could offer a fix, but I'm way out of my depth here. If someone could please fix this linking issue and let me know how to do so on my system, I would greatly appreciate it. Thanks very much." Bugs closed To Be Determined regex Boost 1.53.0 Problem worksforme opensuse ROS
