libboost_regex missing link to libicuuc in openSUSE

[teddybouch@…]

I am running openSUSE 12.3, which installs with Boost v1.49 and just used YaST to update Boost to v1.53 along with a number of associated libraries. 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.

I just built regex on Ubuntu and the ICU libraries are definitely linked in there. I suspect that whoever packaged the binaries for that platform messed up - especially as it worked for 1.49, and I don't recall any significant changes to our build scripts. Suggest you file a bug report with Suse - sorry to pass the buck :-(

Possible workarounds would be to:

• Rebuild the regex binaries from source.
• Or temporarily rename the regex .so files, so your application is forced to link against the static .a library.

Thanks very much for looking into it. I'll pass it along to the openSUSE community.
