A few days ago I asked if anyone knew of an RPM for activemq-cpp that could be installed on Centos 5. It was suggested that I might find one in the newer Fedora repositories. Indeed I did, but there were several dependencies on newer libraries, so I had to resort to compiling it myself. Typically this is not such a big deal, but it was tricky because I needed the 32 bit build and I was compiling on a 64 bit Centos 5.
I finally got it done and posted the recipe for cross-compiling activemq-cpp on Centos 5. If anyone needs to do the same, check here for the steps: http://devinvenable.blogspot.com/2010/07/cross-compile-activemq-cpp-on-centos-5.html Devin
