I am new to building boost, so I apologize if this is an uninformed question. I was able to build the boost 1.49 and 1.50 libraries using qcc 4.4.2 (QNX’s gcc 4.4.2) without major issues. Boost 1.51 has added a new wrinkle, and I’m not sure how to address it. Here’s a snipit from the build.log. Any help is appreciated.
