Revision history [back]

Hi Ruben,

Thank you for your answer. I use the last version of boost : 1.46.1. I can't get to another version with macport since I just installed it.

I compiled with verbose and here is the result :

mkdir -p bin
  cd build && cmake -Wdev -DCMAKE_TOOLCHAIN_FILE=`rospack find rosbuild`/rostoolchain.cmake  ..

I hope that can help you.
