undefined reference to symbol 'ros::Time::now()' [closed]

edit

Hi,

I am migrating my ros (fuerte) package from ubuntu 10.04 to 12.04. Furthermore I am migrating from boost version 1.40.0 to 1.46.1. Since I am using the boost::filesystem libraries (v2) and I do not want to change the code (to boost::filesystem v3) I add to every inclusion of "boost/filesystem.hpp" the following macro: #define BOOST_FILESYSTEM_VERSION 2.

I get the following error:

Linking CXX executable ../bin/SimpleDemo
/usr/bin/ld: /opt/ros/fuerte/lib/libroscpp.so: undefined reference to symbol 'ros::Time::now()'
/usr/bin/ld: note: 'ros::Time::now()' is defined in DSO /opt/ros/fuerte/lib/librostime.so so try adding it to the linker command line
/opt/ros/fuerte/lib/librostime.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[2]: *** [../bin/SimpleDemo] Error 1
make[1]: *** [CMakeFiles/SimpleDemo.dir/all] Error 2
make: *** [all] Error 2

Since I am not an experienced programmer, I would like to know what could cause this problem.
