Is condition variable in a different library?
I'm having an identical problem on Ubuntu Karmic with the Boost 1.40 libraries.

My code (test.cpp) is:

#include <boost/thread/thread.hpp>
int main() {
  boost::condition_variable myCond;
  myCond.notify_one();
  return 0;
}

I compile with:
g++ -lboost_thread-mt test.cpp -o test

And get the error:
/tmp/ccj08TQK.o: In function `main': boost.cpp:(.text+0x2b):
undefined reference to `boost::condition_variable::notify_one()'
collect2: ld returned 1 exit status

Any suggestions?
