Hi All,
I am trying to run boost1.34.1 in  ubuntu 7.10.
Compiling the program like this

 g++ -o fst boostThread.cpp -lboost_filesystem

throws error like bellow.

/usr/bin/ld: cannot find -lboost_filesystem
collect2: ld returned 1 exit status

Can any one please tell me how to get rid of this.

g++ can't find shared library libboost_filesystem.so

Provide the path to the library using -L option.
For example
g++ -o fst boostThread.cpp -lboost_filesystem -L/usr/local/boost-1.34.1/lib

If you don't know where library located try the following commands:
sudo updatedb
locate libboost_filesystem.so

On my system this command produces this output:
krivenok@develop2 10:44:55 ~/dev_builds/boost-trunk/boost/date_time $ locate libboost_filesystem.so
/usr/local/old_dev/boost-1.34.1/lib/libboost_filesystem.so
/usr/local/dev/boost-1.37.0/lib/libboost_filesystem.so
/usr/lib/libboost_filesystem.so
