Hello,

I can't link against the filesystem library.
When I try to compile a program using boost::filesystem (like the simple
one attached to this email), I get "undefined reference" errors from the
linker:

dourak_at_Vvardenfell:~$ g++ -o dummy dummy.cpp -lboost_filesystem
-lboost_system
/tmp/ccMpl6cj.o: In function
`boost::filesystem::exists(boost::filesystem::path const&)':

const&)]+0x19): undefined reference to

undefined reference to `boost::filesystem::path::codecvt()'

I carefully sorted the libraries in the command line, since gcc has trouble
with library dependencies, sometimes, but it still doesn't work.
I use gcc 4.6.3 on Ubuntu 12.04 64bits. The problem occurs either with
boost 1.46.1 (taken from the repositories) or with 1.50.0 (installed with
bjam).

Any hint ?
