i'm having some troubles compiling my work, i'm using ubuntu with g++! i get a lot of these messages:

undefined reference to `boost::filesystem3::directory_entry::m_get_status(boost::system::error_code*) const'
undefined reference to `boost::filesystem3::path::extension() const'
undefined reference to `boost::filesystem3::path::filename() const'
undefined reference to `boost::filesystem3::path::filename() const'

(etc...)

I've searched and found maaany answers but none of those work for me.

[...]

-lboost_system (/usr/lib/gcc/i686-linux-gnu/4.4.5/../../../../lib/libboost_system.so)
-lboost_filesystem (/usr/lib/gcc/i686-linux-gnu/4.4.5/../../../../lib/libboost_filesystem.so)

[...] (when linking it shows those two libraries, i'm guessing the error is related to the second one.

hax@lap:~$ locate libboost_filesystem.so

/usr/lib/libboost_filesystem.so.1.42.0
/usr/local/lib/libboost_filesystem.so
/usr/local/lib/libboost_filesystem.so.1.47.0

this is the related line on my makefile:

-L. -L../bncsutil/src/bncsutil/ -L../StormLib/stormlib/ -L../boost/lib/ -lbncsutil -lpthread -ldl -lz -lStorm -lmysqlclient_r -lboost_date_time -lboost_thread -lboost_system -lboost_filesystem  -Wl -t

I tried pointing with -L several different places where i saw filesystem.so was located but it didn't work!

Can anyone see the problem in those lines? if you need me to put some extra data i'll do it, i'm not seeing the problem :(

Thanks :)
