I am trying to link a project to boost:filesystem on Ubuntu 13.04 and I am geting some weird linking errors in the last stage.
The build configuration is done via cmake:
find_package(Boost COMPONENTS system filesystem program_options REQUIRED )
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})
target_link_libraries(${YARS_TARGET} yarsLib GLEW GL GLU glut m dl xerces-c ode ${Boost_LIBRARIES})
I tried using a different boost version. For 1.49 and 1.53 I have the same behaviour. On Ubuntu 12.04 it does work just dine and on my development machine running Archlinux with boost 1.53 it compiles, links and runs just fine.

Just a suggestion:
1)Check that your boost library contains required symbols, you can use something like this: nm -D /usr/lib64/libboost_filesystem.so.1.52.0 | grep detail | c++filt | grep your names
2)Try to change order of linking library, for example put -lboost_bla-bla-bla to the end of command line, and run this command with g++ again, not use make or something, just copy paste command and make experiments with it.
I was facing errors like:
Other solutions did not work. I wrote this in my cpp file:
And the problem went away. I guess, it was not able to include it automatically. I also tried with v2, but that did not work, I had to do v3.
