Qt & Boost not going along

[RaJiska]

Hello' People,

I've been trying to run Boost with Qt & Mingw but could not get them both along.
After linking the library (using filesystem), I get the following errors:

cannot find -lboost_system
cannot find -llboost_filesystem
error: ld returned 1 exit status

In my .pro file I've linked Boost as follow:

INCLUDEPATH += N:/Libraries/boost_1_60_0

LIBS += -L"N:/Libraries/boost_1_60_0/stage/lib"
LIBS += "N:/Libraries/boost_1_60_0/stage/lib/libboost_filesystem-mgw47-mt-1_60.a"
LIBS += "N:/Libraries/boost_1_60_0/stage/lib/libboost_system-mgw47-mt-1_60.a"

LIBS += -lboost_system -lboost_filesystem

To that, I made sure Qt & Boost compiled under the same MinGW compiler version (both using CodeBlocks').

Is there something I did not do properly ?

Thanks !
