[SOLVED] Problem linking boost_filesystem on Mac OSX
mkae last edited by
I have tried to compile the "boost_filesystem example program":http://www.boost.org/doc/libs/1_51_0/libs/filesystem/example/tut4.cpp with the following qmake configuration
@QT -= core
QT -= gui
CONFIG += console
CONFIG -= app_bundle
INCLUDEPATH += /opt/macports-test
LIBS += -L/opt/macports-test/lib -lboost_filesystem
SOURCES += main.cpp
Compiling poses no problem, but LINKING DOES :-(
as one can see here:
@08:39:51: Running steps for project filesystem...

08:39:51: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project filesystem (target: Desktop)
When executing step 'Make'
The libraries are to be found where I tell qmake
$ ls -1 /opt/macports-test/lib/libboost_filesystem*
So, I wonder where my - presumable simple - mistake is hidden...
I am using boost 1.50.0 installed through "MacPorts":http://www.macports.org and the qt-creator 2.5.0 installed using the official dmg from Nokia.

It seems like you need to link to boost_system as well as boost_filesystem.

OMG, I'd have never found this myself. Thanks for the hint. Indeed, when I use
@LIBS += -L/opt/macports-test/lib -lboost_system -lboost_filesystem@
all works just fine. :)
