Some days ago I compiled Boost ver. 1.53.0 for VS2012. It works fine, compiles fine. Now I want to use Boost with Qt Creator. In the .pro file I've included
INCLUDEPATH += C:\boost\boost_1_53_0\ -lboost_filesystem
LIBS += C:/boost/boost_1_53_0/stage/lib/
But when I compile I get 2 errors:
:-1: error: cannot find C:/boost/boost_1_53_0/stage/lib/: Permission denied
collect2.exe:-1: error: error: ld returned 1 exit status
What should I do? I've googled but seems I'm the first with this error.

If the library name ends in d, deselect the Remove "d" suffix for release version option. Qt Creator supports code completion and syntax highlighting for the added libraries once your project successfully builds and links to them. In the Projects view, right-click the project name to open the context menu and select Add Library.
I don't use boost as much as I could, often I already have an alternative in Qt (filesystem e.g.). Where boost really comes to shine is, that it is essentially a toolbox, full of helpful little libraries, plus a few big libraries handling things like parsing, filesystem, sockets, threading or GPU computing.
There is now the boost incubator, making it easier to submit libraries to boost. There is a new generation of boost libraries build with C++11 and C++14, though boost probably will have a few legacy libraries, which will or already have found their replacements. For example boost::tmp -> boost::hana.
You can use pkg-config to query system libraries during compilation. For your own libraries and 3rd party libraries, you need to specify the paths. Qt Creator tries to guess the include path for an external library, but you need to check it and modify it if necessary.
INCLUDEPATH += C:\boost\boost_1_53_0\ -lboost_filesystem
LIBS += C:/boost/boost_1_53_0/stage/lib/
Wrong.
Read this.
Solution:
INCLUDEPATH += C:/boost/boost_1_53_0/
LIBS += "-LC:/boost/boost_1_53_0/stage/lib/"
Boost has complicated library names ("libboost_filesystem-vc90-mt-1_53.lib") and in case of msvc it links them automatically.) If you want to link additional lib, you do it like this:
LIBS += "-LMyLibraryPath" -lmylib
Where MyLibraryPath is library path, and mylib is library you want to link with.
i'm the first with this error.
The error most likely occurs because compiler tries to open directory as if it were a file or something like that.
