No, this is a valid combination.

The binaries are usually sufficient for standard builds.

BOOST_ALL_NO_LIB disables autolinking support. Autolinking support usually 
works fine on Windows. 
Please take a look at 
http://www.boost.org/doc/libs/1_56_0/more/getting_started/windows.html
for decoding the information in the library file name.
Please attach the complete linker output next time. Partial information is not 
helpfull at all.

Then you have different compiler settings. Please compare the generated 
commandline of Visual Studio and QtCreator. Both should use the same set of 
flags and link against the same libraries. If this fails, make a minimal test 
case of your QtCreator project. 

Yours,
