The lib is failed to link in Qt

I use Qt 4.10.0 in 64-bit windows 7. When I tried to compile my project, error occurs: :-1: error: LNK1104: cannot open file 'libboost_date_time-vc141-mt-x64-1_71.lib'

But I do have this line in my .pro file and I have checked that the lib file (32-bit) is in this folder

LIBS += -L"D:/EPS_projects/2018to2019/29_IOT_MDI/boost_1_71_0/libs" - 
llibboost_date_time-vc141-mt-x64-1_71 \

I use boost boost_1_71_0 in my project.

If you use the -l notation, due to the way that qmake tries to be platform independent, you only need to supply the library name, without the first 'lib'.

Thus try the following:

LIBS += \ 
  -L"D:/EPS_projects/2018to2019/29_IOT_MDI/boost_1_71_0/libs" \
  -lboost_date_time-vc141-mt-x64-1_71

PS: The indenting is just for readability, you can keep it in one line
