No, it's not useful. My .theanorc file is
[global]
floatx = float32
cxx = C:\Users\Song\Miniconda3\Library\mingw-w64\bin\g++.exe
mode = FAST_RUN
device = cuda
[blas]
ldflags = -LC:\Users\Song\Miniconda3\Library\bin -lmkl_rt

root = C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0
[nvcc]
flags=--cl-version=2015
[dnn]
enabled=True
[lib]

the error is:
