Add Cuda libs to QT
-
Hello,
I found in web many examples how to link NVIDIA CUDA to QtProject (Mingw or MSVC 64 bit), but none work correctly for me. Maybe someone know how to do this?

My last: .pro file looks like that:
QT += core QT -= gui TARGET = QtCuda CONFIG += console CONFIG -= app_bundle TEMPLATE = app SOURCES += main.cpp \ cuda_code.cu # project build directories DESTDIR = $$PWD OBJECTS_DIR = $$DESTDIR/obj # C++ flags QMAKE_CXXFLAGS_RELEASE =-O3 # Cuda sources CUDA_SOURCES += cuda_code.cu # Path to cuda toolkit installb C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\lib\x64 CUDA_DIR = "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v7.5" # Path to header and libs files INCLUDEPATH += $$CUDA_DIR/include QMAKE_LIBDIR += $$CUDA_DIR/lib/x64 SYSTEM_TYPE = 64 # '32' or '64', depending on your system # libs used in your code LIBS += -lcuda -lcudart # GPU architecture CUDA_ARCH = sm_50 # Here are some NVCC flags I've always used by default.
