Qt creator with CUDA show Semantic Issue

kubikula

Hi,
I try to compile simple CUDA code with qt creator.
In .pro file I use this code

...
SOURCES += \
        main.cpp

CUDA_DIR = /usr/local/cuda-10.0
CUDA_SOURCES +=  cuda_functions.cu
CUDA_ARCH = sm_53
NVCC_OPTIONS = --use_fast_math
HOST_COMPILER=$$QMAKE_CXX
LIB_PATH=x86_64-linux

equals(HOST_COMPILER, "aarch64-linux-gnu-g++") {
    LIB_PATH=aarch64-linux
}

INCLUDEPATH += $$CUDA_DIR/targets/$$LIB_PATH/include
QMAKE_LIBDIR += $$CUDA_DIR/targets/$$LIB_PATH/lib
LIBS += -L $$CUDA_DIR/targets/$$LIB_PATH/lib -lcudart -lcuda

CONFIG(debug, debug|release) { #debug
    cuda_d.commands = $$CUDA_DIR/bin/nvcc -ccbin $$HOST_COMPILER -D_DEBUG $$NVCC_OPTIONS -m64  -arch=$$CUDA_ARCH -c -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
    cuda_d.dependency_type = TYPE_C
    cuda_d.input = CUDA_SOURCES
    cuda_d.output = cuda/${QMAKE_FILE_BASE}.o
    QMAKE_EXTRA_COMPILERS += cuda_d
} else { #release
    cuda.commands = $$CUDA_DIR/bin/nvcc -ccbin $$HOST_COMPILER $$NVCC_OPTIONS -m64 -arch=$$CUDA_ARCH -c -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
    cuda.dependency_type = TYPE_C
    cuda.input = CUDA_SOURCES
    cuda.output = cuda/${QMAKE_FILE_BASE}.o
    QMAKE_EXTRA_COMPILERS += cuda
}
...

Everything works fine, so I can compile and run the code.
But Qt creator show me semantic issue (see in the picture):

use of undeclared identifier blockDim, blockIdx and threadIdx

although the compile was successful.

It looks like indexer or I don't know issues.
Please can you help me how to remove this "cometics" problem.
Thank you

Hi @kubikula,

most likely the Code Model has problems parsing a header file.

Where do these definitions actually come from? Are there more errors when you open the header file containing these definitions?

Hi,

AFAIR, these come directly from CUDA. Therefore I am not sure that the clang code model is ready for CUDA kernel code.
