Question

我必须在我的项目中关注两个文件：

home/cuda_compilation_test/
    main.cpp
    libcudatest.cu
    cuda_compilation_test.pro

我正在使用QtCreator和qmake进行编译。但是，当我使用下面显示的项目文件构建项目时，我收到链接错误文件格式无法识别;作为链接描述文件处理。尽管如此，它仍然在调试目录中生成两个目标文件

home/build-cuda_compilation_test-Desktop-Debug/
    main.o
    libcudatest.o

我怎么能

检查，确实正确生成了目标文件并且
在主项目中包含单独编译的libcudatest.o

进一步参考，这是编译器输出

g++ -m64 -o cuda_compilation_test_2 libcudatest.o main.o    -L/usr/lib/x86_64-linux-gnu -L/usr/local/cuda/lib64 -lcudart -lcudatest -lQtGui -lQtCore -lpthread 
/usr/bin/ld:libcudatest.o: file format not recognized; treating as linker script
/usr/bin/ld:libcudatest.o:1: syntax error
collect2: error: ld returned 1 exit status
make: *** [cuda_compilation_test_2] Error 1
11:19:20: The process "/usr/bin/make" exited with code 2.

和项目文件：

TEMPLATE =

# Files
SOURCES += main.cpp

OTHER_FILES += libcudatest.cu

LIBS += -L/usr/local/cuda/lib64
LIBS += -lcudart -lcudatest

# CUDA path
CUDA_DIR = /usr/local/cuda
CUDA_CC = $$CUDA_DIR/bin/nvcc

# CUDA Setup
CUDA_SOURCES  = libcudatest.cu
NVCCINCLUDES +=
NVCCFLAGS     = --shared -arch sm_35 -Xcompiler -fPIC --ptxas-options=-v
INCLUDEPATH  +=
LIBS         +=


# Configuration of the Cuda compiler
# http://doc.qt.io/qt-4.8/qmake-environment-reference.html#customizing
CONFIG(debug, debug|release) {
    # Debug mode
    cuda_d.input = CUDA_SOURCES
    cuda_d.output = ${QMAKE_FILE_BASE}.o
    cuda_d.commands = $$CUDA_CC -D_DEBUG $$NVCCFLAGS $$NVCCINCLUDES $$LIBS -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
    cuda_d.dependency_type = TYPE_C
    QMAKE_EXTRA_COMPILERS += cuda_d
}
else {
# Release mode
    cuda.input = CUDA_SOURCES
    cuda.output = ${QMAKE_FILE_BASE}.o
    cuda.commands = $$CUDA_CC $$NVCCFLAGS $$NVCCINCLUDES $$LIBS -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
    cuda.dependency_type = TYPE_C
    QMAKE_EXTRA_COMPILERS += cuda
}

我正在尝试在linux上编译。

非常感谢您对此主题的任何帮助。

使用qmake使用nvcc和gcc编译CUDA代码时“无法识别文件格式”
