[英]Qt: CUDA with Qt OSX Yosemite “sed: illegal option — r” error
I am building a simple app with Qt creator, in which I want to utilise CPU and GPU computation to complete a task and then compare the execution time in m/s. 我正在使用Qt创建器构建一个简单的应用程序,其中我想利用CPU和GPU计算来完成任务,然后以m / s比较执行时间。
I have read numerous articles and have concluded that I need to separate NVCC and GCC compilers from one another to avoid conflict. 我已阅读了大量文章并得出结论,我需要将NVCC和GCC编译器彼此分开以避免冲突。 I followed this tutorial , making tweaks for my system, however when I compile I get a strange error:
我按照本教程 ,对我的系统进行了调整,但是当我编译时出现了一个奇怪的错误:
sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]
make: *** [gaussian_cuda.o] Error 1
14:42:46: The process "/usr/bin/make" exited with code 2.
The error is obviously being thrown from this line in my .pro
configuration: 在
.pro
配置中,这行显然是错误的:
2>&1 | sed -r \"s/\\(([0-9]+)\\)/:\\1/g\" 1>&2
I don't understand why this is an illegal operation, and when I try to remove this line my code breaks completely. 我不明白为什么这是一个非法操作,当我尝试删除此行时,我的代码完全中断。
Why is r
an illegal operation? 为什么
r
是非法操作?
EDIT Complete config code: 编辑完整的配置代码:
QT += core gui
QT += multimedia
QT += multimediawidgets
QT += concurrent
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = WebcamFilter
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp \
camerafeed.cpp \
HEADERS += mainwindow.h \
camerafeed.h
FORMS += mainwindow.ui
# CUDA Resources
CUDA_SOURCES += gaussian.cu
CUDA_DIR = /usr/local/cuda
# Path to header and lib files
INCLUDEPATH += $$CUDA_DIR/include
QMAKE_LIBDIR += $$CUDA_DIR/lib
# Libs used for source code
LIBS += -lcudart -lcuda
# GPU Architecture
CUDA_ARCH = sm_20
# Custom flags for nvcc
NVCCFLAGS = --compiler-options -fno-strict-aliasing -use_fast_math --ptxas-options=-v
# Prepare extra compiler configuration
CUDA_INC = $$join(INCLUDEPATH,' -I','-I',' ')
cuda.commands = $$CUDA_DIR/bin/nvcc -m64 -O3 -arch=$$CUDA_ARCH -c $$NVCCFLAGS \
$$CUDA_INC $$LIBS ${QMAKE_FILE_NAME} -o ${QMAKE_FILE_OUT} \
2>&1 | sed -r \"s/\\(([0-9]+)\\)/:\\1/g\" 1>&2
cuda.dependency_type = TYPE_C
cuda.depend_command = $$CUDA_DIR/bin/nvcc -O3 -M $$CUDA_INC $$NVCCFLAGS ${QMAKE_FILE_NAME}
cuda.input = CUDA_SOURCES
cuda.output = ${OBJECTS_DIR}${QMAKE_FILE_BASE}_cuda.o
# Tell Qt that we want add more stuff to the Makefile
QMAKE_EXTRA_COMPILERS += cuda
As Park Young-Bae suggested, Mac sed
is not equivalent to GNU sed
and therefore the flag: 正如Park Young-Bae所说,Mac
sed
不等同于GNU sed
,因此标志:
2>&1 | sed -r \"s/\\(([0-9]+)\\)/:\\1/g\" 1>&2
had to be amended to: 必须修改为:
2>&1 | sed -E \"s/\\(([0-9]+)\\)/:\\1/g\" 1>&2
This fixed the issue. 这解决了这个问题。
