Cuda linking static libraries using cmake

Accelerated Computing CUDA CUDA Programming and Performance
1

Hi,

I need to link cuda nppi static library (libnppi_static.a) to my runtime of the code. Currently I’m using the shared libraries but when linked to static library it’s very fast, which I have experienced in Nsight editor. But I’m developing this in Ubuntu 14.04, cuda 7.0 and cmake.

I have attached my CmakeLists.txt herewith.

cmake_minimum_required(VERSION 2.8)

project(libSGM)

find_package(CUDA REQUIRED)
#set(CUDA_ARCH "arch=compute_50,code=sm_50" CACHE STRING "Value of the NVCC -arch option.")
set(CUDA_ARCH "-arch=sm_50" CACHE STRING "Value of the NVCC -arch option.")
SET(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} ${CUDA_ARCH}")
#option(CUDA_USE_STATIC_CUDA_RUNTIME "Use the static version of the CUDA runtime library if available" ON)

find_package(OpenCV REQUIRED core) 
if(OpenCV_VERSION VERSION_LESS 3.0) 
	find_package(OpenCV REQUIRED core highgui imgproc)  # 2.x
else()
	find_package(OpenCV REQUIRED core highgui imgproc imgcodecs videoio calib3d objdetect photo) # 3.x
endif()

include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(include)

SET(STEREOSRCS 
	src/census.cu 
	src/matching_cost.cu 
	src/scan_scost.cu 
	src/winner_takes_all.cu 
	src/median_filter.cu 
	src/check_consistency.cu 
	src/cuda_utils.cu
)

CUDA_ADD_LIBRARY(sgm src/stereo_sgm.cpp ${STEREOSRCS} STATIC)

CUDA_ADD_EXECUTABLE(stereo_test src/stereosgm_image.cpp ${CUDA_SRC})

TARGET_LINK_LIBRARIES(stereo_test sgm ${CUDA_LIBRARIES} ${CUDA_nppi_LIBRARY} ${OpenCV_LIBS})

I have tried so many options to change the CmakeLists.txt to link to static nppi library.

It is very much appreciated if you can help me out of this situation.

I’m confused, is there an issue even being raised here? Is CMake not liking your CMakeLists.txt?

Hi,
I can link to the shared libraries. But do not know a way to link to static nppi libraries. That’s the issue.
Thanks

check your CUDA_nppi_LIBRARY value, see what’s inside.
