CUDA 5.0 separate compilation of library with cmake

Question

The buildtime of my cuda library is increasing and so I thought that separate compilation introduced in CUDA 5.0 might help me. I couldn\'t figure out how to achieve separat

Answer 1

Tested it with nvcc version:

nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2012 NVIDIA
Corporation Built on Fri_Sep_21_17:28:58_PDT_2012 Cuda compilation
tools, release 5.0, V0.2.1221

and svn revision:

In this example includes following classes:

• lib.h / lib.cu
• kernel.h / kernel.cu

kernel.cu contains a simple CUDA kernel and a class with a public method to call the CUDA kernel. The class lib contains an instance of the class kernel and a method calling the public method of class kernel.

Following CMakeLists.txt works with this configuration:

cmake_minimum_required(VERSION 2.6.2)

project(Cuda-project)

set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/CMake/cuda" ${CMAKE_MODULE_PATH})

find_package(CUDA QUIET REQUIRED)

set(CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE OFF)

set(BUILD_SHARED_LIBS ON)

list(APPEND CUDA_NVCC_FLAGS -DBLAH="he he" -DTEST1="this is a test")

CUDA_ADD_LIBRARY(test_lib
  kernel.cu
  lib.cu
  # SHARED
  # STATIC
  OPTIONS -DSTUFF="blah blah"
  RELEASE --use_fast_math -DNDEBUG
  DEBUG -g -DDEBUG
  )


INSTALL(FILES lib.h kernel.h
  DESTINATION include)
INSTALL(FILES "${CMAKE_BINARY_DIR}/libtest_lib.so" 
  DESTINATION lib)
