在MacOS X小牛上链接Cuda应用程序时出错

Question

我试图使用C++ 5.1.1和Cuda 6在MacOS X小牛上构建XCode \ Cuda应用程序。

在链接过程中，我收到以下错误：

Undefined symbols for architecture x86_64:
  "std::ios_base::Init::Init()", referenced from:
      ___cxx_global_var_init in bmp-read.cu.o
      ___cxx_global_var_init in encoder_nostream.cu.o
      ___cxx_global_var_init in encoder_stream.cu.o
      ___cxx_global_var_init in tier1.cu.o
  "std::ios_base::Init::~Init()", referenced from:
      ___cxx_global_var_init in bmp-read.cu.o
      ___cxx_global_var_init in encoder_nostream.cu.o
      ___cxx_global_var_init in encoder_stream.cu.o
      ___cxx_global_var_init in tier1.cu.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我尝试在可能的情况下使用libstdc++ (-lstdc++)选项，但没有任何结果。

下面是makefile的一部分：

NVCC       := $(CUDA_INSTALL_PATH)/bin/nvcc
CXX        := g++
CC         := gcc
LINK       := g++ -fPIC

# Includes

# Compiler-specific flags
NVCCFLAGS := -ccbin /usr/bin/clang -arch=sm_30 --compiler-options -Wall,-ansi,-Wno-extra-tokens -Xcompiler -stdlib=libstdc++
CXXFLAGS  := $(CXXWARN_FLAGS) -stdlib=libstdc++
CFLAGS    := $(CWARN_FLAGS) -stdlib=libstdc++

...

LIB       := -L$(CUDA_INSTALL_PATH)/lib -L$(LIBDIR) -L$(COMMONDIR)/lib/$(OSLOWER) 
LIB += -lstdc++$(LIBSUFFIX)

诀窍是把-stdlib=libstdc++传给链接器。

LINK := g++ -fPIC -stdlib=libstdc++
