CUDA: Creating object with G++ linker and cuda object files

I compiled my normal cpp files to .o, and my cuda .cu files to .co

I want to link these so I can call the cuda stuff from my normal C++ file

Here is my linker command that Make is running:

g++ -I ../readers/ -I../writers -I../common/ -I /home/dcole/software/xerces-c-3.1.1/src -I /home/dcole/NVIDIA_GPU_Computing_SDK/C/common/inc/ -I /usr/local/cuda/include -O3 -fPIC -fopenmp -DFIX_PAULI -DFIX_YAMA -DUSING_CUDA -o YamaguchiGPU YamaguchiMain.o YamaguchiDecomp.o cuYamaguchi.co -L/usr/lib64/ ../../lib/IDT.a ../../l开发者_开发知识库ib/Linux/libxerces-c.a ../../lib/Linux/libfftw3f.a -lcurl -lidn -ldl -lssl -lm -lpthread -lcuda -L/usr/local/cuda/lib64/libcudart.so 

So I am definitly linking cuda, and cudart, but yet I get this:

cuYamaguchi.co: In function `__sti____cudaRegisterAll_46_tmpxft_00003190_00000000_4_cuYamaguchi_cpp1_ii_init_gpu()':
tmpxft_00003190_00000000-1_cuYamaguchi.cudafe1.cpp:(.text+0x1b4): undefined reference to `__cudaRegisterFatBinary'
tmpxft_00003190_00000000-1_cuYamaguchi.cudafe1.cpp:(.text+0x20f): undefined reference to `__cudaRegisterFunction'

---

The Cuda file is being linked without problems but it looks like you might have forgotten to define some necessary function (like cudaRegisterFatBinary).

---

Upgrading to gcc 4.7.0 or higher should fix this horrid linker issue.

I was using an absolute search path in the linker to _libcudart.so_. I changed the -L to point to just the folder, then added -libcudart so it would search the folder for that lib.
