compile under linux

[GoogleCodeExporter]

I am trying to compile cuda-bgs in linux.
I have commented out 2-3 lines of code that used "conio.h" which is not 
portable.
If i try to compile with nvcc the main.cpp it says that it can not link the 
cuda functions.
If i rename it to main.cu i get the following error:
http://tech.groups.y...V/message/81513

Any Ideas how to overcome this?
If i comment out an include line in the cuFastBG..ver5.cu file i can do:
nvcc -c cuFastBG..ver5.cu and end up with an .o file .
Then i use the following command:
g++ CvFastBgGMM_ver5.o main.cpp -o loadimg -I"/usr/include/opencv" -lcxcore 
-lcv -lhighgui -lcuda -I"/usr/local/cuda/include" -L/usr/local/cuda/lib64 
-lcudart

but it produces:
main.cpp:(.text+0x105): undefined reference to `cvCreateFastBgGMMParams(int, 
int)'
main.cpp:(.text+0x127): undefined reference to 
`cvCreateFastBgGMM(CvFastBgGMMParams*, _IplImage*)'
main.cpp:(.text+0x162): undefined reference to 
`cvUpdateFastBgGMMTimer(CvFastBgGMM*, _IplImage*)'
main.cpp:(.text+0x2bc): undefined reference to 
`cvReleaseFastBgGMM(CvFastBgGMM**)'

if i try and compile main.cpp with g++ it succedes,if i compile the .cu file 
with nvcc it also succedes.
But if i try:
g++ main.o CvFastBgGMM_ver5.o -I"/usr/include/opencv" -lcxcore -lcv -lhighgui 
-lcuda -I"/usr/local/cuda/include" -L/usr/local/cuda/lib64 -lcudart
I get the exact same error.

Hi,

I don't know if you had solved this problem yet, But I guess if you are using 
version5 of your .cu code for GMM, you need to change your #define 
CUDAGMM_VERSION to 5 from 4 inside CvFastBgGMM.h because that is preventing the 
code from getting inside CvFastBgGMM_ver5.cu at the entry point. Also you might 
have to provide a template option of no. of blocks in line 171 and 180 of 
cudaUpdateFastBgGMM . This should solve the problem and help you compile it.

The problem has been solved and the program has now been successfully compiled 
under linux.
If you have any further suggestions for the linux code I would be glad to look 
into it.
