Problem compliling library with nvcc

Hello,

I just added cufft into a src of my library (instead of fftw). When I compile, it works fine. I use CFLAGS = -Xcompiler -fopenmp -lgomp -O3 -m64.
All my src are .c except one, let’s say function19.cu where i added cufft.

I had to add : COMPILE.c= (CC) -c (CFLAGS)
.cu.o: (COMPILE.c) -o @ $<

in the makefile so the .cu is compiled to a .o file.

When i try to compile all my program it returns : /my_lib.a(function20.o): In function function20': function20.c:(.text+0x198): undefined reference to function19’

Compiling the library with -lib or -E doesn’t work : nvcc fatal : More than one compilation phase specified.

So the only solution i see is to rename all the src of the library in .cu files so nvcc will compile them all the same way.

Does anyone has an other solution ??

Thanks

Nostra.
