I am trying to run nvcc compiler driver through libtool, and I keep getting errors about compiler flags which are not supported by nvcc:

address@hidden:~/sandbox/libdesc/libdesc/trunk$ /opt/local/bin/glibtool --mode=compile --tag=CC nvcc -c -m64 -arch=sm_11 -g -DTIMER -Xcompiler -fno-common -I/usr/local/cuda/include/ -o cliques_cuda_int.lo glibtool: compile: nvcc -c -m64 -arch=sm_11 -g -fno-common -DTIMER -I/usr/local/cuda/include/ -fno-common -DPIC -o .libs/cliques_cuda_int.o
nvcc fatal   : Unknown option 'fno-common'

This is understandable because -fno-common should be prepended with -Xcompiler in nvcc call. One would expect that libtool should do it automagically, since it has some kind of CUDA support built in.

What am I doing wrong? Is there any method to override regular libtool behavior to put -Xcompiler before flags it adds?

I'm using libtool 2.4 from MacPorts on Mac OS 10.6.5.

Any suggestions will be appreciated.
