Failed to connect to libgfortran.a

Question

I have gfortran installed on my system and the file libgfortran.acan be found in /usr/lib/gcc/x86_64-linux-gnu/4.6/. Using nm, I made sure that the function is _gfortran_compare_stringdefined there:

$ nm /usr/lib/gcc/x86_64-linux-gnu/4.6/libgfortran.a | grep _gfortran_compare_string

Returns

0000000000000000 T _gfortran_compare_string
0000000000000000 T _gfortran_compare_string_char4

But, the linker of my CUDA-C program throws errors:

/usr/local/cuda-6.0/bin/nvcc --cudart static -L/usr/lib/gcc/x86_64-linux-gnu/4.6 -L/home/chung/lapack-3.5.0 -link -o  "pQP"  ./src/pQP.o   -lgfortran -llapacke -llapack -lcublas -lblas -lcurand
nvcc warning : The 'compute_10' and 'sm_10' architectures are deprecated, and may be removed in a future release.
/home/chung/lapack-3.5.0/liblapack.a(ilaenv.o): In function `ilaenv_':
ilaenv.f:(.text+0x81): undefined reference to `_gfortran_compare_string'

and then another error again related to libgfortran:

/home/chung/lapack-3.5.0/liblapack.a(xerbla.o): In function `xerbla_':
xerbla.f:(.text+0x49): undefined reference to `_gfortran_st_write'
xerbla.f:(.text+0x54): undefined reference to `_gfortran_string_len_trim'
xerbla.f:(.text+0x66): undefined reference to `_gfortran_transfer_character_write'
xerbla.f:(.text+0x76): undefined reference to `_gfortran_transfer_integer_write'
xerbla.f:(.text+0x7e): undefined reference to `_gfortran_st_write_done'
xerbla.f:(.text+0x87): undefined reference to `_gfortran_stop_string'

But, using nm again, I found that _gfortran_st_write, etc. defined in libgfortran.a.

Note. Lapack uses libgfortran. I recently installed lapack and ran all the tests, and they all passed.
