Weird problem: Help on environment setup

[cding]

Hi,

I try to use CULA basic, but I can get enviroment setup down. Every time I compile my program :
$ gfortran cudaonly.f90 -o3 -i$cula_root/include -l$cula_root/lib64 -lcula -lcula_fortran -lcublas -lcudart -o nrfcuda

/usr/bin/ld: cannot find -l/lib64
collect2: ld returned 1 exit status

It reports that cannot find -l/lib64.

I have done everything about envrionment configuration in the CULAProgrammersGuide_1.1.pdf.

Below is my .bash_profile and ld.so.conf
$cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

The environment is case sensitive, so you should do $CULA_ROOT rather than $cula_root.
