I'm currently trying to install MAGMA , however trying to run "sudo make install" gives me the error:
$ sudo make install prefix=/usr/local/magma
make.check-cuda:7: *** Set $CUDADIR, preferably in your environment, e.g.,
run "export CUDADIR=/usr/local/cuda" in ~/.bashrc, or "setenv CUDADIR
/usr/local/cuda" in ~/.cshrc. Stop.
I know for sure that CUDADIR is set, and it's set in ~/.bash_profile, so I'm not sure why it's failing. Is there any reason why it might not being finding it? It seemed to work fine when I ran "make".
$ set | grep CUDADIR
CUDADIR=/usr/local/cuda
It needs to be both set and exported. By looking at the output of set
you're just seeing variables which are set in the shell... the shell will only send exported variables to programs (like make
) that it invokes. You didn't show us how the variable is set in ~/.bashrc
but I assume it's something like this:
CUDADIR=/usr/local/cuda
Change that to:
export CUDADIR=/usr/local/cuda
If you want to see what variables are exported the simplest thing to do is use env
, not set
, like this:
$ env | grep CUDADIR
