Frequently asked questions at the installation

I am using supercomputer at ***. What should I do to compile the files?

ERMOD requires an implementation of BLAS and LAPACK library.
At the time of writing this page (2012), most of cluster computers have either Intel or AMD CPU, and have Intel MKL libraries installed.
Thus, first you can try with --with-mkl option.
If it works, then you don't have to worry about.

For other cases you need to specify correct BLAS / LAPACK library to --with-blas= option. Contact the technical staff in the supercomputer center to know correct specification of the BLAS / LAPACK library.

"make install" fails with some errors about permission

This is because you are not root.
By default, ERMOD tries to install the program under /usr/local/bin and plugins under /usr/local/share/ermod.
Since you are an ordinary user, you cannot access these directories.
You can change behavior by specifying --prefix option in configure.
For example, by doing

./configure --prefix=/foo/bar

the program is installed under /foo/bar/bin.
Similarly, you can for example specify --prefix=$HOME to install program under your home directory, which should be accessible from you.

I am using gfortran 4.4.x and it cannot find mkl_dfti.f90.

This is a bug in gfortran 4.4.0 to 4.4.3. Please update.
