[CP2K:8310] Problems installing libgrid

[Iain Bethune]

Hi Daniele,

These issues are now fixed in the latest SVN.  For machines where you are cross-compiling you need to be able to specify flags for a native build for the helper progam generate.x.  This is now done by FCFLAGS_NATIVE in config.in, and for gfortran the correct option is ‘-march=native’, for the Cray ‘ftn’ compiler script ‘-target=native’ is correct.

Re: echo -e, this is something that depends on the shell you are using.  I replaced all of them with use of the builtin printf, which should work portably irrespective of whether ‘echo’ understands -e or not.

Please give it a go and let me know if any further modifications are needed.

Cheers

- Iain

This should be achieved by applying the patch  attached.
