Problems installing libgrid

[Daniele Fontanari]

Hello everyone,

I'm trying to install cp2k (downloaded from git) and optimizing through the 
installation of libgrid tools/autoune.
I've encountered two problems in the build process (through the script 
generate_makefile.sh which create the Makefile).
The first one is that inside the Makefile (in the section generate.x) it 
uses the flag "-target=native" which is not recognized by my gfortran, I 
guessed that maybe it was meant to be "-march=native"?
The second one is that the test are done (to my understanding) by feeding 
to generate.x some files generate_${l}_${iopt}.in (through generate.x < 
generate_${l}_${iopt}.in) and the generate_${l}_${iopt}.in itself are 
created by echoing inside some strings. Problem is (for me) that the command
echo -e "something" is used and this make the string "-e something" appears 
inside the file instead of "something"

I understand that being generate_makefile.sh 7 month old this is probably 
related to some misconfiguration of my system, and I'd like to know your 
opinion about this, but I solved my problem by replacing "echo -e" and 
"echo  -e" inside Makefile with "echo" and "target=native" with "march=native" 
and everything seems to work fine. This should be achieved by applying the 
patch  attached.
This is not really well tested, it modifies the generate_makefile.sh, you 
can still achieve the same using the original generate_makefile.sh and then 
invoking the command

"sed -i -e 's/echo -e/echo/g' -e 's/echo  -e/echo/g' -e 
's/target=native/march=native/g' Makefile"

Thanks
Daniele
