compilation

[cmcneile]

I was trying to help my student compile qmp, I found my old compilation scripts no longer worked.
The lines below seemed to compile the code in scalar mode. (This was done for testing.)

git clone https://github.com/usqcd-software/qmp.git
cd qmp
cmake .
./configure
make

Is that a reasonable way to compile? It would be useful if the INSTALL file was updated.

@cmcneile This script works for me very robustly for parallel builds:

#!/bin/bash                                                                                                                                                                       

# build_qmp.sh
