Compile

We need to create the file who contain all the tree dependencies for the binaries. It’s not a MakeFile, but a Ninja file. (So don’t type make is hopeless, type ninja instead)

The script to create the dependencies file (aka build.ninja) is create_ninja_build.py.

What utilization of the code will you do?

• If you only want the binaries (for production workflow) use the flag --production in when calling this script. It’s quicker

• Else if you are a developer and you want to be able to only compile one specific module use: --development

Compilation Flag

You need to specify all the flag useful for the compilation: like the optimization one, the mkl one .$QPACKAGE_ROOT/config contains ifort.cfg and gfortran.cfg files which have the compiler flags that will be used to compile the code. You can edit these files to modify the compiling option. Put the file path when calling create_ninja_build.py

Example to create the Ninja file

create_ninja_build.py --production $QPACKAGE_ROOT/config/ifort.cfg

WARNING

For now reload this command if you add a IRP.f90 or EZFIO.cfg file or modify the NEED_CHILDREN_MODULE!

Compile

Just type ninja if you are in $QPACKAGE_ROOT (or ninja -f $QPACKAGE_ROOT/build.ninja elsewhere). The compilation will take approximately 3 min.

If you have set the --developement flag in a specific module you can go in the corresponding IRPF90_temp and run ninja to only make the module and submodule binaries. (You can use the -f option too)

Now go in $QPACKAGE_ROOT/ocaml and type make
