Compile

We need to create the file which contains all the tree dependencies for the binaries. Its not a Makefile, but a Ninja file (so dont type make is hopeless, type ninja instead).

The script to create the dependency file (aka build.ninja) is qp_create_ninja.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. Its quicker
  • Else if you are a developer and you want to be able to compile specific modules use: --development

Compilation Flags

You need to specify all the flags useful for the compilation: like the optimization flags, the Lapack libary, etc. $QP_ROOT/config contains ifort.cfg and gfortran.cfg containing the compiler flags that will be used. You can edit these files to modify the compiling options.

Example to create the Ninja file

qp_create_ninja.py --production $QP_ROOT/config/ifort.cfg

WARNING

For now you need to execute this command if you add a irp.f or EZFIO.cfg file or modify the NEED_CHILDREN_MODULE!

Compiling

Just type ninja if you are in $QP_ROOT (or ninja -f $QP_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 module directory and run ninja to build only this module.

Finally, go in $QP_ROOT/ocaml and type make
