Algorithm Compile

This script has been wrote to automate the compilation process. It gather gcc, g++ and fortran for each version of them.

It has been thinked as a multiplexer defining the differents branchs of the switch.

Each branch correspond to a specific way to act (with options, wit a given name, etc).

To understand it, I will explain the differents steps of the algorithm.

The first switch is ruled by the mode parameter defining the compilation directives as chain, modular, mpi, openmp and lib associations compilation.

Each af these branchs will be splitted into differents sections ruled by a main loop coursing parameters list :

• We read extension and define differents flags used to get the correct path

• For each extension we split again the algorithm using a switch for new falgs as :

  • exe_flag : It determine if the exe filename is specified or not

  • rep_flag : It determines if the repertory name is specified or not

• Once the path determined by the differents flags, we automate the compilation process calling the right method, for example :

  • gcc $parameters $lib -o $name $lib_option || gcc $lib -L $parameters -o $name || error will give a compilation via variables substitution. The || allow to test the first command, goes to the second if failed and finally call the error method to get a print. The differents used variables in this example are :

    • parameters : is the source(s) file(s) to compile

    • lib : is the specified Librairie to link

    • name : is the specified Filename of the executable

    • lib_option : is the differents added librairies option

Once the correct execute-path have been founded, the correct compilation call is applied.
