gfortran {{path/to/source1.f90 path/to/source2.f90 ...}} -o {{path/to/output_executable}}

Show common warnings, debug symbols in output, and optimize without affecting debugging

gfortran {{path/to/source.f90}} -Wall -g -Og -o {{path/to/output_executable}}

Include libraries from a different path

gfortran {{path/to/source.f90}} -o {{path/to/output_executable}} -I{{path/to/mod_and_include}} -L{{path/to/library}} -l{{library_name}}

Compile source code into Assembler instructions

gfortran -S {{path/to/source.f90}}

Compile source code into an object file without linking

gfortran -c {{path/to/source.f90}}
