end module
This compiler command:
ifort -c a.f90
generates the following files:
• test.mod
• test.o
• payroll.mod
• payroll.o
The .mod files contain the necessary information regarding the modules that
have been defined in the program a.f90.
If the program does not contain a module, no .mod file is generated. For
example, test2.f90 does not contain any modules. This compiler command:
ifort -c test2.f90
produces just an object file, test2.o.
For another example, assume that file1.f90 contains one or more modules
and file2.f90 contains one or more program units that access these modules
with the USE statement. The sources can be compiled and linked by this
command:
ifort file1.f90 file2.f90
Working with Multi-Directory Module Files
For an example of managing modules when the .mod files could be produced in
different directories, assume that the program mod_def.f90 resides in directory
/usr/yourdir/test/t, and this program contains a module defined as
follows:
file: mod_def.f90
module definedmod
