Using Makefiles to Compile Your Application

Using Makefiles to Store Information for Compilation on Linux* OS or OS X*

To run make from the command line using the Intel® Fortran Compiler, make sure that /usr/bin and /usr/local/bin are in your PATH environment variable.

If you use the C shell, you can edit your .cshrc file and add the following:

setenv PATH /usr/bin:/usr/local/bin:$PATH

Then you can compile using the following syntax:

make -f yourmakefile

where -f is the make command option to specify a particular makefile name.

Generating Build Dependencies for Use in a Makefile

Use the gen-dep compiler option to generate build dependencies for a compilation.

Build dependencies include a list of all files included with INCLUDE statements and .mod files accessed with USE statements. The resulting output can be used to create a makefile to with the appropriate dependencies resolved.

Consider a source file that contains the following:

 module b
 include 'gendep001b.inc'
 end module b

 program gendep001
 use b
 a_global = b_global
end

When you compile the source using the gen-dep option, the following output is produced:

 b.mod : \
 gendep001.f90
gendep001.obj : \
 gendep001.f90 gendep001b.inc

This output indicates that the generated file b.mod depends on the source file gendep001.f90. Similarly, the generated file gendep001.obj depends on the files gendpe001.f90 and gendep001b.inc.
