A makefile is a script run by make (or nmake under windows) that contains information about the dependencies of a series of targets and, additionally, makes them. For example, make can build the binaries for a large software project.
Contents
Syntax
Here's the syntax to use the make command:
make Target make -C Subdir Target make -f filename Target
(ex: make -f mymakefile all).
In most projects in linux, the most common targets are:
- all: builds the full project.
- install: copies the executable files in their final destination on the system.
- clean: deletes the object and the executable files created by target all.
NOTE: Here's how to ignore built-in pattern rules!!
> make -r target
This is very important for the following rules:
%.o : %.c %.dvi : %.aux
A large project cross-platform, cross-compiler makefile methodology
Here is described a CCCP makefile methodology particularly suitable for MOHID.
Sample makefiles
In particular, the gnumake program is very documented here.

The source code of a sample Makefile is given bellow:

Troubleshoots
use DFWIN
This is a windows platform specific library. It cannot be ported to Linux. To build the code in linux you need to change it first. This is currently(20061201) the case in ModuleGlueHDF5. If you get an error attempting to make it in windows, first make sure you're calling make inside an Intel Fortran Development Console, which is where all the environment variables are correct.
ifconsol
If you get an error about an "ifconsol", then it's probably because you have incorrect environment variables. Under windows, make sure you're inside an Intel Fortran Development Console.
