Make

I am a newbie to both fortran and linux. I’ve been trying to understand what makefiles do but not quite grasped it yet. Was wondering if someone could interpret what they do in laymen’s terms please? The reason being :
I have a program (called NUMBER) I want to run in Fortran and as part of it I’ve been given a set of instructions,
1) Go into directory NUMBER and type ./configure . this should create makefiles in the directory obj_Linux

However when I type that, I keep getting an error :
Permission denied.

2) Go into obj_Linux and make NUMBER. This creates number.exe in directory obj_Linux/bin

I am not sure how I go about “making” NUMBER?
Further to this there is a note which says :
This works for Linux x86 using ifort(9.1) and gcc(3.4.6) compilers. If the code does not link on your system, you may need to change the makefile settings relating to linking f90 and C++. The file NUMBER/number_test/Makefile.Linux is the template where the machine dependent setting should be used (you may need to change LDLIBS for your machine). Then run ./configure again from the directory NUMBER.

I use a Fortran g77. Could someone please explain to me why it’s not working for me and how I could “make” NUMBER? Many many thanks in advanced.

I tried googling 'makefile tutorials' and there are too many to list here...G4143

The permissions are wrong, change them: chmod -R a+rw ./

To make number you just enter the command "make NUMBER" (without the quotes) after the first step has completed successfully.
