2 newbie Makefile questions

2 newbie Makefile questions

Hi,

after some study of the manual I came up with this :

#SelectExpand
  1
  2#variables
  3
  4VPATH = C:\MinGW\lib
  5
  6objects = main.o load_screen.o
  7
  8linker_options = -lallegro-5.0 
  9
 10
 11
 12f_rep_editor : $(objects)
 13  gcc -o f_rep_editor $(objects) $(linker_options)
 14
 15
 16main.o : colours.h load_screen.h
 17
 18
 19load_screen.o : colours.h load_screen.h

It's the first makefile I've ever made.

Got a couple of questions:

1. According to the manual mingw32-make looks for a file called Makefile

I called my file Makefile.txt

When I call mingw32-make, it says that no makefile file but when I call

mingw32-make -f Makefile.txt

it finds it.

Wondering what I need to change Makefile.txt to, to get it to find it autometically.

The other question is about getting the object files linked to libraries.

I need to link to these files.

C:\MinGW\lib\liballegro.dll.a;
C:\MinGW\lib\liballegro_ttf.dll.a;
C:\MinGW\lib\liballegro_primitives.dll.a;
C:\MinGW\lib\liballegro_font.dll.a

Can anyone help me with that ?

Either Makefile or makefile will do (no extension).

cheers Arthur.

How do I save it with no extension ?

Windows automatically puts the .txt extension on it? Use quotes

Save As -> "makefile"

sweet

EDIT : that's something we say in UK. Could have just said Thanks.

Anyway, got the libraries linked now.

Changed makefile to :

#SelectExpand
  1#variables
  2
  3VPATH = C:\MinGW\lib\
  4
  5objects = main.o load_screen.o
  6
  7linker_options = -lallegro.dll -L C:\MinGW\lib\
  8
  9
 10f_rep_editor : $(objects)
 11  gcc -o f_rep_editor $(objects) $(linker_options) 
 12
 13
 14main.o : colours.h load_screen.h
 15
 16
 17load_screen.o : colours.h load_screen.h

Don't use Notepad.

IIRC, Notepad can also save without an extention if you select "All files" first.

Nope, even then it still adds a .txt

Obviously Windows knows best.

IIRC, you can just add a dot at the end of the file name to disable the automatic extensions.

And don't you just love it when you want to edit it again, you can't just double-click it without an extension without getting the "Open with" dialog. Maybe it's just best to leave it as makefile.txt.

IIRC If you also tell windows to display extensions for all file types notepad should allow you to enter the full filename after selecting "All Files".

Just type in "Makefile." (with the quotes) like torhu said. Easy as that.

You all love to hate on Windows, but in all reality, how often do most people need to save a file without an extension? It doesn't make sense not to add the default extension automatically - very few people actually want to know and type the correct extension whenever they save.

I suppose you could always get the make source and change it to accept makefile.txt as the default, since you can't get the Windows sources. Maybe one of those third party shells would know what to do with no extension though.

I don't even add an extension to text files. ::) Why would I? That should be the default type assumed by the system. And as a general rule, file extensions shouldn't be trusted anyway. If I'm not sure what type of file I'm dealing with (very rare) then I just ask `file`. Windows can't even deal with files without extensions (it asks you every goddamn time to search through two or three dialogs to find an application to open it with).

I see that even though Russia had the source code to Windows 7 to examine for months, they've decided to go with Linux after all.

How would the bulk of the code for Windows 7 compare with a big triple A game ?

The big problem for me is it adding a .txt extension even when I already GAVE the file an extension. Stupid windows.

It's also a huge security hole, i.e. "college_girls_gone_wild.jpg.exe" just shows up as "college_girls_gone_wild.jpg". Of course in Linux even a jpg extension could execute if it had the right permissions, but the user privileges had some thought put into them.

Also, from the command line (where I imagine most Linux users spend most of their time; I know I certainly do) you have to explicitly say what you want to happen (which is generally effortless). Even from the GUI, if a file is executable, Gnome always asks me: do I want to "display" this file (i.e., open it) or do I want to execute it? Of course, I almost never let any desktop environment implicitly carry out actions anyway. I generally open the context menu and select what I want to happen.

Since it came down to text editors, I would like to add my 2 cents with notepad++, a text editor used for various programming languages.. Very easy to use, and does what is required to be done.

Use quotes around the filename. That's always been step one to getting the extension you want. Or, use a better editor than notepad.
