Makefiles and me - A story of sorrow

Chada

Hi,

I've been struggling with compiling files with C++ for some time now. I'm using the latest Dev-c++ compiler and SDL files to create a standard 2D game.

I'm using the following tutorials to get to grips with SDL:
http://cone3d.gamedev.net/cgi-bin/index.pl?page=tutorials/gfxsdl/index

My problem is that even when i compile a lesson for example lesson 5 i get the error message:

32 P:\Project\Makefile.win
[Build Error] [Warning] overriding commands for target `"../lesson5/lesson'

I create a new project and then add lesson5.cpp, font.cpp and font.h to the project and then compile.

Then i receive the above error message. Is there something fundamental i'm missing here ? i've inserted all the relevant files into the C:\Dev-cpp\ folders and changed the linker options to include "-lmingw32 -lSDLmain -lSDL" (without quotes).

Could anyone help me out ?

Cheers,

have a look in the actual Makefile.win file. You probably have some duplication in there.

Makefiles are horrible things.

Chada,

I had a quick look at the example you are trying to use.
There are only 2 cpp files so a Makefile may be OTT especially if you are only interested in understanding the code.

Anyhoo I got this working no probs with gcc 3.4.3 on FC3 with the following line:

g++ font.cpp lesson5.cpp -o lesson5 -lSDLmain -lSDL

Hey guys,

thanks for input so far, my major concern with DEV-C++ is a piece of code im working on for my project, i've been trying to add pieces of code to it but i receive the same error message even when i re-load the exisiting code from scratch.

I had a look at the compiler log and wondered did anyone know how to solve this:

Compiler: Default compiler
Building Makefile: "C:\Zelda Project\Makefile.win"
Executing make...
make.exe -f "C:\Zelda Project\Makefile.win" all
g++.exe src/display.o src/engine.o src/main.o src/orc.o src/player.o src/sound.o src/sprite.o src/spriteBase.o src/MenuItem.o src/Menu.o src/Font.o src/SFont.o src/Item.o src/message.o -o "game.exe" -L"C:/Dev-Cpp/lib" -lmingw32 -lSDLmain -lSDL -lSDL_mixer -lSDL_image -lSDL_ttf -mwindows -s

The system cannot find the path specified.

make.exe: *** [game.exe] Error 1

As far as i know the sdl.dll, sdl_mixer.dll, sdl_image.dll and sdl_tff all exist in the same directory as the project and i have put them into C:\dev-cpp\lib just to be sure, but still the same message.

Can anyone help ?

cheers,

Dan

*shameless bump*

Any ideas on my last post guys really stuck here

Talon.ie

ok, it's complaining about a path it can't find. Looking through the commands it's executing I can see a couple of paths.

1. src
2. c:/Dev-Cpp/lib
3. This one's implied, the directory where mingw32.dll is

First and obvious question, do those paths exist?
Does the working directory of g++.exe contain the src directory, i,e is g++ being run from the parent of src?
I'd put money on this being the problem. (not a lot though, 10cent or something :-) )

Double and triple check the spelling of your source filenames.
I'm not sure about this but you might need -L<path to dir containing mingw32.dll>

Just in case the error message is misleading, Is g++.exe in the PATH? i.e. if you just run g++ does it run properly?

And I'm probably reaching here, but is there a chance that the hyphen in the directory name is causing the problem? I know it's quoted, but try renaming it to c:/DevCpp

Good luck.
