1. Compiling Problem

#4610

Posted by: 2004-06-24 23:20:46

I've been trying to compile the example at this web page: http://www.free2code.net/tutorials/programming/cpp/9/GUI_Programming_made_easy.php

but each time I try to compile it i get this error report:

Compiler: Default compiler

Executing make...
make.exe -f "C:\Dev-Cpp\Projects\Makefile.win" all

I hope you guys can help me. I've been tryng to make my first GUI for the last three days, but i keep on getting problem after problem.

Hi!
From your compiler log and the source on the site you mentioned I see that you added a file. In the tutorial there's only base.h and base.cpp. In your version there is a main.cpp. Have you tried deleteing the main.cpp from the project and only compile the base.* stuff?
If the doesn't work: Please post your code. I'm sure it's not that much and it would really help to comment on the errors.

If it was hard to write, it should be hard to read!- Do. Or do not. There is no try!

Thank you very much upCASE. Each time a start a new project in Dev-C++, main.cpp is there by default. I thought that I was supposed to keep it there. You seem to be the person that answers all the questions around ;) lol.
