[Dev-C++] Question about the Dev-C++ license

[Christoph P. <Chr...@we...>]

In the last months I created a 3D engine based on Direct3D. I compiled 
it in Dev-C++ as dll. I intend to publish it in the internet. Of course 
I'll show the users the license agreement of Dev-C++.
Would it be legally if I publish it in the internet? And would the users 
be allowed to sell games they made using this dll?
I'd be thankful for a fast and obliging answer.
With kind regards
Christoph Peters.

I'm only a user of Dev-cpp, so please don't consider what I'm going to
say as *the verb*, but in my opinion, you must consider this:

dev-cpp comes with a GPL licensing scheme; this means that you can
freely use it and redistribute it - together with sorces and a copy of
the GPL license. Moreover, you can modify it or take pieces of code from
it and insert them in a new work or link towards dynamic libraries but,
according to GPL, the derived work *must* be GPL'd.

When you use dev-cpp to edit, debug and compile your code you are only
using a GPL application and, as long as your software does not contain
pieces of code nor is dinamically linked towards dev-cpp libraries, you
can release your work with the license you prefer (even a commercial one).

A final consideration: I'm not a lawyer, and this matter is not so
straitforward as someone can guess; I suggest you to take a look at GNU
homepage for more documentation (included the 13 or so page GPL license)
for more info.

cheers

[Dev-C++] Question about C++

[Vivek J. <viv...@ya...>]

This is just a sample code that compiles using the
Microsoft C++ compiler but seems to be giving problems
when compiled in Dev-C++. The problem is that I am
trying to port a library to Dev-C++ but this kind of
functionality has been used in the library and I am
getting all sorts or wierd errors because of this.

What am I missing out?

Regards,
Vivek Jishtu

#include <iostream>

class First{

public:
     void SomeWork()
     {
        std::cout <<"Inside SomeWork";
     }
};

class Second
{

public:
    void myfun(First &obj)
    {
      obj.SomeWork();
    }
};

int main()
{
 Second Obj2;
 Obj2.myfun(First());
 return 0;
}

Without seeing the error-messages I think the problem is the temporarily
instantiated object of class First in Obj2.myfun(First()).

myfun() takes a reference to a First object, which in the above sample
is a temporary instance.

This line receives a non-const reference. You can't get a non-const 
reference from a temporary object.

Ta-da!!! Here you are using a reference to a temporary object.

Thanks for your reply. But the problem is there is a
lot of code in the library I am using. It compiles
using Microsoft based compilers. Let alone an error
there is not even a single warning that is displayed
while compiling using Microsoft based compilers.

I also tried compiling this code using an older
version of GCC under Linux but there I got some other
error.

Non const references can only bind to lvalues. A temporary is an rvalue.

Using code in this way requires a compiler that works the way you
expect. Or in other words: that code is not portable. As pointed out in
the postings this concerns non constant references to temporary objects.

Switch off MS specific language extensions on your MS-compiler (/Za).
What do you get now?

gcc error messages may vary from version to version ;-)

Good Morning:

     DEV is an IDE not a compiler.=20

     I suggest you use the Microsoft compiler, and quit bugging =
everyone.

     If this is in a foreign language, Learn it.

Read here:
http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/license.html

And if you don't use C++, just C, then you are also allowed to make close=
d source=20
applications.
So there is no problem with GCC about licensing. But DirectX is going to =
give you=20
troubles. Search the archives of this mailing list around 7th of Septembe=
r this year and a=20
little before for more mails about this.

To be precise, there is no such thing: "dev-cpp libraries". Dev-C++ is ON=
LY a frontend, a=20
GUI for GCC, nothing more. Go to http://www.mingw.org for details about t=
he libraries. And=20
you may choose a commercial license, even if you link with MinGW librarie=
s.

So you may develop commercial applications with Dev-C++. Just take into a=
ccount, that=20
DirectX has a different license.
