dev-cpp-users Mailing List for Dev-C++

I work with CMUGraphics (http://www-2.cs.cmu.edu/~cm-gfxpkg/index.html)
versions 
1.5 and 2.0 in Computer Science class at school for graphics projects.
I was 
wondering if anyone had been successful in getting either version going
(preferably
1.5).  Is there some other free package that is better than this one for
basic 2D 
graphics that anyone recommends?  Thanks!

I have a project in dev-cpp which includes both source files ending in 
.cc and header files ending in .hh, when i try to compile the project, 
dev-cpp checks for dependices for the headers files also and creates a 
makefile with targets for them, the make process chokes on this.

But the thing is, if i rename the header files to .hpp dev-cpp doesnt 
check deps for them and doesnt add targets for them in the makefile 
either. The same goes for .h header files.

So is there anyway to tell dev-cpp to not do dep checking for .hh files 
and not add them as targets to the makefile.

Im using version 4.9.6.4 of Dev-cpp.

Take it easy, Mikael

Hi !
first of all: thank you very much, Tibor.
for those who might, now or in the future, be experiencing similar problems,
check this
out:

http://www.opengl.org/developers/faqs/technical/gettingstarted.htm?OpenGL+sdk#first_hit

(link in one row, of course)
the problem was: i had simply forgotten to put the lib-files
(OpenGl32.lib,glut32.lib, glu32.lib) in the Dev-Cpp \lib-folder.
now everything´s fine.

ok, have a nice sleep everybody.

This site has many GNU manuals available in chm format (very handy under
Windows!), among them libc and gcc.

Dev-C++'s manual (the ide) can be found by going tools->check for
updates, it's under help files.  The glibc manual with all the functions
etc can be found at http://www.gnu.org/manual/glibc-2.2.5.  Hope this
helps.

std::string GetName() const;


This returns a (temporary) object created using the copy constructor.


So for example if you have:


class something
{
 string s;
 public:
 something(const string *n)
 string GetName() const { return s; }
};

// ...

something so("Johnson");

string l=3Dso.GetName();


At the so.GetName() call

a temporary using the (default here) copy constructor
something::something(const something &) is called which is assigned to l
using the (default here) assignment something::operator=3D(const =
something
&). After the end of the expression the temporary is usually  destroyed
(and not at the end of the scope).

std::string &GetName();


It is returning a reference to an existing object (i assume you intend
to the data member).

Oh, sorry, I thought you got the package from dev home page, which is a devpak.

What I did was this: (having gcc[C:\Dev-Cpp\Bin] in the path)
1- I unpacked it to C:\wxMSW
2 - open command.exe
3 - cd to C:\wxMSW\src
4 - type make -f makefile.g95 and wait, then I ran over some of the other
folders seeing that in all of them the result was "make nothing to be done for
all", so I gave it as built. Well, there were a couple of utilities about
dialog editor or something like that, I cd to there and make etc.

The bad news are that I never could make it work, except for the examples that
were with it, which compiled fine, I tried some examples for Dev-C++ and I
couldn't compile any one.

The first you must do when making a project is define __GNUWIN32__ and define
UNICODE, and define __WXMSW__

And a lot of compiler options, linker parameters... search in the dev mailing
list, I don't remember when they answered me with all those options you must
provide, more or less six or seven months ago or before.

Hello, I'm trying to apply my knowlodge adquired in "Borland C++" in 
"Dev-C++", but I have found many differences.

If do you have a Manual or a link where I can find it.... I will be happy!.

Writing it would be a simple matter of cin inside the set function or pas=
s
the pointer of the string (I am assuming you want to use char*, however
writting C++ string would be the recommended way, and where you need
char*, you use the member function c_str() of string class)
The function for get the string should be something like this:
char *const function(parameters);
so you cannot modify it out of the class's functions.

Before the answer to this, you write String, C++ is case sensitive, so if
you haven't defined a class String it will say String not defined.

Now let's go with the answer: With that you say GetName won't modify the
member inside it, but you'll will be able to modify the return value,
since it is not constant and it is what you need to be constant (the othe=
r
is recommended, of course)
You have to do
const string GetName() const;
This will not modify the member while it does its work and will return th=
e
result to a constant member which won't be modified, and which will have
no access to the member, since there will be a copy of it.
With the solution you propose, returning string&, you're returning a
reference to it, so if the caller modifies it, the member will be
modified, because we can say that returning a reference is the same than
returning a pointer, with the difference that you can treat it as if it
were not a pointer, and when you access it you will access the variable a=
t
that address of memory, so you will access to the member variable
directly.

I wrote asking how to write it, because I said the package in Dev didn't
have it, that's wrong, sorry. Today I've remembered, because I found it
after searching through all the disks for gtk----.devpak, that I didn't
get the package from dev, which is for gtk2.0.0, I took it from
wingtk.sourceforge, which is a installer executable called DevEx0.1.

Just say that correction, so you know I don't know if this problem is
present in devpak from dev page.

I have downloaded the WxWINDOW package.  How does one go about compiling it
under Dev-C++??

Thanks!

Mark

Possibly

const String& GetName() const;

Are you possibly requesting help for a class-room assignment?

This is the code currently
String GetName() const;

To make the function return a const string reference, do I changeit to

String& GetName() const;

or is it now returning a String object?

My skills are shot.

I am trying to create a quick program that has a class with a private member 
that is an employee's name, and one of the member functions (public) returns 
a pointer to that private member (it's an example of what not to do).

The program's main function should go like this:

Create a class object.
Create a global pointer.
Ask for user name.
Call SetEmployeeName passing the object to it.
       Set the typed string to be the private member EmpName.
       Return to main.
Call GetEmployeeName, passing the object to it.
       Assign the private member EmpName to the global pointer.
       Return the pointer to main.
Show what the pointer is pointing at (for example cout<< *GlobalPointer << 
endl;)


any refinements would be great. Remember this is an example of what not to 
do (returning pointers to private members). I have trouble putting the 
string in to the object's data member, so I could do with some help!

I currently have an example of using namespaces

#include <iostream>

int main( int argc, char** argv )
{
    std::cout << _T("Using standard namespace") << std::endl;
    return 0;
}


could anyone give me another example NOT using cout ? Perhaps with a vector?
The standard namespace is all I have experience with.

Thanks in advance,
Daniel
