Exactly. Actually, as time passed, the plugin system became more and 
more complicated. Their plugin system is now called SCF, the Shared 
Class Facility. It is something like a simplified version of COM. In CS, 
everything is a plugin: the canvas, where the renderer draws, the 
engine, the map loader, everything. They are all (should be) independent 
- more or less.
However, CS has some core static libraries: for math stuff, OS specific 
stuff, etc. And there is a huge design flaw in it: there are about 5-6 
static libs, and some of them have cross-references. That is: libcssys 
needs libcsutil, and vice versa. That is a HUGE design flaw.
And CS's too much modularity, and flexibility makes it a bit jelly-like: 
you can't easily get it to stand stable.

CS is not the best if you look at it from a "3D engine" perspective. It 
is more like a "3D operating system". Or just an "operating layer - and 
some 3D" :) And I think this is why it goes too slow. There are always 
redesigns, rewrites, re... Even now, core things are redesigned, 
rewritten, etc. (Bad design) This takes a lot of time, and slows down 
the project a lot. You know, it was started in 1997!!!! That's 6 years 
already. SIX! And there's NeoEngine for example, which is only 1 and a 
half (maybe 2) years old, and it is already better than CS.

If you need a look of CS, look at PlaneShift:
http://www.planeshift.it

Well, I ranted enough of CS. Now lets point some strenghts of it:
1. The new renderer
As I said, if it is ready, it will be awesome. But when???
2. Plugin design
After all, this plugin design allows decent flexibility, and it is well 
documented, but not too easy to understand.
3. Portals and sectors
Yes, CS has decent portal support, which allows you to do many tricks, 
like and endless stairway up, etc. Portals support space warping. 
Sectors and portals are hard to understand, but once you get it, you'll 
have a powerful tool in your hands.
4. Documentation
The whole engine is very well documented, and there are many-many 
tutorials, which makes the complicated start somewhat easier.
5. Software renderer
It has a software renderer, however it is nowhere near UT's software 
renderer, but it is good nevertheless - if you need it (I think you don't :)

Well, I said what I learned so far in my CS career :)

Good luck!

[David M. <ci...@ya...>]

Well you hit the nail on the head.

I have tried CrystalSpace and to say the least I was
confused out of my
skull. As for all those DLLs, from what I did understand
CrystalSpace uses a
plugin system (i.e. it only loads the sections of code it
needs). So I
probably won't need to worry about all the DLLs just those
that have what I
want.

I will check out the other libraries and get back to you
with my decision.

If anyone else has any suggestions, Please feel free to
give it.

Sincerly
David Mcken

Re: [Dev-C++] delete statement gives segmentation fault error

[David M. <ci...@ya...>]

Hmm, it works fine for me.

I tried a few changes to your main() which follow:

int main(int argc, char* argv[])
{
   argv[0] = "dc";
   argv[1] = "rate = 2.5; distance = rate * 5;";
   argc = 2;
   switch (argc) {
     case 1:
       input = &cin  ;
       break;
     case 2:
       //Modified
       input = new istringstream(argv[1]);
       if(input == NULL) {
         cout << "Error with new" << endl;
         return 1;
       }
       if(!input->good()) {
         cout << "Stringstream not created properly" <<
endl;
       }
       break;
     default:
       error("too many arguements");
       return 1;
   }
   table ["pi"] = 3.1415926535897932385;
   table ["e"] = 2.718281828459042354;

   while (*input) {
     get_token();
     if (curr_tok == END) break;
     if (curr_tok == PRINT) continue;
     cout << expr(false) << '\n';
   }

   if (input != cin) {
     //Modified
     cout << "About to delete input" << endl;
     delete input;
   }
   //Modified
   system("PAUSE");
   return no_of_errors;
}

My only other change is instead of including
#include <strstream>
I included
#include <sstream>

Your code should work fine though. All I did was do some
error checking to
see if something is going wrong before we reach the delete.

[Dev-C++] delete statement gives segmentation fault error

[Dawood V. <da...@ku...>]

Hello every body,
	below is a straight code from Stroustrup's classic.  I am running 
bloodshed DEV-C++. At the end, it is trying to delete the object "input" 
using delete statement.  It straightaway gives me invalid memory or 
segmentation fault error.  Also, if I comment the delete statement, the 
code works fine as it should be.  Actually it happens, only when I try to 
pass the command line arguement. As u all know, it is the famous calculator 
example from the 6th chapter of the book.  Right now, I am in the 6th 
chapter, so I do not have a very good idea about new and delete 
statements.  According to me the code should work, as we are trying to 
delete the object we explicitly created.

#include <iostream>
#include <string>
#include <map>
#include <cctype>
#include <strstream>

enum Token_value{
       NAME, NUMBER,END,

[Dev-C++] Problem with macro params containing commas

[Jean-Eric C. <je...@rp...>]

Hi,
I'd like to pass params that contains commas to a macro.
But the macro processor think that the passed param is 2 parts (separated by the
inner macro). It's normal, but not what I want...
Is there a way to do it differently?
Thanks
-jec

#define MACRO_PARAM_1 <class First,class Second>
#define MACRO_PARAM_2 Fn_Pair<First,Second>

FN_DEFINE_TEMPLATE_CLASS_METHODS( MACRO_PARAM_1, MACRO_PARAM_2, Fn_Kind,
Fn_Pair_CLASS_ID );

That doesn't work.
gcc says that FN_DEFINE_TEMPLATE_CLASS_METHODS requires 4 parameters and that 6 are passed!

Re: [Dev-C++] (no subject)

[<or...@vp...>]

Hi!

A few more things I left out:
PlaneShift in fact runs on Mac, but it is slow. That's why I said, 
you'll likely have problems. However, when then new renderer is ready, 
it WILL rock! The new renderer is really cool, but I'm afraid, that it 
will get ready too late. Also, even if it is ready, the whole CS will 
need to be ported to it, so that will take again some time. I was very 
fond of CS, I watched it's progress for 3 years by now, and I liked it 
very much. Until last month, when I accidentally found NeoEngine :)

And one more thing about NeoEngine: it has a modern engine design, with 
vertex buffer locking, and such. It is also not big (compared to CS or 
OGRE) and compiles quickly.

Well, that's all.

Well, CS has problems with Mac OS, as far as I know, as PlaneShift (the 
largest CrystalSpace project) doesn't run on it. So you'll likely have 
problems there. Also, Crystal Space doesn't have any Dev-C++ project 
files, but it can be compiled with MinGW. However, the compilation 
process is not the simplest I've seen. And CS tends to have lots of 
bugs, and goes on very slowly. They say, that the "new renderer" will be 
ready in June. Well, it has already passed, and they are nowhere near 
ready with it. The current OpenGL renderer is slow, and doesn't support 
shaders at all.
The engine's design is good, but there are LOTS of unimplemented things. 
It wants to be extensible, and flexible, but it actually isn't. It's 
plugin system makes it VERY bloated, as everything is a plugin. Even if 
you make a new mesh type, it will be a different plugin. There are 
currently 122 (!) DLLs in my root CS dir, and that is too much I think. 
Also, they are not regular DLLs.
CS doesn't have a native editor, however there are many exporters. Has a 
map2cs converter, that converts .map files to CS maps.
CS has network support.

Another choice might be OGRE - http://ogre.sf.net
Howevever, you can only develop with OGRE in MSVC for Windows, don't 
know about Mac. Dev-C++ is not supported (doesn't compile with MinGW).

You might take a look at NeoEngine - http://neoengine.sf.net
I currently prefer that, as it is simple, very easy to use, rapidly 
evolving, it is also extensible, has Dev-C++ support (has project files) 
and runs on Mac. It has a very efficient chunked file format. Physics 
support is currently added. NeoEngine also supports vertex and fragment 
programs. I like NeoEngine, because it is easy to use. I recommend this 
one. There is only one problem with it: documentation. There are almost

In Dev-C++ (actually, in GCC, the compiler in Dev-C++), you have to add 
libraries in the form:
-l<libname>, if a library is named like this:
lib<libname>.a

So add -lcomctl32 to your linker settings.

However, it seems more likely that you have a corrupted library. 
Download the win32 runtime from http://www.mingw.org. You need the 
headers and the import libraries.

Does anyone have a suggestion for a good 3d library,
requirements are listed
below:
1. Must be portable to at least Windows and X server (that
includes Mac OS
X).
2. OpenGL support (well DirectX won't work on anything that
is not windows).
3. TCP/UDP socket support.

CrystalSpace seems to be my best choice. Any other
suggestions?

You don't need std:: for malloc. Also you should use
sizeof(A) instead.

ptr1 =   (A*) malloc( sizeof (A) );

You are missing () around the thing to be casted.

ptr1 = static_cast<A*> (    malloc(sizeof(A))    );


Your other example here has them:

ptr1 =   static_cast<A*> (std::malloc( sizeof (*ptr1) ) );

[Dev-C++] problem with static casting (C++)

[Zheo <zh...@ho...>]

I´have wrote an example to show the differences between malloc and new 
(in fact, just to show that new calls constructors and malloc does not):

#include <iostream>
#include <string>
#include <cstdlib>

//Class definition

class A{

public:
    A();
    ~A();
    void setData(std::string s);
    std::string getData() const;

private:
    std::string data;
};

//Implementación de la clase
A::A():data("sin inicializar"){

   std::cout << "Constructor de A!" << std::endl;
}

A::~A(){
    std::cout << "Destructor de A!" << std::endl;
}

void A::setData(std::string s){
    data = s;
}
std::string A::getData() const {

    return  data;
}

  //Main program

int main(){

using std::cout;
using std::endl;
using std::cin;

A *ptr1, *prt2;

    cout << "Creamos los objetos uno con free (prt1) y otro con delete 
    (ptr2)" << endl;

    ptr1 =   (A*) std::malloc( sizeof (*ptr1) );

    prt2 = new A;

    cout << "Que contiene prt1?" << endl;

    //Ups!!
    ptr1->setData("we");
    cout << ptr1->getData() << endl;

    cout << endl;

    cout << "Y ptr2?" <<endl;
    cout << prt2->getData() <<endl;

    cout << "Ahora destruimos los objetos con free y delete" <<endl;

    free(ptr1);

    delete prt2;

    cin.get();

}

In the line: (where ptr1 is a pointer to datatype A)

    ptr1 =   (A*) std::malloc( sizeof (*ptr1) );

I MUST use a C-style casting, and if I try

    ptr1 =   static_cast<A*> std::malloc( sizeof (*ptr1) );


The compiler gives me the following error:

example1.cpp: In function `int main()':
example1.cpp:49: parse error before `::' token

What I´m doing wrong ? According this example from The C++ Programming 
Language it should work with a static casting, isn´t it?:

void f()
{
int* p = static_cast<int*>(malloc(100)) ; // new allocation used as ints
// ...
}


Thanks in advance

Please,
How can I use common conrtols in Win GUI Application in Dev C++ ? When I add
'#include <commctrl.h>' to the begin of source file and try to call
'InitCommonControls()', error code

' [Linker error] undefined reference to InitCommonControls@0 '

appears. I tried to add the 'libcomctl32.a' to the project (Prject/Project
Options/Parameters/Add Library or Object), but then linker said

' ../../lib/libcomctl32.a C:\DEV-CPP\mingw32\bin\ld.exe file format not

'1 C:\DEV-CPP\mingw32\bin\lib\libcomctl32.a parse error'.

I'm using DEV-CC 4.9.8.0 
My questions are:
How can i find out, what "__gxx_personality_v0"  is the alias for? There is
no substring defining a variable or function or something else in that
string. The original message is:
 					[Linker error] undefined reference
to `__gxx_personality_v0'

Are there sections "compiler-"& "link-messages" within the documentation?

Hi, Roberto

IMHO there is no way to turn off that option, it seems that 4.9.8.1 
inserts it everytime it formats the command which will call the (Gcc) compiler.

Probably one may modify the source code of the program and recompile it.

But you do not use any facilities of in your code.

Better: #include

The above line is wrong. There is no string constructor taking a char as an
argument.


So your code becomes:


#include 
#include 


int main()
{
using namespace std;

char ch = 'z';
string p;

p.push_back(ch);
system("PAUSE");

return 0;
}

Dear Users,

   I am using the new 4.9.8.0 and I am trying to run
the hello world program in C.
   An error message is appearing telling me "unable
to run the program".
   Looking at Tools-->Compiler Options I saw some relevant
points that I suspect will solve the problem, but I will not
change them.
   Somebody knwos what is happening? Somebody can point what
chages must I have to make?

[Dev-C++] virus help.

[<ten...@ne...>]

Thank you all.
I did as it were reported.
First I went to 
http://www.pandasoftware.es/virus_info/enciclopedia/verficha.aspx?lst=sol&idvirus=40369, 
as pointed by Javier Mateos, I downloaded pqremove and it did its work.
However, just the work which appears in the details are just what I did 
 (delete Registry key, delete file and kill process) but then it 
reappeared, then that was a re-infection. So that was enough for kicking 
it out from my computer.
Then I downloaded the update pointed by a couple of you and downloaded 
the MS security update and installed it (well, I've not yet done it, but 
I'll do; I got the spanish and I should get the english) and as 
suggested I installed a firewall I had and blocked all those ports. It 
reported an access trial from 135, I set it so it will send them to a 
log and don't tell more, I'll see in a minute how many trials there were.
And I hope now when I disconnect it won't have any problem.
I see at task manager... and there is no msblast.exe. And I didn't had 
any error in svchost.

Thank you all again.

Hossein,

Thanks for your reply. My apologies for providing such a cryptic description
of my problem and also for the misleading subject; I didn't mean to imply
that I thought the compiler was at fault.

I'm using Dev-C++ 4.9.8.0. A search on Google turned up a
number of references to this error but no solutions as far as I could tell.
I tried your suggestions of placing "()" or a blank after the code fragment
seqref<T> but that didn't change anything. My knowledge of C++ is minimal
and I don't know how to follow up on your suggestion regarding the
"name as the parent of its iterators of type RandomAccess".  I checked the
on-line version of the GNU compiler manual but didn't find anything helpful.
Below I have included the output of the compiler log and a somewhat longer
fragment of the code. I hope this will provide a few more clues to you or
some other kind C++ guru.
Thanks,
Gary Richardson
