RE: [Dev-C++] linker problem

[Narvaez, V. <viv...@co...>]

Thank you all for your  responses.  I guess you can tell I'm a newbie.
Never seen a .o file.

I'm so used to compiling  as soon as I write a couple of lines to catch the
minor errors. 
I'll try it one more time...this time I'll write more code and create a main
:-)

Thanks again!!

Re:[Dev-C++] Running execs.

[<AN...@em...>]

If  the OS is Micro$oft Windows, you can use the Win32 API function WinExec:

Syntax:

UINT WinExec(
     LPCSTR lpCmdLine,  // address of command line
     UINT uCmdShow      // window style for new application
);

I believe that the problem is in the setting of the project. Delete and
rebuild the project and set the correct option. C project or C++ project,
Windows application for gui or Console application for text based program.

Re: [Dev-C++] linker problem

[Samuel K. <big...@ya...>]

The .o extension stands for object file. It is one of the steps taken in
compiling source code. The .o is normal and happens on every complier that I
have heard of. WinMain() I believe is referring to gui stuff and I am not
familier with it.

[Dev-C++] linker problem

[Narvaez, V. <viv...@co...>]

Hello all, I've been having trouble compiling my files.  I get the following
message:

C:\DEV-C_~1\Lib\\libmingw32.a(main.o)(.text+0x8e): undefined reference to
`WinMain@16'

I looked through all my files and noticed that when I tried to compile
something the compiler makes a file with a ".o" extension instead of the
".exe".  Has this ever happened to anyone or does anyone know why?  am I
doing something wrong?




 <<studentclass.cpp>>  <<string.o>> here's a ".o" file..i don't know how I
get them.

Thanks a lot!!

I'm new to Linux too, but do not use X-Window. I've not tried Linux version 
of Dev-C++ but have heard that it has some bugs and that it will no longer 
be developed. So I suggest you avoid using it. if you have X, try some 
other GUI IDE ("anjuta" for example), if you use the command line, I 
suggest "emacs".

sorry for the question,

[Dev-C++] Error Compiling

[brianp <br...@3r...>]

I posted a message to the forum but due to the lack of response I decided 
to give the list a try.

I get the following error (under the Resource tab) on Win2K compiling c or 
c++ projects (I can compile outside the project, i.e. just the sorce file).  
I have uninstalled and made sure that all the registry entries were removed 
(had to do this manually since Dev-C++ doesn't), then reinstalled.  All 
my options are set to the default.

I don't see anything in the resource file that would cause this (there
is only the default line for the icon).

The directory I am building in is dos complient.  The crazy thing is this 
all worked before.  I just can't remember if it worked after my upgrade 
from nt4 to win2k.  Can ANYONE help me?

Thanks.

The standard library comes with the compiler. Just #include the
appropriate hader files and use the facilities they provide (strange
question).

Re: [Dev-C++] Install question

[Benjamin W. <ben...@ho...>]

Jimmy,

Good morning.  I don't know the particulars regarding Dev-C++ for Linux, but 
I can tell you that on the Linux platform a *.rpm acts similarly to that of 
an install.exe file on the Windows platform.

Most software providers for Linux distribute their applications via an *.rpm 
file and basically you pull it up and execute it on your system and it runs 
through an install program.

I realize this isn't much help to you regarding Dev-C++ (unless it comes 
with an *.rpm file), but I just wanted to give you some insight on what to 
look for and expect when looking for software for Linux.

Good luck,

Ben

I tried to install the version of Dev-C++ for Linux
but I can't get it going.
Now I must say that I am new to Linux...
I got only a bunch of files extracted amongst which
were both an SETUP.EXE and a SETUP.PKG
But now Linux-guys tell me that Linux doesn't work
with exe's!  That I should get an rpm, or use a ./make
or ./configure...
Can anybody please shed some light on this...
I have RedHat Seawolf

Re: [Dev-C++] Re: Palindrome

[Jason H. <jas...@bt...>]

Hi Samuel,

Looking at your code it shows you understand what is happening to the
numbers when you try to reverse them, but I thought I'd show you a shorter
example that does the same thing. I'm not doing it to be harsh, I just hope
you can learn from it in some way:

// This loop performs a mathematical reverse in specified base
  while(inputNumber > 0)
  {
    editNumber *= base;
    editNumber += inputNumber % base;
    inputNumber /= base;
  }

In your example base would be set equal to 10, but it does work in any other
base assuming you have a way to input and output numbers in that base to the
screen. Which I do in the attached program.

In effect I am treating the two numbers as stacks, if you know anything
about those containers. I am popping a number off the end of input number
with modulus base. Then shifting the next number down into the units
possition with the divide by base. I am also pushing that number onto the
edit number (adding) and shifting it up with the multiplication by base. The
first time around editNumber is 0, so multiplying it by base doesn't do
anything, so is redundant but negligable.

Jason.

[Dev-C++] Re: Palindrome

[Samuel K. <big...@ya...>]

This will only work for base 10 and there are surely many ways of doing the
palindrome that are a lot easier to understand and more economical on
computer processor time but I thought you all might want to take a look.
(don't be to harsh on me, I haven't been programming very long)

#include <iostream>

int main(){

    int inputNumber,
        firstSentinal = 10,         //Counts up Digits

    //varible to "flip"  inputNumber


        secondSentinal = 1,
        editNumber = 0;


    cout << "Please input number:";
    cin >> inputNumber;


    while (inputNumber / firstSentinal >= 10){

          firstSentinal *= 10;
    }

    //Keeps secondSentinal from overflowing

    const int Guard = firstSentinal * 10;

    while ( secondSentinal != Guard ){

          editNumber += (inputNumber / firstSentinal) * secondSentinal;
//Does work of flipping

          inputNumber %= firstSentinal;
          firstSentinal /= 10;
          secondSentinal *= 10;
     }

     cout << endl << editNumber <<"\n\n";





      cin.ignore(256, '\n');
      cout << "Press ENTER to continue..." << endl;
      cin.get();


    return 0;
}


As I said this will only work base ten. To use it for the palindrome make
another const copy of inputNumber and then if editNumber = = inputNumber you
know that it is a palindrome. This might  be portable to hex, but I'm not
sure.

Re: [Dev-C++] ERRORS

[Samuel K. <big...@ya...>]

Are you opening a previously saved project or do you mean that you are
creating a new project? If you are opening an existing one, are you moving
your files around? What I mean is after you save them, do you stick your
project file in one directory and your source in another? That could cause
an error.

The reason I ask if you are opening a new project or an old one is you error
2. It says Could not create default code file. Default is what the system
does automiatically. It almost sounds like (if your making a new project)
that some file was misplaced. When the program makes a new project it will
also open a default source code file that contains a few lines of code. If
that source was missing it could give you that error.

Re: [Dev-C++] Problems with a for loop again

[Jason H. <jas...@bt...>]

I'm glad I could help a little, and I have a small piece of advice for =
you. That is becareful in using the do..while loop; you have to remember =
that it will always go through the loop at least once, even if there are =
no lines to be displayed, which may be an error. Atual usage of =
do..while loops is a lot rarer than that of while and for loops.

Also the index value filesize isn't valid the first time around. Vectors =
start at zero and go to size() - 1, just like arrays. Which also means =
that you will miss off the first line in the vector.

Greetings,

I change the code and used a do ... while loop and it works, If I delete =

the loop. It then reports an error project filename caused an error in =
filename.exe, restart you computer if problem continues.

Is the a problem with the compiler, should I reinstall it?

thanks for any advice.

Paul Stone.

Code below:-

// Add line numbers:
  //for(int i =3D filesize; i > 0; i=3Di-1)
  //cout << "filesize" << filesize<<endl;
  //cout << filesize << ": " << v[filesize] << endl;
