[Dev-C++] "Best practices" for cross-platform development

[Thomas S. <ml...@hp...>]

Hi all,

I'm new to C programming. I spent a great deal of time looking into IDEs
that would help me learn C and help speed up the development process. I was
also looking for an IDE that would provide some cross-platform
capabilities--Dev-C++ seems to fit this profile.

Being new to C I'm not sure what the best way would be to use Dev-C++ to
ensure my programs remain compatible with multiple platforms (in particular,
Windows and *nix).

The program I plan to write will primarily be console-based with (possibly)
a GUI as a frontend.

Does Dev-C++ fit this use well? And where might I find more information
about using Dev-C++ for this purpose as well as general guidelines for
programming with multiple platforms in mind?

Thanks in advance for your help.

Tom

[Dev-C++] Changing Editor font...

[Leeman S. <me...@mo...>]

I'd like to change the editor font to one that does not show in the list 
of available fonts.

Is there a way for me to do this?

Perhaps I use a diferent version and the name of the files changes, I 
use dev-cpp 4.9.9.2 and have it installed in c:\dev-cpp .
So, (only to make me sure):
Do you have installed dev-cpp in c:\dev-cpp or in another directory ?
If not, could you type: dir (after step 4) and paste the result here ? 
(dir command prints the files and directories that you have in your 
actual working directory). To make you the things a bit easier, type: 
dir > dir.lst with this you will have a file called dir.lst with the 
output of dir command.

Try using g++ instead of mingw32-c++ in step 6

Re: [Dev-C++] Error messages

[Alfred P. R. <al...@ya...>]

Hi Noorez,
 
Usually that comes from using a null pointer.  Address 0 is mostly verboten.  An access violation during execution will probably cause the kernel error.  Possibly currentFileName isn't initialized?  Or possibly the pointer is dangling?

Why? Are you thinking about your file read? Search for and concatenation
of '\r' and '\n' can be done directly on std::string objects.

Probably 32-bits of length on a 32-bit system, so 4.2 billion elements.
And probably 64-bits of length on a 64-bit system, so 1.84467441e19
elements.
To check for sure, try cout << vector<char>::size_type.

You can download the STL manual at

Re: [Dev-C++] file handle error

[Per W. <pw...@ia...>]

I don't know what line you marked.

However, PLEASE try and use std::string and not immediately change over to
C arrays. C character arrays are perfectly fine to use WHEN YOU KNOW HOW
TO USE THEM.

Now you read a line of text from the edit control into a std::string
object.

Then you immediately ask for a pointer to a zero-terminated string using
the method c_str() and type cast into a writeable pointer:

Finally, you try to concatenate more chanracters to the c string...

Exactly HOW do you think string:c_str() should now about your intentions
to concatenate more characters and reserve room for these extra
characters? You should do ALL manipulation on the std::string.

You typecast c_str() to (char*) just to be able to play with the c string.
However, the c string is NOT meant to be played with. It is a read-only
string!

Hi,
  I haven't used  a screen reader, but I think it could mess with 
graphicals interfaces.
Perhaps if you could tell us with screen reader are you using we can 
install it a see which dificulties are involved when using it, and may 
be dev-cpp could be improve for blind people.
By the way, to use g++ from the command line you have to (I assume that 
you have done the default installation, this means that you have 
installed devcpp in c:\dev-cpp\bin):

1- Edit the program with notepad (or another text editor, it dosen't 
matter wich one while it save the file in plain text), for a first try, 
save it in c:\dev-cpp\bin, and named it first.cpp .
2- Open a console, this could be achived by pressin windows + R, this 
open a windows where you must write cmd, and then press enter, or go to 
Start -> Accesories -> System Simbol. I use windows XP in spanish, so I 
not sure if this is totally correct.
3- Well, now you have a console windows, some times called msdos window. 
This come from the golden days of msdos, if you are 16 perhaps you 
haven't used this operating system.
4- now type: cd c:\dev-cpp\bin and press enter
5- cd comes from change directory, so know you are in c:\dev-cpp\bin .
6- to compile type: mingw32-c++ first.cpp -o first.exe  and press enter
7- after some seconds you should have the program compiled
8- to run it type: first and press enter
9- the Hello world messages appears on the screen.

I must say that I really don't know if screen readers works with console 
windows, I hope yes.

The open file function of my program appears to be crashing at the line I

it. The function is below:

#include "SML.h"

Easy does it.
just select "build all, build, or execute.

RE: [Dev-C++] Reading from text file

The STL string class has a c_str() method that will give you such an object.
With vector<char> you would probably use &v[0].

you are vi or blind!
Don't wory,you didn't offend me or something,I'm just trying to say
there are other ways to acomplish it
And with my screen reader I can easyly see if there is a mistake in the
code
Even if it's just a ; or > or what ever
And that's how I'm reading the "teach your self c++ in 21 days",with my
screen reader!
And I can brouz eatch letter of a code ritten on the book,so that's not
the problem
To per :
Hi per,can you read my last email and give me an advise about the
skript?...
Thanks
Regards
yakir

[Dev-C++] Hi per

[yakir a. <ya...@za...>]

Hi per,
Thanks for that, how ever , now I understand it all!
The problem is not me nor the compilers nor the ide's
It's just my screen reader's problem,and the problem is:
When I open devc.exe I can swich tabs If I want by pressing control+tab
But when I create the projekt and  in the text editor, I can't switch to
the project tab nor select any thing that's on the screen exept for
going to the menus like file,help,debug,exequte. 
So if the thing is that you have to select the project tab,I can't do it
with the screen reader for now
How ever,I have a friend that programms with c++ [he sujested me
learning it and not vb in the  first place],and he uses a screen reader
two,and he has a screept he rote for bloodshed
Maby I should ask him to give it to me
But I just nead to understand if that indeed is the problem,I mean,the
swiching tabs,is it important?
To let ya understand better what I do,I'll say it in steps:
I open devc.exe[5.9.9.2], select file ,new and new project
Then I select aplication in the combo box and select c++ project,and
press on ok butten
Then I open file,new ,sors file. paste the code,press control+f9 and the
dialog 
Appeers,but exits 5 seconds after it did ,and then I press f9,and a
dialog pops up saying"worning!,not compiled"
Maby it's indeed the swich tabs problem?
What do you think
Regards
Thanks
yakir

I have to go out for an hour or two. If you are still stuck when I get
back, I'll see if I can help some more - however see my previous answer
during the time.

Re: [Dev-C++] Hi jonathan

[Per W. <pw...@ia...>]

Empty lines does not matter at all - C and C++ allows white space
(space, tab, newline, ...) to be
inserted just about anywhere.

The places where you should avoid placing white spacing is:
- Within ''
- Within ""
- Between digits of a number
- Between charactesr (and digits) of a function or variable name.

Anyway, this is what I did:

I opened Dev-C++ - the machine I currently sit at have version 4.9.9.2
installed, but it should work the same with all versions that starts with
4.9.

Selected File/New/Project

Specified 'Empty Project' and pressed 'Ok'.

Created a new directory named 'hello' and moved into it.

Named the project 'hello.dev' and pressed 'Save'.

Made sure that the 'Project' tab was selected on the left side of the IDE
and then right-clicked on the top-most item in the tree.

Selected 'New file'.

Cut the source code from your mail and pasted into the new editor view.

Pressed Ctrl-S to save. Specified the name 'hello.cpp' and pressed the
'Save' button.

Pressed Ctrl-F9 to compile. A popup dialog displays 'Status: Done'

If I close the popup dialog and at the bottom of the Dev-C++ window select
the 'Compile Log' tab, I find the following 8 lines of text:
Compiler: Default compiler
Building Makefile: "C:\usr\src\test\hello\Makefile.win"
Executing  make...
make.exe -f "C:\usr\src\test\hello\Makefile.win" all
g++.exe hello.o  -o "hello.exe" -L"C:/tools/Dev-Cpp/lib"

Execution terminated
Compilation successful

If I then press F9 a new text window is started with the running program.
The following two lines are output:
Hello World!
Press any key to continue . . .


If you get into troubles when compiling the program, we can help you if
you do two things:
Select every single character in the edit window and paste into your mail
- I assume you have already done this, since the code I cut from your
previous mail did compile and did work.

Select the 'Compile Log' tab in the bottom of the Dev-C++ window. To the
left of the tab, there is two fields:
'Total Errors:' and 'Size of Output:' and to the right is a field 'Compile
Log:'

Copy these three fields (actually, the Compile Log: field to the right is
enough) and paste into your mail.

By looking at both your source code and the output text from building the
application, we should be able to figure out what goes wrong.

[Dev-C++] Hi per

[yakir a. <ya...@za...>]

Hi per,
About your questions:
I don't have any programming knoeleje, how ever I am good with other
computer stuf
The problem for me to understand ya  is just the thing you use a highly
complikated langwij
Instead of telling me how to get to the command line
Btw,what do you mean by the command line,is it the windo that apeers
when you go to devc.exe?
I mean,where you have all the menus like debug , file,help. and all
that?
Or you have to go to another place to open the command line
And after I write the code in notepad and save it to"hello.cpp".what do
I use,do I use open in the file menu?
Or type the command to make it a hello.exe  file with out using open?
Thanks
And try to sound as if you wher talking to a 10 year old kid
please*smiles*
Thanks man!

[Dev-C++] Hi jonathan

[yakir a. <ya...@za...>]

Hi
Thanks for that man
I tried doing what you sed:
I went to notepad,rote the code you gave me,and pressed control+c to
coppy it,and then I pasted it to dev
I  created a new projektand deleted what dev rote there,I pasted in the
code,pressed control+f9 to compile,and this is what went out
#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
cout << "Hello World!\n";
system("PAUSE");
return 0;
}
But there wher stil errors,I'm starting to get despret
And I have another question:
Are the blank lines important?
I mean, if I write:
#include <iostream>

#include <cstdlib>
Or:
#include <iostream>
#include <cstdlib>
I mean,do the blank lines represent something?
Or I can write how I linke
And about my main problem that I can't compile anything, perhaps can you
figur the problem in the code I rote above?
Or tell me how to use mingw with out the dev ide

Re: [Dev-C++] Hi verne

[Per W. <pw...@ia...>]

It feels a bit strange to mostly read only reading one side of a
discussion.

It was me who suggested that you should maybe try using notepad or similar
to write your code and then compile directly from the command line. I have
never tried a screen reader software, but it feels to me that it could
easily get confused by a highly graphical development environment with
lots of small sub-windows all over.

Anyway: if you do write your code in notepad, you don't have to "paste"
the code into the compiler. The compiler don't care the slightest what
editor you used to write the code, or what visual feedback was available
when the code was written. All it wants is for the source to be stored in
one or more files.

As I wrote before, a single source file "hello.cpp" can be built into a
working command-line application with:

g++ hello.cpp -o hello.exe

g++ is the name of the compiler, and must be in your search path.

hello.cpp is the name of your source file, and you should move to the
directory where you store the source file before running the command.

The name after -o is the name you want for the runnable program. If you
don't specify -o and a name, the resulting file will be called a.exe -
this works just fine, but after a while it gets a bit hard to remember
what a.exe actually does.

I must confess two things:

I don't know very much about how blind people really uses their machines,
so it isn't so easy to put myself into your situation.

My next problem is that I don't know exactly how much computer knowledge
you have. You could have been using computers your whole life (possibly
also programmed in other languages), or you could be quite unexperienced
with computers.

These two things makes it quite easy for me (and probably most other
people on this list too) to think or write "just do it" instead of
considering any problems involved. We live in a world of visual feedback
and tend to quantify difficulties based on our own experiences.

[Dev-C++] Re: Hi,my first problem

[Jonathan D. <gri...@ho...>]

Hi Yakir,

Per was saying that you can use any text editor such as Notepad to write the 
code for your program.  This might be easier for you since Dev-C++ has a lot 
going on in it's interface.  I wanted to try to help you with what you 
posted, though.

Just as Per said, you have some code left in your source file that Dev-C++ 
put in there automatically for some reason.  If you're following the book 
that you have, you wont want to start like this.  Instead, when you make a 
new project, delete everything in it that Dev-C++ automatically puts in.  
Then start writing your code.  Here's my version of what you should be 
trying to do with your source:

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    cout << "Hello World!\n";
    system("PAUSE");
    return 0;
}

//end of program

If you make a project with a source file (.cpp) that has only this written 
in it, then compile and run it, this will create a .exe file that displays:

Hello World!
Press any key to continue...

Keep emailing if you have any more questions, Yakir.  If you can get this to 
work with Dev-C++, then we can know better how to help you.
