Hola Lars-Bo Jacobsen,

=09First of all, hi everybody, I=B4m new to this list, and I hope I=
 can give you any help. I also want to apologize for my poor=
 english, as I=B4m Spanish. Any correcti=F3n about my spelling /=
 grammar / correct using of english in general, will be=
 aprreciated. (In such case, please reply to my email, for not=
 disturbing anyone from this list. Thanks :)
=09
And now let=B4s back to work:
=09=09
=09I don=B4t think that copying the files from the .TAR file will=
 cause you a problem. When I use Dev-C++ 4, I downloaded a new=
 version for GDB which had a GUI (I don=B4t like very much,=
 command-line debuggin :-) That versi=F3n was for windows (I=
 suppose you are using linux or a unix-based system, as you=
 mention tar files) 
=09That is the version I keep using even with Dev 5, and I=
 decompress that zip file in my dev-cpp directory. It overwrites=
 gdb.exe and some other libreries, and it work frawless (by now=
 :)
=09
=09However, if you aren=B4t sure, there always be the posibility of=
 back up the Dev-Cpp directory, and then, installing gdb :)
=09
=09Hope this helped you.

[Dev-C++] Task Control Windows

[Cirlei G. R. <ci...@tt...>]

I need do a kill in task in the windows. 
somebody help me.

[Dev-C++] Newbie on gdb again

[Lars-Bo J. <la...@fo...>]

Hi all

So, no one answered my question on gdp yesterday, so this newbie has to try
by him self. Since I am somehow new to programming I really need a debugger
I am rather tired of using a lot of resources on constructing code with cout
for debugging purposes. So I went to the MIINGW homepage a found out that an
experimental version of gdp exist, downloaded it, found the file gdb.exe and
copied it into dev-cpp/bin and suddenly debugging seems to work. So fare so
good, but I am in doubt.

Is this a method that can be recommended?

The gdb tar ball contains a some more directories some of which is not in
the Dec-cpp distribution (eg. /include/readline ). Should I just copy all
file from the tarball tom my Dev-cpp distribution and thus create some new
(at least one) directories? Or is the Mingw supplied with Dev-cpp different
thus making all this dangerous to the stability of Dev-cpp?

Hope someone has an idea of what I am doing and some thought on this would
be nice, otherwise I wish everyone a pleasant weekend.

Hi All,

Somebody was looking for iterative matrix routines written in C. I found
this on Programmer's Heaven. I'm not sure if they're iterative (I haven't
looked), but there's source code and all the good stuff (this is from the
newsletter):

- Algebra linear functions in language C.
-----------------------------------------
- A) Basic functions (use fractions) : addm, subm, multm, powm,
- smultm, transpose, trace, det, minor, cofactor, mcofactor,
- adjoint, inverse, gauss, gaussjordan. b) With random values. c)
- Save your work in a text file. math,algebra linear, matrix,

[Dev-C++] Difficulty compiling imported VC project file

[Strydom, J. (Jacques) <Jac...@ne...>]

Hi,

I have used the import function on dev-cpp to import a VC project file. When
I then try to compile fltk.lib, I get the following errors.

../src/Fl_x.o(.text+0x57d):Fl_x.cxx: undefined reference to `select@20'
../src/Fl_x.o(.text+0x5e3):Fl_x.cxx: undefined reference to `__WSAFDIsSet@8'
../src/Fl_x.o(.text+0x60f):Fl_x.cxx: undefined reference to `__WSAFDIsSet@8'

C:\Dev-Cpp\lib/libmingw32.a(main.o)(.text+0x7f):main.c: undefined reference
to `WinMain@16' make.exe: *** [fltk.lib.exe] Error 1 Execution terminated

My question is, do I have to do something else to the file before I can
compile it.

I have also tried to compile the program from the command line, but when I
type 'make',
I get an error, indicating that it cannot find 'touch'. Could someone please
tell me what this
is, and where I can find it.

As can be seen from the above, I am relatively new to C++ and makefiles.

Thanks for any help.

Re: [Dev-C++] WinMain@16

[Ricardo R. <ri...@po...>]

sorry Colin,

I have discovered the error,
with Allegro it is necessary to finish
the program with the line
END_OF_MAIN( );
after the end of the main program
...the secrets of programming !!.

thanks,
Ricardo.

Actually, it means, WinMain() is not defined. Ricardo has probably created a
GUI program with a main() function. To fix it, in Allegro, use
END_OF_MAIN(); after the closing brace of main(). Like this:

int main()
{
}
END_OF_MAIN();

Otherwise, change main() to WinMain(). However, retaining main() will be
more portable.

Re: [Dev-C++] class forward

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

Don't implement all code inline, it isn't a requirement as in Java.

Normally, you put most of your code in a cpp file, while the class
declaration and some small - very small normally - methods are inline in
the header file.

Class forwarding may only allow you to declare functions taking the class
as parameter - not to actually access the forward-declared class.

You may write:

class class A;

class classB {
private:
    classA *pClassA;
    classA &rClassA;

    // Forbidden - don't know size of classA!
    classA classA;

public:
    classB(classA *pClassA);
    classB(classA &rClassA);

    // Forbidden - don't know size of classA!
    classB(classA classA);

    void do_something(classA *pClassA) {
        // Forbidden - don't know interfaces of classA!
        pClassA->do_something;
    }
}

Re: [Dev-C++] WinMain@16

Hello,

This error means you haven't declared any main() or WinMain() function in 
your program. This function is mandatory when creating an executable, because 
it is the entry point of your program.

[Dev-C++] Newbie on debuggin again

[Lars-Bo J. <la...@fo...>]

Hi all

Still very new to Dev-C++ !

Does it matter how I set generation of debugging information?. It seems that
the executables are the same size no matter what I do to that setting. I use
version 4.9.7.4

Is this Dev-C++ specific or is it still a bug in gdb?

btw, anyone have experience with that sort of bug, How long time will it
take before the debugger works properly in Dev-C++. Just curios I am also
very new to open source and the GNU stuff.

[Dev-C++] use of cvs

[Jaap de W. <wo...@Ne...>]

Hello,

Any of you used the cvs option already?

At my place it does not work.
It's very basic: 
I can't login.
It asks for a password, I give the password, it asks again for the password,
and then I get:
Failed to supply password...

Of course from the commandline everything works fine.

Any suggestions?

Well, I have MinGW installed separately, and it's /bin directory is 
added to my PATH environment variable, and everything works fine.
Your problem happens, because the include files are not there, where gcc 
expects them to be.
My separate MinGW install has the following dirs:
/bin
/include
/lib
/doc
etc...

So gcc looks for it's DEFAULT includes in /bin/../include/stdio.h etc. 
It is it's default include searching path, but in Dev-C++ the includes 
are separated, and gcc cannot find them, unless it is explicitly 
specified. This is why even a simple "hello world" program needs 
explicitly set includes.
If this annoys you, I recommend you to download MinGW from
http://www.mingw.org
install it, and add it's /bin dir to your PATH. If you do this, you 
won't need to set ANYTHING at all, not even the exe paths, as they will 
be alway present.

Another solution would be to attach a config file to the
(Dev+MinGW together) release, where these includes are already set.
(Although it wouldn't be needed for the Dev only release).

This is my own guess.

[Dev-C++] Dev-CPP with Mingw

[<tim...@in...>]

I just started using the package, and I must say I'm pretty impressed so
far.  Very nice stuff in general.

However I have one issue that may or may not be a real bug, depending on how
you view it.  When compiling any C++ program, you have to add the mingw
directory to the include list manually.  This is probably because dev-cpp
tries to be compiler-agnostic, but since mingw is packaged in, it should be
reasonable to expect that you could build a small program right "out of the
box" so to speak.

As it stands, not even a "hello world" program will build unless you first
manually add the include/c++/mingw32 directory into the include search list.
I would call that a bug, although not a serious one.

[Dev-C++] access denied to my own variables? | access to bitmap bits

[<cg...@wo...>]

  Hi:
Now I'm practising with bitmaps and drawing. Things are going well (very 
well) except for this problem:

I call a function which creates a pattern brush, which bitmap is 
constructed on the fly based on the current selected color, it receives 
the HBITMAP and the HWND, the scrollbars position through a couple of 
int variables and the selected color.
In the main source I choose the color with ChooseColor function  like 
this (comments added in the mail):

        case ID_COLOR:
        {
        CHOOSECOLOR chc;
       
        ZeroMemory(&chc, sizeof(CHOOSECOLOR));
        chc.lStructSize = sizeof(CHOOSECOLOR);
        chc.hwndOwner = hwnd;
        chc.rgbResult = rgbCol;//Current selected color, its a static 
variable
        chc.lpCustColors = rgbCust;
        chc.Flags = CC_RGBINIT | CC_FULLOPEN;
        if (ChooseColor(&chc)){
        rgbCol = chc.rgbResult;//if success I change the current color 
and I change the current pen.
        logPen.lopnColor = rgbCol;
        }
        }
        break;

Then when I want to scroll the image and when calling that function, 
used when lbuttondwon either during mousemove or mouse still, but no 
other functions with same arguments than this. I got the errors 1400 
INVALID_WINDOW_HANDLE and 5 ERROR_ACCESS_DENIED.
It's like the HWND to the window gets invalidated, since when this 
happens then the mouse does nothing in the window and it has to be 
closed with the task manager.
Some times it only reports the error 5 the first time I try to use the 
brush function but then it works well again.
I did some changes, adding more GetLastError calls:
If I call the brush then I get the error 5 the first time and the brush 
is drawn, after hdc = GetDC(hwnd), and from that moment everything work 
again, if I try to scroll first the I get the error 1400 (I forgot say 
at the end of WM_XSCROLL I call a function for draw the image which 
receives the hwnd, hbm, scroll positions and which scroll changed.) and 
the window has to be closed through the task manager.
I don't see any difference with the win32api reference in the color 
selection code, and I don't kno how it could affect the window handle. 
Am I missing something?

The other question is how can I get the bits of the bitmap in a buffer??
I use GetDIBits but:
If I alloc memory for the buffer GetDIBits returns with 
NOT_ENOUGH_MEMORY  error, if I increase the memory allocated I only 
achieve having this error with GlobalAlloc, if I don't alloc and say, 
'perhaps it allocates itself the memory', it seems like it hasn't 
allocated memory and has not filled the buffer and when I try to access 
to the members I get an access violation (pvBits[n], pvBits is not a 
LPVOID, it is LPBYTE).
I want it for knowing the n-th pixel is of this color.
Where can I find examples of using Get/Set DIBits and CreateDIBSection?, 
what I find is using MFC, or source code with not enough explanations. 
So I can't see what I am doing wrong.
Thanks
