To Ioannis,

Funny thing is I was reading an old Turbo C reference guide I have lying
around that mentioned linking Turbo C and Turbo Fortran (was it called
that?). Borland seemed to very proud of this cross language linking. There
are some difficulties with function name decoration and what-not that you
need to be aware of. I can't quite recall what they were, but I'll try to
remember to take a look this evening.

I'm not sure if the same advice will apply here since it is clearly
different compilers, but it may give you an idea. I'd still look on the net
for info specific to the compilers you want to use.

To Per,
Is there anything you don't know anything about? (LOL).

I don't recall if the above mentioned book mentioned any difficulties with
multi-dimensional arrays. Besides, as far as I'm aware, C uses arrays of
arrays and not multi-dimensional arrays, so would the trick not be to set
your arrays up in the same way that Fortran does?

I think there might be acoule of gotchas more to think about.

Doesn't fortran have the reversed row/column order for multi-dimensional
arrays?

Anyway, I assume that there already exists excellent FAQ documents for this
kind of problems.

You want a *.a library file, not a *.lib library file.

Anyway, this isn't a problem, since you are not going to build wxWindows
with Dev-C++, but with your MinGW compiler. There are already working make
file for use with the MinGW compiler, so you will build from the command
line.

If you do download the wxWindows source, there is an excellent document
describing the few steps you have to perform, to configure the wxWindows
build environment, and perform the build on a Windows platform.

I do not remember anything from Fortran except that it allows for
counters in loops i, j etc.. But what you mentioned sounds like a syntax
issue rather than an implementation issue.

Thanks Per,

Its what I suspected ..
Another question (this could seem stupid, and probably is, but I'm not very 
at ease with this building stuff).

Can I build 2.3.3 (or any other release) with Borland C++ 5.5 (free command 
line tool) and use the result with dev-c++ ?

(the reason is that Borland C++ was the first compiler that I set up when I 
was looking for a compiler to learn C++, and I have it set up correctly and 
running, but I prefer by far Dev-C++)

Since your include file - Control.h - doesn't contain any implementation
of OnInitPopup, you have to locate a source (*.cpp) file that contains the
implementation, or an object file or library that contains the method.
Add this source/object/lib to your project.

wxWindows stable is 2.2.9

The 2.3.3 version you have seen is a development version. If you wan't to
use versino 2.3.3 you have to download and build a library yourself, and
then set Dev-C++ to use the new library and the new include files.

Well if you download the whole MINGW distribution it contains a Fortran
compiler. In theory as i can think of it, if you compile your fortran
source code files to .o files and use C-style declarations of those
functions in your C source code, you should be able to use them.

Hello,

I downloaded wxWindows package and the install works like a charm (Dev-CPP 
4.9.6.6).
The only problem is that the packaged version is 2.2.9 and now wxWindows is 
currently in version 2.3.3.

How can I update my setup (without breaking anything) or How can I make a 
package?

Thanks in advance

Luc

And besides, the function prototypes below are of the normal fortran
quality, since - at least for all old fortran standrds - the language
haven't been known to support very long symbol names. I'm a but rusty, but
isn't it somewhere around 6 characters that's the limit?

There isn't many people tht would call Fortran code beautiful, but that's
the language.

How easy is it to write code to monitor ports? Say you wanted to watch what 
was happening at port 80 (which is where http packets are retrieved 
(correct?)) would it be easy for an intermediate programmer? Would it 
require many hours of work? Could you set up a text file to store activity 
and then look at it after?

I've not done anyhting like this before so any advice would be great. I'm 
just interested to know that's all.

Daniel

LOL oh yes! Quite right, I apologise. Still, in my browser it looks a little 
difficult to read.
It's early here lol. Once again sorry about that.

I have install dev-c++ on win2000 and works ok. I have tried to install it
over Linux (mandrake 8.2) and I cannot make it work.
The installation goes OK. Then I execute the file devcpp (I think that is
called like that) and nothing happens. I execute a "ps" Unix command (ps
-ef|grep devcpp) to see if the process was created, and it was. I think that
I miss an X module to display the application.
Please does anyone know what is going on?

thanks 

Fernando

Well. . . there wasn't any 'code' in my message, just a sketch of the
fortran subroutine prototypes I'm trying to call from c.  If you read my
message, you'll note the source of the 'code' is an existing numerical
package.  The author's standards of variable naming/white space use are of
little concern to me and certainly have nothing to do with the question
posed.

Sorry, I've been reading Code Complete recently. Excellent book - by Steve

Put restriction on your interface and you can use windows groups and 
what ever you wan't.

i don't know but you can use any ide that know COM like borland 
c-builder Delphi i think you can use borland compiler (i nerver tied) 
and of course VC ++ ($$$$)
Sorry if my answer is not such explicit in how to do it.There are a lot 
of tutorials on web so you can use abny of them.

 which i posted and was advised to make sure that the file defines the
flaged functions are added to the project. This I have checked and
seems to be okay. In fact the functions in question are defined in
Control.h which in turn is included in Ctrl.h. Below is the content of
Control.h.

#if !defined (CONTROL_H)
#define CONTROL_H

#include <windows.h>
#include "Window.h"
#include "Procedure.h"

namespace Win
{
	class Controller
	{
		friend LRESULT CALLBACK Procedure (HWND hwnd, 
						UINT message, WPARAM wParam, LPARAM lParam);

		void SetWindowHandle (HWND hwnd) { _h = hwnd; }
	public:
		virtual ~Controller () {}
		virtual bool OnCreate (Win::CreateData const * create, bool &
success) throw ();
		virtual bool OnDestroy () throw ()
			{ return false; }
		virtual bool OnMouseMove (int x, int y,	KeyState kState)  throw ()
			{ return false; }
		virtual bool OnInitPopup (HMENU menu, int pos) throw ();
	protected:
		HWND  _h;
	};
}

#endif

I still however have the same error as above. I'll appreciate your help
 please.

I am trying to get my first WxWindows application started.

The first thing I wanted the program to do was display a "splash" screen ala
windows...

The compiler said I was missing wx/splash.h and indeed I am...

I downloaded the WxWindows DevPak via the check for updates in Dev-C++.  Am
I doing something wrong here???

Thanks in advance...

It would be nice ... 

I use Mingw compiler.

Thanks,

Hi,

Wondering if anyone has experience with mixed language programming and
whether it can be done with Dev-Cpp?

In particular, I'm writing a mathematical simulation in C (using Dev-Cpp)
and would like to make using of some existing numerical routines in Fortran.
My C knowledge is necessity-based self-taught and so limited; don't know
anything about Fortran.  Neither do I know much about using
compilers/linkers/etc in command line mode (which is why I use Dev-Cpp--I
let it worry about that stuff).

Still, I know that built-in to the gcc interface is the g77 compiler so
there must be a way to compile the fortran source to an object with g77 and
then link to & call the routines from C.  Could it be as simple as added
fortran source files to my Dev-Cpp project?  If so, any thoughts on how to
prototype the Fortran functions & subfunctions to make them accessible to
the C calling routines?

BTW, I've tried f2c but have been unable to make that work.  That approach
is suboptimal anyway because the resulting C code is far less efficient than
the original Fortran source.

Perhaps specifics would help.  The fortran code I'm trying to use is a
single file ode.f  The entry point is the subroutine ode.  Here's how the
file is laid out:

// ode.f

      subroutine ode(f,neqn,y,t,tout,relerr,abserr,iflag,work,iwork)
      implicit real*8(a-h,o-z)

c      f -- double precision subroutine f(t,y,yp) to evaluate
c                derivatives yp(i)=dy(i)/dt
c      neqn -- number of equations to be integrated (integer*4)
c      y(*) -- solution vector at t                 (real*8)
c      t -- independent variable                    (real*8)
c      tout -- point at which solution is desired   (real*8)
c      relerr,abserr -- relative and absolute error tolerances for local
c           error test (real*8).  at each step the code requires
c             dabs(local error) .le. dabs(y)*relerr + abserr
c           for each component of the local error and solution vectors
c      iflag -- indicates status of integration     (integer*4)
c      work(*)  (real*8)  -- arrays to hold information internal to
c      iwork(*) (integer*4)    which is necessary for subsequent calls

. . . ode calls de:
      subroutine de(f,neqn,y,t,tout,relerr,abserr,iflag,
     1  yy,wt,p,yp,ypout,phi,alpha,beta,sig,v,w,g,phase1,psi,x,h,hold,
     2  start,told,delsgn,ns,nornd,k,kold,isnold)
      implicit real*8(a-h,o-z)

. . . de calls step & intrp:
      subroutine step(x,y,f,neqn,h,eps,wt,start,
     1  hold,k,kold,crash,phi,p,yp,psi,
     2  alpha,beta,sig,v,w,g,phase1,ns,nornd)
      implicit real*8(a-h,o-z)

      subroutine intrp(x,y,xout,yout,ypout,neqn,kold,phi,psi)
      implicit real*8(a-h,o-z)
// end ode.f

The derivative function f is written in C (and that's where I was having
probs with the f2c route).

All help is appreciated (sorry for the long post).

Scott

Yes, perfect both methods and the solutions suggested. Thank you. The cla=
ss side, that
is, when the access to the fuction members of the class is made, it is we=
ll defined.

Now I'm thinking in a way to discover whose program is accessing them (th=
e classes).

In a Unix world I could check the gid and discover which kind of user pro=
gram is
requesting it.
And in a Win environment?

Are you understanding now? How can, in a run-time mode, I can check this =
access

Hello Cesare,

to use the serial ports with DevC++ depends on the compiler to use
with.
As far as I know (but I'm not sure) with borland these functions are
included 
in the conio.h.
There is also a conio.h that comes with the DevC++ IDE written by
Hongli Lai but I don't know whether it will compatible with borland.

I use the cygwin system because of the ability to port these
applications to unix systems.
With cygwin the required funktions are in termios.h and fcntl.h

If you are interested in I can send you a little example that uses the
cygwin system.

Greetings

Frank

>>> Cesare Padovani <pad...@in...> 10/29 1:10  >>>
Does anyone know how to write to and read from an i/o port?

In the dos version of Borland C++ there were the functions:

void outport(int portid, int value);
int outp(int portid, int byte_value);

located in dos.h.

What about Dev-C++ in this area?

Regards, Cesare Padovani

I'd considered derived classes as a solution, but I think perhaps the 
exercise (it sounds like one) involves creating a portable class - one that 
can be plugged in to a project.

The variables specified could have been anything, so we're not sure on 
whether our solutions are going to work or not. The functions are not 
specified so they could do anyhting. I thought setting access via the 
constructors would work better. After all, if the object was to derive the 
class into child classes the exercise would have said so surely?
