[Dev-C++] Debug breakpoint editor bug?

[Omar B. <oba...@gm...>]

Hello, I was debbugging an application when noticed this (which IMO is one)
bug:

In summary, when you set a breakpoint in a line n, and after that you edit
some code before that line adding new lines the breakpoint toggled before
stays in the same line number (line n), not mattering if the actual statmen=
t
that was at line n before editing the file moved to other line.

Although it clearly seems to be an expected behaviour in the editor I
*think* it should not work that way no?, isnt the expected behaviour for th=
e
breakpoint to move with the statement?

cheers,

Omar.

Re: [Dev-C++] linking error in vc++

[<ind...@gm...>]

Dear Bhadram,

I am writing to you in response to your mail to the Dev-C++ user list.

 > Dear friends,
 >        I'd problem in vc++. The problem is i want to call the static

the problem you encountered is due to the fact that in this case, the
_word_map member of the class UserQuery is just the declaration, not the
definition.

The solution to that would be to create a new file, UserQuery.cpp, and
include following lines:

UserQuery.cpp:
#include "UserQuery.h"

map<string,vector<Location>*,less<string> >* UserQuery::_word_map = 0;

You could even leave out the '= 0', the only important thing is that
the symbol _word_map is DEFINED in a COMPILATION MODULE (which a
header file is not).

Hope that helps,
   Yours,
      David.

Re: [Dev-C++] override the debugger run command-line

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

Hi BR,
 
I've a similar problem developing a plug-in for GIMP.  Though it produces an executable, the executable is not standalone and must be called through GIMP.  Hence, I can use gdb, but with a slight modification to the code to allow for attachment through gdb once the plug-in is active.
 
In the h file, I place the following:
static gboolean d_l = true;  // Debug loop exit test flag.
static gint32 d_v = 0x55AA55AA; // Dummy variable to allow the debug routine something to do.

 
Then in my main code I place the following:
 // Debug wait here.
#ifdef DEBUG
 do {
  shapefs.d_c();
 } while (d_l == true); // Make this variable false to continue with program flow.
#endif

 
Then I create a procedure called d_c():
void GIMP_SFS::d_c (void)
{ /* If DEBUG is defined, will loop in this function forever until attached by
    the debugger and the value d_l set to false.
 */
 d_v = ~d_v; // Just something to do.
}

 
I start the debugger and place a breakpoint at GIMP_SFS::d_c.  When the plug-in starts, it is stuck executing the do loop.  I then use the gdb attach command to attach the PID of the plug-in.  Continuing with the gdb c command, it stops at the first breakpoint at GIMP_SFS::d_c.  Then I execute the set command: s d_l=0, then continue the application, using appropriate breakpoints as necessary.
 
This may not answer your question correctly, but shows an alternative method to debugging an otherwise undebugable program.

Re: [Dev-C++] accessing derived class methods

[Richard M. <mu...@cs...>]

This is straightforward C++.  The base class pointers can only accesses 
those functions defined in the base class.  If you want to access stuff 
unique to specific type of employee you'll have to make sure those 
pointers are, indeed, to that kind of object.  Which you can't know 
ahead of time if all you have is a pointer to the base class.

Getting those pointers is another issue.  You can always do one of the 
various casts, in your case a dynamic_cast is probably the right thing, 
but this is chancy.

The trick is to design your employee base class so that everything you 
need to do in terms of interface is defined in the base class.

Your comments are encouraging. I will read up on dynamic_cast<type>

Thank you.

Re: [Dev-C++] accessing derived class methods

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

There are solutions to everything. The problem is just to know when the
solution should be used, and when a program should be written in a
different way.

using dynamic_cast<type>(object) you can type-safely convert from a base
class pointer to a pointer for a derived object. If the object isn't a
derived class, then you will get a NULL pointer instead.

Neeraj,

Thanks for the input. I was afraid of that. I suppose this holds true  
always. I was hoping that a nested class with some friend

[Dev-C++] accessing derived class methods

[Dane E. <dg...@wo...>]

Hi all,

I have a simple base class and a few derived classes from it. My goal  
is to build an array of pointers where I can assign derived class  
objects into, then access the different derived class attributes
as needed.

So I have an employee class. I derive a laborer, scientist, and  
manager class from it. I build some basic virtual functions in the  
employee class, and each derived class
has a couple of specific attributes that I want to call, like  
getSpecificData().

I made an array of base class pointers then tried accessing the  
derived class methods, but it doesnt work. I made an array of void*  
pointers and tried to access derived class methods and that doesnt work.

I realize that I could build a pure virtual function in the base  
class that would only be used to access derived class atrributes, but  
that is silly. Please can someone point* me in the right direction?

Thanks for any help you can offer.

Best regards,

Dane

Re: [Dev-C++] trying to open a specific folder

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

Try downloading the source code for File_Cleaner at http://www.geocities.com/alreaud/FileCleaner/FileCleaner_1.0.1.3-20041209.zip
This is an example of searching, opening, and writing/deleting files when you don't know the file names and some folder names to start.  Use freely as it is distributed under the GNU-GPL Ver. 2 license.

Re: [Dev-C++] undefined reference to all ODBC API functions

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

Hi Waseem,
 
I come across this kind of problem all the time in my own applications.  My solution to find the correct library to link is to use a text search application such as grep.  Then I execute
cd ~/dev-cpp/lib
grep -i -r  'SQLAllocEnv' * (FINDSTR in DOS/Windows I believe).
 
The results of this are pasted into the Project Options --> Parameters --> Linker window in the form:
-lSQL_Library
where SQL_Library is the correct library name, sans the extension.  As example I am working on a GIMP plug-in.  One of the required libraries is gimp-2.0.lib.  It's entry in the Project Options --> Parameters --> Linker window is:
-lgimp-2.0
 
Have a great weekend!

Standard C++ doesn't have a library for manipulating directories. The
closest thing you can get is Boost's filesystem library. However, most
implementations nowadays support the quasi-standard <dirent.h> and
<dir.h> libraries. These libraries, originally written in C, enable you
to list the files in a directory, change the current directory, create a
new directory and delete an existing directory.

#include <errno.h>
#include <dirent.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
 DIR *pdir;
 struct dirent *pent;

 pdir=3Dopendir("."); //"." refers to the current dir
 if (!pdir){
 printf ("opendir() failure; terminating");
 exit(1);
 }
 errno=3D0;
 while ((pent=3Dreaddir(pdir))){
  printf("%s", pent->d_name);
 }
 if (errno){
 printf ("readdir() failure; terminating");
 exit(1);
 }
 closedir(pdir);
}

Re: [Dev-C++] undefined reference to all ODBC API functions

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

The normal suggestion: Make sure that you are linking your application
with the required library. Header files are just an index of available
functions - just like the telephone catalog. They make the compiler happy.
Next step is to make the linker happy.

[Dev-C++] make not in bin path...

[Richard M. <mu...@cs...>]

I have a MinGW installation that works (make is there, builds programs, 
etc.).  I'm using MinGW Developer Studio and want to try Dev C++.  I 
installed DC++, pointed the binary paths to where I had installed MinGW, 
no joy, the error continued.  I tried putting MinGW in the PATH search 
list, still no joy.  I installed the full DC++ and now I could compile, 
but anytime I tried to debug things, I was asked to switch setting to 
debug and do another compile, which didn't generate any compile information.

So clearly I'm doing something wrong, but I can't figure out what at 
this point.
