[Dev-C++] unable to run program file

[Ed C. <em...@ed...>]

Hi all -
=20
Does anyone know why I get an "unable to run program file" error when
compiling (with v.4.9.8.0)? This happens both with programs I've written =
and
with the examples.

[Dev-C++] how to redirect clog??

[Zodiaq <zo...@ac...>]

Yo all Dev-cpp users,

  got one simple question that I can't find cure for:
how to redirect clog for writing to file?? I tried creating ofstream
'over' a file, opening it for output and assigning it to cout - these two
are both of type ostream, but with clog "opernator =" is private, so I
can't use =. But there must be some way to change it (at least I hope
so), but how??

NO, it is a static library.

in that case, specify the DLL DIRECTLY with the

I noticed another DevC++ bug: when I override the build commands for a 
determinate source file (In projectOptions/Files tab), the directory 
path for such file is lost, causing a compiler error because the 
compiler cannot find it. So I have to specify the full path of the file 
in the overriding command.

RE: [Dev-C++] CStatic & memory

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

1) this is a dev-cpp list not a VC list. There are dedicated newsgroups for
VC.

2) The error you have is typical an error that happens when you write
outside 
your allocated memory. Eg if you have the following code:

int *pi = new int [5];
pi[-1] = 999;
delete [] pi;

will result in an error like the one you reported

Hmmm... did you send email to wrong mailing list, or am I missing
something here??! This list is about DevC++ and a little about MinGW
(compiler that DevC++ uses), so why did you send here question about
VC++ 6 and MFC?? MinGW uses WinAPI (or wxWindows) but not in any way
MFC (and that's what I love about it).

[Dev-C++] CStatic & memory

[pmeadlist <pme...@cl...>]

Hello, 

(error!):
Debug Assertion Failed!
File: dbgheap.c
Line: 1017
Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse) 

VC++6 gives the above error as I exit the app, otherwise app works ok 
without crash untill exit.
It only happens when I add a second CStatic control. I seem to only be able 
to have one CStatic control at a time. It does not seem to matter whitch of 
the two controls, but only one at a time. 

Do you want to see some code?

This was also the case for GCC (the compiler in Dev-C++) in older 
versions. I still don't know exactly why they introduced it. As I 
remember they have done this because of faster "parsing" of libraries: 
they only need to parse everything once, what was specified on the 
command line, so there is no need to go through all of them again to 
resolve remaining undefined references.
Anyway, this also has another (in my opinion) good side-effect: this way 
programmers cannot write cross-referencing libraries. (For example there 
is -lfoo and -lbar and both reference to each other). Oh well, they can, 
but then they have to give it on the command line twice:
-lfoo -lbar -lfoo -lbar
Which is ugly.

So keep it in mind: FIRST the library (OR object file, OR surce file) on 
the command line which USES the stuff, THEN the libraries (OR object 
files, OR surce files) which CONTAIN the stuff.

Well :)
This error caused me hours of swearing, until I realised that this is a 
BUG. Not always, but these errors are because of a 10 months old bug, 
which is not fixed, not matter how I write that f*ckin' bug-report.
Is tinyAudioLib a DLL? In that case, specify the DLL DIRECTLY with the 
libraries (full path!). This is really odd, I know, but in most of the 
cases, GCC tends not work correctly with import libraries, especially if 
they are C++. However, it works perfectly with the DLL directly. This is 
odd indeed.

Good luck!

[Dev-C++] word wrap for CEdit

[pmeadlist <pme...@cl...>]

Hi all,
I am using MFC to create a CEdit control.
I want the lines of text to wrap automatically.
Do I pass a param to CreateEx(...)?
Here is what I have at the moment:
this->m_wndEdit3.CreateEx(WS_EX_CLIENTEDGE,"EDIT",NULL,WS_CHILD|WS_VISIBLE|W 
S_BORDER|ES_AUTOHSCROLL,editDim3,this,IDC_EDIT3);
I thought that ES_AUTOHSCROLL made the text wrap?
TIA

You don't have to type class when declaring an object.
You must include the header file in the program you're building.
See below and at the end.

You should do:
File 1: header of test library, test.h
#ifndef TEST_H
#define TEST_H

class Test{
Test();
};

#endif

File 2: source file of test: library, test.cpp

#include <iostream>
#include <test.h>

Test::Test(){
std::cout << "This is a test" << endl;
}

Then you select both files into a static library project and compile it.
You build the library libtest.a.

After that you write your test program, test_program.cpp:

#include <test.h>
#include <stdlib.h>

int main(){
Test *test_object =3D new Test();

system("PAUSE");
return 0;
}
Then you compile it with the option -ltest for linker.

the file was well-compiled and generated a file called
libTest.a, wich I can add to the linker and use in
other program, but I have no Idea about how make a
reference of the methods.

I tried


#include <iostream>
#include <stdlib.h>

using namespace std;



class Test;
class Teste * test1;
extern Teste::Teste();

int main(int argc, char *argv[])
{
  teste1 = new Teste();  // <- the compiler points  me
an error here ... :(
  
  system("PAUSE");	
  return 0;
}

so, what´s goind wrong?
someone can help me?

thanks anyway,

[Dev-C++] using devcpp with different compilers.

[Gabriel M. <g.m...@in...>]

Hi all,
I'm asking if devcpp can be used as a front-end of mingw, cygwin, 
MSVC.NET free tools, Borland C++ and so on, at the same time and in the 
same machine, without need to reconfigure it each time I change the 
compiler brand. If it is not possible at present time, I really want 
such a feature to be implemented in the future. It would be a way to 
test the compilation of cross-platform code.

Re: [Dev-C++] Linking errors with winmme and dsound libraries.

[Gabriel M. <g.m...@in...>]

No Damien,
I succeded in making the program executable with the libraries re-built 
with devcpp. I also succeeded in making a program with a library built 
with MSVC (but not with such particular libraries, that contain calls to 
winmm.lib), so devcpp should be compatible with such libraries. I'm 
afraid that there are some incompatibilities with the winmm.lib provided 
by MSVC6 and the winmm library provided by mingw. I'm asking if such 
incompatibility could be avoided by some special command line flag or by 
  slightly modifying my code.

Thanks anyway for the answer.

[Dev-C++] builder and some WinAPI problem

[Jacek <mi...@wp...>]

Hi

I'm new here and I'm from Poland
I wanna know how can I show the process list on form in C++ Builder , I think 
I must use some WinAPI function but I don't know which.

Thanks a lot Jacek

RE: [Dev-C++] new is a wrapper around malloc so...

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

64-bit isn't just a speed issue :-)

Anyway, while most motherboards may only support 2-4GB memory, but the
386 processor isn't limited to 4GB physical memory, and some server
motherboards supports a lot more. However, with 32-bit paged memory
the machine may then run a number of applications each allocating 2-3GB.
But each individual application is limited.

There is a way around it. It's the dreaded 48-bit far pointer (16:32)
where the processor is supporting up to 65536 memory segments of up to 4GB
each. However, all programmers and compiler vendors have already learned
to hate the old 16:16 far pointers from 8086 (1MB) and 80286 (16MB) so
nobody is rushing for 48-bit pointers.

Segmented memory doesn't support or work very well with a number of
concepts we have learned to use and love with our current paged memory
model:
- On-demand allocation. Automatically grow the stack in 4kB increments
whenever needed.
- Memory fragmentation. In a paged environment, the OS may never get
fragmented memory, since each memory page is identical. It just keeps
track of a list of available pages, and maps in the first available page
when a process needs more memory. With segmented memory, the OS will
normally have to block the task and move the memory segments around in the
physical memory to get a continuous free block large enough for a memory
allocation.

Ahhhhhhhhhhh, so that's why everyone wants 64-bits. Games too are requiring 
more, probably because of the same memory-mapping issues.

RE: [Dev-C++] new is a wrapper around malloc so...

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

A 32-bit pionter is an unsigned entity, so it can span 2^32 bytes - 4GB.
From this address space, the different OS then reserves areas for OS code,
buffers, IPC etc. Depending on OS, you may normally not allocate more than
2 or 3GB for a single application.

This is the big reason why the world is so desperately wanting 64-bit
machines. In database solutions it is quite common to memory-map the
database files. However, 2-3GB is a puny database.

All I know is that the MSDN documentation I read says 2GB. I'm not sure
