Re: [Dev-C++] MySQL Link error

[<gui...@ya...>]

Hi Per, 

yes in fact I was making a mistake with the linker, so I added
"-lmySQL" and allso compiled the example, and this is what I get:

-------------
Compiler: Default compiler
Building Makefile:
"C:\Dev-Cpp\Examples\MySQLClientTest\Makefile.win"
Executing  make...
make.exe -f "C:\Dev-Cpp\Examples\MySQLClientTest\Makefile.win"
all
g++.exe -c MySQLClientTest.cpp -o MySQLClientTest.o
-I"C:/Dev-Cpp/include/c++"  -I"C:/Dev-Cpp/include/c++/mingw32" 
-I"C:/Dev-Cpp/include/c++/backward"  -I"C:/Dev-Cpp/include"  
gcc.exe MySQLClientTest.o  -o "MySQLClientTest.exe"
-L"C:/Dev-Cpp/lib" -lmySQL 
MySQLClientTest.o(.eh_frame+0x11):MySQLClientTest.cpp: undefined
reference to `__gxx_personality_v0'
make.exe: *** [MySQLClientTest.exe] Error 1
Execution terminated
-----------------

Could this be a problem caused by the warning in
http://www.bloodshed.net/dev/devcpp.html?

" /!\ WARNING /!\ : Due to changes in the C++ ABI in GCC 3.2,
some of the available Dev-C++ Packages for the C++ language will
not work. Please read this for more information. "

Re: [Dev-C++] Input line too long while linking

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

Change to NT/2k/XP to get longer command lines.
Check if you can move source and/or include files to get shorter paths.

You should include file
<projectname>_private.h

There are defined (#define) consts about major, minor and build number

for example:

#define VER_STRING "0.0.0.37"
#define VER_MAJOR 0
#define VER_MINOR 0
#define VER_RELEASE 0
#define VER_BUILD 37

[Dev-C++] about gcc

[mctimes <mc...@21...>]

Hi all,
  The current release of devcpp is only support gcc 3.2. However, the
newest version of gcc is 3.3.x. Accordingly to the documentation of gcc,
some new features will only found on 3.3.x, I wonder why devcpp don't
upgrade the compiler to the new version ????

[Dev-C++] Version info

[Paul S. <su...@po...>]

Is there anyway to include the version info (in the project options) into my
code at compile time?

i.e.
I want my application's title bar to contain the major,minor and build
number.
Are there any special preprocessor directives that I can use?

It's a pain having to copy it every time I do a build and it's too easy to
forget
to update.

Thanks
Paul

Re: [Dev-C++] Directx 9 - DirectSound problem

Hello,

 Thanks for response.

 I got it:
 The third parameter was wrong, should be:
  LPDIRECTSOUNDBUFFER lpDSBuffer;

  IDirectSound_CreateSoundBuffer( lpDS, &dsbd, &lpDSBuffer, NULL );

 I still don't know what doesn't it compile without modyfing dsound.h and
mmsystem.h. do you have the same problem?

 Thanks,

Re: [Dev-C++] Directx 9 - DirectSound problem

[Daniel G. <sp...@ho...>]

I think I see a problem,

IDirectSound_CreateSoundBuffer( &pdsbuffer, &dsbd, &pdsbuffer, NULL );

why is there an underscore therE?

and secondly (important) you must get a pointer to an interface and then use 
that pointer to access the interface functions.

Try that and see if it helps.

Re: [Dev-C++] Get socket with socket function

[Reid T. <rei...@at...>]

My opinion differs.  I am only offering an alternative that may provide 
alain the means
to get the end result he wants w less code modification.  I imagine he 
could as easily configure
Dev-C++ to use borlands compiler/libs/dlls.  His choice.  But,
I have no issue with my application utilizing the cygwin dll.
In my opinion, cygwin more than makes up for that by:
  providing a posix/linux/unix env to work in
  providing ~all the tools of a *nix environment
  allowing me to run any Xwindows client i desire
  providing me the ease to take most any *nix source code download &
     untar it; type ./configure; type make; type make install and be 
done w/o
     having to re-write the code
   providing me the ease of use to move code that I am working on from 
*nix to
   Win* and back.
   etc, etc

how do you define native code?
The cygwin dll( c code compiled on windows to run on windows) is as 
native as any of the mingw .dll/.a files.  And they (the mingw files) 
are 3rd party libs.

RE: [Dev-C++] Get socket with socket function

[P.D. v. Z. <pa...@my...>]

But your application will be dependent on the Cygwin DLLs, which can be a
nuisance. I always prefer native code over emulation, especially when the
emulation requires 3rd party libraries.

	Hi all, 


	I managed to compile a simple program that should just wait for an
icoming connection on a inet type socket. I did it under Mac OS X and Linux,
and I want to do the same thing with dev-cpp. 


	Due to explanation give on this mailing list (thanks for your quick
and usefull answers), I change the code to use winsock.h instead of
sys/socket.h. I added the necessary library and DLLs. The program starts
correctly and get it the function to create the socket file descriptor (it
is very simple) : 


	int sockfd; 


	sockfd = socket(AF_INET, SOCK_STREAM, 0); 


	BUT the result of socket function is always -1 (sockfd = -1). What
could be the cause of that ? I found a similar example of socket creation
for windows, I did exactly the same as in the example. The only thing I have
found in "socket" man page is : 


	"A -1 is returned if an error occurs" 


	But how can an error happen at this step ? 


	Thank you for any advice. 


	Best regards.

Re: [Dev-C++] MySQL Link error

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

Where did you inform DevC++ that you wanted to link your application with
the mysql library? From the compiler output, you can see where the linker
looks for libraries (-L"C:/Dev-Cpp/lib"). However, that is not enough. You
also have to tell it which extra libraries you need, such as -lmySQL.

Did you try c:\Dev-Cpp\Examples\MySQLClientTest?

Re: [Dev-C++] Dev C++ references

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

There are no Dev C++ Implemented Basic Library, since Dev C++ isn't a
compiler but an IDE.

Check out MinGW (the used compiler), gcc (which MinGW is based on) or
Microsoft MSDN - since you are programming on the Windows platform.

Re: [Dev-C++] Missing main() !

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

The main() is hidden inside windows libraries. Your application will start
with WinMain() - or DllMain() in case of a DLL.

[Dev-C++] Missing main() !

[Roger C. <rc...@ic...>]

Dear fellows,

I runned the API examples WinTest and WinMenu that come with Dev C++ (folder
Dev-Cpp\Examples\) with absolute sucess. I could notice that there is no
main() start function in these programs. I would like to understand how can
a C/C++ program have no main(), or start point or where is it in these
examples.

Thanks for your help

Is there a good reference to use with Dev C++.

[Dev-C++] Get socket with socket function : precisions

[Alain P. <ala...@ge...>]

Hi all,

I noticed that the errno value doesn't seem to contain the last error. 
So I used WSAGetLastError() function to retrieve what happened when 
using "socket" function. According to results (WSANOTINITIALISED), it 
seems that I have do initialize something when working with socket 
under windows. This makes, of course, code less portable due to 
specific Windows initialisation... But OK, I did initializsation. The 
problem is that now, the error is "WSAEAFNOSUPPORT". Is there so many 
differences between linux and windows when creating a socket ? Does 
soemone use inet sockets under dev-cpp and have a simple example ?

I am under Win 95 (pretty old, I know...). Perhaps do I ask my 
questions to the wrong list (as my problems are not dev-cpp specific 
problems). If this is the case, can someone propose me a list where 
these questions will better match lists topic ?

Best regards.

[Dev-C++] Directx 9 - DirectSound problem

[Marek <sp...@we...>]

 Hello,

 I'm trying to play sound from a C program using DirectSound ( Secondary
Buffer ) and I'm getting an error:
109 dxsound.c structure has no member named `CreateSoundBuffer'

 piece of code is: 

#include <windows.h>
#include <mmsystem.h>
#include <dsound.h>

[...]

 IDirectSound pds; /* DirectSound object */
 IDirectSoundBuffer pdsbuffer; /* sound buffer */

/* initialization of DirectSound, CooperativeLevel etc. */
  /* create wave format description */
 memset( &pcmwf, 0, sizeof( WAVEFORMATEX ) );
/* filling the values */
  /* create sound buffer description */
  memset( &dsbd, 0, sizeof( DSBUFFERDESC ) );
/* filling the values */

 IDirectSound_CreateSoundBuffer( &pdsbuffer, &dsbd, &pdsbuffer, NULL );

does anyone know the solution to this? I can send the entire unit if needed.


Also when I tried to compile I was getting duplicate definition errors between
dsound.h and mmsystem.h.

The changes I had to make were:
in mmsystem.h
line 1008:
change
#ifndef _WAVEFORMATEX_
#define _WAVEFORMATEX_
to:
#ifndef _WAVEFORMATEX_
#define _WAVEFORMATEX_
#define _LPCWAVEFORMATEX_DEFINED

in dsound.h
line 1899:
change:
typedef struct IDirectSoundFullDuplex *LPDIRECTSOUNDFULLDUPLEX;
to:
//typedef struct IDirectSoundFullDuplex *LPDIRECTSOUNDFULLDUPLEX;

Am I missing something?

Thanks in advance,
Marek

Re: [Dev-C++] Looking for a good tutorial

[Daniel G. <sp...@ho...>]

Controls are windows, but they look different (you can get a handle to a 
control like you can to a window).

I'll keep an eye out for any tutorials, you might want to try a google or 
yahoo group for windows. msdn.com may help you too.

Link the appropriate libraries :P
I believe you need libws2_32.a (if I guess correctly from the name I used to
use in VC++... ws2_32.lib).

Subject: [Dev-C++] Linker problem

Hi all,

I just redo my program to use winsock.h instead of <sys/sock.h>. Now, the
header is found, and there is no compilation problem. But the linker can't
find the functions I use (like "socket", "htons", "bind", etc.). This means,
I suppose, that at least one library is not found by the linker (message :
"Undifined reference to socket@12"). What should I do so that the linker can
find the necessary functions ?

Thank you for any help.

RE: *****SPAM***** Re: [Dev-C++] implicit declaration

[P.D. v. Z. <pa...@my...>]

"Effective STL" is a book in the Professional Computing Series, by Addison
Wesley. I don't have the book myself, but I do own several other similar
books (some in the same series)... (Effective C++, More Effective C++,
Exceptional C++, More Exceptional C++, C++ Gotchas)... these books address
specific issues on an item by item basis. I still have to buy Effective STL,
so I can't really help you with the contents of Item 5, but I'm sure someone
else here owns the book and can tell you what Item 5 is about :)
