Re: [Dev-C++] flushing buffers

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

Please enlighten a novice: How can it be guaranteed that you can mix two
different IO libraries and still get 100% function?

Please _do not_ use both IO libraries for input from same stream.

Flushing output is a performance loss but works. No characters gets lost
and the flush solves the problem with output through the two libraries
getting incorrectly mixed with each other.

Flushing of input is a lossy project - throwing away characters. You just
can't throw away characters eaten by one IO library and then expect the
other IO library to not be affected.

In some special circumstances you might get a program to work with a mix
of C and C++ input from the console. However, if you change to another
compiler or move the code to another OS, you don't know how your program
will behave. Different implementations of the libraries behaves
differently. However, this isn't a problem: If you use just C or just C++
for a specific stream, you are using the libraries as they are indended,
and then they will behave as expected.

The problem is similar to trying to set output position of a file with
fseek(FILE*,...) and then use a output stream to write information. The
output stream doesn't know about the fseek() and the output gets written
to the wrong location.

If we think about standards: The C++ standard can't have full control over
the internals of the C library, while the C standard obviously haven't any
control over the C++ libraries.

So, I repeat it once more: Avoid mixing getche() with cin!

In a win32 console, you can always use SetConsoleMode() with the
ENABLE_ECHO_INPUT flag to control input echo.

[Dev-C++] flushing buffers

[Noorez K. <dar...@ho...>]

How do I flush the input buffer after using getch() or getche()? I use 
cin.sync() after using cin? How can I do it for the other functions?

Re: [Dev-C++] Error Messages

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

1) The complete error messages are:
fnkptr.cpp:29: error: assuming pointer to member `void Dog::Speak() const'
fnkptr.cpp:29: error: (a pointer to member can only be formed with `&Dog::Speak() const')

Just add a & before eacn function name, just as the error message suggest,
and the compiler will be happy.

2) Notice that Dev-C++ is an integrated development environment, not a
compiler. It is the gcc team - or possibly the MinGW team - that is
responsible for which error messages are emitted by the compiler. By the
way, 99.9% if the error messages I have seen have been quite obvious.

3) windef.h is a file seldom directly included in a program. However, a
number of other include files recursively requests the windef.h file. If
you check again, you should be able to find out why the compiler mentioned
it. The compiler never makes this kind of mistake. The only reason it said
BOOL was already defined in windef.h was that the program directly or
indirectly did include windef.h

[Dev-C++] Error Messages

[Roger F. <ra...@ha...>]

Aloha from Honolulu,
   The following was taken from Sams Teach Yourself C++  and refuses to 
compile.  The compiler reports the error at the line following 
"Dog::PlayDead" which is the closing brace and semi-colon for the "PDF 
DogFunctions...".  I have marked it with an exclamation point ! here.  
While I do need to know what the code's problem is, more vexing is that 
in the compiler report window under messages is listed "assuming" and on 
the next line "(a".  Nowhere have I been able to find a list of the 
various messages.  I looked under the Help window of the program 
(Version 4.9.8.0) and also on the Bloodshed site, but no luck there 
either.  I would suggest that a comprehensive list of error messages 
would benefit most everyone using these programs.
   A further note: earlier in the lesson was a line: enum BOOL {FALSE, 
TRUE};  that generated the folowing error messages: "conflicting" and 
then: (copied from the compiler report window)
227 C:\Dev-Cpp\include\windef.h   previous declaration as `typedef 
WINBOOL BOOL'
   My solution was to comment it out, but why did the message appear 
when windef.h was never included in the code?
Thanks in advance,
Mahalo,
Roger

simply drop the 'using namespace abc;' statement. you have no reason to 
use it in your example. anything in the 'namespace abc {' block 
automatically uses the namespace.

Re: [Dev-C++] errors with i/o

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

So the reason you never give feedback to received answers - you never read
them...

Be _very_ careful about mixing FILE-based and stream-based input and/or
output to the _same_ stream, since the C library and the C++ stream
library have their own input/output buffer code. When mixing them, serious
problems with interaction may/will follow. Regularly flushing the streams
may help the problem, but the best solution is to not mix the two
input/output methods!

I am getting some very strange results with my program. The first error is 
that the input on the marked line, shows up on the next input line but has

line acts as if there was an input on each round of the main loop. If the 
answer was 'n' it only skips once.

Re: [Dev-C++] How can I use OpenGL GLUT? (the story of a confused user)

[Gustavo L. <gl...@qa...>]

There is a free version of glut: freeglut. It cames in a devpack so you can easily install and use it.
You can download it from: (http://devpaks.org)

Re: [Dev-C++] How can I use OpenGL GLUT? (the story of a confused user)

[Martin O. <li...@mi...>]

The problem with that is that the latest GLUT (3.7.6) has a header file 
that works only with non-free products. Additionally I use -Wall and a 
few other such flags and in total there is about 1 page full of 
warnings. There is however only only fatal error in the latest glut.h 
(something about redefining some *CHAR* type.

In general alot of .h files seem to give me strange errors in dev-cpp 
but they work out fine in MSVC. This makes be feel that dev-cpp is a bad 
product, and I would really like to change that because I prefer free 
software.

martin

I too couldn't find the header. So I simply used the header that GLUT 
comes with when you download it.

[Dev-C++] How can I use OpenGL GLUT? (the story of a confused user)

[Martin O. <li...@mi...>]

Hi,


I'm having difficult understand how to use GLUT from the dev-cpp 
platform. My first try was to download GLUT for win32, but I noticed 
that dev-cpp could not use the MSVC .lib file. I googled for awhile and 
then I learned about reimp.exe and I used to to get a proper .a file for 
dev-cpp. However, when I was about to copy the new .a file into the 
dev-cpp lib dir I noticed that it already had a libglut.a and also an 
existing copy of libglut32.a. I thought, strange, and so I reported this 
as a bug because there was no .h file only a file in the lib dir. Then I 
googled some more and I found a reference to freeglut which I thought 
was a great idea. Hence I arrived later at the freeGLUT homepage, here:

http://www.nigels.com/glt/devpak/

Now it says "No longer needed, GLUT is now bundled with Dev-C++", but 
what does that mean? I'm really confused, if GLUT is indeed bundled with 
dev-cpp maybe one could add a GLUT project template right besides the 
OpenGL-project thing? That would simply ALOT for confused people like me!

---

Finally, what is the best way for me to proceed? Is there a preinstalled 
GLUT library+header set somewhere on my computer (im using the latest 
dev-cpp as of today). Where can I find it, how can I use it?

Re: [Dev-C++] (no subject)

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

Have a look at Makefile.win - or the compiler output tab when building a
project - and you will see the command used for compiling the resource
file.

It is using the windres.exe program that is supplied with the compiler.

Re: [Dev-C++] Using Namespaces

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

About playing a bit with project settings etc. Am I the only one who use
to add extra rules to the Makefiles?

I always add 'include pwm.mak' to the Makefile.win, where this file
contains (among other things):

depend:
  $(CPP) -M $(CXXFLAGS) $(OBJ)

include .depend

This allows me to use Makefile.win externally or with "fast but imperfekt
dependancies" in Dev-C++ and just manually run 'make depend' when I know
that I have added more #includes to some source file. It also makes sure
that changes to system include files (<>) results in recompilation.

When running with large projects, running without "fast but imperfect
dependency generation" takes very long time while the files are scanned
before compilation, and having it checked regularly produces strage errors
when too few source files have been recompiled.

[Dev-C++] Making "lib" files

Hi everyone,
I want to know how I can make a “lib” file (e.g.
“mylibrary.lib”) and how use it in my programs.
Thanks,

Re: [Dev-C++] Using Namespaces

[Hielke <hie...@he...>]

AFAIK there is no way you could safely use usingstatements in your
header files. So AVOID it (As you did mention by yourself it is not very
kind to force users of your code to use namespaces they did not declare
themselves)!  Just try to be a somewhat less lazier :o).
However there are neat ways using those in your member implementations.
Personally I'd like to use internal header files for that purpose.
Including an 'in-between-headerfile' from your source code which
includes the actual classdefinition headerfile. My code organization
then looks as follows:

// member1.cc
#include "classa.ih"   // include internal header, note the "i"

void Member1()
{
}

// classa.ih
#include "classa.h"   // include actual definition header

/* Includes, namespacedeclarations, etc. for your sourcefiles here*/
using namespace blabla;

// classa.h
#ifndef _CLASSA_H_
#define _CLASSA_H_

class A
{
    ...
    void Member1();
};

#endif

This approach however has one big disadvantage. In IDE's such as Dev-CPP
you have to include those files in the linking process manually since
Dev-CPP doesn't recognize the ".ih" (or whatever you'd like to use for
internal headers) extension.

Regards,
    Hielke

Re: [Dev-C++] Using Namespaces

[Siva C. <siv...@ya...>]

hello,

Thanks a lot to Hielke. ( how do you pronounce it? :)
)
I prefer that Dev-C++ does all my project file
management. So I guess I should try to be less lazier.
Your way of using "internal headers" is cool though.

[Dev-C++] Unable to compile

[nornagon <nor...@gm...>]

I recently downloaded Dev-Cpp 5. The only things I've fiddled with are
lib and include paths, for using SDL and OpenGL.

When I've edited a project a bit, the compile buttons all grey out. What gives?

Thanks in advance.

Re: [Dev-C++] Part of toolbar disappears?

[Scott S. <age...@co...>]

I know the config files are kept in the Application Data folder of 
Windows. Do a search for devcpp.ini. However, I do not know your other 
problems.

[Dev-C++] Using Namespaces

[Siva C. <siv...@ya...>]

hello all,

I have a question on using namespaces. Say I want to
build a class ClassA and put it in a namespace abc.
Then I would declare the class in a header file,
header1.h, like:

#ifndef __HEADER1_H__
#define __HEADER1_H__

namespace abc
{ // Start of namespace brace.

class ClassA
{
...
};

} // End of namespace brace.

#endif // __HEADER1_H__

Now I would like to include this header file in
another header file, header2.h. Here again I want to
declare a class ClassB under the same namespace abc.
This ClassB is inherited from ClassA. So to avoid
writing abc::ClassA everywhere I just say:

using namespace abc;

at the begining of the file. My file would be like:

#ifndef __HEADER2_H__
#define __HEADER2_H__

#include "header1.h"

using namespace abc;

namespace abc
{ // Start of namespace brace.

class ClassB : public ClassA
{
...
};

} // End of namespace brace.

#endif // __HEADER2_H__

My question is here: By explicitly putting a statement
like

using namespace abc;

I am including such a statement in all my code which
use this header file header2.h. Is there a way to
avoid such a thing from happening without losing the
functionality I want it to be there for? Or is it that
I am not using it in the right manner?

Thanks a lot for having enough patience to read this
long,

Siva Chandra.
