<DIV><FONT size=2>i just downloaded one of the versions of your compiler (dev - C++ 5 beta 8 4.9.8.0)&nbsp;and i went to start writing a program and it is saying that it cant compile my prorgram. so i was wondering if there was any information that you could email me back, with telling me how i can get it to compile, or is it just the compiler software that is causing this problem.

Re: [Dev-C++] Allocation problem

[Matthews <dem...@uw...>]

I would do that, but currently my email is accessible only through a
computer with no working disk drive/cd drive, etc.  My coding is on another
computer, therefore you see the problem :D  This should be fixed soon,
though, as I'm going to be getting a new computer within the next few days.

[Dev-C++] Problem writing and reading some bytes to and from a file

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

Dear friends,

I wrote the program bellow. It opens a file, records 1 to 5 some times into
a file and close it. Then it opens the same file again, reads its contents
and close it.

First, I defined count from 1 to 5 (hex) getting correct results.

(See attached file: GeraOk.cpp)

Then, I defined count from 9 to d (hex) getting wrong results.

(See attached file: GeraOk.cpp)

I do not understand the reason. Could someone explain it and give a
solution.

Also, I could not get rid of the warning message. Which is the include file
that should be used in order to do not use a deprecated header?

Thanks for your help

Roger

[Ivan S. P. M. <iv...@if...>]

Hi all.
I'm using the last version of dev, and I am having problems with compilat=

one file of a program. The problem is, that when I try to compile all the=
 files,=20
i got the error

fstream: No such file or directory.


but the library is declared correctly, and also works in different files =
in the=20
program.=20

#include "Matrix.h"
#include <fstream>

I've tried to put in the antiquade form, like fstream.h, but doesn't work=

either. What can it be?

Re: [Dev-C++] Allocation problem

Nice to ear.

One thing. Since source code is so very unforgiving about even the
smallest spelling errors it is always a good idea to cut and paste any
source code in the mails.

If you wan't to use MinGW from the command line, then you should 
download the latest MinGW package, and install it. That way gcc will 
find everything, and no need to add -L and -I stuff (except for your own 
libs and includes). It is also a good idea to put the .../gcc/bin 
directory to your PATH, that way you can use gcc from anywhere.

The usage is as follows (roughly):
gcc -Wall -c -o source1.o source1.cpp
gcc -Wall -c -o source2.o source2.cpp
...
gcc -o program.exe source1.o source2.o ...

You may replace gcc with g++ for c++ code. You can ask me about usage 
from command line, as I have used it a lot, and I still use it a lot 
nowadays.

Alan, if you could post the errors you get, that would help the most.

 Hi,  I'm testing Dev-Cpp and GCC compliler, and I'd like to use GCC (g++)
for command-line compiling in WinNT,  but I've got troubles and I don't know
why... I've checked the MingGW site and the compiler optiosn that I'm using

[Dev-C++] Problem writing and reading some bytes to and from a file

[<rog...@em...>]

Dear friends,

I wrote the program bellow. It opens a file, records 1 to 5 some times into
a file and close it. Then it opens the same file again, reads its contents
and close it.


First, I defined count from 1 to 5 (hex) getting correct results.

(See attached file: GeraOk.cpp)

Then, I defined count from 9 to d (hex) getting wrong results.

(See attached file: GeraOk.cpp)

I do not understand the reason. Could someone explain it and give a
solution.

Also, I could not get rid of the warning message. Which is the include file
that should be used in order to do not use a deprecated header?

Thanks for your help

Or perhaps the better solution is:

typedef typename GenericIterator<T>  BasicIterator;

(After all, GenericIterator<> may be a struct. Then for human-
beeings, and not for compilers, the latter is more intuitive.)

Re: [Dev-C++] IF

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

The enum has nothing to do with it.
  if ('u') ...
is the same as
  if ('u' != 0) ...
so the expression will be
  if (letter2 != 'u' || 1 || 1 || 1 || 1) ...
which reduces to
  if (1) ...
which is obviously always true.

Re: [Dev-C++] IF

[Nathan S. <liv...@ho...>]

I'm not sure, but I think this depends on the type of 'letter2' in the =
if statement. Your example code showed: value letter
I don't know if you meant letter2 there, but if so.. you are using an =
enum in your conditional, so this code would be working as expected.

Someone more learned would know more about this.

  How do i tell the compiler i want charactors, not enum values?

RE: [Dev-C++] IF [faked-from][sls]

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

Almost correct. If I understand the original goal, I'd recommend:

if (letter2 != 'u' && letter2 != 'v'
&& letter2 != 's' && letter2 != 't'
&& letter2 != 'a') {
    cout << "Only u,v,s,t,a are allowed" << endl;
    exit();
}

Using || isn't so good since an expression:
  if (var != value1 || var != value2)
will degenerate to the constant expression:
  if (1)
when value1 != value2.

Note that
  if (letter2 != 'u' && letter2 != 'v' && ...)
can be rewritten as
  if (!(letter2 == 'u' || letter2 == 'v' || letter2 == ...))
which is a simple rewrite of a logical expression.
Whenver changing between a && expression and a || expression - either
way is done by:
1: Inverting total result:
   if (xxx) interchanged with  if (!(xxx))
2: Inverting every sub-statement in the expression
   == interchanged with !=
   <  interchanged with >=
   etc.

About the original mail:
  if (letter2 != u' || 'v' || 's' || 't' || 'a')
is the same as:
  if (letter2 != 'u' || 'v' != 0 || 's' != 0 || 't' != 0 || 'a' != 0)
which is a constant expression that is always true:
  if (1)
since any character except '\0' are different from 0.

Re: [Dev-C++] Shift operators portability

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

The read_int() and write_int() functions are the standard way of writing
portable files or data streams etc. Since the file is normalized, it
doesn't matter what machine created it. Obviously, such a file should be
binary so it doesn't contain any newline translations.

One other method often used, is to use htonl(), htons(), ntohl(), ntohs()
to convert between host and network byte order.
In this case, the network byte order is most significant byte first
(lowest address) and it is then possible to write the result of a htons()
or htonl() and write directly:

uint32_t n =3D htonl(my_long);
write(&n,1,sizeof(uint32_t),f);

RE: [Dev-C++] IF [faked-from][sls]

[Geoff B. <Geo...@Vc...>]

You have to declare each side of the '||' as a seperate check.
 
ie:
 
if ((letter2 != 'u') || (letter2 != 'v') || (letter2 != 's') || (letter2 !=
't') || (letter2 != 'a')) {
  cout<<"An error has occured, check you typed in only u, v, s, t or
a."<<endl;
  exit();
  }
 
I do not know for sure if the brackets inside the '||' are required but this
should fix your problem

Re: [Dev-C++] Shift operators portability

[<or...@vp...>]

Hi!

As I see a lot of things are told about this shifting stuff, so I think 
I might also add something.
Bit shifting/or-ing/and-ing and so on, are VERY VERY useful things. 
There might be times, when you need to use all 8 bits of a byte. For 
example, when you have a big-big table (2D), and all you want to know, 
whether one cell is alive or not - 1 byte to store each cell is too much 
waste. Use 1 byte to store 8 cells, and use bit-masking to get the bits. 
But this is only one example, there are hundreds.

And I also want to add something for the endiannes-stuff. Lets consider, 
that you wan't to save a 4 byte integer in binary form into a file 
(binary - save the int in 4 bytes to a file). You will probably begin 
pondering about endianness, and write specific loading code for big- and 
little-endian machines. However, there is a tricky solution to evade the 
endiannes problem, and saving an integer in binary form and loading it 
back will work on both big and little endian machines with the exact 
same code. Here it is (let's consider, that int is 4 bytes, but you may 
rewrite it to uint32_t to be sure):

void write_int(FILE *outfile, int i)
{
   putc( i&0x000000ff,outfile);      /* Write the last byte */
   putc((i&0x0000ff00)>>8,outfile);  /* etc. */
   putc((i&0x00ff0000)>>16,outfile);
   putc((i&0xff000000)>>24,outfile);
}

int read_int(FILE *infile)
{
   int i=0;

   i |= ( (int)getc(infile));      /* Read the last byte: 0x000000xx */
   i |= (((int)getc(infile))<<8);  /* Next: 0x000000xx<<8 = 0x0000xx00 */
   i |= (((int)getc(infile))<<16); /* etc. */
   i |= (((int)getc(infile))<<24);
   return i;
}

The code above doesn't use any explicit conversion from int to char*, 
which is - lets say it - ugly. It works, because bit-shifting is 
"endian-free" i.e. it doesn't depend on endiannes. It works on both 
types of machines. As you can see, it uses the so-blessed shifting and 
bit-masking operators to ahcieve this goal.

I hope I could add something useful.

Re: [Dev-C++] Shift operators portability

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

The program picks up the first byte of the integer - as stored in memory.
If it is 1, it's the side where the "little" part of the integer is
stored. If it is 0, it's the side where the "large" part is stored.

Intel, AMD store low byte of integer first, so it is expected that at the
first byte of the address of the integer, the value 1 should be stored.
The other three bytes of the integer will all be zero.
