It should be \\ . But if i recall correctly MINGW follows the UNIX style
which is / .

I did not understand the question but "The C Programming Language" 2nd
edition by Brian Kernighan - Dennis Ritchie is a great book.

Uhm ... let me see if I understand the situation.

Say that I have a console application, named "cp.exe", which will duplicate 
a file (the source code, "cp.c", is attached).

Now I have:
- the binary file in "c:\rch" (thus full path name of the file is 
"c:\rch\cp.exe")
- the data file I wish to duplicate is "c:\rch\data.txt"

According to you, if I open a Dos box (I'm running Win98SE), switch my 
current position such that the prompt says I'm in "c:\rch", and issue the 
command:

cp data.txt a_copy.txt

I should expect some error to occur.

Well ... I did exactly what I described and no error occurred. :)

Now lets change situation.

I wish to run the console application "cp.exe" from within the Dev-C++ IDE 
(i.e. I click the "run" button). It is possible, but I do not recommend it; 
or better: I have only limited knowledge, so do not know hot to ensure that 
Dev-C++ will run the application from the directory I want. IMHO, console 
applications (by the way the sole kind of programs I am able to work out), 
must be used from within a Dos console.

I run Win98SE so can't say how things go on Win2000. However I think that 
the path you have written, that is: "C:\Dev-C++\Dir1\Dir2\filename", is not 
a valid one. Because of Dos using backslash ('\\') as directory separator, 
your string appears as: "C:Dev-C++Dir1Dir2filename" (which is, highly 
likely, a non existing file of the current directory on the unit "C"). The 
right way to write your path is: "C:\\Dev-C++\\Dir1\\Dir2\\filename", 
because this is the way to insert a backslash within a C string.


>There must be a better book for re-learning C than "A Book on C" or K&R!

This is something where I'm of little help, I've learned the few things I 
know about C, from the well known K&R - 2nd edition. I remember the preface 
telling that the book is not for beginners, but this should not be your 
case since you are "re-learning".

[Dev-C++] More: Reading file with getc(fp)

[rchavez <rc...@so...>]

Hi,

Thanks for the replies.  I added a check for NULL file pointer and found
that indeed it is NULL.  That explains why the same code works in unix but
not in Dev-C++.  (In my defense I took the example directly from a book.) 

So 2 new questions:

1.  If the source file & the target file to be read are in the same
directory I am using in Dev-C++, shouldn't

   fopen("filename","r") find the file?    It doesn't seem to.

2.  Is

   fopen("C:\Dev-C++\Dir1\Dir2\filename","r") a valid explict path syntax in

Windows 2000  ?        (assuming Dir1 & Dir2 already exist)

There must be a better book for re-learning C than "A Book on C" or K&R!

Regards,
Rob.

i posted a message to the forums yesterday about
runtime errors i was getting when i would execute a

violations and every so often Dev-C++ would crash. 

it seems to be the projects i had troubles with were
located deep in the file system, so i created some
bogus projects to see if the problem was related to
the pathname. it seems that when the folder name is
verylarge or the path to the project is long Dev has a

BTW, when it crashed it says that it is generating an

I have attempted to run you code and the same thing happened to me, I think 
the reason is: when the file named "word.h" does not exist, fp is assigned 
a NULL value, so your code attempts to read something using a NULL pointer, 
as a result, a run time error occurs.


>There are no warnings at compile time.

I shall not agree, in fact I tried to compile your code (using Dev-C++ 4.0 
with MinGW 2.95) after setting these additional options:
-Wall -Wnested-externs -Wredundant-decls

Here is what I get in the "Compiler" panel:

4 c:\mail\rob\orig.c warning: return-type defaults to `int'
7 c:\mail\rob\orig.c warning: nested extern declaration of `fopen'
7 c:\mail\rob\orig.c warning: redundant redeclaration of `fopen' in same scope
179 c:\progra~2\dev-c_~1\include\stdio.h warning: previous declaration of 
`fopen'
13 c:\mail\rob\orig.c warning: implicit declaration of function `system'
C:\mail\rob\orig.c compiled successfully

As you can see these are only warnings, so code is generated at your own 
risk! :)
Anyway, at compile time one can't catch run time errors.

I do not know what the function "getch()" does, one thing I'm sure of, is 
that it is  not ANSI C 89.

>1. How do I make it work with Dev-C++ ?

Try the code I wrote below, it works on my machine (Win98SE, Dev-C++ 4.0, 
MinGW 2.95).

Note, if you are using my same version of Dev-C++, make sure that:
"Options"->"Compiler Options"->"Linker"->"compile for Win32 (no console)"
is unset, otherwise you will see nothing displayed on the screen.


>2. There was lots of talk on getch() and getchar() in the archives but
>nothing on getc().  Is getc() no longer ANSI C ?

Don't know what ANSI C99 says, however, since "getc" is in C89, I suppose 
it is still supported

>3. getch() swallows the cntrl-Z so I can't properly terminate using std

As I said above, getch() is not a standard function.

>4.  Why is EOF cntrl-Z instead of cntrl-D in Dev-C?

This is not related to Dev, it has to do with the differences between Dos 
and Unix.
Since Dos came after Unix, I see no reason why to assume different 
conventions (another one I don't understand is the backslash and the slash 
issue).

You need to add no special line of code if you run console applications 
from the ... console! :)

Also remember that using function "PAUSE" makes program not portable to 
Unix (where there is no command named "PAUSE").

/* file test.c */
#include <stdio.h>
#include <errno.h>

#define FILENAME "words.h" /* name of file to be read */

int
main()
{

   FILE* fp = fopen(FILENAME,"r"); /* the file */

   if (fp == NULL)     /* unable to open file */
     perror(FILENAME); /* notify user */
   else /* ok, file is open */
     {
       int c; /* the character read from the file */

       while ((c = getc(fp)) != EOF)     /* found a character */
         printf("\ngot a char %c", c);   /* display the character */
     }

   return 0;

I haven't used libtool, but mabey you could try compiling your lib as a dll, using dev-c++ (new Project -> dll)? I an't think of a reason why it would make a difference, but who knows, it might work?

Re: [Dev-C++] A basic q...

[Luigi S. <gi...@li...>]

Hello Daniel,

A makefile is a set of instructions (a program if you wish) that will be 
interpreted by a program generally known as "make".

"make" is a general tool, not strictly related to programming languages, 
but undoubtedly one is likely to run into it when dealing with "compiled" 
programming languages.

Here is what I mean.

Consider the classic "BASIC" programming language (hope you know a little 
about it), a program written with such language is a set of instructions 
which a BASIC interpreter reads and executes, one at a time, each time you 
run the program. There is no executable file and to run a program you 
always need: the source code and the interpreter. Also, if a program has 
syntax errors, you will find out about them, only when the interpreter 
executes the offending line of code; in fact only at that time it will 
realize that the instruction is wrong.

Consider instead a C (or C++) program (I mean here what is known as a 
statically linked program, that is, one which does not use any DLL). You 
write the source code, a compiler will then translate it into an object 
file which a linker will use to make an executable file. Thus the program 
is translated into machine code only once (and not each time you execute 
the program), also to execute the program, you only need the executable 
file (often called the binary file) and nothing else (this of course is not 
true of dynamically linked programs, which also require the right DLLs). 
Since to run a program, you must have compiled already *all* the 
instructions, if there are syntax errors, you will find out about them, at 
compile time, no instruction will be executed if there are syntax errors.

Now here is the reason why one uses "make" with compiled programming languages:
say that one writes some source code and then compiles it, making the 
corresponding executable file, now suppose that he makes some changes to 
the source code, what happens is that the executable file no longer 
corresponds to the source. This never happens with interpreted languages, 
because, as I said, there is no executable file for those languages.

The classic way (don't know how many still use it) to keep a binary up to 
date is to use "make". Roughly, What "make" does is the following:
- read the time stamp of the binary file
- read the time of the corresponding source file
- if the source happens to be "younger" that the binary, this latter is 
out-of-date

When the binary is out of date, the actions needed to update it will be 
performed, by "make".

Things are a bit more complicated when a program is made of code spread 
across different source files, but the basic idea is the same.

At this point you could ask:
- How does "make" know which source file is the one used to compile some 
binary file?
- How does it know which are the actions to update a binary file?

Well, you put these informations in a text file, named "makefile", 
arranging them in some special way (just the syntax understood by "make").

The above is, I hope, the frame of the picture: if you wish to fill it with 
details, you could start by reading the manual of the GNU "make" (I've 
found it on the Dev-C++ resource site).

extern "C" is used for functions defined in a .c file, that is to
interoperate with C stuff e.g. a C library. In your case extern "C" is
not needed since you programmed in C++ (even in C-style C++).

RE: [Dev-C++] Reading file with getc(fp)

[<igo...@po...>]

Hi,

For reading files try using fgetc instead of getc
and your program should work OK.

Subject: [Dev-C++] Reading file with getc(fp)


Hi,

I am trying to read a text file in a C program.  This code runs fine on the
unix C environments I can access but gives a fatal error that removes the
console window in Dev-C++ environment.  There are no warnings at compile
time.  It is definitely the getc() that causes the trouble because the
program
works in Dev-C++ when I use getch() and take input from standard input.

   Four questions:

1. How do I make it work with Dev-C++ ?

2. There was lots of talk on getch() and getchar() in the archives but
nothing on getc().  Is getc() no longer ANSI C ?

3. getch() swallows the cntrl-Z so I can't properly terminate using std
input.  How do I overcome this when I want to use getch()?

4.  Why is EOF cntrl-Z instead of cntrl-D in Dev-C?  

Your help will be greatly appreciated and you people are wonderful to give
so much help to the clueless like me on this list!

Rob.

-----------------  my code --------------------------

#include <stdio.h>

main()
{

int c;
FILE *fopen(), *fp;

fp = fopen("words.h","r");
while ( (c = getc(fp)) != EOF )
  printf("\ngot a char %c",c);

  system("PAUSE");                /** added this for Dev-C++ **/
      return 0;
}

Re: [Dev-C++] newbie problem

I got it to work by moving the declaration above the implementation

all you have to do is move

[Dev-C++] newbie problem

[Kenneth A. <dig...@ho...>]

i tried to make a program that uses both c and c++ commands.  well, i'm new 
to this so it didn't work.  the error that i got was "call of overloaded 
'CeFunction()' is ambiguous".  here's my code:

#include <stdio.h>
#include <iostream.h>

int CeFunction()
{
     printf("In C mode.\n");
     return 0;
}

extern "C"
{
       int CeFunction();
}

int main()
{
  cout << "In C++ mode.\n";
  CeFunction();
  cout << "Back in C++ mode.\n";
  return 0;
}

if someone could explain what i did wrong here i would be very thankful.  go 
easy on me please, i'm a newb. :)
