There IS a command line utility which creates archives, or libraries and 
it comes with Dev-C++ (MinGW). It is called "ar" (archiver). Actually, 
Dev-C++ uses this. It can create archives from object files. You first 
need to compile all sources to object files.
Type "ar --help" to get a list of comand line options. The most common 
options are "ar cru <libxxx.a> *.o"
In "*.o" * is a wildcard, so ar will get all .o object files and create 
the archive.

A quick'n'dirty way to create an archive (library) of all sources (.cpp 
and .c) in the current dir, type these 2 commands:

g++ -c *.cpp *.c        - (compile all .cpp and .c files to objects)
ar cru libxxx.a *.o     - (create the archive)

Re: [Dev-C++] .cpp to .lib or .a

[<sol...@ya...>]

For what I know about it the .a format is the same than the .lib for 
MSVisual C++ (coff), so you shall only need a rename of the .a file to 
.lib; if you want use it for Borland, which uses OMF format, you need 
run coff2omf.exe, which is in the binary folder of Borland.
If that doesn't work, then it seems you'll need use reimp, if you need 
it (I don't think so), email me and I'll send it to you, it's small and 
it seems not very easy to find.

Hope it works.

I don't think that's it - see he wrote #include <iostream.h> not <iostream> 
therefore the namespace issue doesn;t apply.

[Dev-C++] carriage returns

[<tel...@ya...>]

Greetings all.

Question in relation to an assignment.

i need to take in input one character at a time, each character to be followed by a 'carriage
return'.

i've looked around on the net, but i seem to get differen definitions.

Some sources say it's the same as 'newline' others say it resets the relevant cursor to the left
of the CURRENT line, and not the newline.

It seems the current line definition holds when the '\r' char is used as output, but is this what
the 'enter' key performs?

can anyone help clarify this?

Thanks

Re: [Dev-C++] Static in member function

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

If I do

// Example 1
const char* myfunc(int i) {
    static char my_buf[10];

    sprintf(my_buf,"%d",i);
    return my_buf;
}

the my_buf variable is actually a global variable but without a global
name. It is similar to

// Example 2
static char my_buf[10];

const char* myfunc(int i) {
    sprintf(my_buf,"%d",i);
    return my_buf;
}

with the exception that in the first case, noone in the same or other
source files may access my_buf, while in the second case everyone in the
same source file may access the my_buf[] variable, but the linker will not
export the variable name so code in other files will not be able to access
it.

If I then finally do:

// Example 3
char my_buf[10];

const char* myfunc(int i) {
    sprintf(my_buf,"%d",i);
    return my_buf;
}

then I'm all the way to a normal global variable, accessible by anyone.
In C++, there is one more alternative for the static keyword:

// Example 4
class MyClass {
    protected:
        static char my_buf[10];
    public:
        const char *myfunc(int i);
};

char MyClass::my_buf[10];

const char* MyClass::myfunc(int i) {
    sprintf(my_buf,"%d",i);
    return my_buf;
}

where everyone inherriting from MyClass may access  MyClass::my_buf[]
since it is in the 'protected' section of the class definition, but where
all objects instanced from MyClass or a descendant of MyClass will share
the same variable. This is because MyClass::my_buf[] is a global variable
with a compile-time access restriction - in this case 'protected'.

In short, whenever the static keyword is used, there will be only one
instance of the variable, but depending on where the static keyword is
used, the access scope of the variable will be either a single file, a
sungle function or a single class.

Re: [Dev-C++] Allocation problem

When you allocate buffers for strings, you must allocate room for
strlen(str)+1
characters, or the termination character '\0' will not fit.

[Dev-C++] Probs with opengl in Dev c++ 4.9.8.1 (Latest version)

[Prathmesh M. <P.M...@mu...>]

Hi all,
   I have recently downloaded the latest version of Dev C++ 4.9.8.1. =
Now, I m trying to configure opengl with it, but I m facing problems and =
cant compile my programs. Some sites advise to paste the foll. line =
"-lopengl32 -lglu32 -lglut32" in the box "Further object files or linker =
options", which is supposed to be found in Project --> Project Options =
menu. But I cant find that box "Further object files or linker options" =
in the latest version. So could anybody plz suggest me an alternate way =
of setting up opengl properly in this new version? Many thanks to all in =
advance for your time and effort.

Re: [Dev-C++] tutorial for win32 programming...

[<gen...@ya...>]

here are some links that have been useful to me:
 
http://www.winprog.org
http://www.relisoft.com/win32
http://www.catch22.org.uk/tuts/
http://www.foosyerdoos.fsnet.co.uk
 
also, the BlackSun Research Facility (http://bsrf.box.sk) has some tutorials on Win32.
 
as far as books are concerned, you can get "Programming Windows" by Charles Petzold, and "Programming Applications for Microsot Windows" by Jeffery Richter.

Re: [Dev-C++] Static in member function

[<gen...@ya...>]

Per Westmark's right, they would share the same variable, tho i'm not sure why... any answers would be appreciated... thanks

Re: [Dev-C++] Static in member function

[<gen...@ya...>]

Hello,
just in case no person has answered this (though i believe someone has), the answer is each object will have its own instance of the variable. in this case, the variable is simply a regular static variable in a function, and all the normal rules for static variable declared in a function apply.

If a static variable is declared inside a member function of a class, what 
would happen?
That is, would all instances of the class use the same value, or would each 
instance have its own copy of the variable?


The function is defined something like this:

int Array::unshift() // unshift
{
static int *active=first;

// the function is supposed to return the i:th element on the i:th call

}


Thanks for any help

Re: [Dev-C++] Needed Header Files

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

They DO need the headers. Use the -Wall flag to see what happens, if you 
don't use the header. It will tell you something like:

prog.c:11: warning: implicit declaration of function `printf'

That is, printf is implicitly declared by the call to it. Now you 
probably wonder: "OK, that's fine, but shouldn't there be some linker 
error?" The question is right, there should be. But as far as I know, 
gcc (more accurately: mingw, dunno about other OSes) automatically links 
with a few system libs. Like "g++" is actually "gcc ... -lstdc++", so 
g++ automatically links with -lstdc++. Like this, gcc (mingw) links with 
-lm for example, and some other libs.

But anyhow, you should ALWAYS include the respective header file for the 
function to make portable code. Use -Wall to see if you missed something.

[Dev-C++] Allocation problem

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

I'm working on a program to generate makefiles for me, and I currently have
it set up to read different sections of a file to generate the options.
One section is %input, which has a list of filenames to include, eg.

prj.txt

%input
main.c
vid.c
gui.c

I read these into a struct organized like so:

struct prj_info
{
  ...
  char **input;
  ...
}

And I allocate space based on how many files there are (an array of
strings, basically)

My problem is that I get errors when running the following C code:

if(!strncmp("%include",t,strlen(t)-1))
{
  count = 0;
  skip_line(buf);
  getword(buf,t);
  longest_length = strlen(t);
  info.input = (char *)malloc((sizeof(char)*longest_len)*1);
  if(!info.input)
  {
    printf("OH NOS\n");
    return 0;
  }
  //CRASH HERE
  strcpy(info.input[count],t);
  while(*buf!='%')
  {
    while(*buf=='#'||isspace(*buf)) skip_line(buf);
    getword(buf,t);
    if(strlen(t)>longest_length) longest_length = strlen(t);
    count++;
    realloc(info.input,(sizeof(char)*longest_length)*count);
    if(!info.input)
    {
	printf("ERR0RZ\n");
	return 0;
    }
    strcpy(info.input[count],t);
    skip_line(buf);
  }
}

Buf is the dumped contents of a file (like prj.txt), getword() places a
word from buf into t and skip_line() skips to the next line in buf.

The code compiles fine, but crashes at the first strcpy().  Any help would
be appreciated.

Dev-C++ not including header files in the dependency of a source
file, is a long time bug (it even affected the last stable version).

Good luck fixing it.

[Dev-C++] int main & void main

[<and...@su...>]

Dear Users,

   I think I´ve made this question about one year
ago, but I lost the e-mail :-)

   -->What is said in the standartization point
of view to start programing C codes today with
"int main" funcions and no more with "void main"
functions?

Andre

One of these days I will teach myself how to do this :) I have to do my Uni
stuff right now but :( they teach us Java after 3 subjects of C++ for some
reason. Are there principles that can carry over to Win32 programming in C++
from that?
