[Dev-C++] dll or no dll

[Neszt T. <ne...@ss...>]

Hello!

Could someone explain me why need any dll for my program?

What I do: 
- #include <aaa.h>
- link: -laaa (there is libaaa.a in the dev-c++ lib directory) 

Everything is ok. The project is compiled succesfully. But after starting,
the program needs aaa.dll

Am I right, that the header and/or cpp (aaa.h, aaa.cpp) defines all the
callable functions, and the real functions is in the libaaa.a ??

If yes, why need the dll file? (for example if aaa=glut32, or aaa=fmod or ...) 

I simply don't want many dlls beside my program.

I check all the regarding programs (Exebundle, Fusion, PEBundle, ...), but
there are many problem with these.

My aim is that all the functions what I need is should be in the builded
exe file.

So is there a soluton? Dev-c++ settings by any chance?


Regards,

Neszt Tibor

Yes, it is possible to do with char*

char* alloc_bits(unsigned bits) {
    char *bits;
    unsigned size;
    size =3D (bits+7)/8;
    bits =3D malloc(size);
    if (bits) memset(bits,0,size);

void set_bit(char* bits,unsigned bit) {
    array[bit/8] |=3D 1 << (bit&3);

char *mybits;

mybits =3D alloc_bits(1000);
if (mybits) set_bit(mybits,117);

[David M. <ci...@ya...>]

Do you know how many bits you will need at compile time?

If you then use a bitset. It is part of the STL.

If you don't then you can use vector<bool> and hope your
compiler vendor
optimized it for space.

Hope this helps

[Dev-C++] DLL vs Lib linking

[Michael S. <mic...@nu...>]

Hi,
=20
I=B4ve seen libraries (for example wxWindows) that rely on other =
libraries
(e.g. user32.lib), means that they have unresolved symbols in it. When I
want to link against wxWindows, I=B4ve to link with user32, too.
Now, when I want to build a .dll instead of a .lib with the same code, =
the
linker tells me of many unresolved symbols (which are there), as opposed =
to
a .lib, where the linker isn=B4t even invoked (under MSVC .NET).
=20
Am I understanding something wrong here, or how can I create a .dll =
which
relies on other libraries?
=20
Thanks for your help

the standard include files can now be generated
* Improved WebUpdate module
* Many bug fixes

You can download it from:

hi dev-cpp-users,

i want to allocate a string and then perform operations on its bits,

but all the time such operation will give me an error on types..

Hi People,

thanks for your answers. The fault was my own stupidy, since the
input variable was int and so it could not get the float part
because it didn't had one :)

Re: [Dev-C++] Casting Problem

[Michael D. S. <for...@hi...>]

I know one thing, It can be done.

I did it, late last night as an error. It was driving me nuts until I found 
it. Unfortunately, it was late, and I cannot duplicate the results now. I 
think it had something to do with some parentheses being -- not quite right 
:) But I'm not sure.

It's just the one liner that's a trick. Certainly a little longer version 
will work easily.

int wholenumber;
double number;
double decimal;

wholenumber = int number;
decimal = number - wholenumber;

That's untested, and I'm still occasionally mixing in some PERL, so... 
caveat emptor.

That is, because you cannot just save every bit of an object (unless you 
are able to recreate the same runtime state on load as it was on save, but 
this is not a concept unless you are the os). The std::string will break 
your neck, because it uses dynamic allocated memory and pointers to it. 
When you save your file, you will save only a pointer value to a memory 
address which is no more valid when loading. You will have to create a 
write/read member function for your class, which uses the stream to save 
and load itself.

RE: [Dev-C++] Which include file to choose?

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

Everything in the new headers (the standard C++ headers) is defined in a
namespace called "std" (stands for "standard"). You can access
variables/functions/classes in the std namespace by using the scope
operator ("std::cout" for example), by importing them into the current
namespace by a "using" directive ("using std::cout;" for example), or by
importing the entire namespace into the current namespace ("using
namespace std;"). For cout/cin/cerr/clog etc you should use <iostream>.
Here's a small example:

#include <iostream>
using namespace std;

int main()
{
    cout << "Goodbye cruel world." << endl;
    return 0;
}


Hope this was of any use to you.

Goodnight,


Paul

When I hear you talk about library declared in the scope of the file...

Might you talk about an include file?

A library isn't something a c or cpp file bothers with, but a binary file
used by the linker to add extra functionality in your program.
