Perhaps you should learn how to use a mailing list first?  You should 
probably start a new thread, instead of hijacking someone else's.  In 
common speak, what you've done is rude.

Also try using Google.  A simple search for "pthreads howto" turned up 
this excellent resource:

http://www.yolinux.com/TUTORIALS/LinuxTutorialPosixThreads.html

I would also glean that you need further training in how to use a 
keyboard effectively, as I've never seen the "cppluss" language before. 
  I assume you're really talking about C++, which is a very popular 
language.  If this new "cppluss" language is somehow superior to C++ in 
some way, please let me know, since I'd be very interested to see it!

Hi  All;
    I would like to compile and run a multithreaded cppluss program
using pthread library how is this done.

I've been thinking that its possible the library needs to be built using
my crosstool, does this sound reasonable?  have been attempting to get
gsl built with my crosstool in cygwin. but I am having problems with
that as well.

You don't specify what library to use.

C and C++ do not automagically try all libraries, just because you add
them in your search path. -L <directory> just tells the linker where to
look for a library that you have explicitly included in the linking.
There
are a few exceptions, which allows the standard RTL to be linked without
you specifying the name.

If you somewhere in all the library directories you specified has a file
named libgsl.a, then you should have had a -lgsl to tell the linker to
make use of this gsl library.

You haven't specified your environment.

Linux? Cygwin? Other?

If Cygwin, have you installed the ioperm.sys driver?

If Linux, have you read the man pages, saying typically:
"You compile with -O or -O2 or similar. The functions are
defined as inline macros, and will not  be  substituted
in without optimization enabled, causing unresolved
references at link time."

Always make sure that you supply _ample_ information when asking
questions, since the people who you want to answer your question only have
the information in your mail. We can't guess what extra information you
have left out.

I'm trying to use the function outb, already received permission to use the
function ioperm the parallel port, but the task is not writing in the
output. Any ideas on this?

please see this:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <asm/io.h>
#include <unistd.h>

#define LPT1 0x378

int libera_porta(){
        if(ioperm(LPT1,3,1)==1)//libera acesso para os endereços
0x378,0x379,0x37A
        return(1);
        else
        return(0);
    }

fecha_porta(){
        ioperm(LPT1,3,0);
    }

main(){
    if(libera_porta() == 1)
        printf("\nPorta liberada com sucesso\n");

    else
        printf("\nPorta nao liberada\n");

    //outb(255,LPT1);

    fecha_porta();

}


I was execute on root, but never get permission to use the lpt, and when
outb is not reviewed I recive this error: (.text+0x101): undefined reference
to '__outb'.

I think you are in need of a good C or C++ book.

The interface should be in a header file (*.h or *.hpp), and the compiler
will make use of this header file because you #include "my_header.h".

When specifying the file name with "" instead of <>, the compiler will
first look for the file in your project directory, i.e. the same place as
you have your *.cpp file(s).

If you have multiple *.cpp files, then you just make sure that the project
contains a reference to each and every *.cpp file you write. That will
take care of the implementation.

i separated the interface of a class (as a header file) from its implemetation. how do i tell the compiler to look for the header file

Oops, yes you are correct - I missed that one.

It is so common that people only includes their header files and specify
the correct library directories that I more or less take for granted that
the actual -lxx parameter is missing :)

I am trying to write a small OS kernel, and i need binary output for that.

So, why don't you start your request by telling exactly what you need a
your binary file for?

Are you trying to write a BIOS for your computer?

You can not pass an arbitrary plane of a three-dimensional array.

You can pass a reference to the full array, together with a parameter that
specify if you mean an X plane, an Y plane or an Z plane, and an index
that specifies which plane.

Then the function will itself have to locate the entries in that plane. To
do that, the function must also know the size of your cube in all three
dimensios.

You may have to specify even more parameters if it is important that the
function processes this plane in the correct order, i.e. you may have to
specify u and v vectors, where the u vector may specify that the function
should walk the cube from high z to low z, and the v vector may specify
that the function should walk the cube from low y to high y.

You don't specify what library to use.

C and C++ do not automagically try all libraries, just because you add
them in your search path. -L <directory> just tells the linker where to
look for a library that you have explicitly included in the linking. There
are a few exceptions, which allows the standard RTL to be linked without
you specifying the name.

If you somewhere in all the library directories you specified has a file
named libgsl.a, then you should have had a -lgsl to tell the linker to
make use of this gsl library.

Why do you assume that it should work?

The BIOS operations where defined for 16-bit MS-Dos. Dev-C++ generates
code for running in protected-mode.

Switch to a free edition of an old Borland C compiler if you want to write
16-bit applications that makes use of BIOS functions.

Or take a look at DJGPP, a gcc port with a DOS-extender, that will
simulate compatibility with 16-bit interfaces.

There is no limitation on double pointers. This is a limitation in your
understanding of the const keyword, and what it binds to.

You can have a const pointer, i.e. a pointer that may not be changed to
point at a different double.

You can have a pointer to a const value, i.e. you may not assign a new
double value using the pointer.

And you can have a const pointer to a const double, in which case neither
the value of the pointer, or the value that the pointer points to may be
changed.

When you add a second indirection (pointer to pointer to double) you just
get one more position where you can add your const, i.e. if the first
pointer level allows you to change the the value of the second-level
pointer.

You should get the C++ standard, and look at the rules regarding const,
and regarding pointer declarations.

Hello everybody. I am trying to use MinGW to make a flat binary image, 
but am unsure how to do it.  I tried to compile using the following 
commands:

gcc -c program.c
ld program.o -o program.bin --oformat=binary --Ttext=0x0

this told me that I could not perform PE operations on non-PE file 
program.bin. I also tried this:

gcc -c program.c
ld -o test.bin -Ttext 0x0 -e _main test.o

This gave me the error:
Undefined reference to _alloca
Undefined reference to __main

How do i specify the command line options to make the binary image? 
Also, if i cant use gcc, how can i use g++ to make the binary image?

I am running Dev-Cpp 4.9.9.2
The following generates an error at the function call:
invalid conversion from 'double**" to 'const double**'

The program runs if the 'const double**' is changed to 'double**' in the function definition.
Conversions such as 'double *' to 'const double*' in the function pose no problems.

This limitation on double pointers surprises me. What should I be doing differently?

Thanks



void Multiply(const

Ok, so i have a dilemma. I want to link assembler code to my C program 
that will print a line pointed to by a char *. the function is defined 
in my program as: extern void print_string (char *); and the assembly 
code is:

_print_string proc near

    PUSH BP

    MOV BP,SP

    MOV AH,09h
    MOV DX,OFFSET [BP+4]
    INT 21h

    POP BP

    RETN

_print_string endp

can anyone tell me why this is failing? I am trying to get the address 
off of the stack and then use it to access the string. What is the 
appropriate way to do this?

Does anybody here use scon to build files and use eclipse to do debug?

any idea or suggestion from scon are welcome.

thank you

the reason that this confuses me is that I have the libraries stored in: C:\cygwin\lib  and the includes for gsl in: C:\cygwin\usr\include.  If anybody can help me out I will be eternally grateful.

use this trick 
put the 3-d array into a structure like this

typedef struct ARRAY3d{

  int ***Data;

};

now it can be easy to pass between functions :)

Hi, I am working on a C source file that uses a 3-dimensional array
declared as pointer-to a pointer-to a pointer. Could anybody tell me
as to how I can pass a particular plane of this 3-d array to a
function.
Also, if anybody can provide/suggest C code for calculating FFT (fast
fourier transform) and its inverse of a 2-dimensional complex array.

Hello. I was wondering if anyone could tell me how to output a flat 
binary image from c source in dev-cpp.
