What do you mean by "DIR structure of TREE_CODE"? It's not really clear ...

Hi,

I was trying to gcc a file and obtain the following error message, do you
know what is happening to the gcc command? Is it true that gcc will engage
cpp command as shown in the error message? Or do you know what is happening
as I am for sure do not know what is happening? Or do I have a bad gcc
installation

Thanks & regards,
chee

Hi!
I'm trying to set up gcc and rhide to learn C and C++.
I have downloaded the recommended files for my system, set them up as per 
the instructions.

My beginning program compiles with out error.

But the Make command in rhide produces the following error:

"Error: c:/djgpp?bin/ld.exe : cannot find -lgcc"

I have spent days reading the online material to no avail.

I need help!

You didn't tell what operating system you use... I see that windows.
Maybe try to use DevC++ it has a gcc compiler in its package, very
nice for beginners... Try it:http://www.bloodshed.net/dev/devcpp.htm

main returns an int, but the void in the parameter list is not

Yeah, I know. The point was just the int return type. Maybe the
wording was not that good at last.

Hi,
I am writing C++ program for displaying a table of tangents given the
lower and upper limits. The program initially rounds off ( e.g if one
enters 29.58 and 30.33, it rounds off it to 29.6 and 30.3), and output the
result in a table form. I have this problem with displaying the table
completely and correctly, it was challenging for me to figure out where
was I going wrong? Can you please help me out with it.

When I entered, 29.58 30.33 it stops at 30.2, for 32 34, it stops at 33.9
but when I entered 84.14 84.44 and 89.44 89.48 it gives me correct table.
I am enlcosing the code that I wrote.

Thanks,

At first, please note that this list is about the usage of or problems with 
GCC, the GNU Compiler Collection. Skimming through your post I haven't found
the word gcc / g++ etc. not a single time. This makes me suspect that your 
problem would've been better addressed somewhere else. 

Anyway, to answer your question:

You need to remember that floating point numbers are inherently imprecise
and that you can't expect that if you add 0.1 to a floating point number
that its value will increase exactly by 0.1 nor that 0.1 itself can be 
exactly represented as a floating point number.

>  //cout<<"\n\t "<<min_Value<<" "<<max_Value;

You can't see a difference here because you've set the precision of cout to 4.

Just issue a "cout << setprecision(50);" right before the (uncommented)
line above and you'll see what I mean.

You probably want to round the min_Value in every iteration, e.g.

  min_Value = floor(min_Value*10 + 1) / 10;

This is not much better, but it avoids that the inaccuracies add
up too much during the loop.

Or, you may compute the numbers of iterations before entering the loop
and use an integer variable to do the counting. Something along the lines of

  for (int i = static_cast<int>((max_Value - min_Value) * 10)); 
       i >= 0; --i) 
    // ...


A few notes about your code:

You're using the old C++ headers. In new code you might want to use
standard headers like 'iostream' instead of the antiquated 'iostream.h', 
'cmath' instead of 'math.h' et cetera.

> void main ()

This *needs* to be "int main(void)".

> for (int j = 1;j<=100;j++)
> {

You might find it easier (or at least shorter) to write 
'cout << string ("-", 100);' instead of the above.

Cheers.

Damn, this should read "cout << string (100, '-');', of course. Sorry.

	GCC can create shared libraries with the -shared commandline
option.  The default is AIX-style shared libraries, but you can use -Wl,-G
to compile the library and -Wl,-brtl during the final link to generate
SVR4-style libraries.

	When compiling and linking C++ code, you should use the "g++"
driver, not the "gcc" driver.

	When compiling and linking pthread code, you should use the
-pthreads commandline option, which implicitly links with -lpthreads.


-p 5000

and

-bmap:/home/pkulka/poc/xerces-c-src_2_5_0//obj/libxerces-c25.0.map

are IBM xlC compiler options.  You need to use the correct GCC commandline
options.

	/usr/lpp/xlC/lib contains libraries for xlC.  xlC C++ ABI is not
compatible with G++ ABI -- you cannot mix C++ object files produced by the
two compilers.

hi,

I need to know few information about GNU AIX cross
compiler

1. I am working on Sun Solaris on Sparc machine.  The Target is a
powerPC with AIX as OS.  I don't have AIX compiler.  Can I use the GNU's
AIX cross compiler to build the executable for the target from Solaris
environment?

2. How can I test it from Solaris..(I mean compiler options for a simple
program? )

3. Is something more than the cross compiler is required to make the
executable run on the target.

Thanks in Advance

There is one other subtle point than can come up 
here, and that is if you are compiling a C++ program,
in general, the command you need to invoke is g++,
not gcc, i.e.

g++ waynesadolt.cpp

or whatever variant you are using for the program.
g++ does some operations behind the scenes to deal with
the program being a c++ program.

Hi,
   I am R.Karthik Narayanan, I am student at UCF. I have been trying to do
programming in lunix using GCC. I find that my C programs work without any
errors. But the problems seems to happend when i do GCC for C++ programs. It
fails to find the file iostream.h. But, there is no error nad the program
compiles. But when i try to execute it using ./name of compiled file, there is
no reponse, the program doesn't run. Can u please guide me as to how solve this
problem.

iostream.h is not part of ISO C++. The name was changed to <iostream>
    (no suffix) during the standarization process which was completed
    in 1998. (Although the iostream.h => iostream change was final
    long before most of the other changes.)

Since you don't know about <iostream>, I'm going to assume you don't
    know about the std namespace. During the standarization process,
    all standard C++ library names, including cout, endl, string, etc,
    were moved into the std namespace. Here is an example:

#include<iostream>
#include<ostream>

using std::cout;
using std::endl;

int main()
{
    cout << "Hello world" << endl;
}

I think there is some confusion. If iostream is required, but not
    found, the program will not compile. You must copy and paste the
    exact error messages you get, and the code that reproduces them
    (or a simplified version thereof). If you don't do that, people
    can only guess at your problem, and are less able to help you.

response i got. I hope i could be of help to you guys sometime, I did
the changes like you guys had told me( esp:- Llewellyn Reese ). See i
made te changes like you told me , but i could not still get any output
from my program. The program compiled without any error, but i simply
couldn't see any out put for it. I am attaching the source of the simple
program , hope u can help me out in figuring out whats wrong.

Thanking you,
Sincerely,

cout is a buffered stream. This means it saves the output in a buffer,
    until a long block of optimal size is obtained. The buffer isn't
    written to output until it is full, or gets flushed. I don't
    believe the standard requires the buffer to flushed when the
    program exits. So if you do not use << flush, or << endl here, you
    may see no output.

[ram]

hi

I have a C progam written for DEC UNIX. I am unable to compile this on
Redhat linux with gcc version gcc-2.96-81 .

I get following errors

itfrecv.c: In function `ack_funct':
itfrecv.c:389: too few arguments to function `send'
itfrecv.c: In function `errlog':
itfrecv.c:422: warning: passing arg 3 of `write' makes integer from pointer
without a cast     

the lines are as below

 389         send(sockfd, buffer, strlen(buffer));
422         write(fd, buffer, index);  

what should I change to make the program compile with gcc.

Your help will be highly appreciated.

thanx
Ram

The send(2) function on GNU/Linux takes four parameters, not three
(see the manual).  However, it is possible that your program defines
its own send() function, in this case you would have to rename it.

The warning seems to indicate a genuine bug in the code:  It doesn't
make much sense to pass a pointer value as a byte count to write(2).

(These problems are not related to GCC, you should probably ask in a
more appropriate forum such as comp.os.linux.development.apps.)

Hi, Brahmaiah,

z8k seems to be in binutils but not in gcc.

Atmel AVR is probaably the closest one-chip microcontroller.  It has
an 8-bit architecture.  I don't think it's in gcc-2.95.2.  You have to
download the current snapshot of gcc.

For 8-bit microcontrollers in general, I've seen a bunch of freely
available assemblers.  Compilers may even be there, so gcc is not the
only one to stick with.

Hope this helps.

hi,

please check SDCC compiler, i think it has a port for
both ATMEL-AVR and Z80.

Hi all, 
Currently I am going through the documents of "Porting Gcc".  
But I have got one small basic doubt, i.e.,
how should I choose between define_expand and define_insn. 

Please, see the following two defs .These are from Sparc port. I do n't understand why they
chose define_expand for cmpsi. Please explain me this part.

Thanks and regards

V.Brahmaiah
 






(define_expand "cmpsi"
  [(set (reg:CC 100)
        (compare:CC (match_operand:SI 0 "register_operand" "")
                    (match_operand:SI 1 "arith_operand" "")))]
  ""
  "
{
  sparc_compare_op0 = operands[0];
  sparc_compare_op1 = operands[1];
  DONE;
}")



(define_insn "*cmpsi_insn"
  [(set (reg:CC 100)
        (compare:CC (match_operand:SI 0 "register_operand" "r")
                    (match_operand:SI 1 "arith_operand" "rI")))]
  ""
  "cmp\\t%0, %1"
  [(set_attr "type" "compare")])

hi, I am facing some problems in writing the values directly into 
the memory mapped peripheral I/O registers. Is there any inbuilt 
memory-space qualifiers in the compiler to do this. Like if i write some 
values by using this memory space qualifiers to address 0xAB, it will 
directly write into 0xAB register or related register. please send the 
websites URLs or related documents URLs. thanking 
u Mahadev
