[Kolingba Arthur]

I have a problem installing GCC. The fact is that occures an error level
2. I don't really know what does it means because I'm a french speaking.
After running "make install" in the "objdir" I've received that error.
How can I remedy to that situation? I'm a beginner in the Linux
environment.
All regards

The make error message numbers are not very meaningful.  We need the 
text of the actual error message, which should be just above the line 
reporting a make error.  Giving us the last 20 lines or so of make 
output may be enough for us to understand what is wrong.  We will likely 
also need other info, such as what kind of machine you are using, what 
configure options you used, etc.

Wrong mailing list.  This sort of question should go to
gcc-help@gcc.gnu.org.  Thanks.

I don't know the answer to your question without a complete test
case.  However, you should be able to figure it out yourself by
reading the friendly manual:
    http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Template-Instantiation.html

Hi :

I am getting the following compilation error:

/tmp/ccIUvX3i.o(.gnu.linkonce.d._ZTV4ListIiE+0x8): undefined reference to
`List<int>::Find(int const&)'


the declaration is:

virtual int Find (const Etype &X);

and the definition is:

template <class Etype>



int 

List<Etype>::Find (const Etype &X){



	Node *P;



	for (P=List_Head; P!=NULL; P = P->Next)

		if (P->Element == X)

		{

			Current_Positioon = P;

			return 1;

		}



	 return 0;

}




Any suggestions!!!

Thanks
Abid

I'd start by downloading gcc and unpacking it and then fire up  
emacs.  :-)

After that, you can read up on what to do next:

   http://gcc.gnu.org/contribute.html

Our web site has hundreds of pages of documentation...  feel free to  
read up on what ever topics you're interested in.

Dear all!

It posible to receive function with type defined logicaly as '...false, true, true, "XXXX"' in 'attribute_spec', to
a TARGET_EXPAND_BUILTIN or TARGET_RESOLVE_OVERLOADED_BUILTIN hooks?
Criteria function return type and arguments count/type must be ignored for filtering.

Probably that you're doing something like 

printf("%s %d\n", name, age, address);

i.e. there are more arguments than there are %'s.

Static variables (and functions) are not visible to other files. So if
they're not referenced in the file in which they are defined, then they
may as well not exist.

Cheers,

[Eitan]

Hello

I have several questions:

1. Is there a list of known warnings and errors generated from the GCC on
the web? I mean a list that would shortly explain the reason for it.
Something like MSDN  - heaven forbids!!!   :-).

2. I get an annoying warning message - "warning: too many arguments for
format". What does it mean?

3. Good programing parctice - If I have a static global variable, that is
defined in one file, but not used in it - why is it a bad thing (I get a
warning)?

Thanks a lot and have a good weekend

This kind of question is completely inappropriate for this list which
is on the development _of_ GCC, not the development _with_ GCC.

Also, it is extremely impolite to ask this kind of question _anywhere_
without first trying to search for "undefined reference to `sqrt'" in
Google or a different search engine.

There is a development package that you can install as part of RH 6.1. 
During the
"Custom" install look for a package group that says "Development".

This will give you gcc and all of the required headers.  From there you
can build more recent versions of gcc.

Hi,

I have installed redhot linux 6.1.
There is no "cc" command available in that machine.
How to install  gcc c compiler without a previous version of "cc"(c
compiler)?
While running ./configure, it is asking a for cc

You have already expressed the input function of operand zero with
the matching constraint for operand 1, so you should just say"=a,a" .

Hii
	I was trying to port gcc to 8085.
	but the compiler that is generated crashes on
	some simple programs like
	case 1:
	main()
	{
		register int a;
		register int b;
		b=b+1;
	}

	though it works perfectly for 

	case 2:
	main()
	{
		register int a;
		register int b;
		a=a+1;
	}

	the reason i figured out was :
	in my machine description file
	i have specified patterns for 
	
	(define_insn "addqi3"
  	[(set (match_operand:QI 0 "register_operand" "+a,a")
        	(plus:QI (match_operand:QI 1 "register_operand" "0,0")
                 (match_operand:QI 2 "nonmemory_operand"  "i,r")))]
  		""
  		"@ 
    		ADI %2 
    		ADD %2 "
	)
	where constraint "a" specifies that this operand must be in 
	accumalator(reg no 0).

	and I also have pattern for all register to register move 
	instructions.	
	
	the rtl code that is generated for these two programs
	i m sending with this mail as an attachment.

	the problem is- (in first case )up to local register allocation 
	compiler works perfectly it also generates correct rtl codes.
	but during "reload" phase it crashes.the reason is it assigns
	accumalator(reg 0) to first variable "a" and pseudo register no "2" 
	to second variable before reload pass .
	Now during reload pass it should find out that the values are in 
	wrong registers and add instruction pattern can not be applied on it.
	so it should generate some extra register to 
	register mov instruction so that pattern for "add" instruction 
	in the md file can be applied.but it is crashing in this phase.
	
	i have read just the documentation for how to port gcc to 
	new architectures that comes with gcc package.

	I m not able to find out why the compiler is crashing.
	I would highly appreciate if u can guide me that how to find 
	out and correct error in this case .can u plz also tell me if 
	some other kind of patterns will be required in md file for this 
	particular kind of translation.I think move patterns and pattern 
	for add instruction should be sufficient.I have mapped all data
