Subject: compilacao no gcc do potato


 Pessoal,

 Uma duvida em relacao ao compilador gcc do potato.
Manda bala...


 Porque ao compilar um programa simples (teste.c) do tipo:

 
 void main(void)


 }
Bem, os padrões exigem que main seja do tipo int. Além disso este programa
não esta fazendo muita coisa, portando o compilador provavelmente ira chiar.
Tente com o código:

int main(void) {
   int a;
   return 0;
}

$cc -o teste teste.c


 -

 com as opcoes gcc -o teste teste.c -Wall

 eu estou recebendo o seguinte WARNING

 teste.c:2: warning: return type of `main' is not `int'

 Como eu poderia chegar todas as mensagens de erros do compilador ?
Presumo que queira visualizar todas as mensagens de erro. Bem, até onde eu
saiba, as mais relevantes são exibidas automaticamente.


 Obrigado

 Giuliano

A função main retorna um int, não é void, deveria ser:
int main (

 Como eu poderia chegar todas as mensagens de erros do compilador ?

Como assim chegar? Não seria checar?

 Obrigado

 That won't compile under the new one.

Which in no way implies the new gcc is buggy. The problem may very well be
your code.
Bug reports for gcc are welcome, but please make sure the problem is really
a gcc one, not one in your code.

 For instance, this assembly function won't compile under 2.95.2, but is
 fine under 2.91.66:

2.95.2 does a lot more checks relating to assembly; check out the
documentation that comes with it, or have a look at what the kernel folks
are doing.

HTH,
Ray

gcc in potato

[Christopher J. Morrone]

I am not sure where to complain about this...it probably isn't Debian's
problem, it is probably the new gcc.  The newest gcc in potato:

gcc version 2.95.2 19990906 (prerelease)

Seems to be pretty damn buggy.  There is a great store of code I have that
compiled under the last one I used:

gcc version egcs-2.91.66 Debian GNU/Linux (egcs-1.1.2 release)

That won't compile under the new one.  For instance, this assembly
function won't compile under 2.95.2, but is fine under 2.91.66:

/*  Read the pentium Time Stamp Counter register  */
unsigned long long read_TSC()
{
static union {
unsigned long dw[2];
unsigned long long counter;
} tc;

__asm__ __volatile__ (
.byte 0x0f, 0x31\n
:d= (tc.dw[1]), a= (tc.dw[0]):
:%eax, %edx
);

return tc.counter;
}

And I get this error:

arch.c: In function `read_TSC':
arch.c:30: warning: output constraint `=' for operand 0 is not at the
beginning
arch.c:30: warning: output constraint `=' for operand 1 is not at the
beginning
arch.c:30: Invalid `asm' statement:
arch.c:30: fixed or forbidden register 0 (ax) was spilled for class AREG.
make: *** [arch.o] Error 1

Should I just give up and use the gcc272 package?
