Hello

When I compile a C program using gcc, I get an a.out file. But when I type
a.out, the error is "No such command"

How do I execute the file?

Regards
Sridhar

hi i need help i have a data struct that matchs some hardwear but 
gcc is alignin it this meins it is out of sync whit the hardwear 
like 
char is              2 bytes 
long double is 12 bytes 
will thats what gcc thinks 

so i need to tell gcc not to align the data struct 

may be like 

noalign struct ........ 

the main prob is whit long double st[8] 

gcc make long double 12 bytes when it need to be 10 bytes 
  

think you 
  

struct _i386_fpu_st 
{ 
  long long  significand; 
  unsigned char       exponent   ; 
  /* unsigned long       test ; */ 

} ; 

struct _i386_fpu 
{ 
  unsigned short control ; 
  unsigned short rev0    ; 
  unsigned short status  ; 
  unsigned short rev1    ; 
  unsigned short tag     ; 
  unsigned short rev2    ; 
  unsigned long  instructionPointer ; 
  unsigned short instructionSelector ; 
  unsigned short opcode  ; 
  unsigned long  operandPointer ; 
  unsigned short operandSelector ; 
  unsigned short rev3  ; 
  long double    st[8] ; 

  /* struct _i386_fpu_st st[8] ; */ 

  unsigned long rev[400] ; 

  
} ; 

extern struct _i386_fpu * i386_fpuInit(void) ;

Hi, All:

I want to get your help on GCC for Linux on Mips.

Here is some related information:
Host: i686
 Red Hat linux 7.0  
Binutil- 2.8.1-1. 
gcc - 1.1.2-2. 
linux kernel 2.2.12.
Malta Board.
CPU R3000.
Big Endian.

When I compiled the kernel with -mcpu=r3000 -mips1, it gave me the
following error.

mips-linux-gcc -D__KERNEL__ -DCONFIG_CPU_AURORA
-I/home/wenbo/linux/include -Wall -Wstrict-prototypes -O2

Nicu met the same problem but I do not know how the problem was solved.
Thank you.
