Problems with installing Nios2 Linux

--- Quote Start ---

Hi,

The message

/home/developer/altera/nios2-linux/linux-2.6/arch/nios2/kernel/entry.S:138: Error: expecting control register

is made in the function

/* The function consume_arg takes a pointer into a string
   of instruction tokens (args) and a pointer into a string
   representing the expected sequence of tokens and separators.
   It checks whether the first argument in argStr is of the
   expected type, throwing an error if it is not, and returns
   the pointer argStr.  */
char *
nios2_consume_arg (char *argStr, const char *argType)
{
  char *temp;
  int regno = -1;
  
  switch (*argType)
    {
    case 'c':
      if (strncmp (argStr, "ctl", strlen ("ctl")) != 0
      && strncmp (argStr, "cpuid", strlen ("cpuid")) != 0
      && strncmp (argStr, "status", strlen ("status")) != 0
      && strncmp (argStr, "estatus", strlen ("estatus")) != 0
      && strncmp (argStr, "bstatus", strlen ("bstatus")) != 0
      && strncmp (argStr, "ienable", strlen ("ienable")) != 0
      && strncmp (argStr, "ipending", strlen ("ipending")) != 0
      && strncmp (argStr, "exception", strlen ("exception")) != 0
      && strncmp (argStr, "pteaddr", strlen ("pteaddr")) != 0
      && strncmp (argStr, "tlbacc", strlen ("tlbacc")) != 0
      && strncmp (argStr, "tlbmisc", strlen ("tlbmisc")) != 0
      && strncmp (argStr, "fstatus", strlen ("fstatus")) != 0
      && strncmp (argStr, "config", strlen ("config")) != 0
      && strncmp (argStr, "mpubase", strlen ("mpubase")) != 0
      && strncmp (argStr, "mpuacc", strlen ("mpuacc")) != 0
      && strncmp (argStr, "badaddr", strlen ("badaddr")) != 0)
    {
      as_bad (_("expecting control register"));
    }
      break;

of file "tc-nios2.c". So I think that you are calling the genuine nios2's 'gas'.

Please try to compile the 'entry.S' only, by evoking the 'nios2-***-gcc' or 'nios2-***-as' directly ?
