Hi, how can I get past this error? it occurs during compilation in
libspeex's lpc.c when fixedpoint is defined during the computation for
autocorrelation. The error occurs twice.
..\..\libspeex\lpc.c(149) : error C2296: '<<=' : illegal, left
operand has
type 'spx_word32_t'
I don't really know what's going on inside the functions so I'm
afraid to
make any changes. Thank you!
for (j=0;j<n;j++)
ac0 = ADD32(ac0,SHR32(MULT16_16(x[j],x[j]),8));
ac0 = ADD32(ac0,n);
shift = 8;
while (shift && ac0<0x40000000)
{
shift--;
ac0 <<= 1;
}
ac_shift = 18;
while (ac_shift && ac0<0x40000000)
{
ac_shift--;
ac0 <<= 1;
}
for (i=0;i<lag;i++)
{
d=0;
for (j=i;j<n;j++)
{
d = ADD32(d,SHR32(MULT16_16(x[j],x[j-i]), shift));
}
ac[i] = SHR32(d, ac_shift);
}
