Hi,
I'm very new to C programming and need to get a program compiled and running. The code was given to me but I keep having issues compiling it. It says:
warning #2027: Missing prototype for 'print_p56_long_summary'.
warning #2027: Missing prototype for 'print_p56_short_summary'.
The code is pretty long so Ill just put the parts it references:
/*
============================================================================
void print_p56_long_summary(char *file, SVP56_state state, double al_dB,
~~~~~~~~~~~~~~~~~~~~~~~~~~~ double NdB, double gain, double ratio,
long N, long N1, long N2, long bitno);
Print full summary of P.56 statistics
Parameter:
~~~~~~~~~~
file ..... File name
state .... P.56 state variable
al_dB .... active level in dB
NdB ...... desired dB level for output
gain ..... gain to equalize file to desired level
ratio .... ratio of maximum number representable in the system (based on
the number of bits, or resolution, of the input speech file)
to the range of the input signal. E.g., for a 16 bit system
with a +-1 signal range, ratio = 32760 / 1.0.
N ........ number of samples per block
N1 ....... number of first block processed in the file
N2 ....... total number of blocks processed from the file
bitno .... number of bits per sample (input signal resolution)
Returns
~~~~~~~
None

I appreciate any help you can give me.
Thanks
