Compilation error: Type #18 expected a ")"

Hello,

I am trying to run this C code which work perfectly fine in visual studio 8.

but when tried to run in CCS 5.3 i get multiple compilation error

eg.

Type #18 expected a ")" cutoff.c /src line 56 C/C++ Problem

the code line is

pitch_freq_log_Q7 = sSMLAWB( pitch_freq_log_Q7, sSMULWB( sLSHIFT( -quality_Q15, 2 ), quality_Q15 ),
pitch_freq_log_Q7 - ( lin2log( sFIX_CONST( VARIABLE_HP_MIN_CUTOFF_HZ, 16 ) ) - ( 16 << 7 ) ) );

here,

sSMLAWB, sLSHIFT, sFIX_CONST, VARIABLE_HP_MIN_CUTOFF_HZ are macros.

lin2log is a function.

i am running this on simulator in CCS for C64xx.

this works f9 in Visual studio then why is this error in CCS ?

am new to CCS, kindly help.

Thanks,

Vinod

Most likely one of those macros is defined differently for C64xx and has an error.

Preprocess the file as described at http://processors.wiki.ti.com/index.php/Preprocess_Complex_Source_Code_for_Bug_Submissions and post the corresponding line in the preprocessed output.

I am having a similar problem. I created a .pp file as described in the wiki link above, but I'm not sure how it will help. I don't see any corresponding lines for the variables in my c code that are having issues.

I'm sure my problem has an easy fix, I just don't know what it is. I have the following 2 error messages on 50 lines:

"#18 expected a ")"

#41 expected an identifier

Any suggestions are appreciated.

Both errors are on each line.

The compiler is telling you that the program has invalid syntax. Most likely, the parentheses in some macro aren't balanced, or perhaps you are using some keyword the compiler doesn't recognize.

I asked for the preprocessed file because without it, I can't point out the exact spot where the error is.

If you have a preprocessed file which reproduces the problem, cut lines from it that are irrelevant to the error message until you are down to one line that reproduces the problem. This should be illuminating.

Another suggestion ... Add the option --verbose_diagnostics and build again. That should make the meaning of the error messages much more clear.

Thanks and regards,
