I've been trying to compile the Opus codec to run on Blackfin 527. Unfortunately, while compiling one of the codec's source files, ccblkfn.exe crashes. Here's the the message it gives me:

 

"C:\Program Files (x86)\Analog Devices\VisualDSP 5.0\ccblkfn.exe" -c ..\..\module\opus\silk\VAD.c -file-attr ProjectName=opus-blackfin -O -Ov100 -g -save-temps -path-output .\Debug -ED -no-extra-keywords -structs-do-not-overlap -no-multiline -D HAVE_CONFIG_H -I .. -I ..\..\module\opus -I ..\..\module\opus\include -I ..\..\module\opus\celt -I ..\..\module\opus\silk -I ..\..\module\opus\silk\float -I ..\..\module\opus\silk\fixed -double-size-32 -decls-strong -warn-protos -c99 -si-revision 0.2 -proc ADSP-BF527 -o .\Debug\VAD.doj

At end of source: : internal error: Uncaught exception Assertion failed raised

          at ../../../bril/optimiser/eval.c:4112 (in pass available_values:2

          during compilation of _silk_VAD_GetSA_Q8). Please submit a bug

          report with this message, the command line used, type of machine and

          the output of the compiler when you add -ED -v to the command line.

          Please also send us the pre-processed file that is generated by the

          -ED option (the file generated is named <original_filename>.i)

 

1 catastrophic error detected in the compilation of "..\..\module\opus\silk\VAD.c".

 

I am working on a 64-bit version of Windows 7. I followed the above instruction and recompiled the file with the requested settings. Find attached an archive which includes files:

- containing the command used to compile the file (.bat),

- containing the message produced by the compiler during the unsuccessful compilation (.txt),

- intermediate preprocessed file.

 

Please, let me know if I can help by providing any more details.
