Hi, Amir

         Is your computer 64 bits?  It may probable caused by compiling it in 64 bits.

         I remember I meet segmentation problem as well.

I see an ETSI patch folder in the source and try to apply those patches. ( One of them will force to compile them in 32 bits ).

Besides, you need to get sdecoder compiled as well and use it after the cdecoder.

BRs, Jiang Pin

Hi Amir,

Try to run the example within a debugger to identify the exact occurrence of the segmentation fault.
If I remember correctly, the format is raw PCM, try to open the wav with an audiotool (e.g. Audacity) and save it as raw PCM.

Best Regards

I have download one sample from osmocom speech codec I  have compiled it sucesssfully then the output "ccoder.exe"
 and "cdecoder.exe" have been built. When i try to run the sample exe file using the command line, it show Segmentation fault (core dumped).

This is the how i'm running the sample
"./ccoder.exe sample.wav sample2.wav".

I'm very confusing about the input and the output file. What is the correct type file for input and the output.
Thank you for any respond
