Can't rebuild examples/fvadwav.c

[4t4nner]

After building and installing I try:

cp examples/fvadwav.c ~/tmp_proj/
g++ -v -g fvadwav.c

and get an error:

my /usr/include is:

how can I reproduce your example code without errors?

Update

I found solution

g++ -v -g fvadwav.c -lsndfile -lfvad

Please, add it to description.

I am also facing the same issue while making executable of fvadwav.c as "fvadwav" to run wavtest.sh in tests folder.

when I run this :
gcc fvadwav.c -o fvadwav

I got the same erro as yours:
/tmp/ccwtRlGE.o: In function process_sf': fvadwav.c:(.text+0x13f): undefined reference to fvad_process'

collect2: error: ld returned 1 exit status

Can you confirm how did you solve that issue from above command:
g++ -v -g fvadwav.c -lsndfile -lfvad

the solution is not working for me even I run your solution I get following error:
fvadwav.c: In function ‘bool process_sf(SNDFILE*, Fvad*, size_t, SNDFILE**, FILE*)’:
fvadwav.c:32:31: error: invalid conversion from ‘void*’ to ‘double*’ [-fpermissive]

Thanks

[4t4nner]

Had you "-lsndfile -lfvad" flags in your run attempt?

[alamnasim]

Thanks for the reply.

Yes It worked for me.
