Thanks for the detailed steps.
I compiled successfully.
But, when called dhvani to read any text file, getting the following error.
Segmentation fault (core dumped)
How to make it working?
While posting bug in mailing list please try to give more information to
reproduce error.
I have compiled dhvani in my Ubuntu to help your previous configuration
issue. I just tried some thing like :
$ dhvani -t "????????"
Segmentation fault
I am not sure why it is reporting the run time error: Segmentation fault. I
used strace and gdb to trace the issue.
I took strace :
$strace dhvani -t "????????"
open(NULL, O_WRONLY|O_CREAT|O_APPEND, 0666) = -1 EFAULT *(Bad address)*
fstat64(8, {st_mode=S_IFREG|0664, st_size=35818, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb27d4000
read(8,
"\21\0\31\0Q\0h\0{\0f\0Q\0T\0;\0i\0\265\0\276\0\276\0\237\0|\0z\0"...,
8192) = 8192
brk(0x9156000) = 0x9156000
---* SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++*
Segmentation fault
Then I used gdb to see what is the problem :
$ gdb dhvani

Program received signal SIGSEGV, Segmentation fault.
0xb7e7a3e5 in fwrite () from /lib/i386-linux-gnu/libc.so.6
See the above output. It through the SIGSEGV signal from the operating
system. This means that I am trying to access an invalid memory address.
Let's take a backtrace:
(gdb) backtrace
*#0 0xb7e7a3e5 in fwrite () from /lib/i386-linux-gnu/libc.so.6*
#1 0xb7fb34a3 in process_pitch_tempo (options=0x804c3f8,

#6 0x08048c6e in main (argc=4, argv=0xbffff334) at dhvani.c:198
The above output says fwrite() call in glibc reports Segmentation fault.
so I want to switch to stack frame 1 and see where the program crashed:
(gdb) frame 1
#1 0xb7fb34a3 in process_pitch_tempo (options=0x804c3f8,
inputfile_name=0x8071da8 "/tmp/dhvani-st7188", output_filename=0x0)
at soundtouch_utils.c:136
136 fwrite(buffer, sizeof(short), read_count, out);
the program crashed inside the call to fwrite() and also note the address
of output_filename : it is output_filename=0x0 , output_filename pointing
invalid address.
(gdb) print out
$1 = (FILE *) 0x0
the value of out is 0x0, which is the NULL pointer. This is not what we
want - out should be stdout/output file. It indicates that I have to pass
proper output file to store output.
then I tried with output file name :
$ dhvani -t "????????" -o first.wav
Now it works for me.
Your problem may be something else. But this the way to get idea of why it
is giving Segmentation fault.
Thanks
