Symbian compilation

[Edwin Miguel Triana]

Hi People,
I've been trying to compile pocketsphinx for symbian, but I've had some
problems, I hope somebody can help me. I have instaled Carbide 2.3.0 and Nokia
3 SDK in Windows XP, I downloaded the pocketsphinx 0.6.1 and the sphinxbase
0.6.1 and I put in the same folder renaming to their original names
(sphinxbase and pocketsphinx), then from Carbide I imported the project using
the bld files in the group folder, then I tried to compile both and I got the
following errors:

• undefined identifier 'snd_pcm_t' ad.h /sphinxbase/include line 258 C/C++
• the file 'alsa/asoundlib.h' cannot be opened ad.h /sphinxbase/include line 128
  These are the sphinxbase errors, pocketsphinx has too much errors, but I think
  I must correct the sphinxbase first.

Also in the nmp file there the line "USERINCLUDE ..\include ..\include\s60"
but such folder doesn't exist anymore...

Can anybody give a hand? I know that currently symbian building is broken and
out of date, but I would like to fix it with your help.

Thanks in advance for your help.

I think all your problems are caused by the fact you took the release, not the
subversion snapshot. I suggest you to download the snapshot from subversion or
checkout it with svn.

It should compile fine. File include/s60 should be present there and should
configure everything as required

[Edwin Miguel Triana]

Hi Nickolay, thanks a lot for your response,
I downloaded today the sphinxbase svn snapshop version, the "s60" is there,
so, I tried to compile sphinxbase and I got several errors related with the
file.h include. I added a SYSTEMINCLUDE to the mmp file
(\epoc32\include\libc), then the error were reduced to 3. I executed the
autogen.sh file from a linux machine and the I used the same files in the
windows machine, can I do that? or is better to do all in windows?.

The error messages ar the following:

In file included from /sphinx/sphinxbase/src/libsphinxbase/util/mmio.c:65:

Thanks a lot for you help again!

Hi again,

Following the last post, the errors are from the same file where the first
error was generated. I checked the file (mmio.c) and I found the "file.h"
includes a file that references to "sys/_types.h" (from libc), but also in the
mmio.c there is a mman.h that includes "sys/_types.h", but it must be from
stdapis, but as before it has been included a file with the same name from
libc, so that could generate the errors.

Do you think that it can be the reason of the compilation errors?

Thanks again!

[Nickolay V. Shmyrev]

You clearly have include conflict where one pack of includes conflicts with
another folder. I think it's caused by

I added a SYSTEMINCLUDE to the mmp file (\epoc32\include\libc), then the
error were reduced to 3.

I think it was wrong decision to do that. You must likely needed to include
only stdapis version not libc.

[Nickolay V. Shmyrev]

And wanted to note that I updated 0.6 package which might be easier to compile
that snapshot. Release now include s60 as well.

[Edwin Miguel Triana]

Hi Nickolay,
I did some configurations, but I'm still getting errors during compilation.
The following is the log what I did:

I downloaded the sphinxbase 0.6.1, all these procedures were done on this
version.

Thanks a lot for your help again!

[Nickolay V. Shmyrev]

Well, most of the errors are easy to resolve. pthread functions are located in
a library libpthread, math functions are in the library libm. You need to add
-lm -lpthread in project compilation options or link with those libraries some
other way which works in your platform.

For example see

http://developer.symbian.org/wiki/index.php/Platform_Opening/Did_You_Know%3F/
P.I.P.S.#The_Math_Library_.28libm.29

[Edwin Miguel Triana]

Hi again,
I added that two libraries and also mediaclientaudioinputstream.lib and
mediaclientaudiostream.lib, now I have 2 errors. I don't know where can I find
the getrusage function

Creation Time Description Resource Path Location Type
1284049129622 undefined reference to getrusage' profile.c /sphinxbase/src/libsphinxbase/util line 187 C/C++ Problem 1284049129623 undefined reference togetrusage' profile.c
/sphinxbase/src/libsphinxbase/util line 223 C/C++ Problem

Thanks!

[Nickolay V. Shmyrev]

Great, you are very close!

getrusage is supposed to be present on your platform. If not, try to modify
the sources at

libsphinxbase/util/profile.c

try to comment out the function for example. It's not critical functionality

[Edwin Miguel Triana]

***Build Complete!!!!
I got the sphinxbase compiled, I added a couple of (! defined(SYMBIAN32)
in the profile.c and configured other thing in the mmp
Now I'm going to compile the pocketsphinx!
Thanks a lot!

[Nickolay V. Shmyrev]

Nice, I hope you'll share your files after that so we could update the code to
make it build from scratch.

[Edwin Miguel Triana]

Sure! I will share the files when I compile all correctly.

Now I was working in the pocketsphinx, I found my first two problems:

..\src\libpocketsphinx\fsg_lextree.c:116: illegal operands 'struct trans_list_s *' + 'int'
..\src\libpocketsphinx\fsg_lextree.c:162: 'null_trans' is not a member of class 'struct fsg_model_s'

I looked in the fsg_model.h and there are no the null_trans member...

What do you think?

I'm working with the 0.6.1 version

Thanks!

[Nickolay V. Shmyrev]

This field is there in 0.6.1 but not in the trunk. Probably you somehow trying
to compile old pocketsphinx with new sphinxbase. That will not work. Try
either new sphinxbase with new pocketsphinx or old sphinxbase with old
pocketsphinx.

[Edwin Miguel Triana]

Hi Nickolay,
The sphinxbase and pocketsphinx are compiling for Symbian using GCCE!
I used the svn version, now I'm going to start doing a program to use
pocketsphinx.
About the modifications, do you want I send you a diff file with my
modifications, or is it better to have an example running to verify that all
is ok?
Thanks

[Nickolay V. Shmyrev]

Send me the diff please.

[Nickolay V. Shmyrev]

And if you have example that would be also cool!
