Re: [Linphone-developers] Python API Compilation problems

[Loïc Maudou]

Hi,

Your last error may come from /cmake/CMakeFiles/TARGET_pylinphone.dir/build.make:107: where LINPHONE_SOURCE_DIR remains undefined.

To correct it, edit :

./Build/pylinphone/CMakeCache.txt:235:

           LINPHONE_SOURCE_DIR:UNINITIALIZED=

to :

           LINPHONE_SOURCE_DIR:STATIC=<your full path to>/linphone-cmake-builder/WORK/python-raspberry/Source/EP_linphone

Hope this will helps !

Also, I'm interested if your wheel package works !

Hi Ghislain, as I already reported few weeks ago, I had the same problem  as Loïc:

[ 95%] Performing configure step for 'TARGET_pylinphone'-- Using sysroot path: /home/dima/workspace/intercom/linphone4raspberrypi//rootfs
CMake Error at CMakeLists.txt:36 (execute_process):
  execute_process called with no value for WORKING_DIRECTORY.

nm: 'bellesip': No such file
CMake Error at CMakeLists.txt:209 (string):
  string sub-command REPLACE requires at least four arguments.

 

I'm sorry about I can't answer earlier what I've done for building.

My system is Ubuntu 14.04.

I couldn't find the rootfs You mean. Hence I built rootfs from buildroot adding all needed libraries, discovering new dependencies arised through the process of linphone-cmake-builder and starting build again from clean.

Finally all packages were compiled, but wheel package building is stopped because incomprehensible 'nm' errors.

Ghislain, Thank You for Your involvement.

Best regards, Dmitriy Alekseev

Hi Ghislain,

Thanks for your answer. I think that was already what I've done because speex is part of the linphone-cmake-builder package. I tried to recompile and copy the speex librairy to /usr/lib of the raspberry, but the error remains the same. Also, by making a wrong compilation, I had a preview of the message when he can find a librairy during the python linphone import :

/usr/lib/libswresample.so.1: version `LIBSWRESAMPLE_1' not found (required by /usr/lib/libavcodec.so.56)

I believe the origin of the problem comes from the "nm" warning during pylinphone configuration. As he cannot find the librairy, the symbols stay unknown for him. Do somebody have an idea of where is indicated the path to the librairy he had to find ? (I have to admit that my knowledge of cmake is quite weak...)

Thanks a lot for your help !

Loïc

Hi Loïc,

You need to build the speex library from the linphone branch of the git://git.linphone.org/speex.git repository.

Cheers,
Ghislain

Hi,

I'm trying to compile python API for a raspberry pi 2 working with archlinux with video display support (I heard the already compiled version cannot display video).

I'm using cross compilation from an Archlinux computer using a toolchain generated by crosstool-ng.

I did manage to finish the process, but I get this strange warning during pylinphone configuration:

nm: « linphone »: pas de tel fichier (means "No such file" in french)

nm: « mediastreamer_base »: pas de tel fichier

nm: « mediastreamer_voip »: pas de tel fichier

nm: « ortp »: pas de tel fichier

nm: « bzrtp »: pas de tel fichier

nm: « bellesip »: pas de tel fichier

nm: « linphone »: pas de tel fichier

nm: « mediastreamer_base »: pas de tel fichier

nm: « mediastreamer_voip »: pas de tel fichier

nm: « ortp »: pas de tel fichier

nm: « bzrtp »: pas de tel fichier

nm: « bellesip »: pas de tel fichier

The installation of the wheel package works, but when I try to import linphone, I get this error message :

>>> from linphone import *

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/usr/lib/python2.7/site-packages/linphone/__init__.py", line 1, in <module>

    from linphone import *

ImportError: /usr/lib/python2.7/site-packages/linphone/linphone.so: undefined symbol: speex_echo_state_blob_get_data

b_get_data

It looks like the librairy where not used by pylinphone... I've been looking for the cause those 3 days but did not manage to find it...

Thanks in advance for your help !

Loïc
