Hello,

I want to use the linphone from svn trunk (with all other components from svn trunk as well). After a couple of modifications I succeeded in compiling but now when I start it I only get this error:

./linphonec: can't resolve symbol '___thenan_sf'

As far as I can see this has something to do with gcc and libgcc.a. There is a file fp-bit.c in gcc that contains a comment saying this has to be copied and used twice (one time without and one time with #define FLOAT) in order to build. Maybe there is something wrong with that?

Can somebody imagine a reason for this?

My toolchain is a nightly build from svn trunk (two weeks ago).

Thanks,

Stefan

Stefan,

Can you build and run linphone sucessfully without your modification?

Thanks for your reply. No, unfortunately I can not build it without little modifications. I posted this in this thread: blackfin.uclinux.org/gf/project/uclinux-dist/forum/?_forum_action=ForumMessageBrowse&thread_id=34412&action=ForumBrowse&forum_id=39

Anyway, the problem seems not to be in linphone binary but in the linked in libraries (from ffmpeg and linphone [libavcodec, libavutil, libavformat,...]). If I use the 2008R1.5 versions of the libraries the problem is not there.

Maybe there is something wrong with the compilation of these libs?

I had a closer look on the compiled shared libs (libavcodec.so.51.48.0 in this case).

When I use bfin-linux-uclibc-nm to get infos from the 2008R1.5 built library (first) and the svn trunk built library (second) the is a change visible that explains the above error, but why do they differ?

bfin-linux-uclibc-nm libavcodec.so.51.48.0 | grep thenan_sf -1

00322730 r ___thenan_df

00322720 r ___thenan_sf

00244a20 t _theora_decode_init

bfin-linux-uclibc-nm new/libavcodec.so.51.48.0 | grep thenan_sf -1

0031dc6c r ___thenan_df

U ___thenan_sf

0023faac t _theora_decode_init

Why is thenan_sf U (=external and undefined)?

Kind regards,

Stefan
