Writing patches in libVLC - undefined symbol error

[rakhilkt]

Hi all,

I tried to introduce a patch in my VLC source code , which I saw in the VideoLan TRAC . The reference link is
https://trac.videolan.org/vlc/attachmen ... and-.patch

The build was success , but when trying to access the new function that I added ( libvlc_video_take_snapshot_addr ) it is showing *undefined symbol* error.

Please help me in solving this.

Thanks You
Best Regards

Did you add your new function to libvlc.sym?

@sherington

Yes , I did..

The error is as follows :
*symbol lookup error : <executable_name> undefined symbol: libvlc_video_snapshot_get_addr*

Thanks...

The issue was solved. Another .so of libvlc (from /usr/lib )was been accessed by my application. When I uninstalled the current vlc installed in my system it got solved. Now it is getting linked from /usr/local/lib where my customized libvlc is present.

The command "ldd <executable_name>" helped me to find out the shared libraries associated when my program is getting executed.
