Hi,
I'm beginning to learn GStreamer this day.there is some problem. my linux is Kubuntu8.04.When the GStreamer installation completed,I checked it as the FAQ 5 said. It's OK.So I think my installation was correct. I tried to run the example in the application development manual(5.4). I used command "gcc -Wall $(pkg-config --cflags --libs gstreamer-0.10) xxx.c -o xxx" to compile it,and it return me that "undefined reference to `gst_element_factory_get_kalss'"compiled failed. my Gstreamer(version: 0.10) is in /usr/include/gstreamer-0.10/gst/ the Gstreamer lib is in /usr/lib/gstreamer-0.10/ I got this "undefined reference" error in using some other methods.like gst_element_unref() etc. is there something wrong with my installation? waiting for help.thinks! snYe -- Best regards ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

Hi,
If you have installed gstreamer using apt, then you will also require the devel packages for gstreamer. the devel packages are required since they have the gstreamer API headers.

You should put the pkg-config command in `` marks, as follows: "gcc -Wall `pkg-config --cflags --libs gstreamer-0.10` xxx.c -o xxx" This way the pkg-config is run first, and the output from that command is inserted into the gcc command line. -Lassi ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

It sounds like you're reading a really old version of the application development manual which refers to historic GStreamer versions. The lastest version can be found here: http://gstreamer.freedesktop.org/documentation/ Cheers -Tim ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

thinks Tim, I got the lastest version now,and found some unuseable methods
has made up, such like gst_element_unref() was not used again. But I still can't use 'gst_element_factory_get_klass()', (error:elementInfo.c:(.text+0x60): undefined reference to `gst_element_factory_get_kalss'). my source codes were copied from <5.4.1. Getting information about an element using a factory>,the newest version of the application development manaul(0.10.20.1).may any other reason to bring about that? think you.
