Building a stand-alone, static, debug'-g' version of GStreamer
 
|
I'd like to build a stand-alone, static, debug'-g' version of GStreamer so I can step through simulations, bugs, and new plugin development with a source-debugger. I'd like to install the executables, libraries, includes, and debug versions of plugins in a directory ~/BIN under my user account. I'd also like to leave the system GStreamer working so I can switch back and forth between development and a known, working system.
Is there a better way of doing this? Please let me know. This is what I've been able to figure out on my own: __________________________________________ I've successfully built gstreamer-0.10 ( from http://gstreamer.freedesktop.org/src/ ). And I've installed my local copy to compile and build against by doing: $ cd ~/DEV/gstreamer-0.10/ $ ./configure --enable-debug --enable-gst-debug --enable-profiling --enable-parse --enable-option-parsing --enable-static --disable-shared --prefix=/home/user/BIN $ make $ make install So now I've got my own debug version of the Gstreamer launcher, inspector, includes, and libs. Everything appears to be happy, so far. $ cd ~/BIN $ tree -d . |-- bin |-- include | `-- gstreamer-0.10 | `-- gst | |-- base | |-- check | |-- controller | |-- dataprotocol | `-- net |-- lib | |-- gstreamer-0.10 | `-- pkgconfig |-- libexec | `-- gstreamer-0.10 `-- share |-- aclocal [[...]] __________________________________________ Next I downloaded the gst-plugins-base-0.10, built, and statically linked against my development version: $ cd ~/DEV/gst-plugins-base-0.10/ $ export GST_CFLAGS="-I/home/user/BIN/include/gstreamer-0.10 \ -I/home/user/BIN/include/gstreamer-0.10/gst -I/usr/include/glib-2.0 \ -I/usr/lib/glib-2.0/include -I/usr/include/libxml2" $ export GST_LIBS="-pthread -static -L/home/user/BIN/lib -lgstreamer-0.10 \ -lxml2 -lgthread-2.0 -lrt -lgobject-2.0 -lglib-2.0" $ ./configure --enable-debug --enable-static --enable-profiling --disable-shared --prefix=/home/user/BIN $ make $ make install __________________________________________ I can verify my debug versions of the gst-plugins-base were correctly installed and visible: $ cd ~/BIN/bin/ $ ./gst-inspect audioresample: audioresample: Audio resampler playback: subtitleoverlay: Subtitle Overlay [[...]] audiotestsrc: audiotestsrc: Audio test source alsa: alsasink: Audio sink (ALSA) alsa: alsasrc: Audio source (ALSA) alsa: alsamixer: Alsa mixer coreelements: valve: Valve element [[...]] typefindfunctions: audio/x-musepack: mpc, mpp, mp+ typefindfunctions: video/x-ms-asf: asf, wm, wma, wmv staticelements: bin: Generic bin staticelements: pipeline: Pipeline object Total count: 26 plugins, 178 features However, when I try inspect one of the plugins, or use ./gst-launch, I get "GLib-GObject-CRITICAL" errors: $ ./gst-inspect alsasink (gst-inspect-0.10:30950): GLib-GObject-WARNING **: cannot register existing type `GstObject' (gst-inspect-0.10:30950): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (gst-inspect-0.10:30950): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0' failed (gst-inspect-0.10:30950): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (gst-inspect-0.10:30950): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0' failed __________________________________________ Is there something obvious I've done wrong? Where to go next? Since I've got debug turned on, I can get lot's of information. Spewage from turning on GST_DEBUG indicates that it's using the correct library in ~/BIN/lib. It even says it "looks good", just before it hangs  $ export GST_DEBUG=5 $ ./gst-inspect alsasink 0:00:00.000448594 31059 0xa0bf070 INFO GST_INIT gst.c:613:init_pre: Initializing GStreamer Core Library version 0.10.36 0:00:00.000485536 31059 0xa0bf070 INFO GST_INIT gst.c:614:init_pre: Using library installed in /home/user/BIN/lib 0:00:00.000495006 31059 0xa0bf070 INFO GST_INIT gst.c:624:init_pre: Linux ubuntu 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 [[...]] 0:00:00.904396010 31156 0x8232070 DEBUG GST_PLUGIN_LOADING gstplugin.c:1293:gst_plugin_load_by_name: looking up plugin alsa in default registry 0:00:00.904410607 31156 0x8232070 DEBUG GST_PLUGIN_LOADING gstplugin.c:1296:gst_plugin_load_by_name: loading plugin alsa from file /home/user/BIN/lib/gstreamer-0.10/libgstalsa.so 0:00:00.904419281 31156 0x8232070 DEBUG GST_PLUGIN_LOADING gstplugin.c:737:gst_plugin_load_file: attempt to load plugin "/home/user/BIN/lib/gstreamer-0.10/libgstalsa.so" 0:00:00.905904303 31156 0x8232070 LOG GST_PLUGIN_LOADING gstplugin.c:834:gst_plugin_load_file: Plugin 0x824ba20 for file "/home/user/BIN/lib/gstreamer-0.10/libgstalsa.so" prepared, calling entry function... 0:00:00.905922400 31156 0x8232070 LOG GST_PLUGIN_LOADING gstplugin.c:841:gst_plugin_load_file: Plugin 0x824ba20 for file "/home/user/BIN/lib/gstreamer-0.10/libgstalsa.so" prepared, registering... 0:00:00.905933556 31156 0x8232070 LOG GST_PLUGIN_LOADING gstplugin.c:540:gst_plugin_register_func: plugin "/home/user/BIN/lib/gstreamer-0.10/libgstalsa.so" looks good (gst-inspect-0.10:866): GLib-GObject-WARNING **: cannot register existing type `GstObject' (gst-inspect-0.10:866): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (gst-inspect-0.10:866): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0' failed __________________________________________ And, here's a backtrace from gdb where the program is hanging: __________________________________________ $ ps -aux | grep inspect fritzkatz 32146 0.0 0.1 9552 3036 pts/0 S 19:12 0:00 /home/user/BIN/bin/gst-inspect-0.10 alsasink $ gdb /home/user/BIN/bin/gst-inspect-0.10 32146 [[...]] warning: Unable to find dynamic linker breakpoint function.
