Hi,
I posted this question to the mjpeg-developer mailing list but didn't get
much response...
So I thought I'd try these mailing lists as well...
I was trying to use liblavplay (from the mjpeg tools) in an application I am
writing and can't seem to get it to compile due to a linking problem of
some sort. This is the compile command generated by make:
gcc -g -O2 -o eits main.o support.o interface.o callbacks.o gtktvplug.o
gtksdl.o video.o -pthread -Wl,--export-dynamic -L/usr/X11R6/lib -lgnomeui-2
-lSM -lICE -lbonoboui-2 -lxml2 -lz -lgnomecanvas-2 -lgnome-2 -lart_lgpl_2
-lpangoft2-1.0 -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0
-lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 -lbonobo-2 -lgconf-2 -lgnomevfs-2
-lbonobo-activation -lORBit-2 -lm -llinc -lgmodule-2.0 -ldl -lgobject-2.0
-lgthread-2.0 -lglib-2.0 -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread
-lXv -lmjpegutils -llavfile -llavjpeg -llavplay -llavrec
I am linking against
@PACKAGE_LIBS@ $(INTLLIBS) @SDL_LIBS@ -lXv -lmjpegutils -llavfile -llavjpeg
-llavplay -llavrec
in the Makefile.am
but get the following error:
/usr/local/lib/liblavfile.so: undefined reference to `mjpeg_error_exit1'
/usr/local/lib/liblavfile.so: undefined reference to `mjpeg_warn'
/usr/local/lib/liblavfile.so: undefined reference to `mjpeg_error'
/usr/local/lib/liblavfile.so: undefined reference to `mjpeg_info'
/usr/local/lib/liblavfile.so: undefined reference to `mjpeg_debug'
collect2: ld returned 1 exit status
make[2]: *** [eits] Error 1
These functions are from the: mjpeg_logging.c file in the util directory. As
far as I can tell form the makefile these functions should be included in
libmjpegutils.... Am I overlooking something??
Also I've gotten Ronald Butje's gtktvplug widget to compile and run in gtk
2.0 (a huge 3 line change) so if anyone else is interested I can post the
changes and compile info.... There is a slight bug that sometimes the window
needs to be moved to get the video to display. Not sure why, but when it is
resized/etc sometimes u need to move the window slightly to get video to
display.... If anyone knows why this is happening please let me know...
Thanks
macca
