I want to write an embedded GStreamer application for an ARM processor. I have a Freescale enviroment,which contains installed gstream-0.10 & cross-compiler toolchain. I took a first Hello World application from GStream manual and tried to compile it by
arm-poky-linux-gnueabi-gcc video_1.c -o basic-tutorial-1
pkg-config --cflags --libs gstreamer-0.10
My gstreamer-0.10.pc consists:
prefix=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr
exec_prefix=/usr
libdir=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr/lib
includedir=/home/.../build_mx6q/tmp/sysroots/varsommx6q/usr/include/gstreamer-0.10
toolsdir=${exec_prefix}/bin
pluginsdir=/usr/lib/gstreamer-0.10
datarootdir=${prefix}/share
datadir=${datarootdir}
girdir=${datadir}/gir-1.0
typelibdir=${libdir}/girepository-1.0
Name: GStreamer
Description: Streaming media framework
Requires: glib-2.0, gobject-2.0, gmodule-no-export-2.0, gthread-2.0, libxml-2.0
Version: 0.10.36
Libs: -L${libdir} -lgstreamer-0.10
Cflags: -I${includedir}*
Compilation result:

Something went wrong, but I don't understand what and where. I still need a help. Thank you.
