Hi, I have installed the glib and gstreamer-0.10.21 in /users/rajesh/gstreamer_build/GLIB and /users/rajesh/gstreamer_build/GSt respectively I am trying to build the helloworld example in gstreamer-0.10.21/tests/examples/manual/ I have written my own make file as follows. where $HOME is /users/rajesh/ MAKEFILE **************************************************************************************** CC = gcc GLIB_INCLUDE_DIR =-I/users/rajesh/gstreamer_build/GLIB/include/glib-2.0  -I/users/rajesh/gstreamer_build/GLIB/lib/glib-2.0/include GLIB_LIB_DIR = -L/users/rajesh/gstreamer_build/GLIB/lib/ GST_INCLUDE_DIR=-I$(HOME)/gstreamer_build/GST/include/gstreamer-0.10/ -I/usr/include/libxml2/ GST_LIB_DIR=-L$(HOME)/gstreamer_build/GST/lib PKG_CONFIG_PATH=$(HOME)/gstreamer_build/GST/lib/pkgconfig/ GST_GLIB_LIBS= -lgstreamer-0.10 -lgobject-2.0 -lgthread-2.0 -lrt -lgmodule-2.0 -ldl -lglib-2.0 -lxml2 all: clean playbin playbin:         $(CC) $(GST_INCLUDE_DIR) $(GLIB_INCLUDE_DIR) -o playbin playbin.c  $(GST_LIB_DIR) $(GLIB_LIB_DIR) $(GST_GLIB_LIBS) -pthread clean:         rm -rf playbin *.o ********************************************************************************************************************** the executable playbin is built The I set the LD_LIBRARY_PATH as follows $set LD_LIBRARY_PATH=($HOME/gstreamer_build/GST/include/gstreamer-0.10/:$HOME/gstreamer_build/GST/lib/:$LD_LIBRARY_PATH) when I try to run playbin It says it cannot find the shared library libgstreamer-0.10.21 ldd produces the following output $ldd ./playbin         libgstreamer-0.10.so.0 => not found         libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0x00c65000)         libgthread-2.0.so.0 => /usr/lib/libgthread-2.0.so.0 (0x00688000)         librt.so.1 => /lib/tls/librt.so.1 (0x005bf000)         libgmodule-2.0.so.0 => /usr/lib/libgmodule-2.0.so.0 (0x00c60000)         libdl.so.2 => /lib/libdl.so.2 (0x008c9000)         libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0x00af6000)         libxml2.so.2 => /usr/lib/libxml2.so.2 (0x07d22000)         libpthread.so.0 => /lib/tls/libpthread.so.0 (0x009ba000)         libc.so.6 => /lib/tls/libc.so.6 (0x00778000)         /lib/ld-linux.so.2 (0x0075b000)         libz.so.1 => /usr/lib/libz.so.1 (0x008cf000)         libm.so.6 => /lib/tls/libm.so.6 (0x008a4000) I don't understand 1.why it is not able to detect libgstreamer-0.10.21 2.why the default library paths are being set for other libarires Any clues on this?
