hello friend,
 when I use this command line to complile the helloworld.c :
 gcc $(pkg-config --cflags --libs gstreamer-0.10) helloworld.c -o helloworld
it can generate the .exe file successfully,but when I run it,there are many asserting error, some elements can not be created.the funciton "gst_element_factory_make" is returned NULL.
If I use the makefile to compile the helloworld app(makefile is supplied by the package),the app can runs OK.
 Please tell me how can I compile the app to make it runs properly? is there any compile param I missed?
Thank you!
PS: my gstreamer version is 10.23
