[gst-devel] Gstreamer installation from source code

[joh]

I figured out. I compiled the code in the different shell, which does not
know package config path.
The code was compiled okay after adding the
"PKG_CONFIG_PATH=/usr/local/lib/pkgconfig"
However, the executable does not work, even though the code is exactly the
same as example code, appsink-src.c.

The example, which is under the plug-in source tree, was compiled ok and
worked perfectly. Why the code I compiled did not work? Do I have to add
more linker options?

My makefile looks like below:

CC=g++
GST_LIBS=`pkg-config --libs gstreamer-0.10 gstreamer-app-0.10`
GST_CFLAGS= `pkg-config --cflags gstreamer-0.10 gstreamer-app-0.10`
CFLAGS=-Wall -g
BINS=appsinktest

OBJS=main.o
all: $(BINS)
main.o: main.cc
    $(CC) $(CFLAGS) $(GST_CFLAGS) $(GST_LIBS) -c main.cc
appsinktest: $(OBJS)
    $(CC) $(CFLAGS) $(GST_CFLAGS) $(GST_LIBS)  $+ -o $(BINS)
clean:
    rm -rf $(OBJS)
    rm -rf $(BINS)
