Gstreamer installation from source code

[joh-4]

HI!

I was using gstreamer standard distributions from fedora repository, but needed to update them from source code to use latest version of appsrc/sink .
My problem is when I link the application against libgstapp with the option of -lgstapp-0.10, I got some link errors. It seems like I am linking to old version of gst-plugins-base library.  Error messages are as follows: ( oops! almost forgot to mentiion this. the code in main.cc is copy of exmplae code "appsink-src.c");

---------------------------------------------------------------------------------------------------
g++ -Wall -g `pkg-config --cflags gstreamer-0.10` `pkg-config --libs gstreamer-0.10` -lgstapp-0.10 -lgstinterfaces-0.10 -c main.cc
g++ -Wall -g `pkg-config --cflags gstreamer-0.10` `pkg-config --libs gstreamer-0.10` -lgstapp-0.10 -lgstinterfaces-0.10  main.o -o appsinktest
/usr/local/lib/libgstbase-0.10.so.0: undefined reference to `gst_util_seqnum_next'

/usr/local/lib/libgstbase-0.10.so.0: undefined reference to `gst_event_set_seqnum'
/usr/local/lib/libgstbase-0.10.so.0: undefined reference to `gst_event_get_seqnum'
collect2: ld returned 1 exit status
make: *** [appsinktest] Error 1
---------------------------------------------------------------------------------------------------

Is there any specific way to install the gstreamer package from source code?

The package I installed from source:
1. gstreamer-0.10.23
2. gst-plugins-base-0.10.23
3. gst-plugins-good-0.10.15 
4. gst-plugins-bad-0.10.13
5. gst-plugins-ugly-0.10.12
6. gst-ffmpeg-0.10.8         


Once I did "export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig"
What I did for every source package:

1. "./configure"
2. "make"
3. "sudo make install"

Everything was okay.

Am I missing something?

Thank you in advance!

Justin

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)
