How to cross compile an gstreamer application for Yocto Dunfell 5.4.85 kernel

[KaviyaDharshini]

Hi, 

We are trying to build a gstreamer application against aarch64-fslc-linux (Yocto dunfell 5.4.85). While building the gstreamer application we are facing this below error,

No package 'gstreamer-1.0' found 
Package gstreamer-app-1.0 was not found in the pkg-config search path. 
Perhaps you should add the directory containing `gstreamer-app-1.0.pc'
to the PKG_CONFIG_PATH environment variable 
No package 'gstreamer-app-1.0' found 
Package gstreamer-video-1.0 was not found in the pkg-config search path. 
Perhaps you should add the directory containing `gstreamer-video-1.0.pc' to the PKG_CONFIG_PATH environment variable 
No package 'gstreamer-video-1.0' found 

In file included from feature_test.c:32: 
inc_header.h:57:10: fatal error: gst/gst.h: No such file or directory 

   57 | #include <gst/gst.h> 

Can you please let us know how to build the gstreamer application for Dunfell Kernel version (5.4.85)?

Thanks in advance,

what are your building steps?

We are using the following steps to build the application,

1. source /opt/fslc-xwayland/3.1/environment-setup-aarch64-fslc-linux

2. make

Our Makefile is,

SYSROOT:=/home/user/var-fslc-yocto/build_xwayland/tmp/work/aarch64-mx8m-fslc-linux/gstreamer1.0-plugins-ugly/1.16.3-r0/recipe-sysroot
CROSS_COMPILE:=aarch64-fslc-linux-
GCC:=gcc
PKG_CONFIG_PATH=${SYSROOT}/usr/lib/pkgconfig/
LDFLAGS:=`PKG_CONFIG_SYSROOT_DIR=${SYSROOT} PKG_CONFIG_PATH=${SYSROOT}/usr/lib/pkgconfig/ pkg-config --cflags --libs gstreamer-1.0 gstreamer-app-1.0 gstreamer-video-1.0`

INC_PATH= -I. -I./include

#LDFLAGS= -fPIE -pie

HEADER_FILE= ./file1.h ./file2.h ./file3.h
app.elf: file2.o file3.o
$(CROSS_COMPILE)$(GCC) --sysroot=${SYSROOT} $(INC_PATH) $(LDFLAGS) file2.o file3.o -lpthread -o app.elf

file2.o:file2.c $(HEADER_FILE)
$(CROSS_COMPILE)$(GCC) --sysroot=${SYSROOT} $(INC_PATH) $(LDFLAGS) file2.c -c -o file2.o

file3.o:file3.c $(HEADER_FILE)
$(CROSS_COMPILE)$(GCC) --sysroot=${SYSROOT} $(INC_PATH) $(LDFLAGS) file3.c -c -o file3.o

clean:
rm -rf *.elf *.o tags

Please let me know if you need any more information.

I don't know what source code you download, you can refer to the chapter 2 of enclosed file, which includes cross compiler steps
