Error compiling gstreamer app in petalinux - gstreamer

Question

I'm trying to compile a custom gstreamer app in petalinux with the next header files:
#include <stdlib.h>
#include <string.h>
#include <gst/gst.h>
#include <gio/gio.h>
The petalinux project already has the sysroot library sources populated after run:
petalinux-build --sdk
petalinux-package --sysroot
But compiling the app (petalinux-build -c myapp) I've got the next error:
| myapp.c:25:10: fatal error: gst/gst.h: No such file or directory
| #include <gst/gst.h>
| ^~~~~~~~~~~
| compilation terminated.
The make file is:
APP = myapp
# Add any other object files to this list below
APP_OBJS = myapp.o
all: build
build: $(APP)
$(APP): $(APP_OBJS)
$(CC) $(LDFLAGS) -o $# $(APP_OBJS) $(LDLIBS)
clean:
-rm -f $(APP) *.elf *.gdb *.o
%.o : %.c
$(CC) -c $(CFLAGS) -o $# $< $(shell pkg-config --cflags --libs gstreamer-1.0 glib-2.0)
And the recipe:
#
# This file is the myapp recipe.
#
SUMMARY = "Simple myapp application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "file://myapp .c \
file://Makefile \
"
S = "${WORKDIR}"
do_compile() {
oe_runmake
}
do_install() {
install -d ${D}${bindir}
install -m 0755 myapp ${D}${bindir}
Does anyone have an idea what I'm missing and how to add correctly the gstreamer paths for compilation?
EDIT
As suggested I added the DEPENDS line in the recipe:
#
# This file is the myapp recipe.
#
SUMMARY = "Simple myapp application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "file://myapp .c \
file://Makefile \
"
S = "${WORKDIR}"
DEPENDS = "glib-2.0 gstreamer1.0"
RDEPENDS_${PN} = "gstreamer1.0-plugins-base gstreamer1.0-plugins-good"
do_compile() {
oe_runmake
}
do_install() {
install -d ${D}${bindir}
install -m 0755 myapp ${D}${bindir}
But unfortunately still giving same error...any ideas what could be wrong/missing?
Thanks in advance.

Answer 1

I think you are missing the DEPENDS pointing to the GStreamer packages needed to get you code compiled. Having them at the image is not enough to have this recipe build.
You could take a look at the recipe to build the RTSP server of GStreamer (http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-multimedia/gstreamer/gstreamer1.0-rtsp-server_1.16.1.bb?h=master)
DEPENDS = "gstreamer1.0 gstreamer1.0-plugins-base"

Answer 2

I finally got it working, what I've done is instead to use the makefile to compile , is to use the recipe and more importantly to add inherit pkgconfig line, in order to force to populate sysroot during compilation, this is the final working recipe, hope it can help to someone else with same issue:
#
# This file is the myapp recipe.
#
SUMMARY = "Simple myapp application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "file://myapp .c \
file://Makefile \
"
S = "${WORKDIR}"
DEPENDS = "glib-2.0 gstreamer1.0"
RDEPENDS_${PN} = "gstreamer1.0-plugins-base gstreamer1.0-plugins-good"
inherit pkgconfig
do_compile() {
${CC} ${WORKDIR}/myapp.c -o myapp ${CFLAGS} ${LDFLAGS} `pkg-config --cflags --libs gstreamer-1.0`
}
do_install() {
install -d ${D}${bindir}
install -m 0755 myapp ${D}${bindir}
}
