I have spent a few hours on this and thus am asking for help. Any help is
appreciated :-)
I am attempting to port an ltib project to yocto from here:
http://www.imxcv.blogspot.com/2012/10/video-to-texture-streaming-part-3-imx6.html
Here is my recipe:
DESCRIPTION = "Video to texture streaming - i.MX6 Processor."
SECTION = "base"
DEPENDS = "libgstreamer libxml2"
#LICENSE = "GPLv2"
#I'll change the License back to GPLv2, using CLOSED below to prevent
errors during recipe build
LICENSE = "CLOSED"
SRC_URI =
"git:///home/ashwin/fsl/imx6texture/i.MX6-Video-Streaming-Texture;protocol=file"
SRCREV = "${AUTOREV}"
S = "${WORKDIR}/src/"
EXTRA_OEMAKE = "'CC=${CC}' 'CFLAGS=${CFLAGS}'"
do_compile() {
oe_runmake
}
do_install(){
oe_runmake install DESTDIR=${D} SBINDIR=${sbindir} MANDIR=${mandir}
\
INCLUDEDIR=${includedir}
install -d ${D}${bindir}
}
FILES_${PN} = " \
${bindir}/imx6texture \
"
Some notes:
I am using a local git repo for now. Here is my makefile for the project:
CFLAGS += -Wall -DLINUX=1 -DEGL_API_FB=1
-I/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite/usr/include/gstreamer-0.10
-I/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite/usr/include/glib-2.0/
CXXFLAGS += -Wall -DLINUX=1 -DEGL_API_FB=1

-I/home/ashwin/fsl-community-bsp/build/tmp/sysroots/imx6qsabrelite/usr/include/libxml2
OBJS = wrapper.o \
gstcontrol.o \
glutils.o \

main.o
all: $(OBJS)
#This is my attempt to create an executable called main.out from main.o
install:
$(CC) -o main.out main.o
clean:
rm -rf *o
I am able to compile the 5 source files listed above. During the link and
install phase, I get the following errors:

Questions:
1. So it seems that some basic linking is not being done (like glibc
(operator new) as well as linking the GL symbols). Where do I specify these
libraries in the recipe?
2.Also, if you note above, I had to manually include the -I include paths
in the CXXFLAGS flags inside the makefile. Can this be done automatically
in the recipe? Isn't that what the DEPENDS variable is for?
3. The above took a long time for me to figure out. I am still learning the
ins and outs of writing recipes. If I want to compile a quick program
natively on the imx6q running yocto, what recipes should I build to give me
the native gcc toolchain on the imx6Q
Thanks!
