Hi, new to Yocto, I want to develop a software that runs when you start an overo gusmtix. I read the documentation but I still have many questions. If you can answer any of them you will be helping me a lot.
I've built the gumstix-console-image<https://github.com/gumstix/Gumstix-YoctoProject-Repo>, extracted the sysroot (gumstix-sysroot) and I have adt-installer for arm (arm-sysroot) at /opt/poky/1.3 (environment-setup-armv5te-poky-linux-gnueabi) and also using bitbake and the build directory (environment-setup-armv7a-vfp-neon-poky-linux-gnueabi). I've done a hello world example and cross debugged it with Eclipse and ADT plugin and qemu. for ADT-plugin, I'm using: Built system derived toolchain > opt/poky/1.3/ sysroot Location > ~/test-yocto/arm-sysroot QEMU > ~/adt-installer/downloaded-images/zImage-qemuarm.bin and it works, but my code uses libraries like net-snmp and others not included in the arm-sysroot. Shoul I.. a) Leave the same Eclipse ADT options and manually add the libraries that I use like suggested here <https://wiki.yoctoproject.org/wiki/Training>. Then build the software and install it manually to the gumstix-console-image. b) Include the libraries and their -dev packages, build the gumstix image again, extract sysroot, change Eclipse ADT options to be Built system derived toolchain > ~/yocto/build/ sysroot Location > ~/yocto/qemu-extracted-sysroot-from-built-image Can I use the same QEMU kernel in b? I don't think so. I tried to build the image for qemuarm machine but it failed. c) forget about Eclipse and manually source the toolchain and "make". I added to the Makefile CC=arm-poky-linux-gnueabi-gcc LD=arm-poky-linux-gnueabi-ld CFLAGS=”${CFLAGS} --sysroot=<sysroot-dir>” CXXFLAGS=”${CXXFLAGS} --sysroot=<sysroot-dir>” with sysroot-dir to the gumstix-sysroot. This gave me "Recursive variable `CFLAGS' references itself (eventually). Stop." and using += didn't work either. Any tutorial (other than the gnu make<http://www.gnu.org/software/make/manual/make.html>) of how to create Makefiles for this situation? Should I change to autotools? d) A better way to do this? Thanks a lot
