Hi, I am using meta-microcontroller ( https://github.com/schnitzeltony/meta-microcontroller ) to build an AVR image at build-time. The target device will then image the microcontroller at runtime. I want to put the avr utilities into the produce yocto sdk to I can do development for the microcontroller with the same tools its final build will be made with. The meta layer already provides `-native` variants of the necessary recipes. I am attempting to create `nativesdk-` variants for the necessary recipes.
I was successfully able to make `nativesdk-avr-binutils` by adding the following line to the recipe: ``` BBCLASSEXTEND =+ "nativesdk" ``` I do the same to the `avr-gcc` recipe, but I get the following compile error when I `bitbake nativesdk-avr-gcc`: ``` g++: error: unrecognized command line option ‘-fmacro-prefix-map=... ``` `avr-binutils` builds just fine with the same command line options according to `run.do_compile`, so I feel like the issue has to reside in the `avr-gcc` recipe. ```meta-microcontroller/recipes-avr/avr-gcc/avr-gcc_8.4.0.bb SUMMARY = "GNU compiler for Microchip (formerly Atmel) AVR microcontrollers" HOMEPAGE = "http://www.gnu.org/software/gcc/"; SECTION = "devel" LICENSE = "GPLv2+" LIC_FILES_CHKSUM = "\ file://COPYING;md5=59530bdf33659b29e73d4adb9f9f6552 \ file://COPYING3;md5=d32239bcb673463ab874e80d47fae504 \ file://COPYING3.LIB;md5=6a6a8e020838b23406c81b19c1d46df6 \ file://COPYING.LIB;md5=2d5025d4aa3495befef8f17206a5b0a1 \ file://COPYING.RUNTIME;md5=fe60d87048567d4fe8c8a0ed2448bcc8 \ " inherit autotools gettext texinfo BBCLASSEXTEND = "native nativesdk" DEPENDS = " \ avr-binutils \ zlib \ gawk \ gmp \ mpfr \ libmpc \ flex \ " DEPENDS_append_class-target = " ${BPN}-native" PE = "1" SRC_URI = "https://ftp.gnu.org/gnu/gcc/gcc-${PV}/gcc-${PV}.tar.xz"; SRC_URI[md5sum] = "bb815a8e3b7be43c4a26fa89dbbd9795" SRC_URI[sha256sum] = "e30a6e52d10e1f27ed55104ad233c30bd1e99cfb5ff98ab022dc941edd1b2dd4" S = "${WORKDIR}/gcc-${PV}" EXTRA_OECONF = " \ --target=avr \ --program-prefix=avr- \ --enable-languages=c,c++ \ --enable-c99 \ --enable-long-long \ --disable-bootstrap \ --disable-libmudflap \ --with-system-zlib \ --with-build-sysroot=${STAGING_DIR_TARGET} \ " EXTRA_OECONF_append_class-target = " \ --with-gnu-as \ --with-gnu-ld \ --with-as=${STAGING_BINDIR_NATIVE}/avr-as \ --with-ld=${STAGING_BINDIR_NATIVE}/avr-ld \ " export AR_FOR_TARGET = "avr-ar" export AS_FOR_TARGET = "avr-as" export DLLTOOL_FOR_TARGET = "avr-dlltool" export CC_FOR_TARGET = "avr-gcc" export CXX_FOR_TARGET = "avr-g++" export GCC_FOR_TARGET = "avr-gcc" export LD_FOR_TARGET = "avr-ld" export LIPO_FOR_TARGET = "avr-lipo" export NM_FOR_TARGET = "avr-nm" export OBJDUMP_FOR_TARGET = "avr-objdump" export RANLIB_FOR_TARGET = "avr-ranlib" export STRIP_FOR_TARGET = "avr-strip" export WINDRES_FOR_TARGET = "avr-windres" do_configure_preend_class-target() { # broken libtool here - stolen from oe-core gcc-source.inc #sed -i -e 's/hardcode_into_libs=yes/hardcode_into_libs=no/' ${S}/libcc1/configure } do_configure() { (cd ${S} && gnu-configize) oe_runconf } do_install_append() { # fix some host contamination - TBD: fix properly for file in `find ${D}/${libdir}/gcc/avr/${PV}/include`; do chown root:root $file done for file in `find ${D}/${libdir}/gcc/avr/${PV}/include-fixed`; do chown root:root $file done # remove some files conflicting with target utils rm -rf ${D}/${datadir}/locale rm -rf ${D}/${datadir}/info rm -rf ${D}/${datadir}/man/man7 } FILES_${PN} += "${libdir}/gcc/avr" FILES_${PN}-staticdev += " \ ${libdir}/gcc/avr/${PV}/*.a \ ${libdir}/gcc/avr/${PV}/*/*.a \ ${libdir}/gcc/avr/${PV}/*/*/*.a \ " # as long as there is no other libc we can pin avr-libc RDEPENDS_${PN}_class-target += " \ ${PN}-staticdev \ avr-libc \ " INSANE_SKIP_${PN} = "dev-so" ``` I feel like there's some funny-business in the dependencies that may be messing thing up, but I am not familiar enough with `-native`, and `nativesdk-` variants to say what's wrong.
