a few questions about things i ran into today trying to build a qemu malta image using the latest git checkout of openwrt -- some are admittedly trivial, i just want to make sure i'm understanding everything related to them. i started with the config.malta_le config file downloaded from openwrt.org.
first, i'm aware that trying to run the pre-built qemu image from downloads.openwrt.org will fail with a kernel panic, as explained here: http://wiki.openwrt.org/doc/howto/qemu#openwrt.in.qemu.mips so during configuration, i deselected MIPS16 support. i'm not really familiar with the MIPS architecture but, as i read it, that support is really just an optimization so i can do away with it, yes? next, haven't done this yet but to save piles of time, i'm going to deselect all config settings of the form: CONFIG_PACKAGE_...=m as i understand it, those selections represent packages that will be compiled and packaged, but not built into the final rootfs. and, just to be clear, while such a final image might be deficient in all sorts of features, it should still *theoretically* boot, which is all i care about right now. next issue i ran into was this (which looks like a real bug): make[4]: Entering directory '/home/rpjday/openwrt/qemu_malta/build_dir/target-mipsel_mips32_uClibc-0.9.33.2/dump1090-2014-08-22' mipsel-openwrt-linux-uclibc-gcc -Os -pipe -mno-branch-likely -mips32 -mtune=mips32 -fno-caller-saves -fhonour-copts -Wno-error=unused-but-set-variable -msoft-float -mips16 -minterlink-mips16 -c dump1090.c In file included from dump1090.c:31:0: dump1090.h:60:25: fatal error: rtl-sdr.h: No such file or directory #include "rtl-sdr.h" ^ compilation terminated. Makefile:21: recipe for target 'dump1090.o' failed make[4]: *** [dump1090.o] Error 1 not sure what to make of that ... i checked under the build dir and there is such a header file at this location: $ find build_dir/ -name rtl-sdr.h build_dir/target-mipsel_mips32_uClibc-0.9.33.2/dump1090-2014-08-22/rtlsdr/rtl-sdr.h $ is this a known issue? for now, i'll get around it by just deselecting the dump1090 package but that shouldn't be necessary. should i file a bug report on this? another issue was one i ran into before and that i reported here: https://github.com/openwrt/packages/issues/296 a bit later this evening, i'll try applying the patch mentioned there. does anyone have any further info on this bug? finally (and this one is a bit weird), i was trying all of the above at a site where the corp firewall did not allow numerous fetching protocols, including git, ftp and wget, but i had most of the tarballs i needed already so i figured i was in good shape. not so, it turns out. partway through the build, building gcc just hung, and i tracked it down to this: $ vi build_dir/mipsel_mips32_uClibc-0.9.33.2/gcc-4.8.3/contrib/download_prerequisites MPFR=mpfr-2.4.2 GMP=gmp-4.3.2 MPC=mpc-0.8.1 wget ftp://gcc.gnu.org/pub/gcc/infrastructure/$MPFR.tar.bz2 || exit 1 tar xjf $MPFR.tar.bz2 || exit 1 ln -sf $MPFR mpfr || exit 1 ... snip ... argh. so, as i read it, there is no way to preload tarballs to get around the above, is there? configuring gcc above *requires* net access, is that correct? anyway, feel free to comment on any of the above. thanks. rday -- ======================================================================== Robert P.
