== Progress == * Maintenance (CARD-1833 2/10) - Fixing libc++abi build on AArch64 - Trying to remove a hack in ARMTargetInfo about default CPUs - Bisecting PR24292 - Working with ARM to fix it, backport * Buildbots (CARD-1823 8/10) - Working with Adhemerval on VMA 42bits sanitizer - Setting up a libc++ "full" build on the second stage, since gcc can't build it yet. 171 tests fail. - Ubuntu Vivid (39-bits VA / 4k pages) with Uboot is the winner of stability, speed and easiness. - Power outage meant I had to unbreak *a lot* of broken stuff * Background (2/10) - Code review, meetings, discussions, etc. - Some Android/TSAN/AArch64 shenanigans == Plan == Holidays all week == Issues == Yes, it does add up to 12/10, since I had to work most of Saturday and some of Sunday to fix the mess that the power cuts made on our lab. If we had generators, that wouldn't have happened.

Cross compile tool chain libs not found issue

by Yendapally Reddy Dhananjaya Reddy

Hi, I compiled the Linaro cross tool chain for arm v7 SOC and using the buildroot to create the images. When I use the downloaded precompiled tool chain from linaro releases, I am not facing any issues. But with compiled tool chain, multiple packages are failing with similar to below mentioned error. I tried building cross tool chain on both redhat and Ubuntu machines. When I see the difference of gcc -v, the cross compile is with "--host=x86_64-build_unknown-linux-gnu" and the pre compiled is with "--host=i686-build_pc-linux-gnu". I tried with "crosstool-ng-linaro-1.13.1-4.9-2014.08.tar.bz2" and "crosstool-ng-linaro-1.13.1-4.9-2014.09.tar.bz2". configure:25287: checking for MD5 in -lcrypto configure:25312: /projects/broadcom-linux/dhananjay/nas/iproc/buildroot/output/host/usr/bin/arm-linux-gnueabihf-gcc -std=gnu99 -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 conftest.c -lcrypto >&5 /projects/broadcom-linux/dhananjay/toolchain/tool9/toolchain/lib/ct-ng-linaro-1.13.1-4.9-2014.08/install/lib/gcc/arm-linux-gnueabihf/4.9.2/../../../../arm-linux-gnueabihf/bin/ld: warning: libdl.so.2, needed by /projects/broadcom-linux/dhananjay/nas/iproc/buildroot/output/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/libcrypto.so, not found (try using -rpath or -rpath-link) -bash-4.1$ uname -a Linux lab-rtp-gw-05 2.6.32-358.23.2.el6.x86_64 #1 SMP Sat Sep 14 05:32:37 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux Can somebody help me here.

abe - compiling cross aarch64 toolchain using local directory

by Virendra Kumar Pathak

Hi Linaro Toolchain Group, I am trying to compiling cross aarch64-linux-gnu toolchain using local directory (tar file) for gcc. I am using file:/// as mentioned in the https://wiki.linaro.org/ABE. ../abe/abe.sh --target aarch64-linux-gnu --build all --release 20150819 --tarbin gcc=file:///home/vpathak/arm/toolchain/build/snapshots/gcc-2015.11-5.tar.bz2 But I get following error: ERROR (#146): get_URL (not supported for .tar.* files.) ERROR (#533): get_source (file:///home/vpathak/arm/toolchain/build/snapshots/gcc-2015.11-5.tar.bz2 not a valid sources.conf identifier.) TRACE(#190): checkout () ERROR (#193): checkout (No URL given!) ERROR (#161): checkout_all (Failed checkout out of gcc.) Am I missing something ? How can we use a local directory (e.g. gcc source code) for building toolchain using abe ? Please help. Thanks. -- with regards, Virendra Kumar Pathak
