by Jeffrey Walton

Thanks guys, that was it. I did not realize the build system was omitting the flags.

Please forgive my ignorance. I'm working on a Pine64 dev-board Pine64 supplies Linaro's GCC 4.9.2 toolchain. I am catching a compile error, and I am trying to determine why.

=== This Week === Back from month long holiday had a surgery during this period. Add Pine64 as tester to LLDB buildbot [TCWG-1011] [3/10] -- Configure Pine64 with Ubuntu 16.04 image -- Configure network on Pine64 to be used with LLDB buildbot -- Configure Pine64 for AArch32 mode execution -- Configure LLDB buildbot to include Pine64 as tester in both AArch32 and AArch64 modes. -- Run buildbot with Pine64 and monitor stability Monitor LLDB buildbot for minimum down time. [TCWG-712] -- Return from break reset buildbot and testers. Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] [2/10] -- Some tests pass when run individually. -- Some tests fail only when run in testsuite, similar steps pass when run using LLDB commandline. LLDB Arm/AArch64 Investigate and fix testsuite crashes (Pine64 Crashes) [TCWG-792] [1/10] -- LLDB crashing unexpectedly on Pine64 as well. -- Initial investigation suggests test run fine individually and in single thread mode. Meetings and other Miscellaneous Activities [1/10] -- Browse through email backlog. -- Prepared a future ToDo list. BUD17 Travel - Schengen visa application for Budapest, Hungary. [3/10] -- Information gathering and correspondance. -- Form filling and preparation supporting documentation. -- Application submission. -- Interview date is on 10th Jan 2017. === Next Week === Investigate LLDB testsuite failures on Pine64 target (AArch32 and AArch64 modes) [TCWG-1012] -- Continue to investigate, possible fix trivial issues and mark rest as xfail with appropriate bug reports. LLDB Arm/AArch64 Investigate and fix testsuite crashes (Pine64 Crashes) [TCWG-792] -- Find a reliable reason to the issue as this hampers our buildbot work. BUD17 Travel - Schengen visa application for Budapest, Hungary. -- Budapest visa interview travelling to Islamabad 9 - 10 Jan 2017.
