Subject: [tarantool-patches] [PATCH v1] Fix LTO in travis-ci
Date: Wed, 15 May 2019 15:44:56 +0300	[thread overview]
Message-ID: <06d061414ec1c1b8044deadc2ff289f123d1bccc.1557924260.git.avtikhon@tarantool.org> (raw)

Made fixes:

- Added CMAKE_EXTRA_PARAMS environment to docker's container
  runs to enable -DENABLE_LTO=ON/OFF cmake option.

- Added CC/CXX environment to docker's container runs to set
  clang for cmake.

- Changed LTO docker's image to 'debian-buster' due to LTO needed
  higher versions of packages, check for more information commit:

    commit f9e28ce4602aff3f9bb4e743b0d6167b0f8df88d
    Author: AKhatskevich <avkhatskevich@tarantool.org>
    Date:   Thu Mar 22 11:37:06 2018 +0300

- Fixed sources to avoid of failures on builds with LTO:
