Line "- /usr/local/bin:$PATH" is misformatted.
It must be something like "- PATH=/usr/local/bin:$PATH".
It seems something changed in tarvis-ci month ago and now this leads to:
Setting environment variables from .travis.yml
$ export PATH=
Defailt PATH is /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
so already containts /usr/local/bin.
Image "xcode8.3" contains macOS 10.12 (sierra) which has no bottles
with precompiled gcc-7 in homebrew storage.
Image "xcode9.4" is a current default with macOS 10.13 (high_sierra).

It broke because the libc++ is being built as part of *this*
build, with old gcc+libstdc++ (4.8?), but LLVM is preparing
to switch to C++14, and gcc+libstdc++ <5 are soft-deprecated.
Just the gcc update doesn't cut it, clang still uses old libstdc++.
* Add tests to verify assembler output -- Fix DoNotOptimize.
For things like `DoNotOptimize`, `ClobberMemory`, and even `KeepRunning()`,
it is important exactly what assembly they generate. However, we currently
have no way to test this. Instead it must be manually validated every
time a change occurs -- including a change in compiler version.
This patch attempts to introduce a way to test the assembled output automatically.
It's mirrors how LLVM verifies compiler output, and it uses LLVM FileCheck to run
the tests in a similar way.
The tests function by generating the assembly for a test in CMake, and then
using FileCheck to verify the // CHECK lines in the source file are found
in the generated assembly.
Currently, the tests only run on 64-bit x86 systems under GCC and Clang,
and when FileCheck is found on the system.
Additionally, this patch tries to improve the code gen from DoNotOptimize.
This should probably be a separate change, but I needed something to test.
* Disable assembly tests on Bazel for now
* Link FIXME to github issue
* Fix Tests on OS X
* fix strip_asm.py to work on both Linux and OS X like targets
* Add myself to CONTRIBUTORS under the corp CLA for Stripe, Inc.
* Add support for building with Bazel.
Limitations compared to existing CMake rules:
* Defaults to using C++11 `<regex>`, with an override via Bazel flag
`--define` of `google_benchmark.have_regex`. The TravisCI config sets
the regex implementation to `posix` because it uses ancient compilers.
* Debug vs Opt mode can't be set per test. TravisCI runs all the tests
in debug mode to satisfy `diagnostics_test`, which depends on `CHECK`
being live.
* Set Bazel workspace name so other repos can refer to it by stable name.
This is recommended by the Bazel style guide to avoid each dependent
workspace defining its own name for the dependency.
* Attempt to fix travis timeouts during apt-get.
During some builds, travis fails to update the apt-get indexes.
This causes the build to fail in different ways.
This patch attempts to avoid this issue by manually calling
apt-get update. I'm not sure if it'll work, but it's worth a try.
* Fix missing semicolons in command
* Add support for GTest based unit tests.
As Dominic and I have previously discussed, there is some
need/desire to improve the testing situation in Google Benchmark.
One step to fixing this problem is to make it easier to write
unit tests by adding support for GTest, which is what this patch does.
By default it looks for an installed version of GTest. However the
user can specify -DBENCHMARK_BUILD_EXTERNAL_GTEST=ON to instead
download, build, and use copy of gtest from source. This is
quite useful when Benchmark is being built in non-standard configurations,
such as against libc++ or in 32 bit mode.
* Add BENCHMARK_BUILD_32_BITS option and add builders to test it
* Attempt to fix travis configuration
* Make add_required_cxx_compiler_flag cause an error when the flag isn't supported
* add gcc-multilib dependancy on travis
* attempt to fix travis.yml parsing error
* Require g++-multilib instead of gcc-multilib
* Add 32 bit release configurations
* Attempt to fix libc++ travis build w/ 32 bits
* Work around CMake configuration failure on Travis
This patch adds new builders that test against GCC 6 and Clang 3.8 respectivly.
They also enable both address and undefined sanitizer. MSAN currently won't work
since it requires a sanitized STL.
Google Benchmark's Travis build currently requires "sudo" to install newer
versions of CMake and similar. See this for more details:
https://docs.travis-ci.com/user/workers/container-based-infrastructure/
Since Google Benchmark was put into Travis before 2015-01-01, it gets the
standard infrastructure implicitly, so sudo works. But anyone who forks this
repository and tries to add Travis.CI (so they can see if the build works
before creating a PR) gets broken builds before this change.
This patch cleans up our use of generic macros and also merges changes in the
build system.
It adds options -DBENCHMARK_ENABLE_TESTING and -DBENCHMARK_ENABLE_SHARED.
