[liangfok]

@david-german-tri please feel free to close if we're not planning on supporting Bazel + OSX.

[jwnimmer-tri]

Yes, we are supporting Bazel + OSX. Fixing warnings is not super high on the list though; making it support all Drake features comes first.

[liangfok]

OK. There are a couple other types of warnings that flood my terminal when I build using Bazel on OSX. Here are samples:

ld: warning: could not create compact unwind for ___dmumps_parallel_analysis_MOD_dmumps_715: stack subq instruction is too different from dwarf stack size
ld: warning: could not create compact unwind for _write_float: stack subq instruction is too different from dwarf stack size

And:

INFO: From Linking drake/common/libcond.a:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: bazel-out/osx-opt/bin/drake/common/_objs/cond/drake/common/cond.o has no symbols
warning: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: warning for library: bazel-out/osx-opt/bin/drake/common/libcond.a the table of contents is empty (no object file members in the library define global symbols)

[jwnimmer-tri]

The final item is a dup of #5145.

[liangfok]

Is there a plan for adding OSX + Bazel to either Continuous Production or Nightly Production?

Or is it already there and I simply missed it? (I was trying to verify that the same warnings show up in CI).

[jwnimmer-tri]

Other than being opt-in for PRs (aka experimental), it's only in https://drake-jenkins.csail.mit.edu/view/Bazel/job/mac-clang-bazel-nightly-release/ per https://drake-jenkins.csail.mit.edu/view/Bazel/. Yes, we are working on making it be production-supported in Continuous.

[liangfok]

Thanks. I just confirmed that all aforementioned warnings show up in CI, which is good.

[liangfok]

5662 resulted in the following warning appearing:

INFO: From Linking drake/automotive/liblane_direction.a:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: bazel-out/osx-opt/bin/drake/automotive/_objs/lane_direction/drake/automotive/lane_direction.o has no symbols

[david-german-tri]

Reassigning to @soonho-tri.

[jamiesnape]

Just noticed:

DEBUG: pkg_config.bzl:186:9: pkg-config of protobuf returned flags that we will ignore: ["-Qunused-arguments"]

Hence, targets that use protobuf have the following:

clang: warning: argument unused during compilation: '-pthread'

Since I missed that for weeks, I would advocate having the DEBUG message from pkg-config.bzlhaving the text WARNING in it so that CDash highlights and having a way to declare flags (such as -Qthread) that we know we should ignore so that the warning can be suppressed.

Also, having a platform dependent way declare flags that should be ignored could strip out the bad -pthread on Mac.

[EricCousineau-TRI]

Per f2f, still waiting for bazelbuilds upstream update. Any other warnings can be filtered out via CDash.

[EricCousineau-TRI]

Per f2f, closing this generic issue as we have the xref'd specific issues that provide better insight.

[jamiesnape]

For the record, also related is bazelbuild/bazel#5981, but I do not think it deserves a Drake issue or this issue being reopened.
