Kouhei Sutou commented on ARROW-17763:
--------------------------------------
Could you show how Bazzel specifies {{\_\_DATE\_\_}} and so on? {{export
CXXFLAGS="-D__DATE__=\\\"redacted\\\" ..."}}? {{export
CXXFLAGS="-D__DATE__=\"redacted\" ..."}}?
> [C++] Allow Bazel to pass custom __DATE__, __TIME__, and __TIMESTAMP__ flags
> to Arrow's toolchain

> Hello!
> I've been looking into incorporating Arrow into a Bazel build build project
> and have been having some challenges getting it to work.
> I've been using Bazel's
> [rules_foreign_cc|https://bazelbuild.github.io/rules_foreign_cc/main/index.html]
> to call CMake, however the build process is erroring out as [described by
> another community
> member|https://github.com/bazelbuild/rules_foreign_cc/issues/879].
> One thing that I've learned: Bazel's C++ integration will specify
> {{\_\_DATE\_\_}}, {{\_\_TIME\_\_}}, and {{\_\_TIMESTAMP\_\_}} flags to ensure
> reproducible builds.
> These values are expected to be quoted strings. However, when Arrow's
> toolchain
> [translates|https://github.com/bazelbuild/bazel/blob/5.3.0/tools/cpp/unix_cc_configure.bzl#L622-L624]
> {{CMAKE_CXX_FLAGS}} to {{ARROW_CXX_COMPILER_FLAGS}}, CMake is
> [calling|https://github.com/apache/arrow/blob/apache-arrow-9.0.0/cpp/cmake_modules/ThirdpartyToolchain.cmake#L4874]
> {{configure_file(...)}} with the {{ESCAPE_QUOTES}} option which is mucking
> up the parsing.
> Does anyone happen to have any recommendations for a workaround or a fix?
> Thank you! I appreciate everyone's efforts in continuing to develop Arrow.
> Cheers,
> Stefan
