# Bazel configuration for Yggdrasil Decision Forests
#
# OPTIONS
#
# Linux
#
#   linux_cpp17: Linux build. Uses C++17.
#
# Linux options:
#
#   linux_avx2: AVX2.
#
# Windows
#
#  On Windows, uncomment the output_user_root option to avoid long path issues.
#
#   windows_cpp17: Windows build. Uses C++17.
#
# Windows options:
#
#   windows_avx2: AVX2.
#
# TensorFlow Defines:
#
#   use_tensorflow_io=1: Uses tensorflow for IO operations. Otherwise, use the
#     c++ Standard Library <filesystem>. Note: <filesystem> does not exist in
#     cpp<=14 and it had some issue with gcc<=8. Required to consume dataset
#     encoded as TFRecord of TF.Examples.
#   tensorflow_with_header_lib=1: Uses tensorflow header only library. Useful to
#     use tensorflow dynamic linking. Otherwise, links tensorflow statically (if
#     tensorflow is used).
#

# Common flags.
common --experimental_repo_remote_exec

# Avoid long path issues on Windows
# startup --output_user_root=C:/tmpbld

# Flags to compile with or without recent version of Bazel.

# Required for bazel <=4, fails with bazel >= 5.
# common --incompatible_restrict_string_escapes=false
