@@ -254,6 +254,34 @@ Several build types are possible:
* ``Release``: applies compiler optimizations and removes debug information
from the binary.
+.. note::
+
+ These built types provide suitable optimization/debug flags by
+ default but you can change them by specifying
+ ``-DARROW_C_FLAGS_${BUILD_TYPE}=...`` and/or
+ ``-DARROW_CXX_FLAGS_${BUILD_TYPE}=...``. ``${BUILD_TYPE}`` is upper
+ case of build type. For example, ``DEBUG``
+ (``-DARROW_C_FLAGS_DEBUG=...`` / ``-DARROW_CXX_FLAGS_DEBUG=...``) for the
+ ``Debug`` build type and ``RELWITHDEBINFO``
+ (``-DARROW_C_FLAGS_RELWITHDEBINFO=...`` /
+ ``-DARROW_CXX_FLAGS_RELWITHDEBINFO=...``) for the ``RelWithDebInfo``
+ build type.
+
+ For example, you can use ``-O3`` as an optimization flag by
+ specifying ``-DARROW_CXX_FLAGS_RELEASE=-O3`` for the ``Release``
+ build type. You can use ``-g3`` as a debug flag by specifying
+ ``-DARROW_CXX_FLAGS_DEBUG=-g3`` for the ``Debug`` build type.

For example, you can use ``-O3`` as an optimization flag for the
``Release``
build type by passing ``-DARROW_CXX_FLAGS_RELEASE=-O3`` .
You can use ``-g3`` as a debug flag for the ``Debug`` build type
by passing ``-DARROW_CXX_FLAGS_DEBUG=-g3`` .
