-----------------------------------------
Summary: Do not pass GCC flags for MSVC
Key: HDFS-16681
URL: https://issues.apache.org/jira/browse/HDFS-16681
Project: Hadoop HDFS
Issue Type: Bug
Components: libhdfs++
Affects Versions: 3.4.0
Environment: Windows 10
Reporter: Gautham Banasandra
Assignee: Gautham Banasandra
The tests in HDFS native client uses the *-Wno-missing-field-initializers* flag
to ignore warnings about uninitialized members -
https://github.com/apache/hadoop/blob/8f83d9f56d775c73af6e3fa1d6a9aa3e64eebc37/hadoop-hdfs-project/hadoop-hdfs-native-client/src/main/native/libhdfspp/tests/CMakeLists.txt#L27-L28
{code}
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-missing-field-initializers")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-missing-field-initializers")
{code}
This leads to the following error on Visual C++.
{code}
[exec]
"E:\hadoop-hdfs-project\hadoop-hdfs-native-client\target\native\ALL_BUILD.vcxproj"
(default target) (1) ->
[exec]
"E:\hadoop-hdfs-project\hadoop-hdfs-native-client\target\native\main\native\libhdfspp\tests\x-platform\x_platform_dirent_test_obj.vcxproj"
(default target) (24) ->
[exec] cl : command line error D8021: invalid numeric argument
'/Wno-missing-field-initializers'
[E:\hadoop-hdfs-project\hadoop-hdfs-native-client\target\native\main\native\libhdfspp\tests\x-platform\x_platform_dirent_test_obj.vcxproj]
{code}
Thus, we need to pass these flags only when the compiler isn't Visual C++.
