我需要从使用外部库ProtocolBuffers的项目目录中禁用所有警告,该库会产生自己的警告。
这些是我收到的151条警告中的一些:
my.pb.cc: warning C4512: 'google::protobuf::FatalException' : assignment operator could not be generated
my.pb.cc: warning C4244: 'initializing' : conversion from '__int64' to 'int', possible loss of data
my.pb.cc: warning C4125: decimal digit terminates octal escape sequence
my.pb.cc: warning C4127: conditional expression is constant
my.pb.cc
xutility(2132): warning C4996: 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS.
xutility
是Visual Studio包含文件的地方。
如果将这些行添加到我的CMakeLists.txt文件中:
# Use a lower warning level threshold for autogenerated files
set(PROTOBUF_FILES_PATH "${CMAKE_CURRENT_BINARY_DIR}/src/*.pb.*")
file(GLOB PROTOBUF_FILES ${PROTOBUF_FILES_PATH})
set_source_files_properties(${PROTOBUF_FILES} PROPERTIES COMPILE_FLAGS /W2)
我禁用了已生成的pb.cc
文件中的所有警告,但ProtoBuf内部代码中还剩下15条警告,其类型为:
my.pb.cc
xutility(2132): warning C4996: 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS.
考虑到我无法修改ProtoBuf本身,如何针对[扩展名-D_SCL_SECURE_NO_WARNINGS
的文件,如何禁用这些最后的警告,可能通过添加*.pb.*
选项来调整CMakeLists.txt文件?
[不了解xutility
或Protobuf如何使用它,我建议尝试将set_source_files_properties()
调用扩展为包括COMPILE_DEFINITIONS
:
COMPILE_DEFINITIONS
