So it seems that this issue has come up before and it is an obvious
feature to implement. In the meantime, can someone offer me the code
for a macro I can use to easily and portably set warning levels?
Thanks
pseudo code
macro(set_warning_level level)
if (MSVC)
# Set msvc type warnings
SET (CXX_FLAGS ${CXX_FLAGS} [your warnings here])
elseif(GCC)
# set gcc type warnings
SET (CXX_FLAGS ${CXX_FLAGS} [your warnings here])
else()
# we don't know this compiler
message(STATUS "Warning levels have not been defined for this compiler")
endif()
endmacro(set_warning_level level)
When this is done in CMake, that information will go into the
Modules/Platform files. So, it might be best to come up with something
that uses the same idea as that.
INCLUDE(MyPlatform/${CMAKE_SYSTEM_NAME}-${CMAKE_CXX_COMPILER_ID}-CXX
OPTIONAL )
Put MyPlatform into the CMAKE_MODULE_PATH, then create platform files in
MyPlatform/Linux-Intel-C.cmake
set(${CMAKE_CXX_COMPILER_ID}-CXX-WARNING1 -W1)
Then have the macro just add the specified warning variable. If someone
works out all the names, we can then move this stuff into CMake CVS.
