VIII. User Defined Compile Flags for HDF5 Libraries with CMake
|
||||
========================================================================
|
||||
|
||||
Custom compiler flags can be added by defining the CMAKE_C_FLAGS and
|
||||
CMAKE_CXX_FLAGS variables.
|
||||
Using a cmake script:
|
||||
set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O2")
|
||||
Defined on the configure line:
|
||||
cmake -G "Visual Studio 12 2013" -DCMAKE_C_FLAGS:STRING=-O2 ..
|
||||
|
||||
Debug symbols are enabled with configuration selections Debug or RelWithDebInfo.
|
||||
The difference between Debug and RelWithDebInfo configurations is that
|
||||
RelWithDebInfo optimizes the code similar to Release. It produces fully optimized
|
||||
code, but also creates the symbol table and the debug metadata to give the
|
||||
debugger input to map the execution back to the original code.
|
||||
RelwithDebInfo configuration should not affect the performance when the code
|
||||
is run without a debugger attached.
|
||||
|
||||
The HDF5_ENABLE_COVERAGE option will add "-g -O0 -fprofile-arcs -ftest-coverage"
|
||||
to CMAKE_C_FLAGS.

I. Managing Warnings
|
||||
========================================================================
|
||||
Compiler warnings are managed by setting the compiler flags variables.
|
||||
|
||||
Autotools uses the H5_CFLAGS and H5_CXXFLAGS, both variables set the flags nearly
|
||||
identical, along with H5_FCFLAGS for Fortran. Autotools uses the type
|
||||
and version of the compiler to determine which warning flags are used.
|
||||
However, there is an option, enable-developer-warnings, to enable extra
|
||||
flags for developers.
|
||||
|
||||
CMake uses the CMAKE_C_FLAGS and CMAKE_CXX_FLAGS, both sets are nearly
|
||||
identical, along with CMAKE_Fortran_FLAGS for Fortran. CMake has a
|
||||
minimum set of flags for GNU type compilers and for MSVC compilers. In
|
||||
addition, CMake breaks the list of flags into groups. The groups for
|
||||
GNU are roughly associated with the version of the compiler, while
|
||||
the MSVC groups are associated with the warning levels for the
|
||||
Microsoft compilers. The CMake option for enabling extra developer
|
||||
warnings is HDF5_ENABLE_DEV_WARNINGS.
|
||||
|
||||
Custom settings can be used by setting;
|
||||
Environment variables H5_CFLAGS and H5_CXXFLAGS for Autotools
|
||||
CMake defines CMAKE_C_FLAGS and CMAKE_CXX_FLAGS for CMake
