= C++ Standard
|
||||
|
||||
Since the release of C+\+11 and C++14 a common use case is to invoke the compiler to use these standards. As CMake has evolved, it has added features to make this easier and new versions of CMake have changed how this is achieved.
|
||||
|
||||
The following examples show different methods of setting the C++ standard and what versions of CMake they are available from.
|
||||
|
||||
The examples include:
|
||||
|
||||
- link:i-common-method[common-method]. A simple version that should work with most versions of CMake.
|
||||
- link:ii-cxx-standard[cxx-standard]. Using the `CMAKE_CXX_STANDARD` variable introduced in CMake v3.1.
|
||||
- link:iii-compile-features[compile-features]. Using the `target_compile_features` function introduced in CMake v3.1.

# Introduction
|
||||
|
||||
This example shows a common method to set the C++ Standard. This can be used with most versions of CMake. However, if you are targetting a recent version of CMake there are more convenient methods available.
|
||||
|
||||
The files in this tutorial are below:

|
||||
* link:main.cpp[main.cpp] - A simple "Hello World" cpp file targeting C++11.

# Concepts
|
||||
|
||||
## Checking Compile flags
|
||||
|
||||
CMake has support for attempting to compile a program with any flags you pass into the function `CMAKE_CXX_COMPILER_FLAG`. The result is then stored in a variable that you pass in.
|
||||
|
||||
For example:
|
||||
|
||||
[source,cmake]
|
||||
----
|
||||
include(CheckCXXCompilerFlag)
|
||||
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)
|
||||
----
|
||||
|
||||
This example will attempt to compile a program with the flag `=std=c++11` and store the result in the variable `COMPILER_SUPPORTS_CXX11`.
|
||||
|
||||
The line `include(CheckCXXCompilerFlag)` tells CMake to include this function to make it available for use.
|
||||
|
||||
## Adding the flag
|
||||
|
||||
Once you have determined if the compile supports a flag, you can then use the link:../../G-compile-flags/[standard cmake methods] to add this flag to a target. In this example we use the `CMAKE_CXX_FLAGS` to propegate the flag to all targets .
|
||||
|
||||
[source,cmake]
|
||||
----
|
||||
if(COMPILER_SUPPORTS_CXX11)#
|
||||
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
|
||||
elseif(COMPILER_SUPPORTS_CXX0X)#
|
||||
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")
|
||||
else()
|
||||
message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")
|
||||
endif()
|
||||
----
|
||||
|
||||
The above example only checks for the gcc version of the compile flags and supports fallback from C+\+11 to the pre-standardisation C+\+0x flag. In real usage you may want to check for C++14, or add support for different methods of setting the compile, e.g. `-std=gnu++11`

# Introduction
|
||||

This example shows how to set the C++ standard using the `CMAKE_CXX_STANDARD` variable. This is available since CMake v3.1

# Concepts
|
||||
|
||||
## Using CXX_STANDARD property
|
||||
|
||||
Setting the link:https://cmake.org/cmake/help/v3.1/variable/CMAKE_CXX_STANDARD.html[CMAKE_CXX_STANDARD] variable causes the `CXX_STANDARD` property on all targets. This causes CMake to set the appropriate flag at compille time.
|
||||
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
The `CMAKE_CXX_STANDARD` variable falls back to the closest appropriate standard without a failure. For example, if you request `-std=gnu++11` you may end up with `-std=gnu++0x`.
|
||||
|
||||
This can result in an unexpected failure at compile time.

# Introduction

This example shows how to set the C++ standard using the `target_compile_features` function. This is available since CMake v3.1

|

# Concepts
|
||||
|
||||
## Using target_compile_features
|
||||
|
||||
Calling the link:https://cmake.org/cmake/help/v3.1/command/target_compile_features.html[target_compile_features] function on a target will look at the passed in feature and determine the correct compiler flag to use for your target.
|
||||
|
||||
[source,cmake]
|
||||
----
|
||||
target_compile_features(hello_cpp11 PUBLIC cxx_auto_type)
|
||||
----
|
||||
|
||||
As with other `target_*` functions, you can specify the scope of the feature for the selected target. This populates the link:https://cmake.org/cmake/help/v3.1/prop_tgt/INTERFACE_COMPILE_FEATURES.html#prop_tgt:INTERFACE_COMPILE_FEATURES[INTERFACE_COMPILE_FEATURES] property for the target.
|
||||
|
||||
The list of available features can be found from the link:https://cmake.org/cmake/help/v3.1/variable/CMAKE_CXX_COMPILE_FEATURES.html#variable:CMAKE_CXX_COMPILE_FEATURES[CMAKE_CXX_COMPILE_FEATURES] variable. You can obtain a list of the available features using the following code:

||||
