您对 mlpack 有疑问:
cmake_minimum_required(VERSION 2.8.5)
project(mlpack C CXX)
# Ensure that we have a C++11 compiler.
include(CMake/CXX11.cmake)
check_for_cxx11_compiler(HAS_CXX11)
if(NOT HAS_CXX11)
message(FATAL_ERROR "No C++11 compiler available!")
endif(NOT HAS_CXX11)
enable_cxx11()
特别是对于 CMake/CXX11.cmake:
macro(check_for_cxx11_compiler _VAR)
message(STATUS "Checking for C++11 compiler")
set(${_VAR})
if((MSVC AND (MSVC10 OR MSVC11 OR MSVC12)) OR
(CMAKE_COMPILER_IS_GNUCXX AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 4.6) OR
(CMAKE_CXX_COMPILER_ID STREQUAL "Clang" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 3.1) OR
(CMAKE_CXX_COMPILER_ID STREQUAL "Intel" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 12.0))
set(${_VAR} 1)
message(STATUS "Checking for C++11 compiler - available")
else()
message(STATUS "Checking for C++11 compiler - unavailable")
endif()
endmacro()
因此,您必须将 MSVC14 添加到条件:
macro(check_for_cxx11_compiler _VAR)
message(STATUS "Checking for C++11 compiler")
set(${_VAR})
if((MSVC AND (MSVC10 OR MSVC11 OR MSVC12 OR MSVC13 OR MSVC14)) OR
(CMAKE_COMPILER_IS_GNUCXX AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 4.6) OR
(CMAKE_CXX_COMPILER_ID STREQUAL "Clang" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 3.1) OR
(CMAKE_CXX_COMPILER_ID STREQUAL "Intel" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 12.0))
set(${_VAR} 1)
message(STATUS "Checking for C++11 compiler - available")
else()
message(STATUS "Checking for C++11 compiler - unavailable")
endif()
endmacro()
尝试这个。
