使用外部SDK工具链文件在VisualStudio上生成项目编译错误
CMake project compilation error on VisualStudio using external SDK toolchain file
我正在Windows机器上使用VisualStudioCMake项目。
我正在使用外部SDK，以便为Linux arm架构交叉编译我的C++程序。
我将SDK工具链添加到cmakeToolchain路径中，该路径为：
/opt/poky atmel/2.5.3/sysroots/x86_64-pokysdk-linux/usr/share/cmake/OEToolchainConfig.cmake
这是我的CMakeLists.txt文件：
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED OFF)
set(Boost_USE_STATIC_RUNTIME OFF)

Set(Boost_NO_BOOST_CMAKE ON)
#set(BOOST_ROOT "/home/ubuntu/linux4sam/poky/build-microchip/tmp/sysroots-components/cortexa5hf-neon/boost")

set(CMAKE_CXX_COMPILER ${CROSS_COMPILER_DIR}/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc)
#set(CMAKE_SYSTEM_NAME Linux)

message(STATUS "CMAKE_CXX_COMPILER='${CMAKE_CXX_COMPILER}'")
find_package(Boost 1.66.0)
if(Boost_FOUND)
message (STATUS "success!")
add_executable (CMakeProject4 "CMakeProject4.cpp" "CMakeProject4.h")
include_directories(${Boost_INCLUDE_DIRS})
target_link_libraries(CMakeProject4 ${Boost_LIBRARIES})
endif()
正如您所看到的，我正在将我的SDK编译器bin路径设置为CMAKE_C_COMPILER和CMAKE_CX_COMPILER变量。
当我调试时，我发现：

我可以在这里看到，CMake可以识别我想要使用的SDK工具链编译器，它是GNU7.3.0，但它坏了！当我打开CMakeCache.txt时，我会发现：

这是我的C++.cpp文件程序：
#include "CMakeProject4.h"
#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>
using namespace std;
int main()
{
typedef std::istream_iterator<int> in;
std::cout << "Type in any number: ";
std::for_each(
in(std::cin), in(), std::cout
<< (boost::lambda::_1 * 10)
<< "nType in another number: ");
}
但是当我尝试运行CMake以使用编译程序时
cmake -DBoost_DEBUG=ON -DCMAKE_CXX_COMPILER=/opt/poky-atmel/2.5.3/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
我有这个错误：
错误编译
请帮忙吗？
使用工具链文件时，不应该自己设置编译器。您应该让它进入工具链文件，因为它知道如何交叉编译。像CMAKE_SYSTEM_NAME和CMAKE_SYSTEM_PROCESSOR这样的东西应该留给工具链文件。

你的CMake论点应该是这样的：
cmake -DCMAKE_TOOLCHAIN_FILE=/opt/poky-atmel/2.5.3/sysroots/x86_64-pokysdk-linux/usr/share/cmake/OEToolchainConfig.cmake
