我想使用cmake和我从此处下载的前编译的Linaro工具链交叉编译RaspberryPi2：git克隆https://github.com/raspberrypi/tools
当我尝试在项目上进行cmake时，我会收到以下错误：
/myhome/libs/raspberry/tools/arm-bcm2708/gcc-linaro-arm-linux-
gnueabihf-raspbian-x64//bin/arm-linux-gnueabihf-gcc
--sysroot=/myhome/libs/raspberry/tools/
arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/libc/
CMakeFiles/cmTC_9fb02.dir/testCCompiler.c.o -o cmTC_9fb02 -rdynamic
/myhome/libs/raspberry/tools/arm-bcm2708/gcc-linaro-arm-linux-
gnueabihf-raspbian-x64/bin/../lib/gcc/arm-linux-gnueabihf/4.8.3/../..
/../../arm-linux-gnueabihf/bin/ld: cannot find crt1.o:
No such file or directory
此文件存在以下目录中：
/myhome/libs/raspberry/tools/arm-bcm2708/gcc-linaro-arm-
linux-gnueabihf-raspbian-x64/arm-linux-gnueabihf/libc/
usr/lib/arm-linux-gnueabihf
我的cmake工具链文件看起来如下
set(CMAKE_SYSROOT "/myhome/libs/raspberry/sysroot/")
set(tools "/myhome/libs/raspberry/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/")
set(CMAKE_C_COMPILER "${tools}/bin/arm-linux-gnueabihf-gcc")
set(CMAKE_CXX_COMPILER "${tools}/bin/arm-linux-gnueabihf-g++")
set(CMAKE_EXPORT_COMPILE_COMMANDS=ON)
set(CMAKE_FIND_ROOT_PATH "${CMAKE_SYSROOT}")
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)
sysroot目录是我安装覆盆子图像的地方。我对这是否应该是覆盆子图像的根或Linaro工具链的路径感到有些困惑。
感谢您的帮助
好，问题是
set(CMAKE_SYSROOT "/myhome/libs/raspberry/sysroot/")
是一个空的目录，当我将杰西图像安装到此目录时，但是重新启动后，安装座不再在此目录中。
