详细注释
Toolchain:工具链选项
Toolchain type:Buildroot提供两种方式使用toolchain external toolthain:非Buildroot提供的交叉编译器 Buildroot toolchain:Buildroot本身编译生成的Buildroot toolchain,直接选择此项 custom toolchain vendor name:填上S3C2440 C library:C库选择,选择 glibc Kernel Headers:内核头文件,Linux 4.9.x kernel headers glibc version:glibc版本选择,2.24 Binutils Version:binutils版本:2.27 Additional binutils options:附加的 binutils 选择,不填即可 GCC compiler Version:GCC版本选择,gcc 6.x Additional gcc options:附件的GCC选项,不填写即可 Enable C++ support:使能C++支持,选上 Enable Fortran support:使能Fortran语言支持,不选 Enable compiler link-time-optimization support:是否支持LTO,不选,LTO是什么:http://blog.csdn.net/fickyou/article/details/52381776 Enable compiler OpenMP support:支持OpenMP?OpenMP用于共享内存并行系统的多处理器程序设计,OpenMP并不适合需要复杂的线程间同步和互斥的场合,OpenMp的另一个缺点是不能在非共享内存系统(如计算机集群)上使用。不选择 Enable graphite support :是否支持graphite。Graphite是应用WEB应用的一套开源的编程接口。不选择。具体看百度百科:https://baike.baidu.com/item/Graphite/9810474?fr=aladdin Build cross gdb for the host:主机上运行gdb进行调试,不选 Copy gconv libraries:拷贝 gconv库,gconv库用于在不同字符集之间进行转换。默认不选即可 Enable MMU support:使能 MMU,S3C2440支持MMU,选上 Target Optimizations:不选 Target linker options:不选 Register toolchain within Eclipse Buildroot plug-in:eclipse插件支持,不选
