1 前言 XS是Perl与C的胶水语言,通过它能在Perl中创建方法,以此扩展C库中的函数或新定义的C函数,详情可参阅《官方手册:perlxs》。 XS的编译器叫做xsubpp,它用typemaps去决定如何映射C函数的参量和输出值到Perl的值中并返回。“XSUB结构(XSUB forms)”是XS接口的基本单元,一个XSUB被编译后等效于一个C函数,其...

SQL contains string - In this blog, I will explain how to check a specific word or character in a given statement in SQL Server, using CHARINDEX function or SQL Server and check if the string contains a specific substring with CHARINDEX function. An alternative to CHARINDEX() is using LIKE...
CBuild编译系统,如下特性: 1.任务解析管理器,menuconfig配置,make运行 2.比CMake更快的编译工具,同一Makefile支持Classic/Yocto组合Cross/Native共4种编译;支持指定:O输出,DESTDIR安装,DEPDIR依赖 3.处理软件编译整个过程的脚本:支持网络下载、缓存处理和镜像加速
This process will start by downloading about 200 MiB of upstream sources, then will patch, build, and install the toolchain. If a local cache of the upstream sources exists in $(DISTDIR), it will be used; the default location is /var/cache/distfiles. Your computer will need about 8 GiB...
