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...
To build the Newlib cross-compiler, pick an install path (that is writeable). If you choose, say,/opt/riscv, then add/opt/riscv/binto yourPATH. Then, simply run the following command: ./configure --prefix=/opt/riscv make You should now be able to use riscv64-unknown-elf-gcc and...
