如何编译/创建使用c的ruby扩展？
我想创建一个使用c的ruby扩展。 但是当我使用gcc编译它时，我收到此错误：
gcc rubyext.c -orubyext -I /usr/local/include/ruby-1.9.1/ In file included from rubyext.c:1: /usr/local/include/ruby-1.9.1/ruby/ruby.h:25:25: error: ruby/config.h: No such file or directory In file included from rubyext.c:1: /usr/local/include/ruby-1.9.1/ruby/ruby.h:107: error: 'SIZEOF_INT' undeclared here (not in a function) /usr/local/include/ruby-1.9.1/ruby/ruby.h:108: error: 'SIZEOF_LONG' undeclared here (not in a function) /usr/local/include/ruby-1.9.1/ruby/ruby.h:112: error: 'SIZEOF_VOIDP' undeclared here (not in a function) In file included from /usr/local/include/ruby-1.9.1/ruby/ruby.h:1326, from rubyext.c:1: /usr/local/include/ruby-1.9.1/ruby/missing.h:25: error: redefinition of 'struct timeval' /usr/local/include/ruby-1.9.1/ruby/missing.h:35: error: redefinition of 'struct timespec' In file included from /usr/local/include/ruby-1.9.1/ruby/intern.h:27, from /usr/local/include/ruby-1.9.1/ruby/ruby.h:1327, from rubyext.c:1: /usr/lib/gcc/x86_64-linux-gnu/4.4.3/include/varargs.h:4:2: error: #error "GCC no longer implements ." /usr/lib/gcc/x86_64-linux-gnu/4.4.3/include/varargs.h:5:2: error: #error "Revise your code to use ."

#include
任何帮助是极大的赞赏。
当然，您不能只包含头文件，您必须链接到Ruby库。
阅读Pickaxe的这一章。
也可以随意浏览我在github上的一些repos ，我写了很多C扩展。
