Question

我不明白为什么RubyInline会崩溃。

class CPPCode
    inline do |builder|
        builder.include '<algorithm>'
        builder.include '<vector>'
        builder.c 'int test(){return 1;}'
    end
end

错误：

生成的C ++文件：

#include "ruby.h"
#include <algorithm>
#include <vector>

# line 58 "/home/lionzxy/RubymineProjects/app/models/book.rb"
static VALUE test(VALUE self) {
return INT2FIX(1);}

    VALUE c = rb_cObject;
    c = rb_const_get(c, rb_intern("Book"));
    c = rb_const_get(c, rb_intern("CPPCode"));

    rb_define_method(c, "test", (VALUE(*)(ANYARGS))test, 0);

}

您尝试使用C ++代码，但是您在没有任何标志的情况下运行gcc，告诉它它是C ++代码。

在first documentation page上，我们看到了一个如何使用C ++代码的示例：

require 'inline'
class MyTest
    inline(:C) do |builder|
        builder.include '<iostream>'
        builder.add_compile_flags '-x c++', '-lstdc++'
        builder.c '
            void hello(int i) {
                while (i-- > 0) {
                    std::cout << "hello" << std::endl;
                }
            }'
    end
end

t = MyTest.new()
t.hello(3)

＆＃34;技巧＆＃34;这是：

builder.add_compile_flags '-x c++', '-lstdc++'

告诉gcc这是C ++代码。

当我包含＆＃39; <algorithm>＆＃39;时崩溃RubyInline和＆＃39; <vector>＆＃39;
