当我包含'<algorithm>'和'<vector>'时崩溃RubyInline。

Crash RubyInline when I include '<algorithm>' and '<vector>'

本文关键字：gt lt vector 崩溃 RubyInline algorithm 包含      更新时间：2023-10-16

我不明白为什么RubyInline崩溃了。

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

错误：

您正在尝试使用C++代码，但是您正在运行gcc，没有任何标志来告诉它它是C++代码。

在第一个文档页面上，我们看到一个有关如何使用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)

这里的"诀窍"是：

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

这告诉gcc这是C++代码。
