使用Singleton模块在C中的红宝石崩溃
我试图使用Ruby's C API实施一个项目,这使我遇到了以下问题。 为使用以下代码:
#include <ruby.h>
int main(int argc, char* argv[])
{
ruby_init();
rb_require("singleton");
return ruby_cleanup(0);
}
我有一个脚本,需要单顿模块,并注意到我的程序总是崩溃,所以我将问题归结
gcc test.c `pkg-config --cflags --libs ruby`
每当我运行此操作时,我都会在rb_require(“ Singletleton”)上进行segfault(“ Singleton” )
。

我在不同的机器上使用了几个Ruby版本(2.3、2.5和2.7)尝试了一下,并始终遇到同一问题,因此目前我认为我在做错了什么。
有人可以解释一下这里的问题吗?
I was trying to implement a project using Ruby's C API which led me to the following problem. I have a script that requires the Singleton module and noticed that my program always crashes, so I boiled the issue down to using the following code:
#include <ruby.h>
int main(int argc, char* argv[])
{
ruby_init();
rb_require("singleton");
return ruby_cleanup(0);
}
Compile it using
gcc test.c `pkg-config --cflags --libs ruby`
Whenever I run this I get a segfault at the rb_require("singleton")
.

I tried this with several Ruby versions (2.3, 2.5 and 2.7) on different machines and always run into the same issue, so at the moment I think I am doing something wrong.
Can someone explain what might be the issue here?

为了使用
RB_REQUIRE
首先需要调用Ruby_init_loadpath
首先。因此,这起作用:

In order to use
rb_require
you need to callruby_init_loadpath
first.So, this works:
