c - 将 Ruby 解释器链接到 C 程序中

Question

我正在尝试将 Ruby 解释器包含在 C 程序中。我一直使用此链接作为指南:https://silverhammermba.github.io/emberb/embed/#startup-teardown .

我在 C 中有以下代码:

#include <ruby.h>

int main(int argc, char* argv[])
{
    /* construct the VM */
    ruby_init();

    // puts "hola"
    /* Ruby goes here */

    /* destruct the VM */
    return ruby_cleanup(0);
}

问题是当我尝试编译代码时，我收到以下消息:

对 ruby_init 的引用未定义

对 ruby_cleanup 的引用未定义

您需要链接到libruby ，如链接中所述:

Embedding Ruby requires one header ruby.h, which includes a platform-specific header ruby/config.h. You will probably need to tell your compiler about the include paths for these headers. You will also need to link with the Ruby lib. On my machine, my minimal compiler options are

$ gcc -I/usr/include/ruby-2.5.0 -I/usr/include/ruby-2.5.0/x86_64-linux -lruby

Though, if available, you should really use pkg-config to get the appropriate options for your distribution:

$ pkg-config --cflags --libs ruby-2.5

将这两者结合起来，你会得到 gcc $(pkg-config --cflags --libs ruby-2.5) <files> <libs> .
