Question

我正在尝试通过RubyInline（https://github.com/seattlerb/rubyinline）在Ruby中运行一些C代码。

代码

    require 'inline'
    class InlineTest
      inline do |builder|
        builder.add_compile_flags('-lsqlite3')
        p builder.flags
        builder.include '<stdio.h>'
        builder.include '<sqlite3.h>'
        builder.c '
        void main(){
          sqlite3 *db;
          char *zErrMsg = 0;
          int rc;

          rc = sqlite3_open("test.db", &db);

          if( rc ) {
            fprintf(stderr, "Cannot open database: %s\n", sqlite3_errmsg(db));
            return(0);
          } else {
            fprintf(stderr, "Opened database successfully\n");
          }
          sqlite3_close(db);
          }'
       end
    end
    InlineTest.new.main

输出

["-lsqlite3"]
/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': /home/vbhv/.ruby_inline/ruby-2.3.0/Inline_InlineTest_fad58de7366495db4650cfefac2fcd61.so: undefined symbol: sqlite3_open - /home/vbhv/.ruby_inline/ruby-2.3.0/Inline_InlineTest_fad58de7366495db4650cfefac2fcd61.so (LoadError)
from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'

from /var/lib/gems/2.3.0/gems/RubyInline-3.12.4/lib/inline.rb:857:in `inline'
from main.rb:14:in `<class:InlineTest>'
from main.rb:13:in `<main>'

现在，当我将gcc与上述C代码一起使用时，'-lsqlite3'可以正常工作。如您所见，add_compiler_flags运行正常。参见输出的第一行。但是在那之后我不知道出了什么问题。

谢谢。
