Hi,
I'm trying out ruby-dl and it looks great. However,
I get a seg fault when calling funcs that take parameters.
Anyone can spot the problem?
Here's a transcript showing what I did:
$ cat test.c
#include <stdio.h>
extern void hello()
{
printf("Hello!\n");
}
extern int one()
{
return 1;
}
extern int inc(int n)
{
return (n+1);
}
feldt@novomundo1 /tmp/using_ruby_dl/test
$ gcc -shared -o test.so test.c
feldt@novomundo1 /tmp/using_ruby_dl/test
$ cat test.rb
require 'dl/import'
module Test
extend DL::Importable
dlload 'test.so'
extern "void hello()"
extern "int one()"
extern "int inc(int)"
end
Test.hello
p Test.one
p Test.inc(2)
feldt@novomundo1 /tmp/using_ruby_dl/test
$ ruby test.rb
Hello!
