Very simple code has weird errors

[Israel]

Having some trouble with this code I found in Phrack 61. It looks very simple though.

Code: Select all

int _init(void)
{
        _dumm ();
        cmn_err(1,"evil: successfully installed");
        return 0;
}


I simply renamed the _init function to local_int and the error went away. However that did not work for _dumm. I have tried many different #include files too and can't get cmn_err working either. Any help would be appreciated.

You must defer linking to the final step by using the -c option on your code pieces

Code: Select all

gcc -c -o evil.o evil.c
