comm.o(.text+0x1030):comm.c: undefined reference to `_gethostbyaddr_r'



I know there's a way to fix it, but I don't remember the way. x.x


The EoD base is the one on MudMagic.

Samson already gave you a suggestion of what seems to be the most likely culprit:
Quote:
It doesn't have it because it's entirely possible Cygwin doesn't have the functions the header is declaring. Best bet: disable the backtracing stuff when using Cygwin.
So, you should just disable that part of the code.

Tried that, it needs to be changed to a certain format, it's not having a BrackTrace error....

Ah... err... no. You could not have tried that because it would have worked. :-)

He did not say it was generating a backtracing error. He said to disable the backtracing which means to comment out the code that does a reverse DNS lookup on incoming connections.

As I said:

The part that does the reverse DNS lookup is precisely the function that is giving you trouble. You should be able to just comment it out and things should work. Probably. :)

You might want to find a codebase for Cygwin specifically, or better yet for Win32 if that's where you're running your code.

Look at your error message, that tells you what function it is not finding in the link phase. You want to remove the part of code that refers to that function.

I don't have the code in front of me so I don't know exactly how to fix it. Could you post the lines surrounding the error?

Well........Here's the function where the error is......:


void lookup_address(DUMMY_ARG *darg)
{
struct hostent *from = 0;
struct hostent ent;
char buf[16384]; // enough ??
int err;

thread_count++;

gethostbyaddr_r( darg->buf, sizeof(darg->buf), AF_INET, &ent, buf, 16384, &from, &err);

if (from && from->h_name)
{
free_string(darg->d->host);
darg->d->host = str_dup(from->h_name);
}

/*
* Brilliant system there Mr. Jobo
*/
darg->d->lookup_status++;

free_string(darg->buf);
darg->status = 0;

thread_count--;

pthread_exit(0);
}
