deflateEnd

I made the changes to the DoT code to compile on Cygwin, listed in this forum, yet I get the following when I try to compile..

I searched this forum, but I found no matches to deflateEnd or end_compression(void).

I went back to the Cygwin site thinking I might of missed a download package [end_compression(void)], and downloaded several more things that I thought could be the culprit..yet no luck.

Know how I can fix this?

The references to Deflate are to do with MCCP (Mud Client Compression Protocol) which uses the zLib library.

See this post Compiling DoT under Cygwin. The first thing it mentions is that you can't use MCCP under Cygwin. You can't have made the change suggested there.

Here's a copy and paste of my files..

DESCRIPT.H
/**************************************************************************/
//typedef unsigned int SOCKET;
/**************************************************************************/
#define DISABLE_MCCP // add this line
#ifndef DISABLE_MCCP // define this in your project to disable MCCP

UPDATE.CPP
/* Set the virtual (CPU time) timer to the standard setting, ALARM_FREQUENCY */
void reset_itimer ()
{
struct itimerval itimer;
itimer.it_interval.tv_usec = 0; /* miliseconds */
itimer.it_interval.tv_sec = ALARM_FREQUENCY;
itimer.it_value.tv_usec = 0;
itimer.it_value.tv_sec = ALARM_FREQUENCY;

return; // doesn't work under Cygwin - add this line

Here's a copy and paste of the compile output (after I do a ./configure)..

The error still occurs.

A bit depends on the order you did things.

Try getting rid of all object files and typing 'make' again.

ie. type this:

rm *.o
make
