Re: [Swarm-Support] compiling swarm: TclInterp.m:244: warning: passing arg 2 of `Tcl_Merge' from incompatible pointer type

[Paul Johnson]

HM. That is an error I've only seen when I try swarm against tcltk 8.4. 
 My understanding was that only 8.4 started more strictly checking 
variable types. Maybe something I did to try and fix that probelm in 8.4 
found its way into that package you are trying to use, and your info 
below indicates you have 8.3. I bet that's it.

One possibility is to step back one unit and build Swarm that I'm sure 
was OK, because it was before the changes for Macintosh and such started 
entering my consciousness:

http://lark.cc.ku.edu/~pauljohn/Swarm/Swarm-2.2x_RPMSforRH8.0/swarm-2.1.141.20021019.tar.gz

Perhaps the easiest (most expedient) thing to do is get rid of the 
-Werror flag in the Makefile for that one directory that is giving you 
trouble. Since this is just a Warning, not an Error, it should be ok. 
Recall that Werror has the effect of making all warnings be treated as 
errors.

On the other hand, you could stick with the snapshot you have, and try 
to bug shoot the tcltk thing.  The more I think about it, the more I'm 
sure that I did something in that Windows snapshot that I did not expect 
would affect tcl 8.3 users. I made a tcl related patch of the tcltk 
related changes that I thought were needed.  I'm attaching it to this 
email because I don't have time to put it on the net somewhere. I'm 
going to get on a plane to go to Swarmfest right now.

Maybe you could see if you can reverse that patch on the swarm source. I 
bet the tcl problem goes away.
