Tk installation woes

M

Miro

Greetings, gents.

I picked up Mastering Perl/Tk at my local library, and, anxious to try
it out on my home Slackware system, I downloaded Tk from CPAN, and
cd'ed into the directory.

perl Makefile.PL worked with no problem, however "make" gives me
this...

cc -c -I.. -I/usr/X11R6/include -I. -Ibitmaps -I/usr/X11R6/include -
D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector

CORE" -Wall -Wno-implicit-int -Wno-comment -Wno-unused -

Xlib.h:22:15: error: conflicting types for 'XKeycodeToKeysym'
/usr/include/X11/Xlib.h:1694:15: note: previous declaration of
'XKeycodeToKeysym' was here
make[1]: *** [Xlib_f.o] Error 1
make[1]: Leaving directory `/home/miro/Downloads/Tk-804.027/pTk'
make: *** [pTk/libpTk.a] Error 2

I'm not exactly a Perl (or manual compilation) guru, can anyone tell
me what I must do?

It's not a Perl problem but might be a bug in the C code
of Tk, probably the one discussed here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613188

There's also a proposed patch by Dominique Dumont I append in full
at the end. It consists of inserting into 'perl-tk-804.029/pTk/Xlib.h'
(or 'perl-tk-804.027/pTk/Xlib.h' in your case) a line with

#ifndef _X11_XLIB_H_

before the line with

extern XFontStruct *XLoadQueryFont _ANSI_ARGS_((Display *, const char *));

and another line with

#endif /* _X11_XLIB_H_ */

after the line with

extern int XSubtractRegion _ANSI_ARGS_((Region, Region, Region));

I can't promise that this will really fix the problem but it
might be worth a try.

Wow. An unfixed bug that crippling in Tk? I thought it had been around
since the dawn of time? Linus's Law shudders.
Anywhoo, your patch worked great in that 'make' now took of without a
hitch (even though I have no idea what the hack I just :^)
I owe you and the community much gratitude.

Actually, as far as I understand the comments in the patch it's
about a new version of XLib Tk wasn't yet tested against - and
the guys taking care of the Tk stuff can't forsee everything
that's going to happen to things they necessarily have to depend
upon but have no influence over. If you closely look at the docu-
mentation you might even find some information against what they
tested and if you use something newer things can become "inter-
esting"...
