Compile problem: Curses::Widgets HaroldWho 09-24-2007

I have a problem compiling the Curses::Widgets module. I'm on Slackware
12.0 if that matters. The Curses module compiled OK and passed the testing
phase.

The 'perl Makefile.PL' step seems OK. The 'make test' seems OK too, but when
the Curses color test screen appears and I press a key (as instructed), the
app terminates with 'Error 255.'

I have an app that uses Curses::Widgets, and it fails with the message:

"Curses function 'chgat' called with too many arguments at
/usr/lib/perl5/site_perl/5.8.8/Curses/Widgets/ButtonSet.pm line 305."

I'm stumped. Any suggestions?

FYI, here's what the compile and test showed on the console:

root@Beagle:/opt/src/CursesWidgets-1.997# perl Makefile.PL

What version of ncurses are you using? Here it's 5.6.20061217, find out with
$ ncurses5-config --version

Maybe your installed version is too old? Here the chgat call looks as
follows:
$ man curs_attr
[...]
int chgat(int n, attr_t attr, short color,
const void *opts)
[...]


Rgds,

My version is 5.6.20070217. Not too old, but perhaps too new :-)

So, I'm still at a loss. I guess I'll have to dummy up some simple scripts
for Curses and Curses::Widgets to see what makes the failure happen.

Thanks for the suggestion.

Well, what does your manpage say (man curs_attr)? Or the source? It's easy
to find the reason for that error, you just have to look. The solve the
problem might be another issue.

My man page says the same as yours. The source pm's for Widgets look OK, but
I'm not really sophisticated enough at reading perl code to be confident.

You've given me an idea though. I'll go back to my old versions of those
pm's on another partition and do a 'diff'. Maybe that'll shed some light.

Thanks for following this.
