WAS: RH9: Cannot determine ...
I'm having problems with RedHat 9. Now it could just be my install,
but someone might be able to help me. I know this is offtopic, but
the problem only reared it's head when installing DateTime. The
problem is this: in shell, I can't type a quote without a seqeunce
such as [quote][x][delete]. It seems that if I type [quote][e] I get
an 'e' with an accute. [quote] seems to have become a meta key for
accents and thus I get only the occasional quote in my Makefile. See
below.
Does anyone have any idea what's going on? I just tested it in gEdit
under X and I have exactly the same problem
The only place that it doesn't happen is in SSH, however the Makefile
is still missing heaps of single-quotes.
How do I fix this?
Thanks anyone. Following is my original email where I was trying to
track down a suspected problem with the DateTime installer. (DBI
installed without any hiccups!)
Cheers!

Redhat 9 cannot determine if we have a C compiler and so tries
defaulting to install PP Only.
When I first run 'perl Makefile.PL' I am told that this is because:
make: *** No rule to make target 'testub'. Stop.
This seems to be because we try to run (on line 34 of Makefile.PL)
system($make text$Config{obj_ext});
I checked $Config{obj_ext} at line 33 and it is 'ub' for some reason,
however when I check in a one-liner, it's '.o'.
Now if I 'make test.o' from the command line, it compiles.
So, then I went into Makefile.PL and changed line 34 to
system($make text.o);
and it writes the Makefile without any problems. However now when I
'make' I get another error:
Makefile:98: *** missing separator. Stop.
Which means that there's an error on line 98 of the Makefile. Line 97-99 is:
INSTALLSITEBIN = /usr
INSTALLVENDORBIN = /usr/bin'
installvendorhtml1=''
So the problem on line 98 would be the single quote. Where did THAT come from?
Now, I remove that and try again .. hang on, now I find that there
are heaps of lines with single quotes. OK, I'm going to stop this and
paste what seems to be the basic question at the top of this mail.

I still think it is a MakeMaker problem, has anyone reported it to them?

I guess I was not clean as what I was refering to when I made the statement of Document it. What I should have asked is Is there a place to document the test results that I have Sorry, I should have been more clear. However, I agree the this needs to be fixed in the makefile.

What does a 'man finite' get you? -D I did a man on finite here are the results: DESCRIPTION The finite() function is recommended by the IEEE-754 standard for floating-point arithmetic. finite() returns 1 only when -INFINITY x +INFINITY. Otherwise, it returns 0 (that is, when x is +-INFINITY or x is NaN). finitef() is a float version of finite(); it takes a float argument. To use this function, compile either with the -Ae option or with the -Aa and -D_HPUX_SOURCE options. Otherwise, the compiler promotes the float argument to double, and the function returns incorrect results. finitef() is not specified by any standard, but it is named in accordance with the conventions specified in the Future Library Directions section of the ANSI C standard.

FAQ outstanding questions...
Typos in POD that I spotted during FAQ development: 1) DateTime::Format::Strptime: This method is synonymous with DateTime's strptime method. 2) DateTime: DateTime does not if second values greater than 59 are valid based on current leap seconds, and invalid values simply cause an over-flow. Questions that came up in the FAQ development (you can also see these in the FAQ in the correct context if you search for QUESTION): 1) Is it worthwhile to add an optional resolution argument to compare to allow easier usage? (There was discussion, but I don't think we came down anywhere) 2) What is the overlap between DateTime::Format::Builder and DateTime::Format::Strptime? Which is preferred? 3) QUESTION How do you print non 0 or space padded years and months? [in strftime] 4) Wasn't this [the DateTime constructor croaking on bad dates] going to be overridable? 5) What happened to the module that was going to handle guessing? [at short timezone names] 6) Is there something equivalent for two days from the end of the month? Should there be? Perhaps the flag should say whether the start or end of the month offset is what matters... [In DateTime::Duration] 7) Do Sets constructed from explicit dates always get sorted? 8) Should DateTime::Set have a way to add an more explicit dates without having to make a new set and union it in? 9) Do we need a DateTime::Set clone method (ditto span, etc.)? 10) Did we ever work out how to attatch information to a date from a set? [I remember a proposal floating about, I will have to look at the archives] 11) Are we going to return an object for +/-inf or will it always be a string? [I remember some discussion here, how did it turn out?] 12) Is that true about the SpanSet? If so the docs are wrong. [What does DateTime::Set-complement() (unary) return, a Set or a SpanSet, if a Set, what does it mean (the returned type is currently a Set, but the values are odd] 13) How do I set a time zone on a set? (and span and spanset) There are some other questions about alternate implementations and business logic that I need to think about (unless someone else has any bright ideas). Thanks, -ben

Yeah, I'd like to know too. 4) Wasn't this [the DateTime constructor croaking on bad dates] going to be overridable? Not unless someone shows me a use case for it that can't be easily solved some other way. 6) Is there something equivalent for two days from the end of the month? Should there be? Perhaps the flag should say whether the start or end of the month offset is what matters... [In DateTime::Duration] my $dt = DateTime-last_day_of_month( year = 1999, month = 2 )-subtract( days = 2 ); 7) Do Sets constructed from explicit dates always get sorted? This question doesn't make sense. Sets are explicitly not an ordered entity. You're thinking of lists, which a set can be turned into. 8) Should DateTime::Set have a way to add an more explicit dates without having to make a new set and union it in? You can do $set-union($dt_object). I suppose allowing multiple arguments would make sense too. 9) Do we need a DateTime::Set clone method (ditto span, etc.)? It doesn't hurt. 10) Did we ever work out how to attatch information to a date from a set? [I remember a proposal floating about, I will have to look at the archives] No, I think this needs to be some sort of DT::Set extension. 11) Are we going to return an object for +/-inf or will it always be a string? [I remember some discussion here, how did it turn out?] It's not a string right now, it's a number that stringifies in various ways. Returning an object might be better. 13) How do I set a time zone on a set? (and span and spanset) You can't. That doesn't make sense. Set it on the objects you feed into it. -dave /*=== House Absolute Consulting www.houseabsolute.com ===*/
