I spent and continue to spend days on packaging Pharo for Ubuntu so that everyone can forget about dependencies and 32 vs. 64 issues. So why do you keep on talking about this complex and undocumented method of installing Pharo? Just execute what is documented on the pharo.org website and you are guaranteed to have the latest version of the VM working whatever your Ubuntu is (provided it is still supported by Canonical) -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

That's why I prefer the ia32-libs approach... You may also need a libcairo:i386, and a few more stuff (did someone had a problem with odbc?) The base pharo has very few dependencies (libc6:i386) but the plugins have more and it becomes a bit more involved to chase them. > Anyway, missing deps are easily found using ldd.

Except that arithmetic on Fraction isExact, or should I say is: #exact, while on Float is not, so definitely a Float is not a Fraction, even if its internal representation is a Fraction. 2013/6/25 Igor Stasenko <siguctua(a)gmail.com> > On 25 June 2013 13:34, Nicolas Cellier > <nicolas.cellier.aka.nice(a)gmail.com> wrote: > > That does not answer my problem. > > 2 both is: #fraction (with 1 denominator) and is: #integer so how do you > > implement? > > or: [super is: #number] ? > > > > i know you can give plenty of ideas how you would do it, like: > > #(foo bar baz) includes: yourQuery > > but i wouldn't recommend it :) > > > Btw i find it really strange, why for Integer it answers true, > but not for Floats > > i actually would expect that: > > 10e50 isFraction > 0.5 isFraction > should also answer true > > because the floating-point numbers, which we are using in computers, > can be represented by a fraction. > And only those, which cannot be represented by fraction (like Pi) > should answer false. > So, please, fix it, and then we will think how to better implement > polymorphic check with single #is: method :) > > > > > 2013/6/25 Igor Stasenko <siguctua(a)gmail.com> > >> > >> On 25 June 2013 12:47, Nicolas Cellier > >> <nicolas.cellier.aka.nice(a)gmail.com> wrote: > >> > But in some cases, you will end up with an object that is more than > one > >> > thing: > >> > - a Number > >> > - an Integer > >> > - a Fraction > >> > For example 0 shall answer yes to these 3. > >> > So ^foo == #specialName just does not work, or you end up with caseOf: > >> > > >> > >> err, why? > >> > >> if you define it like: > >> > >> Number>>is: symbol > >> ^ symbol == #number > >> > >> > >> 0 is: #number => true > >> 0.0 is: #number => true > >> 0/1 is: #number => true > >> ? > >> > >> It is actually up to implementor how to his own classes should process > >> #is: message. > >> The only invariant (which imo best one), that Object should always > >> answer false to #is: message no matter what parameter you passed, to > >> avoid any ambiguous cases and keep things simple and easy to remember. > >> That means, that unless you override this method in own class, its > >> instances will always answer false to #is: message. > >> And when you override it, you are free to define it the way you like... > >> > >> MyClass>>is: foo > >> ^ foo class == self class > >> or > >> MyClass>>is: foo > >> ^ foo class name == self class name > >> or > >> > >> MyClass>>is: foo > >> ^ foo isKindOf: MyClass > >> > >> (no limits to imagination :) > >> > >> -- > >> Best regards, > >> Igor Stasenko. > >> > > > > > > -- > Best regards, > Igor Stasenko. > >

Thiery must be correct I am must be missing i386 libraries cause my ubuntu is amd64 , how I get them ? Also can someone update the site so ubuntu users don't have the same problem as me ? Just basic info how to install pharo on linux should be enough.
