[MacRuby-devel] #54: build on Leopard fails on readline

[Eloy Duran]

Oh hey, thanks for pointing me to it again. There's nothing wrong with  
that article I failed at properly looking at the article. I think the  
layout instantly reminded me of an article which suggested installing  
ruby into /usr which a lot of people did and consequently broke their  
installations.

Mea culpa.

So the problem of this ticket is an architecture problem. Normally  
when you just use "./configure --prefix=/usr/local" then the resulting  
binaries will only be for the current architecture it's running on. In  
this case i386. MacRuby however, is configure to be compiled for more  
architectures than just i386. This is for compatibility of your app on  
different machines and thus necessary. However, you cannot build  
something (MacRuby) for architectures which it's dependencies do not  
contain.

To sum up; your dependencies need to at least include support for the  
architectures that the product is being build for.

In this case readline was compiled without support for other archs  
than the current one, which is ok normally, but MacRuby can't be build  
for more than just i386 and so it fails.

Solutions are build MacRuby for the current arch, or make sure MacRuby  
uses libs in /usr instead of /usr/local when compiling. I wouldn't go  
with the former, it will bite you later on when deploying.

I hope this explains it a bit more. And I'll add this as a comment to  
the ticket so others won't be confused due to my error.

Cheers,
Eloy
