Forum: Ruby newbie ruby installation malloc issue

hi all -

i was able to build my own 1.9.1 with no problems (except it does not
support rails)

$ ruby -v ;
ruby 1.9.1p429 (2010-07-02 revision 28523) [i686-linux]


but i tried to build 1.9.2 and during make, i got the error:

*** glibc detected *** malloc(): memory corruption: 0x09c3f2b8 ***
make: *** [.rbconfig.time] Aborted

(more detail below)

suggestions? thanks!

For what it's worth, I also had issues with compiling on my own (for
other reasons) and ended up switching to RVM, with great success:

http://beginrescueend.com/

thank you spiralofhope -

i looked into rvm, but it required a newer version of BASH and git 
(whatever that is)

it seemed easier just to build on my own.   but i may have to revisit 
rvm.

what seems so strange to me is that 1.9.1 can build successfully, but 
1.9.2 cannot!

it also seems strange that rails will work with 1.8.6, 1.9.2, but not 
1.9.1 !

I strongly urge you to install rvm.
It is an incredibly useful tool.
Well worth the trouble to set up if you plan
to write anything beyond "Hello World!" or
similarly simple programs in ruby.

Dan Nachbar

it appears in order to install rvm i have to have "git" working.

sadly, it appears to build "git" is more difficult than building ruby 
(unless anybody has a better idea)


at this rate, i may have to stick with ruby-1.8.6

IDK, I was able to download a binary of git (I'm on OSX), so super easy.

And I never had much trouble building Ruby either. Had to look up some 
flags
and do a bit of experimenting, but I didn't run into any curve balls 
(maybe
my intuitions about which flags I needed for my use case were 
sufficient) I
really didn't feel like there were any curve balls.

Ouch! Definitely try to get git installed, 1.8.6 is a deficit (though I
guess it depends why you're needing Ruby).

thanks josh.

i hope to abandon both perl and php in favor of ruby, but this is quite 
a stumbling block.

i am currently hosting with a VPS.  i am starting to wonder if maybe my 
gcc or my glibc is really out-of-date.

it does not help when the git download page seems to be permanently on 
vacation:

http://kernel.org/pub/software/scm/git/

otherwise i might get lucky and be able to snag a git-binary.

i still am very surprised that rails wont run on 1.9.1, and something 
changed so drastically in 1.9.2 to create build issues!

Yeah, that's weird, such an important resource should be made available.
There's a git irc channel on freenode where people might be able to 
offer
you more informed help than I can.



I've not looked into it, but there's another tool for managing your Ruby
versions which might not depend on git, called rbenv (
https://github.com/sstephenson/rbenv)  glancing at the readme, it looks 
like
you can build yourself, or use ruby-build to install Rubies (
https://github.com/sstephenson/ruby-build).

The instructions there have you using "git clone", but you can get 
around
that by downloading the tarball of it from the github page and then pick 
up
after that step. It might still use git after that point, I've done less
than 1 minute worth of research, so I don't know. But it might be worth
looking into.

The first hit from googling `git download` is 
<http://git-scm.com/download>;
try that.

You will definitely want/need to have git installed while you're working
with Ruby and Rails.

Ah, indeed, you're right. Well, time to bite the bullet and install from
source.

Personally, that's door number 1 for me anyway :-)
