Error installing rjb while installing buildr

[Antoine Toulme]

Hi everybody, I hit an error while trying to install buildr on a Linux
machine.

The setup of the machine is a bit particular. I have no sudo rights. I
installed ruby and rubygems from source, and tied them to the path.

uname -a returns:
Linux build 2.6.16.60-0.27-ppc64 #1 SMP Mon Jul 28 12:44:10 UTC 2008 ppc64
ppc64 ppc64 GNU/Linux

The JVM installed on this machine are IBM JVMs.

I have the nested error presented below while trying to install buildr,
which in turn tries to install rjb.

If you are into Eclipse, you can visit
https://bugs.eclipse.org/bugs/show_bug.cgi?id=258404 for more information.

Does this ring a bell for anyone ?

this is more a question on the RJB forum, not buildr.


anyways, the way RJB is built is that the file ext/load.c has
precompiler conditions based on predefined variables that define ARCH
and JVM_TYPE, based on that, RJB knows where to load libjvm.so from.


this is not a very good solution (look in the rjb forum for a post i
made there detailing why), you have two options:

1. modify ext/load.c to include another #elsif for PPC, then create a
gem and install it

2. i can send you a modified version of rjb that i have that uses an
environment variable JVM_LIB to tell it where to load the library from.
this means that you'll have to export it before running buildr


please note that in even if it finds the library, it doesn't mean it
will be able to load it (i wasn't able to load it on hpux 11.11). it's a
tricky business.

Hi Ittay, please see comments below:

I figured that later today and posted there.

Sounds tricky indeed. For other unrelated reasons, the best workaround is to
use jruby, so I won't go further down this path.
Thanks for the answer!

note that obviously, you can use jruby instead of ruby
