Subject Re: Error installing rjb while installing buildr
Date Thu, 11 Dec 2008 16:02:48 GMT
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.
