Installation issues

[Eric Anderson]

When building Chisel (from the chisel-tutorial repository, via sbt), I found that the Java command line specified in the top-level Makefrag fails on my machine.  Specifically, the flag -XX:MaxPermSize=2G causes an error on my 32-bit machine.  Everything seems to be OK without that flag.  Is it necessary?

actually the problem comes in when trying to compile chisel itself.

java tends to want bigger perm size.

when and if it does fail, you can just recompile and it will continue where it left off.

so no you don't really need it.
