 |
|
I've tried several times to build ecj with gcj support but I keep getting the same error no matter what I do. I've been following this guide in an attempt to get Icedtea up and running. It links to this page. I can get gcj built but when I try to compile ecj with the gcj USE flag I get the following error:
| Code: |
* bootstrapping ecj with javac
Exception in thread "main" java.lang.NullPointerException

and of course, the output of emerge --info

Does anyone know what is going on? I've tried looking up info on this issue but haven't been able to come up with much. I would also like to know if there is a specific version of ecj that I should be using and what JDK I should be using for the build process. |

Just compile ecj w/o gcj useflag. At least I haven't built it with gcj.
I tried to compile IcedTea from hg with GCJ 4.3_alpha, but I get an OOM killer for gij.
EDIT: I also get an OOM when trying to compile eclipse-ecj with gcj.
Seems 2GB RAM and 1GB swap aren't enough

The problem is that ecj must be compiled with gcj support to build IcedTea. |
