Eclipse compilation problem

[Vladimír Lapáček]

Hi,

I tried to compile the Eclipse package in Ubuntu using "gcj with
generics" and got the following error:

pdebuild.jar:
   [mkdir] Created dir:
/home/vladimir/trash/eclipse/eclipse-3.2.1/source-tree/plugins/org.eclipse.pde.build/temp.folder/pdebuild.jar.bin

I know that I did not describe the compilation setup very well. I
basically used the tools that can be found at
http://people.ubuntu.com/~doko/ubuntu/feisty/i386/ and used the
Eclipse source package that can be downloaded in Ubuntu Edgy by
apt-get source eclipse

The problem only appears when using the new gcj with generics (java 5)
from the above location. When using gcj included in Ubuntu Edgy the
build goes well.

Any help appreciated.
