[gentoo-user] eclipse on amd64 and a general question

[Álvaro Castro]

HI!!!

I've been reading some bug reports in different pages
about problems  loading eclipse on amd64.
As it is masked, you have to unmask it both in
package.keywords and package.mask. I've tried many
combinations (as I really don't a have a clue of what
i'm doing) of ~x86 and ~amd64 architectures. Finally,
everything is unmasked under ~x86, but it doesn't
work... :-(
I've read is a bug solved in blackdown-jdk-1.4.2.03,
but it still doesn't work.


Did anyone run succesfully eclipse under AMD64.

And a more general question is the famous UNMERGING.
If I want to remove all the packages that have been
merged together with the eclipse (or any other), the
dependencies.


Thanks a lot, (and thanks for answering such a basic
question)

Yes, I have been running eclipse for some time now.
I've seen a few workarounds for the problems with eclipse in 
http://forums.gentoo.org/viewtopic-t-283429.html

You can use this:
# emerge depclean -a

BIG FAT WARNING: the success of this command relies heavily on the state of 
your system. If you have maintained your system well it will only clean the 
dependencies that are not actively used. If you haven't maintained your 
system that well it might unmerge some essential packages as well.

By actively I mean dependencies controlled by USE flags. Some packages will 
still use a library even though it's not in the packages (R)DEPEND list.

Make sure you review the list of packages before proceeding to unmerge them. 
If you see a package that doesn't belong on the unmerge list you can add it 
to the portage world file with `emerge --noreplace <packagename>`

After you've unmerged dependencies with depclean you must run the following 
command to fix broken libraries/executables that were using the a passive 
dependency.
# revdep-rebuild -p
revdep-rebuild is part of app-portage/gentoolkit
