Whenever I load up Eclipse 3.0 (Milestone 8), it asks me to specify a workspace. No matter where the workspace is, when I press 'OK' it returns the error "Workspace in use, choose a different one." I've tried using both old, new, and non-existent directories, in my home dir and under the eclipse dir in /opt. I've tried chowning the /opt/eclipse-sdk-3.0_rc8/ directory to my user, and various others.

Can you reproduce this with dev-util/eclipse-sdk-3.0.0_pre8? I've removed _rc8, as it was a temporary fix and didn't build completely from source code. If your problem still persists, please reopen this bug.
rc8 build fine for me. pre8 does not: gcc -O -Wall -DSWT_VERSION=3044 -DLINUX -DGTK -I/opt/sun-j2sdk-1.4.2/include -I/opt/sun-j2sdk-1.4.2/include/linux -fpic `pkg-config --cflags gtk+-2.0` -c os.c In file included from os_structs.h:16, from os.c:17: os.h:47: error: conflicting types for `gtk_progress_bar_set_bar_style' /usr/include/gtk-2.0/gtk/gtkprogressbar.h:149: error: previous declaration of `gtk_progress_bar_set_bar_style' make: *** [os.o] Error 1 !!!
