• Status: RESOLVED INVALID
• Product: Gentoo Linux

When starting Eclipse SDK 3.1-r1, I get the following error log: 
 
!ENTRY org.eclipse.osgi 2005-10-17 15:14:01.129

This is because the swt library is not installed. 
 
eclipse-sdk-3.1 ebuild needs to be modified so that it depends on 
"~dev-java/swt-3.1".  Note that the dependency cannot be satisfied by 
dev-java/swt-3.2 because that version of swt uses different shared library 
names. 
 
Add "~dev-java/swt-3.1" to eclipse-sdk-3.1's depend atoms.

Additionally, it looks like /usr/lib needs to be specified in the 
"java.library.path" JVM system variable.  I don't know where in the config that 
should go, though. 

[Comment 2 Matt Whitlock 2005-10-17 13:18:57 UTC]

I got it to work by editing /usr/bin/eclipse-3.1 and changing the last line 
from: 
 
${ECLIPSE_BIN} $@ 
 
to: 
 
LD_LIBRARY_PATH="/usr/lib" ${ECLIPSE_BIN} $@ 
 
But that seems kind of hackish. 
 
I think libswt-pi-gtk-3138.so is supposed to be included in one of the JAR 
files in the /usr/lib/eclipse-3.1/plugins tree, but I don't see it in either of 
the JARs that have "swt" in their names.  Perhaps the Eclipse SDK build process 
is missing a step needed to get the native libraries included in those JARs. 

[Comment 3 Thomas Matthijs (RETIRED) 2005-10-18 03:42:24 UTC]

Eclipse builds and uses its own swt, so something must have wrong during the 
eclipse build
the swt package hasn't been around very long
(yes there are possibly plans to split eclipse-sdk up (swt,ecj,..))

do you have a log of it?

[Comment 4 Matt Whitlock 2005-10-18 22:30:54 UTC]

I re-emerged (to get a log) and now the libswt-*.so files are in the JAR 
in /usr/lib/eclipse-3.1/plugins.  Go figure.
