1) Go to Synaptic and install

libswt-cairo-gtk-3.4-jni
libswt-gnome-gtk-3.4-jni
libswt-gtk-3.4-java
libswt-gtk-3.4-jni
libswt-mozilla-gtk-3.4-jni

2) cd /usr/lib/jni

cp the files:

libswt-atk-gtk-3448.so
libswt-cairo-gtk-3448.so
libswt-gtk-3448.so
libswt-pi-gtk-3448.so
libswt-awt-gtk-3448.so
libswt-gnome-gtk-3448.so
libswt-mozilla-gtk-3448.so

to the areca/lib folder with names in order of appearance:

libswt-atk-gtk-3232.so
libswt-cairo-gtk-3232.so
libswt-gtk-3232.so
libswt-pi-gtk-3232.so
libswt-awt-gtk-3232.so
libswt-gnome-gtk-3232.so
libswt-mozilla-gtk-3232.so

overwriting the original ones .

3) the files:

org.eclipse.swt.gtk.linux.x86_3.2.0.v3232m.jar
org.eclipse.jface_3.2.0.I20060605-1400.jar

come from an eclipse installation actually, so if you don’t have eclipse,
download it and:

cd eclipse/plugins

and cp the org.eclipse.swt.gtk.linux.x86_64_3.4.1.v3449c.jar
into areca/lib org.eclipse.swt.gtk.linux.x86_3.2.0.v3232m.jar

and cp org.eclipse.jface_3.4.1.M20080827-2000.jar to areca/lib
org.eclipse.jface_3.2.0.I20060605-1400.jar

overwriting the original ones.

Now, the file libarecafs.so surprise, surprise is a 32 bit one, so I compiled the 64bit one.
With the 32bit one, you’ll get a couple of warnings:

09-01-22 20:44 – WARNING – com.myJava.file.metadata.posix.jni.JNIMetaDataAccessor cannot be used on this system. Got the following error : “java.lang.UnsatisfiedLinkError : /home/jordilin/areca/lib/libarecafs.so: /home/jordilin/areca/lib/libarecafs.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)”
09-01-22 20:44 – WARNING – [com.myJava.file.metadata.posix.jni.JNIMetaDataAccessor] not validated. The default metadata accessor will be used instead.

4) ./areca.sh
5) done

Note. I tested this using 6.2 pre-release, but using 6.1 should be the same.
