Okay so after much digging around I found that Aptana needs libgtkembedmoz.so to run (Aptana team please fix this, just include the file in the next build please!!!).
Work around:
Well xulrunner (the new version) doesn't include libgtkembedmoz.so file. So after much Googling I found that Thunderbird does. So I YUM install thunderbird and went to check if the file libgtkembedmoz.so was there. (BTW: thunderbird version 2.0.0.18 on CentOS 5). Yeah it's there.
So I have a script that looks for the libgtkembedmoz.so file
[SCRIPT]
#!/bin/bash
# Set path for the Mozilla SWT binding
MOZILLA_FIVE_HOME=${MOZILLA_FIVE_HOME%*/}
if false && [ -n "$MOZILLA_FIVE_HOME" -a -e $MOZILLA_FIVE_HOME/libgtkembedmoz.so ]; then
:
elif [ -e /usr/lib/mozilla/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/mozilla
elif [ -e /usr/lib/firefox/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/firefox
elif [ -e /usr/lib/xulrunner/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/xulrunner
elif [ -e /usr/lib/esc-1.0.0/xulrunner/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/esc-1.0.0/xulrunner
elif [ -e /usr/lib/mozilla-firefox/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/mozilla-firefox
elif [ -e /usr/lib/mozilla/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/mozilla
elif [ -e /usr/lib/thunderbird-2.0.0.18/libgtkembedmoz.so ]; then
export MOZILLA_FIVE_HOME=/usr/lib/thunderbird-2.0.0.18
else
$DIALOGW \
--title="Integrated browser support not working" \
--text="This Eclipse build doesn't have support for the integrated browser."
[ $? -eq 0 ] || exit 1
fi
# libraries from the mozilla choosen take precedence
LD_LIBRARY_PATH=$MOZILLA_FIVE_HOME${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
# Do the actual launch of Aptana Studio
exec ./AptanaStudio
[/SCRIPT]
make it executable (chmod 755 scriptname) and run.
Note:
Just cjeck to make sure you have the right version of the program and/or that the path works.
[user@machine]# ls /usr/lib/thunderbird-2.0.0.18/libgtkembedmoz.so
/usr/lib/thunderbird-2.0.0.18/libgtkembedmoz.so
So if you have thunerbird 2.0.0.14 please make the change in the script as well.
Hope this help ;-)
