#Installing libXm.so.3:
sudo apt-get install libmotif3

#Set the env variables:
INSTALL_DIR=/opt

. $INSTALL_DIR/Xilinx/14.4/ISE_DS/settings32.sh
export XIL_CG_LOAD_ALL_FAMILIES=true
DISPLAY=:0

#starting the main app:

#starting coregen:
$INSTALL_DIR/Xilinx/14.4/ISE_DS/ISE/bin/lin/coregen

Issues (14.4)

• When first starting ise, it will ask for a license by starting a browser (chromium on my system). But as it sets the LD_LIBRARY_PATH variable to Xilinx-compiles stdc++ library, chromium-browser cannot start start. I fixed this with:

cd /usr/lib/chromium-browser
mv chromium-browser chromium_browser_
cat > crhomium-browser <<EOF
#!/bin/bash
LD_LIBRARY_PATH=
set > /tmp/set
/usr/lib/chromium-browser/chromium-browser_ "$@"
EOF
chmod a+x chromium-browser.

This will of cause stop working after the next update of chromium-browser.

• Coregen doesn't load the full IP library (or something). Fixed this with the XIL_CG_LOAD_ALL_FAMILIES=true environment variable above. If you don't do this, the IP Core generator gives these messages in the console:

ERROR:encore:372 - Failed to set default project options.
ERROR:sim:569 - Failed to set default project options.
ERROR:encore:268 - Project /home/joostje/VHDL/Ltest/coregen_xil_1hPILG.cgc could not be opened
ERROR:encore:312 - Couldn't create new project.

• Simulation fail:

Don't know the solution to this one yet, when trying to simulate (maybe it started happening after I upgraded to Ubuntu 13.04)
