#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: $INSTALL_DIR/Xilinx/14.4/ISE_DS/ISE/bin/lin/ise #starting coregen: $INSTALL_DIR/Xilinx/14.4/ISE_DS/ISE/bin/lin/coregen
Issues:
- When first starting ise, it will ask for a license by starting a browser (chromium on my system). But as it sets the LD_LIBRARY_PATH variable to Xilinx-compiles stdc++ library, chromium-browser cannot start start. I fixed this with:
cd /usr/lib/chromium-browser mv chromium-browser chromium_browser_ cat > crhomium-browser <<EOF #!/bin/bash LD_LIBRARY_PATH= set > /tmp/set /usr/lib/chromium-browser/chromium-browser_ "$@" 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.
