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. As the licence manager doesn't inform the user of the crashed browser, simply nothing happens after clikcing the 'get licence' (or whatever it was called) button. I fixed this with:
cd /usr/lib/chromium-browser
mv chromium-browser chromium_browser_
cat > chromium-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.

Cannot compile generated C files

When trying to simulate, the simulator responds with errors; the fix was to use gcc-4.4 (maybe the problem started after I upgraded to Ubuntu 13.04, it also persists in 13.10) 

Waiting for 2 sub-compilation(s) to finish...
FATAL_ERROR:Simulator:Fuse.cpp:209:1.133 - Failed to compile one of the generated C files.

   Please recompile with -mt off -v 1 switch to identify which design unit failed.  Process will terminate. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support.

Process "Simulate Behavioral Model" failed

When running the last mentioned with added -mt off -v 1, I get these messages:

Installing gcc-4.4, and symlinking gcc to gcc-4.4, 

aptitude install gcc-4.4
cd /usr/bin/
ln -sf gcc-4.4 gcc

fixed it the compilation error. I did have to remove the isim dir in the top level project dir, to remove the linking errors: 

gcc-4.4.real: isim/precompiled.exe.sim/ieee/p_2592010699.lin.o: No such file or directory

So, now everything is working again.
