xilinx ise 12.4 + ubuntu 11.04 64bit + isim

October 28, 2011 Leave a comment

Xilinx ISE 12.4 on Ubuntu 11.04 64bit. When trying to run a testbench with ISIM, I got the following error:

FATAL_ERROR:Simulator:Fuse.cpp:209:1.124.4.5 – Failed to compile one of the generated C files.

Got the solution here.
Just delete the “libstdc++.so*” files in /opt/Xilinx/VERSION_NUMBER/ISE_DS/ISE/lib/lin64/.

ubuntu persistent environment variables

October 15, 2011 Leave a comment

As stated here, the recommended way to set (persistent) environment variables on Ubuntu is by editing the file “/etc/environment”.
To set temporary environment variables use the “export” command.
Example: “export PATH=$PATH:/new/path”

shared libraries on linux

  1. Go to “/etc/ld.so.conf.d/”
  2. Create a file with “.conf” extension (eg. “qwt.conf”)
  3. Open it with a text editor and add a line with the path of your library (eg. “/usr/local/qwt-6.0.0/lib”)
