Quartus 8.1 on Linux

[Altera_Forum]

We have an old development project running with Quartus V8.1 which works fine on XP. 

 Our new development PCs are Windows7 which is unsupported with Quartus, so I thought I'd try running the Linux version.   I've downloaded and installed the NIOS IDE/Quartus II and I can see everything is in /opt/altera81, but when I load the project into Eclipse it won't compile!  It looks like the path to the nios2-elf-gcc (and the other tools) can't be found. Is there a script or something that I need to run before loading the IDE? There seems to be several snippets, but nothing that works properly.  Can anyone help me?

Try adding the following directories to your path: (Of course using the correct install directory for your 8.1 install..) 

 /opt/altera/11.1/quartus/sopc_builder/bin/: /opt/altera/11.1/nios2eds/bin: /opt/altera/11.1/nios2eds/sdk2/bin: /opt/altera/11.1/nios2eds/bin/gnu/H-i686-pc-linux-gnu/bin:   Of course for longevity, I would try to migrate to the newest tools, but if that isn't possible, a Virtual Machine is a nice way to archive old projects. Generate a VM with Windows XP and all the tools you need, and build it in that. (Vmware player is free! and works great!)  Pete
