How to comiple a single C file in Nios

[Altera_Forum]

When I right click a C file and choose "Build selected file(s)", an error message turned up which says "..Operation not enabled".

Try going through one of the included examples and/or tutorials. You have to create a Nios II project, compile it, and then "Run" or "Debug" the result on a target board. 

 In general, you can't do what you're asking to do unless you're already _running_ in the runtime environment that you'd like to compile for... i.e.: Compiling a program for Windows while running in Windows...same for Linux.  Regards,  slacker

I just want to compile a single C file in the project.

I have seen a lot of errors in the Nios tools, this one is new for me :) 

What do the details say when you try to clean the project?  Have you tried building the Hello World example??

Certainly my experience of the IDE is that it did rather like running the compiler! Which wouldn't quite be so bad if the tcl (or whatever) actually ran an a sane speed! 

 However I switched my build environment to vi+make so don't have that problem any more! Made easier by the fact that I don't need any of the Altera tools to get my code onto the fpga.
