Im' using Quartus 4 and SOPC Builder 4. I'm preparing a nios design, but i've got a trouble with software build.

The point is that the only way I have to generate the soft is to regenerate the whole system (both soft and hard).

I obviously tried to use the command line tools, in vain. I tried to use the c macro offered in the generated modelsim do file ... but it's still not working ...

Here is the error i have in the SOPC SDK SHELL when try to build montest.c code :

[SOPC Builder]$ nios-build montest.c Can't use string ("-1") as a HASH ref while "strict refs" in use at - line 478.

And attached is the log of the modelsim shell.

If anybody has an idea from where it comes from, please let me know.

Thanks for your attention.

I seem to recall that I got this message when I used the wrong perl installation. You have to make sure that you use the included cygwin and perl distriutions.

I got this error when my c source was not in the cpu_sdk/src directory. I moved my source to that directory under my project now all is better. Let me know if it works for you.

If you have your apps engineer on speed dial.......You might be designing with Altera. hahahaha For you Xilinx guys just do the subsituition.
