Build errors

Hi to all!I am trying to build a packet switch for a project i am assigned and i have the following errorS

Any help will be appreciated

Have you tried this?

[stzog]

No..

Ok Thanx a lot!!!I solved it following your advice!!But what was the problem???

[apfitch]

There was no problem.  Right at the bottom of the messages you'll see "Generating Code", so your program did compile.

P.S. , The warnings were the nice people at Microsoft telling you that the function sprintf is potentially unsafe (as it doesn't have any bounds checking).

"sprintf" is a very powerful function to write a sequence of bytes

according to specified format into a buffer. Most importantly, as

the OP is trying to model a packet switch, and packets are always

of a certain size, the size constraint must be rigorously enforced

by the packet switch, and in fact in real world devices,extra bytes

are put into a separate packet, to enforce the rule. Hope that

helps.

Ok thanks o lot for your precious help.

I have managed to run succesfully the switch in systemc according to its specifications.

One more question...

Is there any  way to implement the switch in VHDL consdering that i have the SystemC code???
