[myhdl-list] compiling generated VHDL code

[Martín G. <ga...@gm...>]

Hi,

I've been working on my project for the university (I called it
"pymips"). Now I know (with a bit effort) how to code convertible
things. But I don't know why the code I get fails when I try to
compile it.

For example, the converted version of the alu
http://github.com/nqnwebs/pymips/blob/master/alu.py

is this

http://github.com/nqnwebs/pymips/blob/master/vhdl/alu.vhd

when I try to compile or check that I get this:

(hdl)tin@azulita:~/facu/arq/project/vhdl$ ghdl -a alu.vhd
alu.vhd:31:22: no function declarations for operator "and"
alu.vhd:33:22: no function declarations for operator "or"
/usr/lib/ghdl/bin/ghdl: compilation error

what's wrong?

thanks
Martín
