ghdl and compatibility with linux pseudoterminal

[Dale Scott]

Hi, I am trying to use the ghdl package to simulate a micro-coded
cpu/sequencer[1] included as part of a FPGA design. The vhdl model for the
cpu uses a pseudo-terminal[2] to communicate with the outside world (e.g.
using minicom), and ghdl gives an error compiling the cpu with the
pseudo-termnal code. Any suggestions? (or a more appropriate list?).

ghdl: compilation error

Fwiw, I had to comment out the "#include <linux/ioctl.h>" in ghdl_pty.c as
"<linux/ioctl.h> not found".

 

Thanks,
