Nice hint, thanks! This works:
% ghdl -a hello.vhdl
% /home/hanzer/local/libexec/gcc/i386-unknown-freebsd10.1/4.9.2/ghdl1 \
-P/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/v93/std/ \
-P/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/v93/ieee/ \
--elab hello -l e~hello.lst -quiet -o e~hello.s e~hello
% /usr/local/bin/as -o e~hello.o e~hello.s
% /home/hanzer/local/bin/gcc -o hello e~hello.o \
/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/v93/std/std_standard.o
\
/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/v93/std/textio.o
\
/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/v93/std/textio_body.o
\
hello.o \
/home/hanzer/local/lib/gcc/i386-unknown-freebsd10.1/4.9.2/vhdl/libgrt.a -lm
-L./ -lz
% ghdl -r hello
Hello world!
I'm not sure if I understand the implications of this. Any additional guidance
or insights will be greatly appreciated!
Ref:
% cat hello.vhdl
use std.textio.all;
entity hello is
end hello;
architecture behaviour of hello is
begin
process
variable l : line;
begin
write (l, String'("Hello world!"));
writeline (output, l);
wait;
end process;
end behaviour;
