Hallo,
I use Linux suse 11.4. 64bit and precompiled GHDL in 32bit mode.
In my makefile I have to use the -Wa,--32 and the -Wl,-m32 this works nice.
ghdl -a -Wa,--32 --work=work --workdir=work
../rtl/memory/ahb_memory.vhd
ghdl -e -Wa,--32 -Wl,-m32 --ieee=synopsys -fexplicit --workdir=work
-Pwork tb_lm_cpu
now I want to link VHPI C funtions together.
I tried out the files from myhdl
http://www.myhdl.org/lib/exe/fetch.php/dev:vhdl_cosim:vpi-ex.tar.gz
The makefile have been adapted this options.
-----Makefile-------------------------------
CC=gcc
CFLAGS=-Wall -g -I.
all: run-vpi
myhdl_vpi.o: myhdl_vpi.c
$(CC) -c -fPIC $(CFLAGS) myhdl_vpi.c
myhdl.vpi: myhdl_vpi.o
$(CC) --shared -o myhdl.vpi myhdl_vpi.o
disptree:
ghdl -a -Wa,--32 disptree.vhdl
ghdl -e -Wa,--32 -Wl,-m32 -Wl,-Wl,-E disptree
run-vpi: myhdl.vpi disptree
./disptree --vpi=./myhdl.vpi
clean:
rm -f myhdl_vpi.vpi
rm -f *.o
tar:
tar cvf vpi-ex-ghdl.tar myhdl_vpi.c Makefile vpi_user.h
------------------------------------------------------------------------------------------------------------------
I got an error.

Second atempt with a library.

I got also an Error.
Have you any suggestion for linking such files?????
Thank you René
