Notes on compiling preForth on Ubuntu 2404LTS

[cstrotm]

I was able to compile PreForth and seedForth under Ubuntu 24.04LTS with these steps:

apt install emacs-nox git build-essential tmux fasm gforth
dpkg --add-architecture i386
apt update
apt install libc6-dev-i386

git clone https://github.com/uho/preForth
cd preForth/src

edit Makefile and change the "ld" linker command to:

# assemble and link executable on linux
%.Linux: %.asm
        fasm $< [email protected]
        LDEMULATION=elf_i386 ld -melf_i386  -o $@ \
           -dynamic-linker /lib32/ld-linux.so.2 \
           /usr/lib32/crt1.o /usr/lib32/crti.o \
           [email protected] \
           -lc /usr/lib32/crtn.o
        # rm [email protected]  

Then compile:

make clean
make

and start seedForth

./seed

Ah ... the trick is to have the i386 headers - that's why it didn't work here. Thanks!!

OK - I have it compiling but it segfaulted - I'll try with gdb tomorrow.
