I recently started reading [[http://www.nostarch.com/assembly2.htm][The Art of Assembly Language, 2nd
|
||
|
|
Edition]]. It uses High-Level Assembly language in its code examples
|
||
|
|
and this requires a special compiler, or assembler, to turn your
|
||
|
|
code into machine code.
|
||
|
|
|
||
|
|
** Fixing the PKGBUILD
|
||
|
|
|
||
|
|
The compiler, ~hla~, is available on the Archlinux User Repository
|
||
|
|
[[https://aur.archlinux.org/packages/hla/][here]]. At the time of writing, though, that ~PKGBUILD~ doesn't work
|
||
|
|
entirely. By default pacman removes all static libraries from the
|
||
|
|
created packages, which took me a while to find out. Adding the
|
||
|
|
following line to the ~PKGBUILD~ fixes it:
|
||
|
|
|
||
|
|
#+BEGIN_SRC sh
|
||
|
|
options=(staticlibs)
|
||
|
|
#+END_SRC
|
||
|
|
|
||
|
|
I also placed a comment on the AUR page, but there has been no sign
|
||
|
|
of acknowledgment so far.
|
||
|
|
|
||
|
|
** Running on x86_64
|
||
|
|
|
||
|
|
After having installed the compiler I got a lot of errors compiling
|
||
|
|
my very simple hello world application, as typed over from the
|
||
|
|
book. The gist of them was that it couldn't create 64-bit
|
||
|
|
executables, which isn't very surprising as HLA seems to be only
|
||
|
|
for x86 (32-bit) architecture. Another comment on the AUR page
|
||
|
|
helped that though. One should add the ~-lmelf_i386~ switch to the
|
||
|
|
~hla~ command-line. So I put in my =~/.zshrc=:
|
||
|
|
|
||
|
|
#+BEGIN_SRC sh
|
||
|
|
alias hla="hla -lmelf_i386"
|
||
|
|
#+END_SRC
|
||
|
|
|
||
|
|
This discovery only came after a few other attempts to install HLA.
|
||
|
|
|
||
|
|
** Alternative: Using Vagrant
|
||
|
|
|
||
|
|
Before I'd read about the ~-lmelf_i386~ command-line switch I was
|
||
|
|
looking at ways to run a 32-bit operating system inside my
|
||
|
|
Archlinux installation. There are a few options I'm familiar with:
|
||
|
|
lxc, Docker and Vagrant.
|
||
|
|
|
||
|
|
At first I tried to create a 32-bit Archlinux container, but the
|
||
|
|
installation script failed, so I couldn't get that started. Then I
|
||
|
|
went on to Vagrant, which worked pretty quickly.
|
||
|
|
|
||
|
|
I used the ~ubuntu/trusty32~ box, which can be downloaded by calling:
|
||
|
|
|
||
|
|
: vagrant box add ubuntu/trusty32
|
||
|
|
|
||
|
|
A very short ~Vagrantfile~:
|
||
|
|
|
||
|
|
#+BEGIN_SRC ruby
|
||
|
|
# -*- mode: ruby -*-
|
||
|
|
# vi: set ft=ruby :
|
||
|
|
|
||
|
|
Vagrant.configure(2) do |config|
|
||
|
|
config.vm.box = "ubuntu/trusty32"
|
||
|
|
config.vm.provision :shell, path: "vagrant.sh"
|
||
|
|
end
|
||
|
|
#+END_SRC
|
||
|
|
|
||
|
|
and then the provision in ~vagrant.sh~:
|
||
|
|
|
||
|
|
#+BEGIN_SRC sh
|
||
|
|
wget http://www.plantation-productions.com/Webster/HighLevelAsm/HLAv2.16/linux.hla.tar.gz
|
||
|
|
tar --directory / --extract --file linux.hla.tar.gz
|
||
|
|
|
||
|
|
cat > /etc/profile.d/hla.sh <<EOF
|
||
|
|
#!/usr/bin/bash
|
||
|
|
|
||
|
|
export hlalib=/usr/hla/hlalib
|
||
|
|
export hlainc=/usr/hla/include
|
||
|
|
export hlatemp=/tmp
|
||
|
|
export PATH="${PATH}:/usr/hla"
|
||
|
|
EOF
|
||
|
|
#+END_SRC
|
||
|
|
|
||
|
|
After that you can just call ~vagrant up~, wait a while and then have
|
||
|
|
fun playing around with HLA in an Ubuntu 14.04 environment.
