This file documents the Linux/x86 and Linux/x86_64 ports.
For the Linux/AArch64 (ARM64) port, see REAMDE.Linux-aarch64.
For the Linux/PowerPC port, see README.Linux-PPC.
(Ports to Linux on other architectures have not yet
been attempted, but should not be difficult.)


BUILDING A 32-BIT MERCURY COMPILER ON 64-BIT LINUX
==================================================

To build a 32-bit Mercury compiler on 64-bit Linux, follow these steps:

(1) Ensure that the 32-bit (e.g. i686 etc) packages for the C compiler and
    libraries are available on the build system.

(2) Ensure that you have a working Mercury compiler in your PATH
    to bootstrap from.

(3) Run aclocal -I m4; autoconf as normal.  Then invoke configure
    as follows:

        $ ./configure --host=i686-pc-linux-gnu --with-cc="gcc -m32"

(4) Do mmake; mmake install as normal.
