Maintenance of Miranda

The Miranda source code is now maintained on codeberg.org/DATurner/miranda

This is particularly relevant because the last binary release on miranda.org.uk was of mira 2.042 in Sep 2008 and since then Professor Turner only released it in source code form, of which his latest is 2.066 from Jan 2020, but those releases do not compile out of the box.

To build it from source, you need make and a C compiler. If you need to modify rules.y you'll also need byacc; it does not work at all with the supposedly compatible GNU bison.

It is known to work on aarch, amd, arm, chrp, evbarm, loongarch, mips, powerpc, riscv and x86, on 32-bit and 64-bit, big-endian and little-endian systems running AIX, AlmaLinux, AlpineLinux, Archlinux, CentOS, Debian, FreeBSD, Haiku, MacOS X, NetBSD, OpenBSD, OpenSUSE and Rocky with all versions of GCC from 2.95 to 14 and clang 11 to 16 with no optimization enabled and some versions of gcc and clang up to -O3. The 64-bit version has been tested with up to 2TB of RAM for the heap, over 100,000,000,000 cells.

You can see whether optimization will work for you in the table "Compilers" in #25

It compiles but does not work on Solaris with a sun4u processor and a Windows port has not yet been attempted.

A release will be made on Codeberg when further portability and testing are complete, currently scheduled for 1st May 2025.

In the meantime, you can

git clone https://codeberg.org/DATurner/miranda
cd miranda
make
make install

which puts it in /usr/bin/mira and /usr/lib/miralib. To install it elsewhere or use a different compiler than GCC, edit Makefile before building.

You can also test it in the source directory before installing it by running it as ./mira

There is a mailing list miranda@groups.io whose web site is http://groups.io/g/miranda and you can also subscribe to it by sending an email to miranda+subscribe@groups.io

His earlier language, KRC, is maintained at codeberg.org/DATurner/KRC
