Other instructions

These packages have not necessarily been created by any of the developers of Minetest. Contact the authors of the packages in case of problems (at first).

NOTE: Do not use daily/unstable versions on servers or persistent worlds, they can sometimes corrupt the world.

If your distribution is not listed here, you can get the source code and compile Minetest-c55 yourself.

If you have packaged Minetest-c55 for some other distribution, contact me so I can link to it.

Others

There exists a FreeBSD port. It is quite outdated as of 2012-01-19.

It is known to compile relatively easily on OpenBSD at least. It should work quite fine on all platforms on which Irrlicht works.

Compiling

For Windows, look in doc/README.txt

For Linux, it is easy. Here is an example for Debian/Ubuntu:
Note that the minimum supported version of Irrlicht is 1.7.0.

Install dependencies:
$ apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev
Download source, extract:
$ wget https://github.com/celeron55/minetest/tarball/master -O master.tar.gz
$ tar xf master.tar.gz
$ cd celeron55-minetest-286edd4 (or similar)
Build a version that runs directly from the source directory:
$ cmake . -DRUN_IN_PLACE=1
$ make -j2
Run it:
$ cd bin
$ ./minetest
